Battery manufacturer Grepow has announced a breakthrough in a wearable battery design . They have discovered a silicon-carbon anode battery tech that’s built specifically for the smart rings. Per the claims, this new tech can deliver higher capacity, improved safety, and longer life, all while keeping the form factor incredibly thin.
The next-gen battery tech for smart rings brings revolutionary design and improved performance
Until now, most smart rings, such as the Samsung Galaxy Ring or the Oura Ring , have employed traditional lithium-polymer (LiPo) batteries. The newly discovered silicon-anode battery tech brings a significantly enhanced battery density, without expanding the size. And as a result, it is capable of providing up to 30% more battery capacity in a similar to even less space. This is a major win for compact wearables.
The company also adds that it has ditched the typical “winding” production method for a new E-stacking process. In the new process, the layers are precisely stacked and heat-formed into an arc shape. It allows for a more uniform internal structure, reducing mechanical stress and improving battery efficiency.
Grepow says the new tech is smarter, efficient, and reliable
Grepow further claims that the new stacking process allows its micro-batteries to last around 500 charging cycles. This is a huge leap when compared with the traditional 200-300 charging cycles assured for LiPo cells. Another standout aspect of the discovery is its safety and versatility. The company’s white paper highlights that its stacked silicon-anode cells can be as thin as 1mm and only 4.1mm wide, while maintaining 80% better safety performance compared to standard ring batteries.
The company has not yet announced when manufacturers can start testing the new battery tech . But we can expect major brands such as Samsung and Oura to adopt the tech in the next few generations of smart wearables .
