Prediction of various discarded lithium batteries in China

Various lithium batteries including primary lithium batteries (PLBs) and rechargeable lithium batteries (RLBs) have been extensively used in electrical and electrics. China as a populous and rapid developing country has become an important manufacturer, consumer and supplier of lithium batteries. This paper predicates the amount of various discarded lithium batteries based on the latest statistics and models. The discarded PLBs as a typical utilization in micro-computer is forecasted and exceed 200 metric tons in 2020. However, pushing by the electric vehicle industry, the quantity and weight of discarded RLBs in 2020 can surpass 25 billion units and 500 thousand metric tons, respectively. Further, China will reveal a much rapider speed of discarding of lithium batteries than total global level.
