Discharge Capacity Performance at Different Rates
Comparison of discharge capacity for three silicon-carbon anodes under different discharge rates (0.2C to 3C).
The samples are, in order: competitor silicon-carbon anode (15% Si/C), S-Insight silicon-carbon anode (15% Si/C), and S-Insight silicon-carbon anode (25% Si/C).
At the same 15% silicon content, S-Insight's silicon-carbon anode demonstrates better capacity performance than the competitor and can be stably extended to 25% silicon content.
Discharge Capacity Performance at Different Temperatures
Comparison of discharge capacity for three silicon-carbon anodes at different temperatures (-20°C to 60°C).
The samples are, in order: competitor silicon-carbon anode (15% Si/C), S-Insight silicon-carbon anode (15% Si/C), and S-Insight silicon-carbon anode (25% Si/C).
At the same 15% silicon content, S-Insight's silicon-carbon anode demonstrates better capacity performance than the competitor and can be stably extended to 25% silicon content.
DCIR (Direct Current Internal Resistance)
Variation in DCIR of three silicon-carbon anodes across different SOC levels.
In the 50–100% SOC range, S-Insight silicon-carbon anode maintains internal resistance performance comparable to that of the competitor.
As SOC decreases below 50%, all cells show an increasing DCIR trend. At the same 15% silicon content, S-Insight's silicon-carbon anode demonstrates better internal resistance performance than the competitor and can be stably extended to 25% silicon content.
