Lithium battery question

  1. Jan 31, 2008 #1
    I want to ask you something. What happens with the lithium battery (lets say after 100 times of recharging) and loses its capacity after 2 years recharging? Is it something with the ions or what?

    Theoretically, it is a kind of reversible reactions : charged and discharged. But batteries do aging. It is because of the microstructure of the materials : The porosity is degrading, so reacting area or active area deduces over time, sintering etc..

    You say that negative electrode corrode, right?
