An ionic conductor slurry comprised parts by mass: 0.05 wt %-99.98 wt % of an ionic conductor powder material, 0 wt %-2 wt % of an anti-settling agent, 0 wt %-10 wt % of a binder, 0 wt %-2 wt % of dispersant, 0 wt %-2 wt % of an auxiliary agent, and 20 wt %-99.95 wt % of a solvent, wherein the ionic conductor powder material comprises one among the following: a garnet-type solid electrolyte material, a NASICON-type solid electrolyte material, a LISICON-type solid electrolyte material, a perovskite-type solid electrolyte material, and derivatives thereof; The particle size of the ionic conductor powder is between 1 nm to 100 μm; and the ionic conductor slurry is used for separator coating material, positive electrode material coating materials, negative electrode material cladding materials, positive electrode material additive, a negative electrode material additive, polymer solid electrolyte additives, or solid-liquid mixed solid electrolyte.

Ionic conductor slurry, preparation method therefor and application thereof

A pre-lithiated film and a preparation method therefor and an application thereof. The pre-lithiated film comprises: a 1 μm-50 μm base film and a 0.02 μm-100 μm pre-lithiated coating coated on the base film; the pre-lithiated coating includes: 1 wt %-99.99 wt % of a pre-lithiated material, 0 wt %-98.99 wt % of a coating material, 0.01 wt %-10 wt % of a binder, 0 wt %-10 wt % of a conductive additive material, 0 wt %-2 wt % of a dispersing agent and 0 wt %-2 wt % of an aid. The pre-lithiated material is a material that can produce an electrochemical reaction to release lithium ions under voltage control. The pre-lithiated material specifically includes: LiM1A, LiM2(PO), LiM2(SiO), LiS, and LiM1S, wherein x, y and z are integers or non-integers and satisfy the balance of electrovalence of a chemical formula; M1 is one or a combination of a metallic element, a transition metal element, a rare earth element, an alkali metal, an IVA group element; Mis one or a combination of a metal element, a transition metal element, a rare earth element, an alkali metal, and an IVA group element; and A is one or a combination of O, F, Cl, S and N elements.

Pre-lithiated film and preparation method therefor and application thereof

The invention relates to a silicon-based anode material for a lithium-ion battery, a preparation method therefor, and a battery. The silicon-based negative electrode material is prepared by the compounding of 90 wt %-99.9 wt % of a silicon-based material and 0.1 wt %-10 wt % of carbon nanotubes and/or carbon nanofibers which grow on the surface of the silicon-based material in situ.
