Additives for Fast Chargeable Lithium Ion Batteries |
摘要 |
A porous graphene material with 1 to 200 graphene layers, wherein: at least one monolayer graphene is included; pores with the size of 70 nm to 200 nm are scattered over the surface of the material and the number of pores is 10 to 500 per μm2; an oxygen concentration is below 0.8 atomic%; and the ratio of the peak height (ID) of D band in a Raman scattering spectrum of the material to that of the peak height (IG) of G band at 1,570 to 1,596 cm?1 in the spectrum (ID/IG) is between 1 and 1.35. The porous graphene material is suitable for conductive additives for electrodes of Lithium ion battery. |
