66AH HIGH-PERFORMANCE AND HIGH-SAFETY SOLID-STATE BATTERY | ATOMFAIR

COMMERCIAL GRADE · PRODUCTION

Product Overview

Engineered for high-capacity energy storage applications, this premium pouch cell utilizes an advanced high safety solid state battery framework. Implementing an optimized NCM graphite silicon pouch cell matrix (NCM-Gr/Si,C-SSE), this cell leverages a composite solid-state electrolyte to deliver a remarkable 310 Wh/kg energy density and 625 Wh/L volumetric layout. This 66Ah 3.65V battery architecture supports a secure 5C maximum continuous discharge, an 8C peak discharge burst (30s), and a 3C continuous charge capability. Designed to withstand intensive operational cycles, it maintains strong capacity retention under continuous use from -30°C up to 70°C. It serves as an essential primary cell hardware standard for electric vehicle powertrains, low-altitude aircraft (eVTOL) prototyping, and marine electric vessel development workflows.
