Shares of Microvast Holdings surged over 42% on Friday premarket as it saw breakthrough in its True All-Solid-State Battery (ASSB) technology, which is anticipated to enhance the safety, energy density, and efficiency of various applications.
The company said in a press release on Thursday that its ASSB technology departs from traditional lithium-ion and semi solid-state batteries by employing a bipolar stacking architecture, allowing for higher voltage levels within a single battery cell.
"Our bipolar architecture, combined with our proprietary all-solid separator, not only simplifies battery design, but also enhances energy density and operational safety," Wenjuan Mattis, CTO of Microvast said in the release.
Microvast’s innovative technology eliminates the use of liquid electrolytes found in conventional batteries, which are limited to nominal voltages of 3.2V to 3.7V per cell.
By removing these liquid electrolytes, the ASSB can achieve voltages of dozens or higher, depending on the application, a feat not possible with liquid electrolytes as they would decompose at such high voltages.
The company’s bipolar design also reduces the number of interconnections between cells, modules, and packs. This simplification could lead to improved energy efficiency and operational safety.
