Microvast Holdings, a Texas-based battery manufacturer, has announced the development of its new True all-solid-state battery (ASSB), which eliminates liquid electrolytes to achieve high voltages between 12 V and 21 V. The innovative design also incorporates a bipolar stacking approach, reducing the need for interconnections between cells, modules, and packs.
Traditional lithium-ion and semi-solid-state batteries, which rely on liquid electrolytes, typically operate at nominal voltages of 3.2 V to 3.7 V per cell. Microvast’s new technology, however, completely removes liquid electrolytes, allowing for stable high-voltage operation without sacrificing safety or long-term reliability. The ASSB’s bipolar stacking design ensures that individual cells can reach higher voltages without decomposing, a challenge that has previously limited high-voltage performance in similar systems.
This breakthrough could be a significant step forward in advancing the adoption of solid-state batteries for various applications, including electric vehicles and energy storage.
