(EP814531-A2)      The micro capsule content secondary cell contains an electrolyte (105) between a negative electrode (101) and a positive electrode (103). The negative electrode is characterized by the presence of a negative electrode collector object (102), while the positive electrode contains a positive electrode collector object (104). A separator (108) is provided to isolate the opposite polarity electrodes. The whole setup is housed within a battery case (109). The polymerization start agent is contained within mirror capsules (110). These chemical substances are characterised by the presence of hydroxyl group. These microcapsules are either present in the electrolyte or in the separator.    ADVANTAGE -   Forms secondary cell with high energy density. Improves safety of battery operation even after repetitive charging and discharging operations.
