Amprius SiCore product page: "SiCore delivers up to 450 Wh/kg". Amprius Q3 2026 product catalog: silicon-anode cells "offer up to 450 Wh/kg and 1,150 Wh/L — among the highest levels commercially available today". Specific catalog SKUs also list 400 and 395 Wh/kg including packaging. SiCore 500 (500 Wh/kg) is announced for commercial availability in Q4 2026 and is not treated as shipping in this row.Rank 04 of 5
