| BTC Winding | Traditional Lamination | Remarks | |
|---|---|---|---|
| Rate Performance | Good | Good | |
| Safety | Good | Fair | 1. The total edge length of the electrode sheets in BTC winding is only 20-50% of the total perimeter in lamination, significantly reducing internal short-circuit risks. 2. BTC winding eliminates edge lithium plating during cycles, a phenomenon unavoidable in laminated cells. |
| Consistency | Good | Fair | BTC winding ensures more uniform current distribution in the cell’s current collectors. |
| Energy Density | Fair | High | BTC winding allocates internal space for enhanced safety design. |
| Manufacturing Process | Cells undergo 50°C±16h high-temperature aging before shipment | High-temperature aging: <8h | BTC winding ensures higher product reliability through prolonged aging. |
