Abstract:

The semi-solid energy storage batteries combine the advantages of high energy density of rechargeable batteries with the flexible design of flow batteries.It is a new type of electrochemical energy storage technology that has attracted widespread at-tention.The research progress on semi-solid batteries in the fields of lithium-ion batteries,lithium-sulfur batteries,zinc batter-ies,air batteries,organic batteries and other different types of energy storage batteries were reviewed.And the influence of active materials,conductive additives,electrolytes in the semi-solid electrodes and battery structure on the performance of semi-solid batteries were explored.Then problems in the development of semi-solid electrodes were further analyzed and sum-marized,and it was found that the performance of semi-solid batteries could be effectively improved by developing new mate-rials and new chemical systems.Finally,it was put forward that the research focus of semi-solid batteries in the future was to improve energy density and cycle stability,and reduce slurry viscosity,etc.

Key words: energy storage batteries, semi-solid electrodes, flowable batteries, new system
