Enovix announces BrakeFlow ™ technology, additional layer of protection against battery thermal runaway while maintaining high energy density.
Enovix Corporation (“Enovix”) (Nasdaq: ENVX), the leader in the design and manufacture of next generation 3D Silicon™ Lithium-ion batteries, announced its latest advancement called BrakeFlow™ technology, an intra-cell system that significantly increases tolerance against thermal runaway from internal shorts, without compromising high energy density.
Harrold Rust, Co-Founder, President and Chief Executive Officer of Enovix, said:
When we founded Enovix in 2007, our approach to improving cell performance was unique from other advanced battery technology companies.
“Solving a big problem differently than others is inherently challenging and creates unique issues. At the same time, it avoids problems others face and enables new opportunities others can’t exploit or even imagine. Today’s announcement is a momentous day for Enovix. It’s a great example of how taking a different approach can lead to game-changing technology.”

Ashok Lahiri, Co-Founder and CTO of Enovix, said:
We believe our battery architecture is one of the most significant advancements in Li-ion battery design in decades.
“Not only does our architecture enable a 100 percent active silicon anode, which notably increases energy density, but also enables us to launch new innovations like BrakeFlow, which by design, reduces the temperature rise at a short location, adding exceptional tolerance against thermal runaway.”
Unlike conventional “jellyroll” Li-ion cell architecture, where energy density and safety can be in conflict, the Enovix 3D cell architecture incorporates multiple intra-cell features to improve electrical, physical and environmental abuse tolerance over conventional wound Li-ion cells.
In addition to BrakeFlow, the Enovix cell architecture:
- Provides better Lithium Plating Protection over graphite anode cells due to a 100% active silicon anode (140mV higher lithiation potential1)
- Enables hotspot reduction and heat dissipation due to excellent thermal conductivity (nearly 5X cell thermal conductivity compared to similar pouch cells2);
- Includes enhanced protection from physical abuse, including crush, pinch and nail penetration due to its mechanical internal constraint system; and
- Is designed to limit movement of the anode, cathode and separator due to internal “pinning,” which is a known source of internal shorting in conventional Li-ion batteries.
Cam Dales, GM and Chief Commercial Officer, said:
BrakeFlow ushers in a new level of safety in Li-ion battery design
“Adding BrakeFlow can significantly limit overheating during an internal shorting event, which is the primary cause of thermal runaway. Additionally, the mechanical robustness of our cell architecture allows customers designing for rugged environmental conditions to choose our high energy density pouch cells over lower energy density prismatic cells.”
“This is just another example of what sets us apart from other advanced Li-ion battery manufacturers.”
BrakeFlow technology will become part of the company’s automatic tooling and production set at its Fremont factory, Fab-1. The company anticipates BrakeFlow will be available in its battery cells in 2023.
