Deciphering the interaction mechanism between copper and polysulfides for enhanced performance and cost-efficiency in quasi-sodium-sulfur batteries
Room-temperature Na-S batteries with Al current collectors face the long-standing challenges of poor cycling performance and rate capability due to the serious sodium polysulfides (NaPSs) shuttling and sluggish reaction kinetics. Here, we demonstrate that a high-performance and low-cost quasi-Na-S battery can be realized by using the Cu@carbon nanotube (CNT) cathode host and unconventional Cu current collector (Cu-CC) in an ether electrolyte. Detailed ex-situ characterizations reveal that the Cu@CNT/S was transformed to NaPSs anchoring on Cu7S4 nanocrystals (~11 nm) during the cycling, forming the NaPS@Cu7S4/CNT cathode with robust sulfur immobilization and enhanced Na+ reaction kinetics. Mo...

Nanobatteries and Nanogenerators
The term 'nanobattery' can refer not only to the nanosized battery, but also to the uses of nanotechnology in a macro-sized battery for enhancing its performance and lifetime. Nanobatteries can offer many advantages over the traditional battery, including higher power density, shorter charging time, and longer shelf life. Nano-generators refer to the uses of nanosized devices and materials to convert mechanical, thermal and light-based energies into electricity. Similar to with traditional battery, in nanobatteries, the chemical energy is converted into electricity. This book addresses the fundamental design concepts and promising applications of nanobatteries and nanogenerators. Particular ...
