Cover Feature: Enabling the Use of Lithium Bis(trifluoromethanesulfonyl)imide as Electrolyte Salt for Li‐Ion Batteries Based on Silicon Anodes and Li(Ni_0.4Co_0.4Mn_0.2)O₂ Cathodes by Salt Additives (Batteries & Supercaps 6/2024)

The Cover Feature showcases a practical organic electrode material comprising zinc porphyrin and ferrocene in a single molecule. Its sodium battery exposed a durably reversible 118 mA h g−1 capacity at 200 mA g−1, thereby demonstrating superior rapid electrochemical charge-storage capacity and stable cycling performances than its parallel free base and nickel porphyrin electrodes.
