Advantages and disadvantages of lead-acid batteries and lithium batteries

Lead-acid battery advantages:

Compared with lithium batteries, lead-acid batteries are relatively cheaper, higher than lithium batteries, and have better high-rate discharge performance.

Lead-acid battery disadvantages:

Lead-acid batteries are relatively heavier, and contain sulfuric acid and some heavy metal substances, which are corrosive and easy to cause environmental pollution; In addition, lead-acid batteries have a lower energy density and have less service life than lithium batteries.

Advantages of lithium battery:

Compared with lead-acid batteries, lithium batteries are smaller, lighter, more portable and have a relatively longer lifespan. In addition, lithium batteries have more energy, can provide larger current, and have stronger adaptability to high and low temperatures, are less affected by temperature, and are more environmentally friendly.

Lithium battery disadvantages:

The safety and stability of lithium batteries are relatively poor, and if they are not operated properly, there is a risk of **. In addition, lithium batteries cannot be discharged with high current, and the production requirements are high, and the cost is also higher.

Which is better, lead-acid battery or lithium battery

Lead-acid batteries and lithium batteries are good in their own way, and it is best to choose the one that suits you. Although lithium batteries have many advantages, at present, their technology is not perfect enough, and the initial products are often not mature. After years of precipitation, the lead-acid battery technology is more mature and cheaper, and it is relatively better in terms of source cavity sensitivity, and it has always been favored by users.

However, lithium battery is the future trend of the battery industry, and the technology is also improving step by step.

The difference between lead-acid battery and lithium battery, which battery will you choose after reading it?

Lead-acid batteries are generally used in two-wheelers and three-wheelers.

It is called a lead-acid battery because the electrolyte inside the battery is dilute sulfuric acid.

Lithium battery is a type of battery that uses lithium metal or lithium alloy as the anode material and uses a non-aqueous electrolyte solution. Due to the very active chemical properties of lithium metal, the processing, storage and use of lithium metal have very high environmental requirements. Therefore, lithium batteries have not been applied for a long time.

Lithium batteries generally have a nominal voltage higher than volts, which is more suitable for integrated circuit power supply. It is widely used in computers, calculators, cameras, and watches.

Lead-acid battery (VRLA) is a battery in which the electrode is mainly made of lead and its oxide, and the electrolyte is a sulfuric acid solution. In the discharged state of lead-acid battery, the main component of the positive electrode is lead dioxide, and the main component of the negative electrode is lead; In the charging state, the main components of the positive and negative electrodes are lead sulfate.

The device that converts the chemical energy of the battery into electrical energy is called a chemical battery, which is generally referred to as a battery. After discharge, the internal active material can be regenerated by charging - storing electrical energy as chemical energy; When an electric discharge is required, the chemical energy is converted into electrical energy again. This type of battery is called a storage battery, also known as a secondary battery.

The so-called storage battery is an electrochemical device that stores chemical energy and emits electrical energy when necessary.

Lithium-ion batteries are lightweight and have a high specific energy, but they are safe and cost-effective.

Lithium-ion batteries belong to rechargeable batteries, while lead-acid batteries do.

Alkaline battery: Lithium-ion battery has a cycle life of more than 2,500 times, and lead-acid battery has a cycle life of about 800 times. That is.

It is said that with the same weight, the lithium battery can run farther than the lead-acid battery. Therefore, in terms of energy density, lithium batteries are better than lead-acid.

Battery. From the perspective of service life, a group of good quality lithium batteries can reach about 1,000 cycles, while lead-acid batteries are only about one-third of lithium batteries. Therefore, in terms of service life, lithium batteries are better than lead-acid batteries.

Lead-acid batteries. 1: (Hard!) The lead-acid boss has always been in the spirit of being strong and strong, and the breeze is blowing on the hills. He let him be horizontal, and the bright moon shines on the river as the principle. Lead-acid batteries are easy to feed, let you fall and beat, repair a little, and you can continue to use.

2: (Cheap!) The reason why the lead boss has been able to dominate the battery community for many years and sit in the position of the boss is all because of this reason! Cheap. Except that it's cheap or cheap.

Lead-acid batteries can be used in.

The technology is hidden and the ability to use it can be changed to the electric cattle store after it is used badly.

You can replace it with a new set of batteries by making up the price difference, which minimizes the loss. It's a big benefit for users.

Lithium battery: 1: (light weight, small size) Lithium battery that has been working lightly since childhood.

Compared with lead-acid batteries of the same capacity on the market, the volume of lithium batteries is 2 3 of the volume of lead-acid batteries, and the weight is about 1 3 of the weight of lead-acid batteries. Lithium batteries of the same volume have more capacity than lead-acid batteries.

The high, weight reduction increases the range of the electric vehicle by about 1

0% or so. 2: (Life improvement) Lithium battery has won the way of health, the average life of lithium battery is about one year, about two times higher than the life of lead-acid battery, charging and discharging more than 500 times, the battery has no memory, and has strong shock resistance.

3: (overcharge resistance, good charge and discharge resistance) The lithium battery has opened up the eight veins of the Qi meridian since childhood, so that at normal temperature, the lithium battery can be charged continuously for 48 hours without accidents such as battery expansion, leakage and rupture, and the capacity is maintained at more than 95%. And under the dedicated charger, it can be charged and discharged quickly.

The production cost of lithium batteries is high, and the production equipment is expensive and labor costs account for it.

to about 40% of the production cost, ** about three times that of lead-acid batteries. Its tripling ** brings not a high cost performance. It gives people a sense of vanity and unreality, and lithium batteries are not allowed.

If it is broken, it can only be thrown away, or find a place to bury it, and after thousands of years, future generations will dig it out and it will be an antique.

