Application: Silicon-carbon pre-lithium composite anode material and method for making the same and battery (Patent ID: US20230411598A1)
The patent filed by Hon Hai Precision Industry Co Ltd describes a method for producing a silicon-carbon pre-lithium composite anode material for batteries. The process involves nanoizing silicon materials to create nano-silicon particles, adding carbon materials and polymer to form a silicon-carbon composite, incorporating a pre-lithium nanomaterial, mixing the composite with the nanomaterial, granulating the mixture, and sintering the resulting precursor. The method aims to enhance battery performance by optimizing the composition and structure of the anode material.
Furthermore, the patent outlines specific steps and materials used in the manufacturing process, such as selecting carbon materials like pitch or graphene, utilizing protective environments during nanoizing and sintering, and controlling the mass ratio of pre-lithium nanomaterial to the silicon-carbon composite. The resulting silicon-carbon pre-lithium composite anode material consists of a composite structure with a pre-lithium nanolayer covering it, enhancing battery efficiency and stability. The patent also extends to the application of this anode material in batteries, highlighting its potential to improve overall battery performance and longevity.
