Abstract
Official abstract text for this publication.
This positive electrode precursor includes: a positive electrode active material containing a carbon material and an alkali metal compound, wherein 5≤A≤35, when A (g/m 2 ) is a weight of the alkali metal compound in the positive electrode active material layer at one surface of the positive electrode precursor, 10≤B≤100 as well as 0.20≤A/B≤1.00, when B (g/m 2 ) is a weight of the positive electrode active material in the positive electrode active material layer, and 1≤C≤20, when C (m 2 /cm 2 ) is a specific surface area per unit area as measured by the BET method at one surface of the positive electrode precursor.
First claim
Opening claim text (preview).
The invention claimed is: 1. A positive electrode precursor comprising: a positive electrode active material containing a carbon material; and an alkali metal compound, wherein the positive electrode precursor has one surface and another surface, and a positive electrode active material layer is present at the one surface or both the one surface and the other of the positive electrode precursor, wherein 24.2≤A≤42.1, when A (g/m 2 ) is a weight of the alkali metal compound in the positive electrode active material layer at the one surface of the positive electrode precursor, wherein 10≤B≤100 as well as 0.20≤A/B≤1.00, when B (g/m 2 ) is a weight of the positive electrode active material in the positive electrode active material layer, and wherein 1≤C≤20 as well as 0.116≤C/B≤0.5, when C (m 2 /cm 2 ) is a specific surface area measured by the BET method using nitrogen as an adsorbate at the one surface of the positive electrode precursor per unit area of the one surface of the positive electrode precursor.
