Types and life of lithium-ion batteries

Lithium-ion battery is a type of battery that uses lithium metal or lithium alloy as the negative electrode material and uses a non-aqueous electrolyte solution. Types of lithium-ion batteries Lithium-ion batteries can be roughly divided into two types: lithium-ion batteries and lithium-metal batteries. Lithium-ion batteries generally use lithium alloy metal oxide as the positive electrode material, graphite as the negative electrode material, and non-aqueous electrolyte batteries, which are current mainstream batteries; lithium metal batteries generally use manganese dioxide as the positive electrode material, metal lithium or its alloy metal It is a battery that uses a non-aqueous electrolyte solution as a negative electrode material. Lithium metal batteries have higher technical requirements, but their safety, specific capacity, self-discharge rate, and performance-price ratio are better than lithium-ion batteries, and now only a few companies in a few countries produce. How long is the life of a lithium-ion battery? Most people measure the life of a lithium-ion battery by the number of times of charging and discharging. In fact, the lithium-ion battery is completely exhausted and recharged will cause more damage to the battery. Therefore, if the battery is recharged with normal power every time, the life span of the lithium-ion battery will be prolonged instead. Generally speaking, lithium-ion batteries have a lifespan of 23 years, but high-quality batteries will still retain 80% of the original capacity after multiple cycles of charging and discharging. Therefore, many lithium-ion-powered products can still be used after two or three years. use. Disclaimer: Some pictures and content of the articles published on this site are from the Internet.
