Lithium titanate battery is a kind of negative electrode material for lithium ion battery - lithium titanate, which can form 2.4V or 1.9V lithium ion secondary battery with positive electrode materials such as lithium manganate, ternary material or lithium iron phosphate. In addition, it can also be used as a positive electrode to form a 1.5V lithium secondary battery with a metal lithium or lithium alloy negative electrode. Due to the high safety, high stability, long life and green environmental protection characteristics of lithium titanate. It is foreseeable that lithium titanate material will become the negative electrode material of a new generation of lithium ion batteries in 2-3 years and be widely used in new energy vehicles, electric motorcycles and those requiring high safety, high stability and long cycle. field of application. The working voltage of lithium titanate battery is 2.4V, the highest voltage is 3.0V, and the charging current is greater than 2C (that is, the current that is twice the battery capacity value).
