The charge transfer between sodium and oxygen can be regulated effectively by introducing transition metal components with weak hybridization with oxygen orbitals to construct stronger Na-O binding. The air stability of layered transition metal oxides can be effectively improved by increasing the binding energy of PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC. The air stability of layered transition metal oxides is closely related to the crystal accumulation parameters of dO-Tm-O/dO-Na-O.
In the positive MATERIAL half battery (positive material is positive, LITHIUM metal sheet is negative) PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC production is completed, first of all to experience a charging - discharge cycle: in the process of charging, lithium ions from the positive electrode and precipitation in the negative lithium metal sheet; When the metal is discharged, it loses electrons and forms lithium ions that pass through the electrolyte before being reembedded in the positive electrode.
The first charge capacity of a half battery is slightly higher than the first discharge capacity, that is, the LITHIUM ions that are removed from the positive electrode when charged do not return 100% to the positive electrode when discharged. The first discharge capacity/first charge capacity is the first efficiency of this half battery.
