Storage of nickel cadmium and nickel metal hydride batteries

Store again after a full charge. When you take it out in the future, it is best to charge and release it several times before the capacity can be restored. You can buy the kind of charger with automatic point function.

The preservation of nickel-metal hydride batteries needs to pay attention to the following two points:

1.Storage Environment Empty Draft Temperature Conditions: When the temperature is too high, the battery will lose its ability to charge.

When storing NiMH batteries, it is important to remember that the temperature of the storage area should not be too high. Conventional NiMH batteries need to be stored at room temperature (25°C 3°C). Special Attention:

Keep NiMH batteries in the sun and store them in any cool, dry room. It is important to remember that batteries will self-discharge when placed.

2.NiMH battery storage environment humidity conditions: high humidity is not conducive to the storage of electrochemical cells.

The ideal humidity level is 35% to 65%. Steam-resistant vessels are an option to keep them away from high humidity environments. Special Attention:

In short, the preservation of nickel-metal hydride batteries requires temperature and humidity control, avoiding high temperature and high humidity environments, while paying attention to protection from direct sunlight and mechanical vibration.

For nickel-metal hydride batteries that you want to not use for a long time.

It is necessary to remove it from the appliance and then fully charge it before storing it, otherwise after a long period of time, when you want to use these batteries again, you will find that the batteries are broken, and this is because the batteries are overdischarged. The best condition for the preservation of nickel-metal hydride batteries is to store about 80% of the charge. This is because the self-discharge of nickel-metal hydride batteries is large (about 10-15% a month), if the battery leaves the factory without electricity, and the battery is not used for a long time (if it is not sold), the self-discharge phenomenon of the battery will cause the over-discharge of the battery, which will damage the battery.

Therefore, when the new battery leaves the factory, it is fully charged and shipped out of the factory (at least 80-90% full), so when you get the new electric silver open pool, the battery is generally charged, and the closer you get it to the production date, the more residual power the battery will have (sometimes the battery you get is 10-20 days away from the production date, then the battery is basically full).

The national standard for the cycle life of nickel-metal hydride batteries is 500 times (80% DOD), and the company advertises 1000 times, which can be achieved by a single battery. NiMH rechargeable batteries can be used for more than 5 years. The memory effect of NiMH batteries is very small and negligible.

Theoretically, the life of nickel-metal hydride batteries is slightly longer than that of nickel-cadmium batteries, both of which are more than 5 years, but when nickel-metal hydride batteries are overcharged, the adverse effects on the battery are greater than those of nickel-cadmium batteries. The so-called correct charging is to make 100% of the capacity of the rechargeable battery play out without damaging the battery. Incorrect charging has two consequences, the capacity cannot be 100% exerted, and the battery is seriously damaged.

Although the memory effect of nickel-metal hydride batteries is small, it is still recommended that you try to recharge them after each use, and they are fully charged at one time, not charged for a while and then charged. This is an important part of longevity.

Generally, the number of cycles of nickel-metal hydride batteries is 800 times and 1200 times; Batteries with low cycle times have high internal resistance and poor performance, so many cheap batteries generally have low cycle times. Therefore, to measure whether a battery is good or not, we cannot simply pursue how high the capacity is, but comprehensively consider the battery capacity and the number of cycles.

Hello: 1. Any new battery (including battery).Life nominal value] are all based on [Number of charge and dischargeshall prevail.

2. Different brands and different capacities of batteries, the service life (number of charge and discharge) is slightly different, you can check the product manual.

Nickel-cadmium battery is a type of battery that has the characteristics of short charging time, high energy density and high output capacity, so it is often used in industrial, medical and military fields. Its storage longevity is related to factors such as the charging method taken, the use environment and the number of times of use. Here's a breakdown of the common factors:

1.Charging method: Regular floating charging can reduce the self-discharge rate of the battery, while overcharging and over-discharging will accelerate the corrosion and aging of the electrode and electrolyte, thereby reducing the service life.

2.Environment: The battery is easy to age at higher temperatures and humidity, and it is not easy to charge in cold environments, thus shortening the lifespan.

3.Number of uses: Frequent charging, discharging and incomplete charging will form crystals, sulfides between the plates and plates, resulting in shortened storage life.

