Affects battery performance and causes security issues.
1. Super-welded copper foil causes problems such as short circuit and overheating inside the battery, affecting its performance and lifespan.
2. Super-welded copper foil causes battery leaks, explosions, fires and other serious safety problems, posing a threat to personal safety.
The role and use of copper in ferric phosphate
The role of copper foil in the computer room is tothe electromagneticand anti-static shielding, conducts electricity A copper foil is placed on the surface of the substrate and combined with the metal substrate, it has excellent conductivity and provides an electromagnetic shielding effect.
Copper foil has low surface oxygen properties and can be attached to dvarious substrates, such as metals, insulating materials, etc., and has a wide temperature range.
Copper foil is a cathodic electrolytic material. It is a thin, continuous metal sheet deposited on the base layer of the printed circuit board. It serves as a conductor for the PCB and bonds easily to the insulating layer. , accepts the printed protective layer and forms a circuit pattern after corrosion. It is an important material in the manufacture of copper-plated laminates and printed circuit boards.
The advantages of copper foil are to significantly improve the consistency of battery usage, significantly reduce battery costs, improve the adhesion of cathode materials and collectors using water-based systems, and to improve cathodes at the nanometric or submicron scale. The adhesion between the material and the collector is improved, the adhesion between the lith titanateium or other high-capacity negative electrode materials and the collector is improved, the qualification rate of the pole piece is improved, and the manufacturing cost of the pole piece is reduced. .
The role of copper in iron phosphate is to ensure the stability of the current collector inside the battery and is used in lithium iron phosphate batteries. For lithium-ion batteries, the commonly used positive electrode current collector is aluminum foil and the negative electrode current collector is copper foil. In order to ensure the stability of the current collector inside the battery, the purity of both must be higher. 98%. Copper is a metallic element and a transition element. The chemical symbol is Cu, English copper, and the atomic number is 29. When the surface is first cut, it is red-orange with a metallic sheen. the simple substanceis purple red and ductile. Good thermal and electrical conductivity.
