Sodium ion battery with copper-selenium compound as negative electrode material

Abstract

The invention relates to the technical field of sodium-ion batteries, and discloses a sodium-ion battery with a copper-selenium compound as a negative electrode material, which comprises a battery andtwo electrodes connected to the battery, and protection mechanisms are symmetrically connected to one end, close to the electrodes, of the battery. The protective mechanism comprises a protective cover, a wiring hole, a supporting plate, a first threaded hole, a first threaded rod, a connecting plate, a connecting block, a baffle and a through hole; wherein the protective cover is fixedly connected to the end, close to the electrode, of the battery, the electrode is arranged in the protective cover, the wiring hole is formed in one side of the protective cover, and the supporting plate is fixedly connected to the outer wall of one side of the protective cover. According to the sodium ion battery with the copper-selenium compound as the negative electrode material, the waterproof and anti-corrosion capability of the electrode can be improved, so that the electrode is prevented from being corroded, the resistance is increased, the electric quantity waste is less, the electrode is not easy to rust and heat, the safety is higher, the wire can be pressed on the electrode, the complex wiring operation is omitted, the time and labor are saved, and the wire is more stable and is not liable to fall off.

Description

technical field [0001] The invention relates to the technical field of sodium ion batteries, in particular to a sodium ion battery in which a copper selenium compound is used as a negative electrode material. Background technique [0002] Sodium-ion battery is a secondary battery (rechargeable battery), which mainly relies on sodium ions to move between the positive and negative electrodes to work. It is similar to the working principle of lithium-ion batteries, with low cost and high energy density. The current sodium-ion battery electrodes are exposed Outside, when used in some environments, the electrode is easily corroded and rusted, the resistance of the electrode increases, the waste of electricity is serious, the heat is large, and it is easy to cause a fire accident.
