Earlier we have seen several smartphone patents from Xiaomi including a detachable rear camera, sliding screen display, pop-up camera, Tri-folding phone, and more. This time Xiaomi patented a new lithium battery technology.
Battery bulging is more than just a sign of an aging battery pack, but also a matter of safety risk. Meanwhile, this new battery technology explores to address this issue.

Going by the report, this patent is invented by Luo Wenhui. However, the Chinese tech giant applied for the patent last month but got published earlier this week. This new battery patent is titled “Battery Expansion Prompt Method and Device”.
As the name indicates, this technology will be able to detect and inform users concerning their aging battery and its health. We can also say that to avoid any complications, this technology alert the user on detecting if the battery is bulging.
Furthermore, as per the description, the present disclosure relates to a method and device for proposing battery expansion. The device includes a battery section, a battery back cover, piezoelectric ceramics, and a current detection circuit.
Whereas, at a position facing the battery, the piezoelectric ceramic is placed on the inner side of the back cover of the battery or the bottom of the battery compartment.
The current detection circuit, connected to the piezoelectric ceramic is used to detect a current signal generated by it. When the piezoelectric ceramic generates a current signal, it means that the degree of battery enlargement beats an extension origin.
Moreover, the technology would be based around the battery and it will be able to detect any irregularities in its shape. This technology could soon even be stapled in the industry, especially in terms of safety.
