Mesoporous CuO particles threaded with carbon nanotubes are suggested as a novel class of nanocomposite material for a high-performance anode in the lithium-ion batteries. The nanocomposite electrode exhibits a highly reversible capacity (650 mA h g(-1) at 0.1 C rate) and an excellent C rate capability (580 mA h g(-1) at 5 C, and 500 mA h g(-1) at 10 C).
Three‐dimensional porous silicon particles can be produced via the combination of a galvanic displacement reaction and a metal‐assisted chemical etching process. This simple synthetic route can be applied to make high‐performance anode materials, including high specific capacity, stable cycling retention, and high rate capability, in lithium‐ion batteries.
We demonstrate the newly developed Si-based multicomponent anodes exhibiting a highly stable cycling retention (∼65% after 1000 cycles at a 1 C discharge–charge rate).
