Battery electrode materials by electrospinning
Changbao Zhu, Yan Yu
In the past decades the electrospinning technique was mainly used to produce polymer fibers. Only recently more and more composite fibers are prepared by this technique. In our group, we obtain by electrospinning nanowires or nanotubes of metal, oxides and sulfides, but also of more complex materials such as LiFePO4. The special 1D morphology of these materials used in lithium based batteries can provide great benefit to the electrochemical performance.
