Abstract

The invention discloses a lithium ion battery. The lithium ion battery comprises a lithium ion battery, and a conductive member opposite to the lithium ion battery; the lithium ion battery rubs against the conductive member under the action of an external force, so that electrical signals can be generated. The lithium ion battery of the invention has the advantages of simple structure, simple manufacture and low cost. The self-charging of the lithium ion battery can be realized.

Description

technical field [0001] The invention relates to a self-charging lithium-ion battery based on a frictional nanogenerator, which realizes the purpose of self-charging of the lithium-ion battery. Background technique [0002] In recent years, clean energy has become a focus of global attention. Researchers have developed nanogenerators that utilize clean energy such as mechanical energy, vibration energy, wind energy, and tidal energy. At the same time, energy storage is also an issue that must be considered. At present, most of the researched nanogenerators realize the separation of power generation and energy storage, mainly using nanogenerators to generate electricity, and then store the energy in batteries or capacitors in external circuits to achieve the purpose of energy storage. For example, Shuhua wang and others have designed a nano-friction generator with a fixed vibrating membrane at both ends to collect wind energy. The output signal of the generator is transformed...
