More Advanced Battery Platforms
SWIFT Semi-Solid State Batteries
The SWIFT platform is Enpower's flagship aerospace-grade semi-solid state battery, engineered for aviation applications — industrial drones, eVTOL, and heavy-load drones — with breakthroughs in lightweight design, flight range, temperature adaptability, and instant power response. With energy density up to 403 Wh/kg and over 3 million cells delivered, SWIFT is proven at industrial scale.
FLEET Quasi-Solid State Batteries
FLEET pairs a lithium-metal anode with a quasi-solid electrolyte to hold stable power output in the extreme cold and high radiation of the stratosphere, down to -60°C. With cell energy density up to 525 Wh/kg, FLEET powers pseudo-satellites and high-altitude drones for weeks or even months — a key energy carrier for 'never-landing' airborne base stations.
