Hard Carbon Microspheres: Potassium-Ion Anode Versus Sodium-Ion Anode

Hard Carbon Microspheres: Potassium-Ion Anode Versus Sodium-Ion Anode

Hard carbon microspheres (HCS) exhibit a highly reversible capacity of 262 mAh g−1 for K‐ion batteries. They present a superior rate capability for K‐ions to Na‐ions, where at 2C, HCS/K cells deliver 190 mAh g−1 in contrast to 97 mAh g−1 from HCS/Na cells. It is determined that the K‐ion diffusion c...

Zusammenfassung:Hard carbon microspheres (HCS) exhibit a highly reversible capacity of 262 mAh g−1 for K‐ion batteries. They present a superior rate capability for K‐ions to Na‐ions, where at 2C, HCS/K cells deliver 190 mAh g−1 in contrast to 97 mAh g−1 from HCS/Na cells. It is determined that the K‐ion diffusion coefficient of HCS is higher than that of Na‐ions.
