NEXOGEL IonGel Flex™ Lineup

We design flexible battery solutions tailored for specific devices — from TWS earbuds to medical skin patches and smart textiles.

NanoStrip Series

For TWS earbuds and headsets

Narrow, flexible cells shaped for ear hooks and compact enclosures. Ideal for premium audio devices and voice-assistant hardware.

Capacity: 60–120 mAh · Thickness: 0.4–0.6 mm · Fast charge 3C–5C.
FlexBand Series

For watches, bands and trackers

Curved batteries integrated into the band or chassis. More runtime without increasing size or compromising comfort.

Capacity: 150–400 mAh · Flex durability: > 10,000 bends.
ThinCell Series

AR/VR, smart glasses & skin patches

Ultra-thin pouch cells designed for glasses, headsets and medical patches. Maximum energy density in minimal volume.

Thickness: from 0.3 mm · Fully custom dimensions and curvature.
Technology

Next-generation gel chemistry

NEXOGEL is based on ion-gel electrolyte, organic electrode materials and roll-to-roll manufacturing — enabling unique flexibility, safety and fast-charging performance.

Ion-gel instead of liquid electrolyte

Gel electrolyte is puncture-resistant, stable under vibration and does not leak — drastically reducing fire risk and enabling thin flexible designs.

Less casing rigidity required, more design freedom.

Organic cathodes & ultra-fast charging

Radical polymer materials provide extremely fast charge transport and support high-C charging without rapid degradation.

0–80% charge in 3–5 minutes with proper BMS.

Roll-to-roll manufacturing

Layer-by-layer deposition on flexible substrates enables economic production of long, curved and complex-shaped batteries.

Scalable to gigawatt-hour factories with low CAPEX.
5000+ cycles at 80% capacity retention
< 5 min to 80% (fast-charge mode)
0.3 mm minimum cell thickness
0% free liquid electrolyte
