Super-stable antinomy carbon composite anodes to boost potassium storage performance

NanoWerk.com - Mon, 01/21/2019 - 08:59
Potassium-ion batteries (PIBs) have been considered as promising alternatives to lithium-ion batteries due to the rich natural abundance of potassium and similar redox potential with Li+/Li. Recently, researchers have designed and fabricated a novel antimony carbon composite PIB anode via a facile and scalable electrospray-assisted strategy and found that this anode delivered super high specific capacities as well as cycling stability in a highly concentrated electrolyte. These encouraging results will significantly promote the deep understanding of the fundamental electrochemistry in Potassium-ion batteries as well as rational development of efficient electrolyte systems for next generation high-performance Potassium-ion batteries.
