Semi-solid-state batteries are a battery technology between liquid electrolyte batteries and all-solid-state batteries. In a semi-solid battery, the electrolyte is usually semi-solid or gel-like rather than liquid or completely solid. This design structure combines some of the advantages of liquid batteries and all-solid-state batteries to balance performance, safety and manufacturing costs.
Some features and benefits of semi-solid-state batteries include:
Safety and flexibility: Semi-solid batteries are generally safer than liquid electrolyte batteries because they avoid some of the safety issues that liquid electrolytes can cause. At the same time, compared with all-solid-state batteries, the manufacturing process and performance of semi-solid-state batteries may be more flexible and easier to implement.
Higher energy density: Semi-solid batteries generally have higher energy density than liquid electrolyte batteries, which allows them to store more electrical energy in the same volume.
Relatively low manufacturing costs: Compared to all-solid-state batteries, semi-solid-state batteries can be relatively cheap to manufacture because they generally do not require extreme manufacturing processes.
Improved stability: Semi-solid electrolytes can improve the stability of the battery to a certain extent and reduce chemical changes during charge and discharge cycles.
Semi-solid-state batteries are still in the ongoing research and development stage, so some specific technical implementations and performance characteristics may vary depending on research directions and teams. Progress in this field is expected to bring more innovations to battery technology to meet the needs of different application fields.
