This Insight provides clarity into the current state of knowledge on LIB degradation1 and identifies where further research might have the most significant impact. Battery degradation is a collection of events that leads to loss of performance over time, impairing the ability of the battery to store charge and deliver power.
Based on the research and evaluation of the critical issues in the reusing of retired power batteries, this paper proposes some policy suggestions for the government and enterprises. First, China is about to usher in the peak period of retired power batteries, and mandatory recycling is imminent by the government.
With the decrease of the battery price and the maturity of the reusing technology, the revenue from the reuse of retired power battery will be further improved. The government and related enterprises should increase the research of battery materials and recycling technology so as to reduce the price of batteries and the cost of recycling.
