LSO (Lithium Polysilicate) Aqueous Dispersion as Inorganic Battery Electrode Binder, 200 g/bottle, CIBEBLSO

Lithium polysilicate is an inorganic aqueous binder used primarily for high-capacity battery anodes, such as those made from silicon or tin-alloys. Unlike traditional organic binders (like PVDF), it is water-based and forms a rigid, glass-like network that is exceptionally stable at high voltages and temperatures. Lithium polysilicate is a "multifunctional" binder that does more than just hold the electrode together: (1) Lithium polysilicate forms a strong, non-swelling 3D framework that maintains electrical contact between silicon particles, preventing the electrode from crumbling (pulverization). (2) Because it contains lithium ions within its silicate structure, it can contribute to lower interfacial resistance compared to insulating organic polymers. This helps improve the "rate capability" or charging speed of the battery. (3) It has a natural chemical affinity for the oxide layers on copper current collectors and silicon particles. This creates a much stronger bond than standard binders, reducing the risk of the electrode peeling off.
