A lithium-ion battery or Li-ion battery (abbreviated as LIB) is a type of rechargeable battery in which lithium ions move from the negative electrode to the positive electrode during discharge and back when charging. Li-ion batteries use an intercalated lithium compound as one electrode material, compared to the metallic lithium used in a non-rechargeable lithium battery. The electrolyte, which allows for ionic movement, and the two electrodes are the constituent components of a lithium-ion battery cell.
FAQ of Lithium Battery
1, the secondary battery performance mainly includes what aspects
Mainly include voltage, internal resistance, capacity, internal pressure, self-discharge rate, cycle life, sealing performance, safety performance, storage performance, appearance and so on, other overcharge, over discharge, weldability, corrosion resistance and so on.
2, the comparison of rechargeable batteries and alkaline batteries:
In most cases, nickel-metal hydride batteries can completely replace disposable batteries, especially when used in high-power equipment.
Although alkaline batteries have a rated voltage of 1.5 volts, the voltage drops continuously after the discharge starts. Looking at the entire discharge process, the average alkaline battery voltage is about 1.2 volts, and very close to the nickel-metal hydride batteries, the main difference is that the alkaline battery voltage at the start of 1.5 volts, and eventually dropped to less than 1.0 volts, and nickel-metal hydride batteries It will maintain a voltage of about 1.2 volts most of the time.
