A Durable and High‐Voltage Mn–Graphite Dual‐Ion Battery Using Mn‐Based Hybrid Electrolytes

Rechargeable Mn–metal batteries (MMBs) can attract considerable attention because Mn has the intrinsic merits including high energy density (976 mAh g−1), high air stability, and low toxicity. However, the application of Mn in rechargeable batteries is limited by the lack of proper cathodes for reve...

description Rechargeable Mn–metal batteries (MMBs) can attract considerable attention because Mn has the intrinsic merits including high energy density (976 mAh g−1), high air stability, and low toxicity. However, the application of Mn in rechargeable batteries is limited by the lack of proper cathodes for reversible Mn2+ intercalation/de‐intercalation, thus leading to low working voltage (
