Method for adjusting a limit value for an anode overvoltage of a lithium-ion battery, comprising the following steps: - providing signal characteristics of the lithium-ion battery which comprise at least voltage, current and operating temperature characteristics and a capacity state of health characteristic of the lithium-ion battery; - transmitting the signal characteristics and the capacity state of health characteristic of the lithium-ion battery to a storage device, in which data relating to a plurality of lithium-ion batteries are stored which comprise at least voltage, current and operating temperature characteristics and a capacity state of health characteristic and a limit value for the anode overvoltage of the respective lithium-ion batteries; - comparing the signal characteristics of the lithium-ion battery with the data stored in the storage device and choosing comparison batteries; - investigating the data relating to the comparison batteries in order to obtain an average capacity state of health characteristic and an average capacity loss of the comparison batteries and an optimized limit value, corresponding to the average capacity loss, for the anode overvoltage; - comparing the capacity state of health characteristic of the lithium-ion battery with the average capacity state of health characteristic of the comparison batteries; - adjusting the limit value for the anode overvoltage of the lithium-ion battery to the optimized limit value for the anode overvoltage when it is identified that the capacity state of health characteristic of the lithium-ion battery is below the average capacity state of health characteristic of the comparison batteries. - providing signal characteristics of the lithium-ion battery which comprise at least voltage, current and operating temperature characteristics and a capacity state of health characteristic of the lithium-ion battery; - transmitting the signal characteristics and the capacity state of health characteristic of the lithium-ion battery to a storage device, in which data relating to a plurality of lithium-ion batteries are stored which comprise at least voltage, current and operating temperature characteristics and a capacity state of health characteristic and a limit value for the anode overvoltage of the respective lithium-ion batteries; - comparing the signal characteristics of the lithium-ion battery with the data stored in the storage device and choosing comparison batteries; - investigating the data relating to the comparison batteries in order to obtain an average capacity state of health characteristic and an average capacity loss of the comparison batteries and an optimized limit value, corresponding to the average capacity loss, for the anode overvoltage; - comparing the capacity state of health characteristic of the lithium-ion battery with the average capacity state of health characteristic of the comparison batteries; - adjusting the limit value for the anode overvoltage of the lithium-ion battery to the optimized limit value for the anode overvoltage when it is identified that the capacity state of health characteristic of the lithium-ion battery is below the average capacity state of health characteristic of the comparison batteries.
