Thin lithium secondary cell

A lithium secondary battery, comprising:

• a positive electrode and a negative electrode opposed to each other;
• a separator disposed between the positive electrode and the negative electrode;
• and
• an electrolyte comprising a liquid electrolyte and an organic polymer,
• wherein the positive electrode or the negative electrode contains said electrolyte,
• wherein the organic polymer contains a first chemical structure and a second chemical structure, the first chemical structure is at least one of an ethylene oxide structure or a propylene oxide structure, and the second chemical structure is at least one connecting group selected from the group consisting of:
• wherein the organic polymer is formed by polymerzing an organic monomer having a polymerizable functional group at its molecular chain end.