All batteries with acidic aqueous solution as electrolyte are collectively referred to as acid batteries, the most typical of which is lead-acid batteries.

Lead-acid battery is eliminated, its positive electrode is lead dioxide, negative tan bridge spike is sponge lead, the electrolyte is sulfuric acid aqueous solution, the separator (separator) uses microporous rubber separator, microporous plastic separator or other materials according to different types of lead-acid batteries, and the battery shell is made of hard rubber, engineering plastics, glass fiber reinforced plastic and other materials.

Now the lead-acid battery that is common in our daily life is the electric vehicle battery.

When buying a new battery car and replacing the battery of the battery car, you must pay attention to the quality and brand of the battery. The battery is the heart of the battery car, and if the battery is good, the performance of the battery car will be good in all aspects. If you don't know how to choose a battery, a worry-free way is to choose a brand.

Choosing a high-quality new battery from a high-quality brand can not only avoid all kinds of dark pits that you don't want to encounter, but also make the battery of excellent quality and worry-free and comfortable for long-term use.

As a veteran lead-acid battery production group, Changxin battery has excellent reputation and quality, and has been praised by the market for many years. As a high-end product in lead-acid batteries, Changxin graphene series adopts a more scientific direct connection structure, an upgraded formula with higher energy density, and a higher technology content, bringing longer life, longer endurance and more stable performance.

Lead-acid battery introduction American Plant created and invented the lead-acid battery in 1859, has experienced nearly 150 years of development history, lead-acid battery book width in theory and practice, in the product variety and type, commodity electrical equipment characteristics and other fields have made great progress, whether in transportation, communications, power engineering, national defense or in ocean navigation, airlines in each economic development industry, lead-acid batteries have played a key role that can not be missing. According to the difference between the structure and main use of lead-acid batteries, the structure of lead-acid batteries is roughly divided into four categories: lead-excited acid batteries for operation; 2. Lead-acid battery for driving force; 3. Fixed immovable VRLA battery; 4. Other categories, including small and medium-sized VRLA batteries, such as lead-acid batteries for mining lamps.

The nominal voltage of a single-cell lead-acid battery is that it can be charged and discharged, and the battery can be charged. In use, 6 single-cell lead-acid batteries are often connected together to form a lead-acid battery with a tolerance of 12V. There are also 24V, 36V, 48V, etc.

Whether it is a lead-acid battery or a lithium battery electric vehicle, the first is to look at your budget, and the second is to look at your own use scenario.

The advantage of lithium battery is that it is small in size, long life, and can be recharged many times, more than friends in the rental house can disassemble the battery and take it upstairs to charge, but also environmentally friendly, but it is expensive, generally 1000 up, more than 2000 good, if it is better, the battery is more expensive than the car.

There are electric vehicles riding, it should be the use of lithium battery electric vehicles, lithium batteries in the battery overcharge, internal short circuit overheating, puncture will appear deflagration, major manufacturers in order to avoid the occurrence, the battery will also have a variety of safety protection measures, but does not mean that it is safe, so daily use and purchase must pay attention to the brand, those small workshop assembly and unknown lithium batteries must not be used.

From the safety point of view alone, lead-acid batteries are the best, followed by lithium iron phosphate, lithium manganese oxide and ternary lithium in lithium batteries.

Lead-acid batteries are large in size, relatively bulky, usually the body with strong endurance is also heavier, the development is the longest, the performance is also relatively stable, relatively cheap, short life, generally more than a year may need to be replaced, depending on their specific daily use, usually a few hundred yuan can be replaced with a new one, lead-acid batteries are mainly used in electric motorcycles, and lithium batteries are national standard electric bicycles.

Different batteries, in the same performance of electric vehicles will be hundreds to thousands of differences**. If you don't have a high budget, choose a lead-acid battery, and it will be better to leave your budget on the performance of the electric car.

As a battery, in fact, the similarity is quite high, whether it is function, use and structure, there is little difference. The fundamental difference is that lead-acid batteries use lead dioxide as the energy storage carrier, while lithium batteries use lithium as the energy storage carrier.

Lithium battery: light weight, high specific energy, but poor safety and low cost performance; Lead-acid batteries are heavy, large in size, and small in specific energy, but have good safety and high cost performance.

How to correctly distinguish between lead-acid batteries and lithium batteries:

In terms of battery capacity.

The capacity of lithium batteries is generally 8-10 amps, and the capacity of lead-acid batteries is about 20 amps.

In terms of driving kilometers.

For example, the same 48V battery, in the case of full charge, lithium battery and lead-acid battery electric vehicles can run 30-40 km, and its speed mainly depends on the size of the motor used.

Durability aspect.

1) Lithium battery has strong durability, slow consumption, more than 500 times of charging and discharging, and no memory, and the general life span is 4-5 years. Lead-acid batteries are generally charged and discharged within 400 times, have memory, and have a life span of about two years. If you use a maintenance-free lead-acid battery, it should be noted that the battery has less water loss, and there is generally no need to add distilled water in use.

2) As far as durability is concerned, the lithium battery has good vibration resistance, the battery in the fully charged state is safely fixed, the amplitude of 4mm, the frequency of vibration for 1 hour, no leakage, no battery expansion and rupture, and the open circuit voltage is normal; Good overcharge resistance, 25 degrees Celsius, fully charged battery charging for 48 hours, no leakage, no battery expansion and cracking, normal open-circuit voltage, capacity maintenance rate of more than 95%; Good resistance to high current, fully charged battery 2CA discharge for 5 minutes or 10CA discharge for 5 seconds, no conductive part fuse, no appearance deformation.
