A lithium metal electrode sheet processing method and apparatus, and a battery. The lithium metal electrode sheet processing method comprises: acquiring a lithium metal sheet; and performing laser cutting on the lithium metal sheet at a first speed and a first laser power, so as to acquire a cut lithium metal electrode sheet, wherein the first speed is within a range of 1 to 200 m/min, the first laser power is within a range of 1 to 200 W, and the height of a burr generated at a cut edge of the cut lithium metal electrode sheet is less than 50 μm.
A method and device for compositing a battery electrode sheet and a separator, a battery cell preparation method, and a battery. The method for compositing a battery electrode sheet and a separator comprises: respectively obtaining a positive electrode sheet, a lithium metal negative electrode sheet, a first separator, and a second separator; and compositing the positive electrode sheet, the lithium metal negative electrode sheet, the first separator, and the second separator at the same time to obtain a composite electrode sheet. In the composite electrode sheet, the first separator is formed between the positive electrode sheet and the lithium metal negative electrode sheet, and the lithium metal negative electrode sheet is formed between the first separator and the second separator.
The present invention relates to materials and methods for components of zinc-ion batteries, such as manganese oxide cathodes having a coating. The coating comprises an oxide compound, a nitride compound, a fluoride compound, a phosphate compound, a sulfide compound, or any combination thereof.

Environmentally preferable method of making solid electrolyte and integration of metal anodes thereof
+ conducting electrolyte thin films. Methods are also provided for using the solid electrolyte particles and/or thin films in manufacturing safer and more efficient lithium-based batteries. In particular, the method uses inorganic precursors instead of using organic precursors in preparing an aerosol and then convert the aerosol to solid powders to provide the solid electrolyte particles. The solid electrolyte particles prepared have a cubic polymorph and have a desired particle size range, and are capable of making a solid electrolyte film with a thickness less than 50 μm.
