Microvast Holdings, Inc., a Texas-based battery technology company, has introduced its innovative True All-Solid-State Battery (ASSB) technology, promising to enhance battery safety, energy density, and operational efficiency. The new battery is designed for a range of industries, including electric vehicles (EVs), robotics, and energy storage, offering safer high-voltage operation in a compact form factor.
The standout feature of the ASSB is its bipolar stacking architecture. Unlike traditional lithium-ion batteries that rely on liquid electrolytes, the solid-state design eliminates the liquid component, allowing for higher voltage operation and increased safety. The battery integrates internal series connections within a single cell, streamlining system design while improving energy efficiency. The solid electrolyte separator membrane, made from advanced polyaramid, offers exceptional ionic conductivity and long-term durability.
In performance testing, the ASSB demonstrated a stable voltage range between 12V and 21V, surpassing the capabilities of conventional battery designs. This makes the ASSB well-suited for high-energy-density applications while maintaining safety standards.
For electric vehicles, the new ASSB technology could significantly enhance performance and reliability. By removing liquid electrolytes, the battery can support safer high-voltage operations and enable smaller, lighter battery packs without compromising energy output. The compact design promises to increase the range of EVs while reducing charging times, all while minimizing risks related to thermal runaway. Additionally, the flexibility of the ASSB technology allows for customized form factors, providing EV manufacturers with the opportunity to design more efficient and space-saving battery layouts, potentially reducing production costs and making electric vehicles more affordable for a wider audience.
