Resultant Material

We report an effective approach to fabricate layered-spinel capped nanotube assembled 3D Li-rich hierarchitectures as a cathode material for Li-ion batteries. The resultant material exhibits a reduced first-cycle irreversible capacity loss, rapid Li-ion diffusion rate and excellent cycle stability.

Powder Addition

Natural graphite anodes were treated by different methods to improve their cyclability. We tried following methods; heat-treatment at 550oC for graphite powder, addition of carbon black for electrode and VC (vinylene carbonate) in electrolyte. All methods decreased capacity fade rate during constant cycling. The addition of carbon black decreased capacity fade significantly but increased irreversible capacity much at first cycle. Heat-treatment and VC were also effective for cycling and irreversible capacity loss.

Eis Measurements

Microstructure and self-discharge characteristics of Ti-Zr-V-Cr-Ni-Ce hydrogen storage electrode have been investigated by XRD, FESEM-EDS and EIS measurements. Self-discharge properties indicate that the irreversible capacity loss is negative, which is different from that of AB5 alloy electrode. The capacity loss can be divided in two parts, one is due to the deterioration of the hydrogen storage alloy, which will result in the decrease of discharge capacity, and the other is due to the continually activated, which will result in the increase of discharge capacity.
