A company called Eamex in Osaka, Japan discovered a major weakness in Lithium Ion Batteries, and fixing this problem could allow them to be used for 20 years or 10,000 charges.  The secret, they have found, is in the tin used in the battery’s negative electrode.  Apparently it weakens through many cycles of charging and recharging.  The new design will use a tin-coated resin that will stabilize the electrode and prevent it from wearing down.  Well that was easy enough.
