What is a lithium battery

　　A lithium battery is a type of battery that uses lithium metal or lithium alloy as the negative electrode material and a non-aqueous electrolyte solution. It mainly relies on the movement of lithium ions between the positive and negative electrodes to achieve the charging and discharging process.

　　Lithium batteries have the following characteristics:

　　High energy density: capable of storing a large amount of electrical energy, it can provide longer range or usage time than other types of batteries under the same volume or weight, which makes it widely used in portable electronic devices, electric vehicles and other fields.

　　Long cycle life: Generally, it can be charged and discharged hundreds or even thousands of times, and compared to some traditional batteries, it has a longer service life.

　　Low self discharge rate: When not in use, the loss of self power is relatively slow, which can maintain the power well.

　　No memory effect: It can be charged at any time without the need to fully discharge and recharge like some traditional batteries, making it more convenient to use.
