What is Semi-Solid State Battery Technology?

Semi-Solid State batteries represent a hybrid approach combining solid and liquid electrolytes, with solid materials comprising over 90% of the total structure.

Key Advantages

• Higher energy density compared to conventional lithium-ion batteries

• Superior thermal stability for enhanced safety over liquid electrolyte batteries

• Compatible with existing production lines reducing manufacturing costs

Chinese authorities are preparing new terminology standards, planning to rename "Semi-Solid State" batteries as "Solid-liquid Batteries" to clearly distinguish them from full Solid-State batteries still under development.

The MG4 continues to perform strongly in the market, with sales reaching 11,480 units in October. The Anxin Edition will be added to the lineup once mass production begins.
