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.

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.

Nickel Cobalt Manganese(NCM)

Ternary lithium battery classification Ternary lithium batteries, that is, lithium batteries that use nickel cobalt manganese oxide ( NCM ) or nickel cobalt aluminum oxide (NCA) as the positive electrode material, have various classification methods according to different classification standards.
