A lithium polymer cell, comprising:
- a positive electrode plate, a separator membrane, a negative electrode plate, a separator membrane and a positive electrode plate which are sequentially arranged;
- wherein the positive electrode plate includes the mixture of adhesives, conductive carbon, activating substance and two kinds of solvents;
- the negative electrode plate includes the mixture of adhesives, conductive carbon, activating substance and two kinds of solvents;
- and
- the separator membrane includes the mixture of adhesives, filler and two kinds of solvents;
- wherein the two kinds of solvents which have different boiling points;
- when one of the solvents evaporates, the separator membrane still have another solvent so that the separator membrane has a form of gel, and thus the separator membrane can be adhered to the negative electrode plate and positive electrode plate;
- and each of the mixtures of the negative electrode plate and positive electrode plate contain at least one solvent, when one of the solvent evaporates, another solvent can retain the flexibility of the electrodes.
