Inorganic cathode materials for potassium ion batteries

Promise and reality of organic electrodes from materials design and charge storage perspective

“…113,114 Accordingly, achieving viable electrode materials for K-ion batteries with both high-capacity and consistent cycling capability remains a big challenge. 115,116 Here we show conjugated microporous polymers (CMPs) as an example of the host electrode for K-ion batteries, which does not imply any limitation of the application of K-ion as an active alkali metal ion in other organic systems.…”

Bimetallic-based composites for potassium-ion storage: challenges and perspectives

“…30 Since then, research interest in PIB areas has developed rapidly, and over 2500 research publications on electrode materials for PIBs have been reported. These publications include studies on cathodes, 31,32 anodes, 33,34 separators 35,36 and electrolytes. 37,38 Anode materials are found to have high theoretical specific capacitance and important roles in PIBs.…”

Boosting the fast electrochemical kinetics of Na4Fe3(PO4)2(P2O7) via a 3D graphene network as a cathode material for potassium-ion batteries

“…Solar, wind, and tide energy have been developed quickly, but their intermittency requires advanced, efficient, and environmentally friendly energy storage systems (ESSs). [4][5][6] Electrochemical ESSs are a promising candidate, among which lithium-ion batteries (LIBs) are frequently employed in markets like those for tiny portable electronic gadgets and electric vehicles with the advantages of high energy density and long cycle life. [7][8][9][10] However, the limited and unevenly distributed reserves of lithium in the earth's crust and the rising price of lithium resources have seriously hindered their practical use in massive ESSs.…”
