6.0 V High‐Voltage and Concentrated Electrolyte toward High Energy Density K‐Based Dual‐Graphite Battery

K‐based dual‐carbon batteries (K‐DCBs) integrate the advantages, including high‐voltage, low‐cost, and environmentally friendliness of dual‐ion batteries (DIBs), and large abundance of K, thus attracting much attention in large‐scale energy storage application. However, most currently used electroly...

Description
Summary:K‐based dual‐carbon batteries (K‐DCBs) integrate the advantages, including high‐voltage, low‐cost, and environmentally friendliness of dual‐ion batteries (DIBs), and large abundance of K, thus attracting much attention in large‐scale energy storage application. However, most currently used electrolytes based on KPF6 and carbonate solvents commonly suffer from poor oxidation potential (
