A lead acid cell comprises a container 2 closed by a lid 10 and contains a single positive electrode member 4 separated from a single negative electrode member 6 by separator material. Each electrode member is of sheet form with n folds in it, with n=2 or more, thereby dividing each electrode member into n+1 electrodes which are arranged to be of alternating polarity. Each electrode member has n/2, when n is an even number, or (n+1)/2, when n is an odd number, of consecutive folds of one sense, the remaining folds being consecutive and of the opposite sense. Each electrode member has a connector member 8 situated adjacent the central fold, when n is an odd number, or adjacent the n/2th fold from one or the other end of the electrode member, when n is an even number. <IMAGE> |
