A thin polymer shell helps V2O5 a lot. Short V2O5 nanobelts are grown directly on 3D graphite foam as a lithium-ion battery (LIB) cathode material. A further coating of a poly(3,4-ethylenedioxythiophene) (PEDOT) thin shell is the key to the high performance. An excellent high-rate capability and ultrastable cycling up to 1000 cycles are demonstrated.
一层薄薄的聚合物外壳对 V2O5 有很大帮助。V2O5 纳米带短纤维直接生长在 3D 石墨泡沫上,作为锂离子电池(LIB)的阴极材料。进一步涂覆一层聚(3,4-乙撑二氧噻吩)(PEDOT)的薄壳是实现高性能的关键。该材料表现出优异的高倍率性能和超稳定的循环性能,循环 1000 次后仍保持稳定。
