Types of mobile phone batteries and how to use them 10

At present, mobile phone batteries are mainly divided into three categories: nickel-cadmium batteries, nickel-metal hydride batteries, and lithium-ion batteries.

Nickel-cadmium batteries are made up of two plates: one made of nickel and the other made of cadmium, and these two metals react reversibly in the battery so that the battery can be recharged. Its best feature is its sturdiness and long talk time.

However, due to the memory effect, it is currently used less.

NiMH batteries have another name called environmentally friendly batteries because it does not contain cadmium metal and does not pollute the environment. It has a 30% to 50% more power reserve than nickel-cadmium batteries, and the talk time of mobile ** is also extended by 30%, which is more widely used because ** is cheaper.

Lithium-ion battery is a high-energy density battery, which has a larger power reserve and lighter weight than nickel-cadmium batteries and nickel-metal hydride batteries of the same size. Lithium-ion batteries are also a smart battery that must be charged with a dedicated smart charger to achieve the shortest charging time and longest life cycle and maximum capacity.

The most used in mobile phones is lithium-ion batteries, mobile phone lithium-ion batteries need to pass the test to apply, generally use high-current shrapnel microneedle module for current conduction and connection, up to 50A current transmission and stable connection, can improve the test efficiency of mobile phone lithium batteries, but also to cope with high-frequency test needs.

Commonly used batteries are: nickel-cadmium batteries, nickel-metal hydride batteries and lithium-ion batteries.

Nickel-cadmium batteries. Nickel-cadmium batteries are the first generation of mobile phone batteries that consist of two plates, one made of nickel and the other made of cadmium, these two metals react reversibly in the battery, so the battery can be recharged. However, it has a low capacity, has a memory effect, needs to be discharged frequently to maintain the capacity, and there is environmental pollution in the manufacturing materials, and this kind of battery has been basically eliminated at present.

NiMH batteries. The second-generation NiMH battery has a capacity of 30 to 50 more than NiCd batteries, and the talk time of mobile** is also increased by 30 as a result. Its manufacturing materials have little environmental pollution (does not contain cadmium metal), and people are accustomed to calling it an environmentally friendly battery. However, NiMH batteries also have self-discharge, and at normal room temperature, the power loss rate of NiMH batteries is 1 3% per day, and a fully charged NiMH battery should be recharged before use after a few weeks of sitting.

Lithium-ion batteries.

No memory effect, no need to discharge, long service life.

High operating voltage. Usually the voltage of a single lithium-ion battery is 3 times the voltage of nickel-metal hydride and nickel-cadmium batteries.

Small size, light weight, high specific energy. The specific energy of lithium-ion batteries can be more than twice that of nickel-cadmium batteries. with the same tolerance.

Compared with nickel-metal hydride batteries, the volume can be reduced by 30% and the weight can be reduced by 50%.

Long lifespan. The life of high-quality lithium-ion batteries can reach more than 1,000 times, which is much higher than that of other types of batteries.

Safe and fast charging. Lithium-ion batteries are treated with a special technology that allows them to be fully charged quickly within 3 hours, and the safety performance is greatly improved.

Wide operating temperature range is allowed. Lithium-ion batteries can operate between stacked glass and A-Rana +60. The high-temperature discharge performance is better than that of other types of batteries.

1. Nickel-cadmium battery. The most fatal disadvantage of nickel-cadmium batteries is that if they are not handled properly during charging and discharging, there will be a serious "memory effect", which greatly shortens the service life. The so-called "memory effect" is that the battery is not completely drained before charging, and over time it will cause the battery capacity to decrease, and in the process of battery charging and discharging (the discharge is more obvious), some small bubbles will be produced on the battery plates, and over time, these bubbles reduce the area of the battery plates and indirectly affect the capacity of the battery.

Of course, we can mitigate the "memory effect" by mastering reasonable charging and discharging methods. In addition, cadmium is toxic, so nickel-cadmium batteries are not conducive to the protection of the ecological environment. Due to numerous shortcomings, nickel-cadmium batteries have been basically eliminated from the application range of digital device batteries.

The fuller the battery is charged, the higher the self-discharge rate; When the charge drops to a certain level, the self-discharge rate decreases slightly. The temperature of the battery storage has a significant impact on the self-discharge rate. Because of this, nickel-metal hydride batteries that have not been used for a long time are best charged to 40% "half full".

3. Polymer-ion batteries. Lithium-ion batteries with polymer cathode materials use conductive polymers as cathode materials, and their specific capacity is relatively increased. Due to the replacement of liquid electrolyte with solid electrolyte, compared with liquid lithium-ion batteries, polymer lithium-ion batteries have the advantages of thinning, arbitrary area and arbitrary shape, so the battery shell can be manufactured with aluminum-plastic composite film, so that the specific capacity of the whole battery can be improved. Polymer lithium-ion batteries can also use polymers as cathode materials, and their mass specific energy will be increased by more than 20% compared with the current liquid lithium-ion batteries.

Polymer lithium-ion battery (Polymer Lithium-ion Battery) batteries are miniaturized, thinner, and lighter. Therefore, the market share of polymer batteries will gradually increase.

1. Maintain the battery.

A maintenance battery is a battery that the user replaces back. For example, if the small manufacturer disassembles and repairs the battery and then leaves the factory, such a battery is called a maintenance battery.

The general maintenance battery is guaranteed for 2 months, and the batteries returned to the factory by large manufacturers such as Tianneng and Chaowei are not repaired, and the lead inside is directly redone, that is, the lead inside is not purified. Sometimes the maintenance battery can also be used for a year or two.

2. Turnover battery: turnover battery, maintenance battery: refurbished.

Turnover batteries and maintenance batteries are used batteries.

Refurbished batteries that have been recharged and discharged to meet discharge standards.

However, the mobile phone battery should be used better, focusing on its maintenance and maintenance, the landlord can focus on this, in fact, how to say it, the battery wants to be used for a long time, it must be to develop good charging habits.

First, don't wait until the battery is completely empty before recharging, but don't overcharge it continuously for a long time.

Battery Manager has a variety of power-saving modes to make your phone more effective in saving power.

Intelligently and dynamically adjust the CPU frequency to bring deep energy saving, power saving, and charging and maintenance functions.

Comprehensively identify the three defects and different charging stages to help you save charging time and extend the life of the battery so that it can be used again.
