La2O3 hollow nanospheres for high performance lithium-ion rechargeable batteries

An efficient and simple protocol for synthesis of novel La2O3 hollow nanospheres of size about 30 ± 2 nm using polymeric micelles is reported. The La2O3 hollow nanospheres exhibit high charge capacity and cycling performance in lithium-ion rechargeable batteries (LIBs), which was scrutinized for the first time among the rare-earth oxides.
