Beschreibung
Zusammenfassung:	An electrochemical apparatus including a negative electrode active substance. The negative electrode active substance includes a first active substance and a second active substance, a discharge capacity per unit mass of the first active substance is smaller than that of the second active substance, and a life cycle of the electrochemical apparatus includes N cycle segments arranged sequentially, where N is a positive integer greater than or equal to 2, each cycle segment includes at least one charge-discharge cycle of the electrochemical apparatus, and the electrochemical apparatus is charged and discharged cyclically based on the ith discharge cut-off voltage in the ith cycle segment, where 1≤i≤N and the ith discharge cut-off voltage between the 1st discharge cut-off voltage and the (N−1)th discharge cut-off voltage is smaller than the (i+1)th discharge cut-off voltage.
