Previous studies have developed positive and negative electrode materials for KIBs and demonstrated several unique advantages of KIBs over LIBs and Na-ion batteries (NIBs). Thus, besides being free from any scarce/toxic elements, the low standard electrode potentials of K/K + electrodes lead to high operation voltages …
Due to the abundance of sodium and the comparable working principle to lithium-ion technology, sodium-ion batteries (SIBs) are of high interest as sustainable electochemical energy storage devices. Non-graphitizing ("hard") carbons are widely investigated as negative electrode materials due to their high sod
A pyrolyzed polyacrylonitrile/sulfur nanocomposite (SPAN) was used as a positive electrode material for a room temperature K–S battery operated in carbonate electrolyte. SPAN presented a high reversible capacity of 270 mA h g −1 (710 mA h g sulfur −1) and excellent rate performance, which demonstrate that it is a promising positive electrode …
