2 EXTREME THERMAL STABILITY

ENHANCED PERFORMANCE

3 ENHANCED CYCLE STABILITY

LONG-TERM RELIABILITY

Optimized Ion Transport

With 50-60% porosity and sub-300 nm pore size, ions move faster across the separator. Combined with <2s electrolyte wetting, the result is high-rate charging and discharging with low internal resistance and exceptional energy transfer efficiency.
