"Advanced anode materials for potassium batteries: Sorting out opportun" by Meng Ma, Shaokun Chong et al.
The development of lithium-ion batteries for the integration of renewable energy generation and the widespread use of electric vehicles has been greatly hampered by the scarcity of Li-ions as a natural resource as well as the limitation of an energy density that almost reaches the threshold. 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. Pursuing suitable electrode materials with low cost, good co...
