Microvast, a U.S.-based battery technology company, has made significant progress in developing its all-solid-state battery (ASSB) technology. Unlike traditional lithium-ion batteries that rely on liquid electrolytes, Microvast's ASSB uses a bipolar stacking architecture and a proprietary solid-state electrolyte membrane. This design eliminates safety risks and energy density limitations associated with liquid electrolytes.
The ASSB technology enables individual battery cells to achieve significantly higher voltages, simplifying the overall system architecture. Traditional lithium-ion and semi-solid batteries typically have nominal voltages between 3.2V and 3.7V per cell. In contrast, Microvast's ASSB technology can deliver tens of volts or more per cell, depending on specific application requirements.
This increased voltage capability is achieved by eliminating liquid electrolytes and using Microvast's proprietary solid-state membrane. The membrane is based on an advanced polyaramid material, designed specifically for solid-state applications. It ensures excellent ionic conductivity, structural stability, and long-term durability, addressing one of the critical challenges in solid-state battery technology.
The bipolar design also simplifies the overall battery system. It significantly reduces the number of interconnections between cells, modules, and battery packs, enhancing energy efficiency and operational safety. Microvast claims that its solid-state batteries can be customized to meet specific energy and space requirements for various applications, particularly in electric vehicles, advanced robotic systems, and AI-driven technologies.
