Abstract:

All-solid-state lithium batteries, with good safety, long life and high energy, are an emerging option for next-generation technologies on the road to a green energy storage device. All-solid-state lithium batteries are prepared with all-solid electrode and all-solid electrolyte without liquid additives. Therefore, the electrode preparation and assembly of all solid-state lithium batteries are quite different from those of existing liquid lithium batteries. Here we summarize the typical assembly approaches of prototype all-solid-state batteries using oxide, sulfide, or polymer as solid electrolytes, providing reference for all-solid-state battery researchers.In this paper, the electrode preparation and assembly technology with the corresponding performance characteristics of several typical all-solid-state lithium batteries are reviewed in detail. The structure, cathode preparation methods, anode modification methods and battery assembly methods of oxide, sulfide and polymer solid electrolyte are summarized and analyzed respectively. Finally, some suggestions on the laboratory development and assembly methods of all solid state lithium batteries are given.

Key words: all-solid-state lithium batteries, electrodes preparation, assembly technology, solid electrolyte, lithium batteries
