In order to standardize the use of terminology in the new energy battery industry and avoid confusion between the concepts of "semi-solid state batteries" and "all solid state batteries" in the market, relevant regulatory authorities are preparing to introduce new policies to uniformly rename "semi-solid state batteries" as "solid-liquid batteries".
The naming adjustment aims to more accurately reflect the technical characteristics of such batteries, enhance industry transparency, and guide the public and investors to correctly understand the differences between different technological routes.
| Comparative Dimension | Solid Liquid Battery (Formerly Semi-Solid State Battery) | All-Solid-State Battery |
| Electrolyte State | Containing liquid or gelled components, not completely solid | Completely composed of solid electrolyte, without liquid phase |
| Ionic Conduction Mode | Mixed conduction (solid-liquid synergy) | Conducted entirely through solid-state media |
| Safety | Compared to liquid batteries, there is an improvement, but there is still a risk of combustion | In theory, it is higher, non flammable, and has strong resistance to short circuits |
| Cycle Life | Higher than traditional batteries, but lower than ideal all solid state batteries | Higher potential, still in the verification stage |
| Production Process | Compatible with some existing production lines, easy to industrialize | Complex process, difficult mass production, and high cost |
| Current Progress | Small batch loading application has been implemented | In the transitional stage from laboratory to pilot testing |
As all solid state battery technology gradually moves from the laboratory to production line verification, it is increasingly important to clarify the boundaries of the technological path. The new name "solid-liquid battery" will more scientifically reflect its technological essence and promote the healthy and orderly development of the industry. In the future, solid-liquid batteries can serve as an important technological solution for transitioning to all solid state batteries, while true all solid state batteries still need to achieve breakthroughs in materials, processes, and costs.
