POLYIMIDE CAPACITANCE BATTERY AND MANUFACTURING METHOD THEREOF

摘要

The invention concretely relates to a polyimide capacitance battery and the manufacturing method thereof. The polyimide capacitance battery has a positive electrode, a negative electrode, a polymer membrane between the positive electrode and the negative electrode and an electrolyte, which is formed by manufacturing the positive electrode and the negative electrode and then assembling the positive and negative electrodes. The positive electrode material is a mixture of lithium ion insertion compound and porous carbon material. The negative electrode material is the mixture of modified graphite and porous active carbon material. The polymer membrane is polyimide membrane, and the electrolyte contains lithium ion compound and an organic solvent electrolyte. The polyimide capacitance battery may widely be used in many fields as electric automobile, electric tool, solar energy storage, wind energy storage, and portable appliances etc.
