[0002] Lithium-ion batteries are divided into different systems of lithium iron phosphate, lithium cobalt oxide, lithium manganese oxide, cobalt-manganese mixture, and ternary materials. The outer shells are divided into steel shells and polymers. Batteries of different material systems have different advantages. At present, lithium-ion batteries for electronic cigarettes are mainly single-material system batteries. Lithium cobalt oxide and ternary material batteries have high capacity, high output voltage, good charge and discharge cycle performance, stable output voltage, large current discharge, electrochemical stability, wide operating temperature range, and environmental friendliness.

[0003] Nickel-metal hydride and nickel-cadmium are widely used as 1.2V / 1.5V dry batteries in the market. However, their disposable characteristics are widely controversial. As environmental protection issues become increasingly prominent, 1.2V / 1.5V rechargeable lithium batteries are becoming more and more popular. However, their non-removable and high cost problems have become pain points for consumers. Therefore, the utility model proposes a removable lithium-ion battery. Utility Model Content
