摘要： A positive electrode for a lithium battery wherein nickel oxyhydroxide is held in an electro-conductive three-dimensional porous material or a sintered nickel substrate and a lithium battery using it. When the three-dimensional porous material is used, the electric contact of the active material and the current collector is good, also the contact state of nickel oxyhydroxide particles, which are active materials, each other is good, further, the contact resistance among the particles is low, and also the diffusion of the lithium ion, which is the rate-determining step of the reaction, becomes easy among the particles. Furthermore, in a positive electrode for a lithium battery wherein lithium is intercalated into nickel oxyhydroxide by discharging and lithium is disintercalated from nickel oxyhydroxide by charging, the positive electrode contains at least one kind selected from the group of cobalt oxyhydroxide, metallic cobalt, cobalt oxide, tricobalt tetroxide, lithium cobaltate, and proton-containing cobalt dioxide.
