▎ 摘  要

NOVELTY - The battery has a negative plate and a positive plate. A sheet-shaped solid electrolyte is arranged between the positive plate and the negative plate. The negative plate is provided with a silicon carbon material. The positive plate is formed with a positive material and a solid electrolytically mixed with the positive material uniformly. The solid electrolyts are arranged in the positive and negative pole pieces and are used to bind the positive pole pieces to the silicon carbon materials to form a whole. The solenoid is a gel-solid electrolyte of the PVDF system. USE - Silicon-carbon solid battery. ADVANTAGE - The solid electrolyte has excellent net-like structure, which effectively inhibits the expansion of silicon carbon material, relieves the silicon carbon expansion caused by battery diving, and has adhesive effect, which can improve the solid content of the silicon-carbon system. The design of the battery prolongs the cycle performance of the material, expands the application market of the materials, has the capability of liquid electrolyte ion, and can quickly help the ion in and out of the carbon material. The gel electrolyte sheet is located between the positive plate and the negative plate, thus effectively binding the material and relieving the deformation in the circulation process, and hence effectively improving the depowder phenomenon, so as to improve the circulation performance and safety performance. The electrolyte layer properly reduces the thickness under the precondition of completely blocking the anode and
