In pursuit of more energy-dense small batteries, Nuvola battery design engineers have developed a folded electrode architecture that is a game changer in energy capacity for small form factor rechargeable batteries. The innovative Nimbus Z-Fold Electrode Architecture is a structural update to traditional "space-hungry" coiled electrodes used in small batteries targeted at TWS, hearing aid, wireless IoT sensors, and other demanding battery-life critical wireless applications.

When Nimbus ZEA is used to replace
coiled electrodes
Internal Space Improvement = 25% More Active Battery Material
The new Nimbus ZEA electrode architecture solves the inherent wasted internal battery space issue associated with today's popular coiled electrode designs. The Nimbus architecture uses space-efficient stacked electrodes similar to those found in EV batteries and typical high-energy cell phone batteries. Improved space utilization gives small battery designers a 20% to 25% boost in usable energy capacity compared to coiled electrode designs.
Flat Nimbus ZEA Electrodes = An Additional 25% Increase in Battery Run Time
Nuvola Technology material scientists have designed Nimbus ZEA electrodes to be flat. This architectural feature now means that Nimbus ZEA electrodes support higher active material loadings. Depending on chemistry, battery designers can see an additional 25% boost in energy capacity from this innovative approach to small battery electrode design.

Supports High Surge Currents = 16X Longer Bluetooth Connectivity
The multiple layers of flat electrodes in small batteries built using the Nuvola Nimbus ZEA architecture have up to 8X the surface area of traditional single-layer coin cell electrode designs. This electrode surface area improvement means that batteries as small as 100 mm3 can rapidly supply the high surge currents (10-20mA) found in typical Bluetooth applications. Real-World measurements show a 16X improvement in Bluetooth connectivity time for small coin cell batteries.
Supports Non-Circular Battery Designs for Next-Gen Wearables
Unlike coiled electrodes that only fit into cylindrical cell formats, Nimbus ZEA architecture is compatible with non-circular cell designs to deliver high power and safe batteries in various shapes for the next generation of wearable technologies.
