The Quest for Battery Safety
The endeavor to ensure battery safety is indeed a relentless journey. With manufacturers vigorously pursuing solutions, the rarity of electric battery fires certainly doesn’t imply negligence. Enter Xiaomi, which has ingeniously tackled this concern in a novel way.

Xiaomi’s Ingenious Solution
In a stunning factory tour in Beijing, Xiaomi unveiled its creative approach to mitigating thermal runaway—the phenomenon that can lead to dangerous battery fires. The revolutionary design integrated into the Su7 features battery cells that are mounted upside down. This isn’t just a quirky design choice; the cells are specially engineered to ensure safety. With the battery pack acting as a structural element of the car, Xiaomi has maximized both aesthetics and security.
Engineering Challenges and Innovations
Flipping battery cells may sound simplistic, but Xiaomi, in collaboration with CATL, faced unique challenges. Gravity impacts the battery’s electrolyte dynamics in unpredictable ways, and corrosion risks loom over the exposed metal contacts. The solution? A specifically formulated electrolyte and the use of anti-corrosive metals. Coupled with aerogel insulation on each cell, this cutting-edge technology makes the charger less susceptible to hazardous incidents.
The Su7 stands as a testament to creativity in the EV market. While the design ensures a low-slung profile akin to traditional combustion vehicles, it is also a symbol of safety innovation. As Xiaomi prepares to introduce this technology to global markets by 2027, the future of battery safety appears brighter than ever.
