PROBLEM TO BE SOLVED: To provide a positive electrode plate for a lithium battery of high performance, in which electrodes can be reacted uniformly, and a lithium battery with an excellent contact between a current collector and an active substance or between active substances. SOLUTION: A positive electrode plate for a lithium battery holds nickel oxyhydroxide in a conductive three-dimensional porous body, and a lithium battery uses the positive electrode plate. Use of the three-dimensional porous body achieves excellent electric contact between an active substance and a current collector, improves the contact between particles of oxynickel hydroxide as the active substance, reduces contact resistance between the particles, and facilitates diffusion of lithium ions even among the particles during a reaction rate determining process. It is preferable that the content of cobalt should be 2-50mol%. |
