| titleOfInvention | A kind of preparation method of positive composite material of graphene-lithium battery |
| abstract | The invention discloses a kind of preparation method of positive composite material of graphene-lithium battery; It comprises the following steps: (1) Graphene or Graphene precursor or Graphene dry powder or graphene dispersing solution and anode material of lithium battery co-precipitation-load, concrete grammar is, by Graphene or Graphene precursor or Graphene dry powder or graphene dispersing solution: anode material of lithium battery mass ratio is that 1:8-1:100 adds in solvent, concentration is made to be 1-120g/L, after add the auxiliary agent of Graphene quality 1%-10%, regulate hydrogen ion concentration for 1.0 × 10 with acidity-basicity regulatorn -5 -1.0 × 10n 2 mol/L, mixes 1-96 hours, obtains load afterproduct at 10-80 DEG C; (2) by the centrifugation of load afterproduct, wherein a kind of product is solid sample; (3) by the atmosphere roasting activation in 0.5-4 hours at 400-700 DEG C of isolated solid sample, positive composite material of graphene-lithium battery is obtained.Beneficial effect of the present invention: improve volume and capacity ratio, anti-decay property, cycle life and capacity stability high. |
