Claim 7:
8. A positive electrode coating liquid comprising all solid contents containing a carbon material, lithium transition metal oxide, and an alkali metal compound in a dispersion solvent, wherein
a weight proportion X1 of the carbon material accounts for 50.1% by weight or greater and 65% by weight or less, a weight proportion X2 of the lithium transition metal oxide accounts for 10% by weight or greater and 30% by weight or less, a weight proportion X3 of the alkali metal compound accounts for 24.6% by weight or greater and 50% by weight or less, with respect to a total solid content in the positive electrode coating liquid,
X2/X1 is 0.19 or greater and 1.10 or less, X1/X3 is 0.65 or greater and 2.88 or less, and TI2/TI1 is 0.50 or greater and 1.20 or less, where a thixotropy index value of the positive electrode coating liquid is TI1 and a thixotropy index value after the electrode coating liquid has been allowed to stand for 24 hours following measurement of TI1 is TI2,
the carbon material in the positive electrode active material layer is activated carbon material, and
the alkali metal compound is at least one selected from the group consisting of lithium carbonate, sodium carbonate, and potassium carbonate.
