Abstract: This application provides a method for supplementing lithium for a secondary battery and a method for charging and discharging a secondary battery. The method for supplementing lithium includes: performing a first round of lithium-supplementing charge and discharge on the secondary battery during routine charge-and-discharge cycles of the secondary battery if a capacity of the secondary battery has faded by k1 in comparison with an initial capacity, and then performing a round of lithium supplementing on the secondary battery if the capacity of the secondary battery has faded by k2 in comparison with the capacity achieved after a previous round of lithium supplementing, where k1 and k2 each are 1.5% to 17% independently, a number of times of charge and discharge in each round of lithium supplementing is at least one, and a charge cut-off voltage is 4.45 V to 5 V. A positive electrode plate includes a lithium supplement material. The lithium supplement material is at least one selected from Li 2 O, Li 2 O 2 , Li 2 S, Li 6 CoO 4 , Li 5 FeO 4 , Li 2 NiO 2 , Li 2 DHBN, Li 2 C 2 O 4 , and xLi 2 MnO 3 ·(1-x)LiNi y1 Co y2 Mn y3 O 2 , where 0 < x ≤ 1, and y1, y2, and y3 each are 0 to 1 and add up to 1. This application increases the cycle capacity retention rate and the life of the battery, and achieves a high energy density of the battery.
