  • Lithium battery failure model-explain the phenomenon of lithium evolution in graphite anode: part-2

    Lithium battery failure model-explain the phenomenon of lithium evolution in graphite anode: part-2

    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...

  • What is Thermal runaway and what is its impact on cell chemistry?

    What is Thermal runaway and what is its impact on cell chemistry?

    Jan , 06 2022
    One of the main causes of danger for lithium-ion cells is related to the phenomenon of thermal runaway. This is a healing reaction of the battery in use, caused by the nature of the materials used in the chemistry of the battery. Thermal runaway is mainly caused by the solicitation of batteries under specific conditions, such as overload under adverse climatic conditions. The result of a thermal r...

  • 4 Ways Lithium Batteries Power Up Solar

    4 Ways Lithium Batteries Power Up Solar

    Jan , 17 2022
    Investing in solar is smart; pairing solar with a lithium battery storage unit is even smarter. While lithium batteries tend to be a higher initial investment than lead acid batteries, their superior performance and longevity makes them an ideal choice for off-grid and grid-tie applications. When selecting a battery to complement your solar system, understanding the advantages that lithium batteri...
