Semi-solid Battery
Semi-solid state battery is a new type of energy storage technology between traditional liquid lithium batteries and all-solid state batteries , the electrolyte part of which consists of gel-like or solid-liquid hybrid electrolyte materials . It maintains the safety characteristics of solid-state batteries, but also has the high energy density and processing compatibility of liquid batteries.Its electrolyte is solid-liquid mixed state (liquid electrolyte accounted for 5-15%), both high energy density (300-450Wh/kg) and high safety (pinpoint resistance, resistance to thermal runaway).

Active materials, conductive agents, and binders are uniformly dispersed in solvent to form electrode slurry.
Homogenized slurry is coated onto aluminum foil and dried to form electrode sheets.
Coated electrodes are compressed to specified thickness under controlled pressure.
Post-calendering electrodes undergo vacuum drying to remove residual moisture.
Electrode sheets are precision-cut to required dimensions.
Anodes, cathodes, and separators are stacked in “Z” configuration to form cell cores.
Multi-layer electrode tabs are aligned, ultrasonic-welded, and insulated with adhesive tape.
Cell cores are housed in pre-formed aluminum laminate pouches with top/seal side sealing.
