Grepow Introduces Patented Curved Battery Technology, Delivering 30% Higher Capacity for Next-Generation Smart Rings
Grepow's white paper introduces its patented E-stacking process, which enables curved cells to deliver up to 21 mAh of capacity—compared with 16 mAh in conventional cells of the same size—and to sustain over 500 stable cycles, significantly extending device lifespan. In a separate patent, the curved dual-tab battery design provides greater flexibility in industrial design, enabling the cells as narrow as 4.1 mm (typically 6 mm) and supporting slimmer, more adaptable power configurations for compact wearables. Each cell undergoes 100% X-ray and CCD inspection to ensure safety and reliability, while advanced silicon–carbon anode formulations further increase capacity and improve volumetric energy density by 17.2%.
By removing long-standing constraints in small-form-factor battery design, Grepow's patented technology enables thinner, lighter, and longer-lasting smart rings, paving the way for seamless 24/7 health monitoring, gesture control, and biometric sensing in everyday wear.
