Full solid battery is divided into polymer, sulfide and oxide, and is currently under laboratory research. There are certain difficulties in mass production. The fastest mass production is still semi-solid battery, and the principle is to divide the liquid electrolyte into two parts. One part of the electrolyte is added with a monomer compound in the original base liquid electrolyte, and the other part of the electrolyte is added with an initiator in the original base liquid electrolyte. Under high temperature, a solid gel electrolyte is formed by initiating polymerization, so as to realize the solidification of electrode sheet form.

[0004] The existing mass-produced solid state battery is mainly semi-solid battery, which is mixed by two kinds of electrolytes (containing monomer and initiator respectively) and realizes in-situ polymerization to form gel state under the action of high temperature. The current two kinds of electrolytes are stored, stored, transported and applied downstream by two kinds of electrolyte tanks. For battery manufacturers, the factory design is designed according to one kind of electrolyte pipeline. At present, two kinds of electrolytes are used, which only support small-scale production line modification, and small-batch battery samples are mixed online. At present, it is not possible to verify the mass production. If mass production is involved, production line and factory engineering modification are involved. The cost and cycle of modification are large, and the feasibility needs to be redesigned and planned according to the layout of each factory.

[0005] At present, the supporting supply chain of solid state battery is not perfect in the initial stage of industrialization, including raw material electrolyte supporting facilities and battery manufacturer equipment. For most battery manufacturers now, the single electrolyte of traditional liquid battery is switched to two kinds of electrolytes of solid state battery or three or four kinds or more kinds of electrolytes in the future. The production line does not have the function of multi-electrolyte injection, and the modification of pipeline and gas path is involved. The modification cycle, cost and space are large. Therefore, a solid state battery electrolyte storage device is provided. UTILITY MODEL CONTENTS
