Recent nanosheet-based materials for monovalent and multivalent ions storage

Abstract Owing to the unique advantages of short solid-state diffusion length for metal ions, outstanding ability to alleviate the huge volume expansion of the electrode during repeated charge/discharge process, considerable large amount of channels for electrolyte access leading promoting fast ion diffusion between electrode, and numerous exposed active sites, nanosheet structures are regarded as the ideal electrode structures for achieving high capacity and ultrafast charge/discharge of energy storage. Herein, this review provides a comprehensive introduction of recent nanosheet-based electrode materials for high performance batteries, like monovalent ion (lithium and sodium) batteries and multivalent ion (magnesium, zinc and aluminum) batteries. Facile and simple strategies of synthesizing electrodes and different mechanisms of energy storage are presented. Furthermore, the challenges and development directions of nanosheet-based materials and rechargeable battery systems are discussed.
