Problems solved by technology

This design is relatively traditional. Since stainless steel mesh is used as the current collector, its resistance is high, the power is low, and steel mesh burrs are prone to occur, so thicker diaphragm paper is required to cooperate.

Abstract

The invention discloses a bipolar zinc ion battery, which includes at least one unit group. The unit group includes at least one battery unit. The battery unit includes: an anode plastic current collector, an isolation film, and a cathode plastic current collector which are successively stacked and attached and sealed to each other, and a cathode active material layer as a cathode disposed insidethe cathode current collector, an anode active material layer as an anode disposed inside the anode current collector, and an electrolyte in the gaps of the cathode, anode, and the isolation film andcontaining a zinc compound and a porous ion channel disposed on the isolation film between the anode and the anode for the movement of zinc ions. The bipolar zinc ion battery has simple structure andlight weight, and has good safety performance and use performance.

Description

technical field [0001] The invention relates to batteries, in particular to a plastic current collector bipolar zinc ion battery. Background technique [0002] The large-scale application of fossil fuels gave birth to great prosperity throughout the 20th and 21st centuries, but it also led to excessive emissions of greenhouse gases, which in turn led to global warming; the development of new energy is based on this background. The large-scale development and application of wind energy, solar energy, etc. have further reduced the price of new energy, and there is no cost barrier for large-scale promotion. However, the instability of its output has an impact on the power grid, and has also led to a lot of abandonment of wind and light. event. Unstable new energy requires energy stabilizers and energy mixers, and batteries are the most ideal energy stabilizers and mixers. [0003] However, conventional lithium-ion batteries are expensive and require a lot of redundancy in saf...
