The current development and problems of gel polymer electrolyte ( GPE) are summarized
especially the two novel kinds of modifying GPE .The conductivity of nanocomposite gel polymer electrolyte (NGPE) is higher than normal GPE .In addition
owing to the reducing of the crystallinity of the polymer matrix
the stability and the mechanical properties of GPE are improved .For the microporous gel electrolyte
the conductivity and the dimensional stability increases in a wider temperature range .Finally
