Self-templating fabrication of Ti-doped SnO2 @carbon nanotubes via electrospinning for high-performance lithium-ion batteries

Wrapping Porous Hierarchical Co3O4 Nanospheres within Reduced Graphene Oxide Nanosheets for High-Performance Lithium Storage

“…Lithium-ion batteries (LIBs) have been widely used in the energy storage field over past decades; however, the state-of-the-art anode material, graphite, displays a limited theoretical capacity of 372 mA h g –1 , and the potential Li dendrite induced safety issue. − Thus, it is still critical to develop new anode materials with high theoretical capacity and distinctive architecture. Transition metal oxides (TMOs) are promising LIB anode materials owing to their high theoretical capacities and abundant resources. − Among various TMOs, spinel Co 3 O 4 can deliver a theoretical capacity of 890 mA h g –1 via conversion reaction (Co 3 O 4 + 8Li + + 8e – ↔ 3Co + 4Li 2 O). − More importantly, the lithiation potential of Co 3 O 4 is around 1 V (vs Li/Li + ), which can avoid the lithium dendrite formation .…”
