Many efforts have been focused on the investigations and improvements of RNZBs in recent decades, and it is necessary to summarize and review the achievements and challenges in this advancing field. In this paper, we review various batteries, compare and highlight the advantages of RNZBs, and introduce the recent advances in the development of electrode materials and electrolytes of RNZBs,especially the applications of novel nanostructured materials for the active electrodes. Some prospective investigation trends of RNZBs are also proposed and discussed.展开更多

However, the inherent bottleneck of Li metal anodes, especially the growth of Li dendrites and the related safety concerns, should be well addressed. Owing to their featured micro-/nano-porous structures and intriguing physical properties, nanocarbon materials have been applied as host materials for Li metal anodes. This review summarizes the recent progress in the development of porous nanocarbon materials for safe Li metal anodes. The perspectives regarding the challenges and future development of employing micro-/nano-porous carbon materials in Li metal anodes are also included.展开更多
