Microvast Unveils Breakthrough in All-Solid-State Battery Technology

STAFFORD, Texas, January 09, 2025 – Microvast Holdings, Inc. (NASDAQ: MVST), a global leader in advanced battery technologies, announced a groundbreaking advancement in its True All-Solid-State Battery (ASSB) technology. This innovation marks a significant step forward in enhancing safety, energy density, and efficiency for applications such as data center backup power systems, electric school buses, and future robotics and electric vehicle sectors.

Unlike traditional lithium-ion or semi solid-state batteries, Microvast’s ASSB employs a bipolar stacking architecture, enabling internal series connections within a single cell. This design eliminates liquid electrolytes, allowing the battery to achieve voltages unattainable by conventional batteries, which typically operate at 3.2V to 3.7V per cell. The absence of liquid electrolytes not only enhances safety but also simplifies system architecture, improving energy efficiency and operational reliability.

Microvast’s proprietary all-solid electrolyte separator membrane, based on an advanced polyaramid separator, ensures excellent ionic conductivity, structural stability, and long-term durability. This innovation addresses one of the most critical challenges in solid-state battery technology, enabling stable high-voltage operation without compromising safety or reliability.

“Our solid-state battery innovation represents a significant leap forward in addressing real-world safety and efficiency challenges,” said Yang Wu, CEO of Microvast. “By developing a technology that eliminates liquid electrolytes and prioritizes scalability, we are well-positioned to meet the evolving needs of industries requiring reliable and safe energy storage solutions.”

The company’s ASSB technology also introduces a new frontier in customized cell design. With its flexible form factor and voltage configuration, the batteries can be tailored to meet the specific energy and spatial requirements of advanced robotic systems and other high-demand applications. “Our bipolar architecture, combined with our proprietary all-solid separator, not only simplifies battery design but also enhances energy density and operational safety,” said Dr. Wenjuan Mattis, CTO of Microvast.

Microvast’s ASSB technology has demonstrated stable operational voltage ranges between 12V and 21V during charge and discharge cycles, a feat unachievable with liquid electrolytes. The company is now advancing to the pilot production phase, aiming to overcome unique manufacturing challenges and set new industry standards for battery technology.

Founded in 2006 and headquartered in Stafford, Texas, Microvast has a 17-year legacy of delivering cutting-edge battery systems for electric vehicles and energy storage solutions. The company’s latest innovation underscores its commitment to empowering a cleaner and more sustainable future.
