At present, major lithium battery manufacturers have designed various types of lithium battery protection chips for different types of lithium-ion battery overcharge, overdischarge, and overcurrent protection requirements to ensure battery safety performance and avoid deterioration of battery characteristics. Most of these lithium battery protection chips are suitable for lithium-ion batteries with 1-4 cells in series, and very few new products, such as Texas Instruments' BQ77PL900 chip, are suitable for lithium-ion batteries with 5-10 cells in series, and their protection functions Perfect and widely used in many lithium battery protection circuits. However, for many serial numbers, such as battery packs with more than 10 strings of lithium batteries in series or the number of protection chips are different from the actual number of lithium battery packs in series, if the current integrated circuit chips on the market are used to make the protection circuit, there will be no The disadvantage of not being flexible enough to achieve protection or use.
Low-temperature lithium-ion batteries are classified according to their discharge performance: energy storage low-temperature lithium-ion batteries, rate-type low-temperature lithium-ion batteries.
Lithium-ion batteries often have certain failure phenomena during use or storage, including capacity decay, internal resistance increase, rate performance reduction, gas production, liquid leakage, short circuit, deformation, thermal runaway, lithium evolution, etc., which seriously reduce lithium ion The performance, reliability and safety of the battery. These failure phenomena are caused by the interaction of a series of complex chemical and physical mechanisms inside the battery.
Lithium-ion battery has a high energy density, its capacity is 1.5 to 2 times that of a nickel-hydrogen battery of the same weight, and it has a very low self-discharge rate. In addition, lithium-ion batteries have almost no "memory effect" and do not contain toxic substances. These advantages of lithium-ion batteries make it widely used in the field of new energy vehicles.
Lithium-ion batteries and lead-acid batteries are currently the two most widely used batteries. So what is the difference between these two batteries and which one is better? The following will focus on the difference between lithium-ion batteries and lead-acid batteries.
