Lithium Ion Battery: It is a secondary battery (rechargeable battery) that mainly relies on lithium ions moving between the positive and negative electrodes to work. During charging and discharging, Li+ intercalates and deintercalates between the two electrodes: when charging, Li+ is deintercalated from the positive electrode, and the electrolyte is embedded in the negative electrode, and the negative electrode is in a lithium-rich state;
Lithium-ion batteries are easily confused with the following two types of batteries:
(1) Lithium battery: Metal lithium is used as a negative electrode.
(2) Lithium-ion battery: A non-aqueous liquid organic electrolyte is used.
(3) Lithium ion polymer battery: a polymer is used to gel a liquid organic solvent, or an all-solid electrolyte is directly used. Lithium-ion batteries generally use a graphite-based carbon material as a negative electrode.
Lithium-ion batteries have high energy density and high average output voltage. Self-discharge is small, good battery, less than 2% per month (recoverable). There is no memory effect. The operating temperature range is -20 ° C ~ 60 ° C wide. Excellent cycle performance, fast charge and discharge, charging efficiency up to 100%, and high output power. long lasting. It does not contain toxic or hazardous substances and is called a green battery.
