  • Impact of high temperature on battery safety performance

    Impact of high temperature on battery safety performance

    Mar , 30 2024
    Lithium battery temperature is too high, more than 45℃ Lithium-ion batteries are more and more widely used in people's production and life, which makes its temperature environment become the main point of concern, relatively speaking, lithium batteries are easier to produce safety problems in high temperature environment, therefore, it is necessary to test the high temperature performance of lithi...

  • Reason analysis of low capacity of lithium battery cell

    Reason analysis of low capacity of lithium battery cell

    Apr , 13 2024
    In the process of lithium battery manufacturing, the capacity of lithium battery cells is sometimes lower than expected, which not only affects the performance of the battery, but also shortens its service life. This paper will deeply analyze the reasons for the low capacity of lithium battery cells, in order to provide reference for related research and production. 1. Excessive and insufficient n...

  • Long-term storage methods for lithium batteries and storage requirements for lithium iron phosphate batteries

    Long-term storage methods for lithium batteries and storage requirements for lithium iron phosphate batteries

    Apr , 20 2024
    What impact will the lithium battery have after being put aside for a long time? When the lithium battery is idle, due to the nature of the battery itself, self-discharge, passivation of positive and negative electrode materials, electrolyte decomposition and other phenomena will occur. The instability of the negative SEI will lead to the rapid decline of the negative active substance, which is ea...

  • What is the impact of low temperature on lithium batteries and solutions

    What is the impact of low temperature on lithium batteries and solutions

    Apr , 20 2024
    The use of lithium batteries in low battery temperature environments is limited. In addition to a severe drop in discharge capacity, lithium batteries cannot be charged when the battery temperature is low. When the battery is charged at low temperature, the lithium ion embedment on the battery graphite electrode and the lithium plating reaction exist simultaneously and compete with each other. Und...
