The invention relates to a
battery cell consistency sorting method applied to
energy storage lithium batteries of
semiconductor factories. The method comprises the following steps that charging capacity, discharging capacity,
internal resistance, constant-current charging ratio and multiplying power screening is carried out, the batteries in the same batch are discharged and then charged, and the batteries of which the difference value between the charging capacity and rated capacity meets the requirement are screened out; the screened batteries are discharged and then charged, and the batteries of which the difference value between the
discharge capacity and the rated capacity and the
discharge capacity meet the requirements are screened out; and the screened batteries are charged, the batteries with the
internal resistance difference less than or equal to 0.2 milliohm are screened out, and the ratio of the constant-current charging capacity to the charging capacity is greater than or equal to 98%. The screened batteries are charged and then discharged, and the batteries with the
voltage drop larger than or equal to 2.85 V and the ratio of the discharging capacity to the rated capacity larger than or equal to 90% are screened out. The method has the advantages that the screened
lithium ion batteries can keep good battery consistency in the aspects of charging capacity, rate
discharge and the like, and in addition, the
lithium ion batteries screened by the screening standards related to charging capacity, rate discharge and the like are more suitable for the
semiconductor factories.
