The potassium-ion batteries (PIBs) worth considering as a possible alternative for stationary energy storage technology. Among numerous negative electrode (anode) materials for PIBs the carbon-based ones attract much attention as they deliver high electronic conductivity and promising electrochemical characteristics at relatively low cost.
Potassium-ion batteries (PIBs), working on the same rocking-chair principle, have gained increasing attention as a “beyond-Li-ion” battery technology due to the reduced economic cost and the promising potential for large-scale energy storage.
