In recent years, various new varieties have been studied at home and abroad. Among them, there are the following 5 types of prominent new lithium batteries.

　　1. Secondary battery that does not use lithium metal

　　The secondary battery that does not use metal lithium uses an embedded lithium material as the negative electrode, which is also called a lithium-ion negative electrode, and the positive electrode combined with the intercalation compound constitutes a lithium-ion battery. During charging and discharging, lithium ions are reversibly inserted and extracted between the positive and negative electrodes. Because there is no metal lithium, the cycle performance and safety performance of the battery have been improved.

　　2. Digital Lithium Ion Battery

　　Digital lithium-ion battery has high voltage, high specific energy, long cycle life, short charging time, abundant raw materials and safe use.

　　3. Polymer lithium battery

　　Li-polymer batteries use polymer materials as the positive electrode and lithium metal as the negative electrode, which can be made into higher energy and greater density. In terms of structure, it can be thinned, the thickness is about 2~4mm, the minimum thickness is 0.5mm, and it can be made into any shape and capacity, and its weight, energy, and density are 50% higher than current lithium electronic batteries. % Or more, in terms of reliability characteristics, because the electrolyte also uses polymer materials, there will be no safety concerns such as liquid leakage, combustion and explosion.