Generally speaking, the life of the nickel-cadmium battery can be controlled by controlling the above factors to a certain extent, and some preventive measures can also be taken, such as cleaning the electrode plate regularly, appropriately shortening the storage time, and avoiding sharp current discharge. Under the condition of normal use and maintenance, the storage life of nickel-cadmium batteries can reach more than 2 years.

Nickel-cadmium battery is a common battery, and its life is mainly affected by the following factors: working voltage range and charging mode, discharge depth and rate, non-collapse temperature, number of cycles and dead circle time. Among them, temperature is an important factor restricting the service life of the battery, and a higher temperature will accelerate the aging process of the battery and shorten its life.

Under normal circumstances, the storage life of nickel-cadmium batteries is generally about 1-2 years, and the actual service life depends on the specific use. Therefore, in the process of normal use, it is necessary to charge and discharge correctly, avoid overcharging and discharging, control the discharge rate and depth, and avoid placing the battery in a high or low temperature environment for a long time, so as to prolong the service life of the brigade length battery.

Nickel-cadmium-based positive battery is a commonly used secondary battery, which has good performance in environmental protection, economy and service life. The storage life of the battery is mainly affected by factors such as the storage environment and service life of the battery. Generally speaking, if stored in a dry, suitable temperature, and dark environment, without excessive discharge, this battery life can reach 5 years.

However, if it is not used for a long time, there may be self-discharge or other problems inside the battery, which will affect the service life. Therefore, we need to use and store the battery reasonably to ensure its normal use.

The storage life of the pot nickel battery is 3-5 years.

This is because during long-term storage, due to self-discharge and temperature changes, there will be electrochemical reactions, resulting in a decrease in battery capacity and performance, which in turn affects the battery life. In addition, there is also a "polarization phenomenon" in the pot nickel battery, that is, in the process of discharging and charging, there will be an electrochemical reaction, resulting in the occurrence of polarization, the more times the electrochemical reaction, the more likely the performance of the battery will be reduced, and the life will be shortened accordingly.

In order to prolong the storage life of the nickel battery in the simple pot, we can take the following measures: first, choose a dry, ventilated, dark and suitable temperature environment during storage to reduce the impact of self-discharge and temperature changes on the battery cavity pants; Second, batteries that have not been used for a long time need to be recharged regularly to prevent the battery capacity from losing too quickly.

It should be noted that if there is leakage, deformation, odor and other abnormal conditions during the storage of the pot nickel battery, it should be stopped immediately to avoid safety accidents.

In a word, the storage life of the pot nickel battery is affected by a variety of factors, which require us to pay attention to it when using and storing it to prolong the service life of the battery.

Nickel-cadmium battery (Ni-Cd battery) is a rechargeable battery composed of a nickel-metal hydride (NiMH) cathode, cadmium hydroxide (CD) anode, and an alkaline electrolyte.

Nickel-cadmium batteries have the following characteristics:

High cycle life: Nickel-cadmium batteries have a high charge-discharge cycle life, typically up to thousands of charge cycles.

Stable voltage output: Ni-cadmium batteries provide a relatively stable voltage output during discharge, which is suitable for applications that require stable voltage for a long time.

Good charging performance: Nickel-cadmium batteries have good charging performance and can be fully charged in a short time.

Good high temperature resistance: Nickel-cadmium batteries have good high temperature resistance characteristics and are suitable for applications in high temperature environments.

Higher energy density than spike rolling: Compared with some other rechargeable batteries, nickel-cadmium batteries have a higher energy density and are able to provide a longer service life.

However, there are also some shortcomings in the nickel hall good cadmium battery

There is a memory effect: If there are frequent incomplete charge-discharge cycles, nickel-cadmium batteries may have a memory effect, resulting in a decrease in usable capacity.

Chemical toxicity: Cadmium in nickel-cadmium batteries is a toxic substance that can cause harm to the environment and human health if not handled properly.

Low specific energy: Compared with some newer batteries, nickel-cadmium batteries have relatively low specific energy, limiting their application in specific fields.

Due to the environmental and health risks of nickel-cadmium batteries, as well as the limitation of energy density, they have been used by other types of rechargeable batteries, such as lithium-ion batteries and nickel-metal hydride batteries, in many applications.

