FAQ
Why does a silicon–carbon anode improve energy density?
Silicon has much higher theoretical specific capacity than graphite. Using a silicon–carbon composite and optimized binder/coating systems helps manage silicon expansion while leveraging higher capacity to raise cell-level energy density.
What is the advantage of a stacked cell versus a wound cell for high energy density?
Stacking provides more orderly electrode alignment and space utilization, shorter transport paths, and improved suitability for high-compaction designs—helping translate material advantages into cell-level performance.
Why is low DC internal resistance (e.g., 3 mΩ) important?
Lower resistance reduces voltage drop and heat generation during high-current discharge, improving power response, thermal stability, and overall system efficiency—especially for demanding load profiles.
