Solid electrolyte and lithium based battery using the same

A lithium based battery, comprising:

• an anode,
• a cathode;
• and
• a solid electrolyte attached between the anode and the cathode, and the solid electrolyte comprising:
• an interpenetrating polymer network comprising CH2—CH2—n segments, and the interpenetrating polymer network formed by polymerizing a first monomer R1—OCH2—CH2—OnR2, a second monomer R3—OCH2—CH2—OmR4 and an initiator;
• and
• a lithium salt dispersed in the interpenetrating polymer network,
• wherein, each “R1”, “R2” and “R3” comprises —C═C— group or —C≡C— group;
• the “R4” comprises an alkyl group or a hydrogen atom;
• the “m” and “n” are integers;
• molecular weights of the first monomer and the second monomer are more than or equal to 100, and less than or equal to 800;
• the first monomer is less than or equal to 50% of the second monomer by weight;
• the lithium salt is less than or equal to 10% of the second monomer by weight.
