What is a lithium battery?

Lithium battery is a type of battery that uses lithium ions to move back and forth between the positive and negative electrodes to store and release electrical energy. Lithium batteries typically consist of a positive electrode, negative electrode, electrolyte, and separator. Among them, the positive electrode usually uses compounds such as lithium cobalt oxide, lithium iron phosphate, or lithium nickel cobalt manganese oxide. The negative electrode usually uses materials such as graphite or silicon, and the electrolyte usually uses organic solutions or polymer electrolytes. Lithium batteries have advantages such as high energy density, long service life, low self discharge rate, and environmental protection, and are widely used in electronic products, electric vehicles, energy storage, and other fields. However, there are also some issues with lithium batteries, such as overcharging, discharging, short circuits, high temperatures, etc., which can lead to battery combustion or explosion. Therefore, corresponding safety measures need to be taken to protect the safe use of lithium batteries.
