The commercialization of all-solid-state battery production

The commercialization of all-solid-state battery production is a complex system engineering process, with its core mainly consisting of three key components: material system development, cell structure design, and cell production control. To produce a high-performance commercial all-solid-state battery, it is essential to master these three core aspects. Once the process for manufacturing commercial all-solid-state batteries is mastered, assembling and producing coin-type half-cells, coin-type full-cells, and simple structure flexible batteries (with a single positive/negative electrode stacked structure) becomes relatively easy.

Lithium-ion Full Battery Manufacturing Process Training

Lithium-ion Full Battery Manufacturing Process Training 1. Basic Knowlege Of Mixing Slurry mixing is the process of adding active materials, conductive carbon black, dispersants, binders, additives, and other components to a mixing equipment in a certain proportion and order. Under the mechanical actions such as turning, kneading, and shearing generated by the equipment, these components are mixed together to form a uniform, stable solid-liquid suspension system suitable for coating.The goal is to achieve uniformity and consistency on both the macro and micro levels.

Lithium-ion Full Battery Manufacturing Process Training--Coating

1. Coating Basics Purpose: To uniformly coat a fluid slurry onto the surface of a metal foil, dry it, and produce a battery electrode Principle: The coating roller rotates to carry the slurry, and the amount of slurry transferred is adjusted by adjusting the gap between the doctor blade and the roller. The relative rotation of the back roller and the coating roller is used to transfer the slurry onto the substrate. Subsequently, the solvent in the slurry is evaporated through drying and heating, causing the solid matter to adhere to the substrate.

Lithium-ion Full Cell Manufacturing Process Training--Soft-Pack Battery Formation - Part 2

1. Key Factors Influencing Formation: Mechanism Generation Process of SEI Membrane: l Electrons are transferred from the current collector, through the conductive agent, to point A inside the graphite particles where the SEI membrane is to be formed. l Solvated lithium ions, wrapped in the solvent, diffuse from the cathode to point B on the surface of the SEI membrane that is currently being formed. l The electrons at point A diffuse to point B through the electron tunneling effect. l The electrons that jump to point B react with lithium salt, solvated lithium ions, film-forming agents, etc., to continue generating the SEI membrane on the surface of the existing SEI membrane. This process results in the continuous increase of the SEI membrane thickness on the surface of the graphite particles, ultimately leading to the formation of a complete SEI membrane.
