Lithium Battery Knowledge

The liquid lithium battery is mainly composed of four major parts: positive electrode material, negative electrode material, diaphragm, and electrolyte. The electrolyte is mainly responsible for conducting conductive ions between the positive and negative electrodes, which affects the energy density, cycle life, power density, and safety performance of the battery. , wide temperature applications, etc. will play a key role, known as the "blood of the battery".

Ternary lithium battery (ternary polymer lithium ion battery) refers to a lithium battery in which the positive electrode material of the battery uses nickel cobalt lithium manganate or nickel cobalt lithium aluminate ternary battery positive electrode material. The ternary composite positive electrode material is a nickel salt , cobalt salt, manganese salt as raw materials, the proportion of nickel, cobalt and manganese in it can be adjusted according to specific needs, ternary materials are mainly used for new energy vehicles, electric vehicles, pneumatic tools, energy storage, intelligent intelligent sweepers, drones , intelligent smart wearable devices and other fields.

Ternary lithium-ion batteries have excellent electrochemical properties such as high energy density, good safety and stability, support for high-rate discharge, and moderate cost advantages. The battery field has been widely used.

Low temperature lithium battery, a type of lithium metal battery, has an operating temperature of -20°C to 60°C. It can work normally at low temperature, but the charging and discharging efficiency is low. It has the advantages of small size, high specific energy, good cycle performance and low cost.

The BMS battery management system is simply the steward of the battery, which plays important functions such as ensuring safety, extending the service life, and estimating the remaining power. , reduce the loss caused by battery damage.

As one of the current battery types for electric vehicles, LiFePO4 batteries are characterized by relatively stable thermal stability, low production costs, and long service life. However, its low temperature resistance is very low. In the case of -10 ℃, although the battery can be used normally, the charging efficiency will be greatly reduced.

Lithium-ion batteries have the advantages of high energy density, long cycle life, low self-discharge rate, no memory effect, green environmental protection, etc., and have broad application prospects in the field of energy storage. At present, lithium-ion battery technology mainly includes lithium cobalt oxide, lithium manganate, lithium iron phosphate, lithium titanate and other different types. From the perspective of market application prospects and technology maturity, lithium iron phosphate batteries are recommended as the first choice in the field of energy storage.

With the development of lithium battery technology, there are more and more types of cylindrical lithium batteries. Cylindrical lithium ion batteries are divided into lithium cobalt oxide, lithium manganate, and ternary materials. The three material system batteries have different advantages. Let's take a look at the models and specifications of cylindrical lithium batteries.

What is the real lifespan of a LiFePO4 battery pack? In fact, the lifespan of lithium battery packs is similar. Whether it is a LiFePO4 battery or a ternary lithium battery, the actual service life is related to the user's usage and protection. In this article, how long is the real life of a LiFePO4 battery pack?

The full name of vanadium battery is all-vanadium redox flow battery. In order to ensure the safety of energy storage power stations, the National Energy Administration issued relevant documents in June 2022. It is planned to stipulate that medium and large electrochemical energy storage power stations shall not use ternary lithium batteries, sodium Sulfur batteries, soliciting opinions from the society, let vanadium batteries usher in the spring.
