Figure 7. TEM and elemental analyses of S-HMT@CNTs cathode cycled 100 times and then a-c) charged to 2.8 V and d-f) discharged to 1.9 V. g-j) SEM and EDX-elemental analyses of DF-PCW interlayer recovered from S-HMT@CNT cell cycled 100 times at 1C rate between 1.9 and 2.8 V.

A Li-rechargeable battery system based on state-of-the-art cathode and anode technologies demonstrated high energy density, meeting demands for vehicle application.
