What impact the charging temperature ＜0 ℃ on the lithium-ion battery?
Li-ion battery charging in low temperature environment has certain risks. Because with the decrease of temperature, the dynamic characteristics of graphite anode become worse and worse. During the charging process, the electrochemical polarization of the anode is significantly intensified. The precipitated metal lithium is easy to form lithium dendrites, break through the diaphragm and cause the positive and negative pole short circuit. Try to prevent lithium ion batteries from charging at low temperature.
What is the charging and discharging principle of ternary lithium-ion battery?
The full name of the ternary lithium-ion battery is the ternary polymer lithium battery. The ternary polymer lithium battery refers to the lithium battery whose positive electrode material uses nickel-cobalt lithium manganate (Li(NiCoMn)O2) ternary positive electrode material. The ternary composite positive electrode material Precursor products are made of nickel salt, cobalt salt, and manganese salt. The ratio of nickel, cobalt, and manganese can be adjusted according to actual needs. The battery with ternary materials as the positive electrode is safer than lithium cobalt oxide batteries.
