The tab is a raw material for lithium-ion polymer battery products. For example, mobile phone batteries, Bluetooth batteries, laptop batteries, etc. used in our lives all need to use tabs.
In the winter, the cruising range of electric vehicles is much less than that indicated by the manufacturer, and some even reach more than one-third. Why is this?
Lithium battery separator is one of the key inner layer components of lithium battery. The performance of the separator determines the interface structure and internal resistance of the battery, which directly affects the capacity, cycle and safety performance of the battery. The separator with excellent performance plays an important role in improving the overall performance of the battery.
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.
