Pseudocapacitors and redox capacitors are among the most promising candidates for high specific energy and power delivery owing to their rapid charge-discharge capability and excellent cyclic stability. In this work, high-performance, self-supported nickel cobalt tungstate electrodes are fabricated via a facile successive ionic layer adsorption and reaction (SILAR) method with varying nickel-coba…

The interfacial stability between electrolyte components and electrode materials plays a crucial role in the formation of the solid electrolyte interphase (SEI) in sodium-ion batteries.

Aluminum-air (Al-air) batteries are considered promising candidates for electrochemical energy storage due to their theoretical energy density (∼8,100 Wh kg-1), specific capacity (∼3000 mAh·g-1), low cost and the natural abundance of aluminum. However, several hurdles must be overcome before their widespread application. Notably, the aluminum anode is prone to passivation and corrosion, which red…

Silicon anodes are among the most promising candidates for next-generation lithium-ion batteries because of their exceptionally high theoretical capacity, but their practical implementation remains constrained by severe volume expansion, unstable interfacial chemistry, low initial Coulombic efficiency, and limited scalability.
