Abstract
The present invention relates to a solid composite cathode comprising a polymer electrolyte and high-potential NMC type cathode active material. The polymer electrolyte comprises an electrolyte composition, preferably comprising a deep eutectic solvent (DES), and a polymer network having a polyacrylamide backbone.
Claims19
1-15. (canceled)
A composite cathode comprising cathode active material and a polymer electrolyte,
- wherein the cathode active material comprises Li, M and O, wherein M comprises Ni and one or both of Mn and Co,
- wherein the polymer electrolyte comprises an electrolyte composition and a polymer network,
- wherein the electrolyte composition comprises a deep eutectic solvent (DES),
- wherein the polymer electrolyte is obtainable by polymerizing a precursor composition comprising the electrolyte composition and a first monomer according to formula (I)
- wherein
- R1 represents a first substituent having from 1 to 8 carbon atoms and optionally comprising at least one functional group selected from alcohols, amines, ethers, ketones, amides, acetals, ketals, aminoacetals, hemiaminal ethers or combinations thereof;
- and
- wherein R2 represents H or a second substituent having from 1 to 8 carbon atoms and comprising at least one functional group selected from alcohols, amines, ethers, ketones, amides, acetals, ketals, aminoacetals, hemiaminal ethers or combinations thereof;
- wherein R3 is selected from H, methyl or ethyl;
- and
- wherein n is an integer from 1 to 5.
