Unlike conventional lithium-ion or semi solid-state batteries, Microvast’s ASSB utilizes a bipolar stacking architecture that enables internal series connections within a single battery cell. Traditional lithium-ion and semi solid-state batteries, constrained by the limitations of liquid electrolytes, typically operate at nominal voltages of 3.2V to 3.7V per cell. In contrast, Microvast’s technology completely eliminates liquid electrolytes. This breakthrough allows a single cell to achieve dozens of volts or higher based on specific application needs. A voltage unattainable by any battery containing liquid electrolytes, which would otherwise decompose under such high voltages.
This bipolar design significantly reduces the number of interconnections between cells, modules, and packs. This simplifies the overall system architecture and enhances both energy efficiency and operational safety. Furthermore, Microvast has developed its proprietary all-solid electrolyte separator membrane based on an advanced polyaramid separator, which is non-porous and tailored specifically for solid-state applications. This separator ensures excellent ionic conductivity, structural stability, and long-term durability, addressing one of the most critical technical challenges in solid-state battery technology. Moreover, the ability to maintain stable high-voltage operation without compromising safety or long-term reliability underscores a key technical advantage of Microvast’s ASSB technology, positioning it as a transformative innovation in the battery industry.