For nickel-cadmium batteries, cadmium Cd is the negative electrode and NiO(OH) is the negative electrode.

Total reaction: 2NiO(OH)+CD+2H2O== Discharge==2Ni(OH)2+Cd(OH)2

Charging is written in reverse: 2Ni(OH)2+CD(OH)2== Charging core mu==2NiO(OH)+CD+2H2O

Positive electrode: 2NiO(OH)+2H2O+2 electron pie ===2Ni(OH)2+2OH- (OH- is hydroxide).

Negative modification: cd-2 electrons +2oh- = cd(oh)2

Summary. Nickel-cadmium batteries and nickel-pick batteries are not exactly the same, although they both belong to the nickel series of batteries. Nickel-cadmium batteries use nickel and cadmium as cathode and anode materials, while nickel-pick batteries use nickel, pickaxe, and iron as cathode and anode materials.

There are also some differences in the working principle and performance characteristics of these two batteries. Nickel-cadmium batteries have high charge-discharge efficiency, good high-temperature resistance and long life, but they have the problems of environmental pollution and memory effect. The nickel pickaxe battery has relatively better environmental performance and higher capacity density, but it is higher and prone to self-discharge.

In general, nickel pick batteries may be more suitable for use in some specific application areas, but depending on the needs and scenarios.

Fellow, I really didn't understand, I can be more specific.

Although nickel-cadmium batteries and nickel-pick batteries are both nickel-based batteries, their cathode and anode materials, working principles and properties are different. Nickel-cadmium batteries have high efficiency, high temperature resistance and long life, but they have the problems of environmental wax staining and memory effect. The nickel pickaxe battery is more environmentally friendly and has a high capacity density, but it is high and easy to self-discharge.

Therefore, which battery to choose depends on the needs and scenarios. Nickel pick batteries may be more applicable in some specific areas.

The voltage of the nickel-metal hydride battery will drop sharply when the power is about to run out, so you measure that its no-load voltage is lower or the load voltage is lower than the power is about to run out.

Nickel-metal hydride battery: It is composed of hydrogen ions and metal nickel, with 30% more power reserve than nickel-cadmium battery, lighter than nickel-cadmium battery, longer service life, and no pollution to the environment. The disadvantage of nickel-metal hydride batteries is that they are much more expensive than nickel-cadmium batteries, and their performance is worse than that of lithium batteries.

Nickel-cadmium batteries can be charged and discharged more than 500 times, which is economical and durable. Its internal resistance is small, the internal resistance is small, it can be charged quickly, and it can provide large current for the load, and the voltage change is very small when discharging, which is a very ideal DC power supply battery. Compared with other types of batteries, nickel-cadmium batteries can withstand overcharging or over-discharge.

The discharge voltage of nickel-cadmium batteries varies according to their discharge devices, and the battery capacity units of each cell are approximately ah (ampere-hours) and mAh (milli-ampere-hours), and the limit value of the discharge termination voltage is called "discharge termination voltage", and the discharge termination voltage of nickel-cadmium batteries is for each cell). The self-discharge rate is low, and the characteristics of the nickel-cadmium battery will not deteriorate in the case of long-term placement, and the original characteristics can be completely restored after full charging, and it can be used in the temperature range of 30 --50. Since the cell battery adopts a metal container, it is sturdy and durable; The electrolyte is completely sealed and there is no electrolyte leakage, so there is no need to replenish the electrolyte.

The key to improving battery performance and extending battery life is to avoid memory effects and over-discharge. Nickel-cadmium batteries have a memory effect, that is, after the nickel-cadmium battery is charged and discharged at several times of low capacity, if a larger capacity charge and discharge is to be carried out, the battery will not work normally, which is the memory effect. In particular, in video recorders and video cameras where the discharge end voltage is set, the battery capacity decreases as the operating voltage decreases, but the decrease in discharge voltage may be a temporary phenomenon caused by one or two complete discharges.

The memory effect makes the performance of the battery not be fully utilized, and it also brings great inconvenience to shooting. Therefore, attention should be paid to the use of chargers with charge-discharge performance, such as Sony's BC 1WDCE, to avoid the generation of memory effects. When using a general charger such as BC 1WA and BC 1WB, it can be discharged once after about 10 charges, and the purpose of preventing memory effect can also be achieved.
