After the initial charge and discharge of 100 active lithium ions, only 88 can continue to be recycled. The reason for the loss of 12 lithium ions was that 8 lithium ions were lost in the first effect of the negative pole, and 4 lithium ions were left in the negative pole and could not return to the positive pole due to the lack of space for lithium insertion due to the first effect of the positive pole. When the positive first effect is 88% and the negative first effect is 92%, the full battery first effect is 88%, equal to the lower positive effect. PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC will effectively improve the above situation.
And when the negative first effect is lower, such as lithium cobaltate positive to graphite negative, the whole battery first effect is equal to the lower first effect of the negative electrode. The first efficiency of the whole cell is equal to the first efficiency of the anode and cathode materials. For the whole battery, the formation factors of PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC with the first efficiency are also related to the side effects of the first charge and discharge and the different voltage range of the first charge and discharge (starting at 0V for charge and ending at 2.5-3.0V for discharge).
However, PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC factor does not significantly affect the above conclusion. The calculation method of the first efficiency of the whole battery is divided discharge capacity/(formation and charge capacity + charge capacity of the first step of separation). In addition, we know the determinant of full battery first effect: full battery first effect equals the lower of positive and negative first effect.
