  • What is the experimental evidence of side effects of lithium deposition, collected from different angles?

    What is the experimental evidence of side effects of lithium deposition, collected from different angles?

    Sep , 30 2021
    When charging lithium ion battery, Lithium precipitation not only reduces the performance of the battery and greatly shortens the cycle life, but also limits the fast charging capacity of the battery, and may cause disastrous consequences such as combustion and explosion. In a series of articles we will discuss about the problems from the macro scale of lithium-ion battery, working conditions, gra...

  • Lithium battery failure model-explain the phenomenon of lithium evolution in graphite anode: part-1

    Lithium battery failure model-explain the phenomenon of lithium evolution in graphite anode: part-1

    Nov , 01 2021
    During the long-cycle cycle, the reversible capacity of the lithium-ion battery will continue to decrease due to the reduction of active materials, the precipitation of metal lithium, the continuous consumption of electrolyte, the increase of internal resistance and thermal runaway. Among them, the lithium evolution phenomenon of the graphite negative electrode is the most important cause of batte...

  • Three things the energy storage industry should know about end of battery life

    Three things the energy storage industry should know about end of battery life

    Nov , 12 2021
    In the latest update of Circular Energy Storage’s data on the lithium-ion battery end-of-life market we conclude that over 1.2 million tons of waste batteries will be recycled in 2030. Although it sounds like a massive number, the recycling industry is in fact well prepared and will most probably fight for the volumes. This is good news for the energy storage industry, as it is for all other busin...
