Abstract

original image

A cathode for high-rate performance lithium-ion batteries (LIBs) has been developed from a crystal habit-tuned nanoplate Li(Li0.17Ni0.25Mn0.58)O2 material, in which the proportion of (010) nanoplates (see figure) has been significantly increased. The results demonstrate that the fraction of the surface that is electrochemically active for Li+ transportation is a key criterion for evaluating the different nanostructures of potential LIB materials.
