"Recent progress on alloy-based anode materials for potassium-ion batte" by Qiuran Yang, Qining Fan et al.

Potassium-ion batteries (PIBs) are considered as promising alternatives to lithium-ion batteries due to the abundant potassium resources in the Earth’s crust. Establishing high-performance anode materials for PIBs is essential to the development of PIBs. Recently, significant research effort has been devoted to developing novel anode materials for PIBs. Alloy-based anode materials that undergo alloying reactions and feature combined conversion and alloying reactions are attractive candidates due to their high theoretical capacities. In this review, the current understanding of the mechanisms of alloy-based anode materials for PIBs is presented. The modification strategies and recent research progress of alloy-based anodes and their composites for potassium storage are summarized and discussed. The corresponding challenges and future perspectives of these materials are also proposed. ....

"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 conductivity, high capacity, and high chemical and structural stabilities is always at the heart of rechargeable battery studies. In this review, we comprehensively review five types of anode electrodes for PIBs, including K-metal, intercalation, conversion, alloying, and conversion-alloying in terms of materials synthesis, electrochemical characters, and functional mechanisms. The most recent progr ....
