Abstract
The present invention relates to a lithium-ion battery including: a positive electrode including an active positive electrode material, and advantageously a lithium salt; an electrolyte including a lithium salt; and a negative electrode including an active negative electrode material, and advantageously a lithium salt. In this battery, the positive electrode, the negative electrode, and the electrolyte all three appear in the form of gels, and all three include a polymer and a dinitrile compound of formula N≡C—R—C≡N; R being a hydrocarbon group CnH2n, n being an integer between 1 and 2; the weight ratio of the dinitrile compound to the polymer being in the range from 60/40 to 90/10.
