(WO9828807-A1)      Processed material for increasing the power density of lithium (Li) secondary batteries contains boric ester derivatives (I).    Also claimed is a method of producing the material.    ADVANTAGE -   The material stops the system chemically if the battery is over-loaded (claimed). The current is increased and the number of cycles is increased, without sacrificing operating safety, by increasing the conductivity and Li transport without (localised) salt depletion.
