Description

technical field

[0001] The invention belongs to the field of ion batteries and their preparation, and relates to the preparation technology of novel aluminum ion batteries, in particular to WS 2 A cathode material mixed with a conductive agent and a binder and a method for preparing the entire battery. technical background

[0002] In recent years, with the continuous reduction of non-renewable energy sources such as oil, coal, and natural gas, and the huge environmental pressure and greenhouse effect brought about by their use, the development and utilization of clean renewable energy has become a current research hotspot. Among them, electric energy has become a key factor in the development and utilization of renewable and clean energy because it is at the core stage of various energy conversions. For example, currently existing tidal power generation, hydropower generation, wind power generation, solar power generation, etc. are all formed in the form of electric energy...
