Energy storage device
First Claim
1. An energy storage device comprising:
- at least one negative electrode comprising a mixed electrode comprising;
a region of a battery electrode material and a region of a capacitor electrode material in an amount of 1% to 15% by weight of the battery electrode material, andat least one positive electrode, wherein the positive electrode comprises a positive battery electrode material mixed with a charging ability-increasing additive selected from one or a mixture of;
(a) carbon nanomaterial, vapour grown carbon fibre, fullerene, or a mixture thereof, and(b) tin dioxide conductive materials,and wherein the amount of the charging ability-increasing additive in the positive electrode material is between 0.05-10% by weight, based on the total weight of positive electrode material.
