Effect of Graphite Particle Size on Irreversible Capacity Loss

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.

Graphite Intercalation

Three natural graphite flakes (35, 50 and 80 mesh) were used as raw material. Exfoliated graphite (EG) was prepared by rapidly heating residue H2SO4-graphite intercalation compounds (RGIC) in a muffle and by irradiating it in a microwave oven, respectively. Results show that the exfoliation volume of EG decreases with decreasing the raw graphite particle size. Compared with muffle heating, microwave irradiation is more helpful for the exfoliation of RGICs, especially for the small particle samples.
