The negative electrode of Li-SOCl2 battery is metal Li, and the internal positive active material and electrolyte solution are thionyl chloride. It has the highest specific energy and specific capacity in all chemical power sources that can be actually used. It is widely used in many modern electronic devices. Lithium thionyl chloride battery is a disposable battery and can not be charged.

The negative electrode of lithium manganese dioxide (Li MnO2) battery is metal Li, the internal positive active material is manganese dioxide, and the external packaging is made of aluminum plastic film soft package. High specific energy and good safety performance. Lithium manganese dioxide battery is a primary battery and cannot be recharged.

Supercapacitor, also known as electrochemical capacitor, is different from the traditional chemical power supply. It is a power supply with special performance between the traditional capacitor and the battery. Its energy storage process does not have chemical reaction and is reversible. Because of this, supercapacitor can be charged and discharged hundreds of thousands of times repeatedly.
