Lithium ion in process of charging, Li
+Take off embedding from negative electrode and come out to enter into anode through electrolytic solution, negative pole is in rich lithium state, and positive pole is in poor lithium state, in lithium ion embedding people carbon dioxide process carbon electrode process, the lithium ion trapped electron, the compensation charge of electronics supplies to negative pole from external circuit, guarantees the charge balance of negative pole.Reversed reaction, Li take place during discharge
+Take off embedding from the negative pole utmost point and come out to enter into positive pole through electrolytic solution, promptly uncharged lithium electricity becomes Li in carbon
+The time, electronics enters into external circuit, and lithium ion migration also enters into negative electrode, and meanwhile the electronics that provides of external circuit is with the local reduction of oxide compound lattice, and the two forms cathodic current.In normal charge and discharge process, lithium ion is the interlayer embedding people of the oxide compound of the carbon material of laminate structure and laminate structure and deviate from, the general variation that only causes basal spacing, do not destroy crystalline structure, in charge and discharge process, the chemical structure of negative material is constant substantially, therefore, from the reversibility that discharges and recharges, the reaction of lithium ion should be a kind of ideal reversible reaction.
The plain powder F of charcoal series material refinery coke is that main starting material pass through 3000-3200 ℃ of high temperature graphitization in earlier stage, thereby improves degree of graphitization.The lithium cell specific storage is high more, and cycle life is long more, and stability is good more, and the battery charging and discharging rate is big more.
Equally, interlamellar spacing also depends on the degree of graphitization of carbon, and the degree of graphitization increase helps Li
+Diffusion.
The F series material adds the certain proportion additive in the second time before the high temperature, combines with doping by machinery, on above basis, adopts the technology that coats again, is made into the F primary material.With production technique such as three kinds of different-shapes and the even collocation of size granularity, in high-temperature process, when removing organic impurity, generate nanometer micropore with the high temperature cabonization device then at material surface by additive.Material shape is the class ball-type, because irregular circle can increase substantially (the pole piece compacted density 〉=1.72～1.80g/cm of compacted density in battery making processes
3) cycle life: 600～1000 all capability retentions are simplified high-end ion cathode material lithium technical process more than 85% greatly, and improve material specific capacity, improve cycle performance and processing characteristics.
