PROBLEM TO BE SOLVED: To provide a lithium ion secondary battery with high electrolyte circulation, high output capacity per volume, low voltage consumption in an electrode, and increased battery output. SOLUTION: A positive electrode supporter is a three-dimensional net structural porous body having a thickness <=150 μm, made of aluminum, an aluminum alloy, or stainless steel on at least the skeletal surface. A negative electrode supporter is a three dimensional net structural porous body having a thickness <=150 μm, made of copper, nickel, or an alloy of them on at least the skeletal surface. A secondary battery has a negative electrode prepared by supporting a lithium ion holding material in the negative electrode supporter, a positive electrode prepared by supporting an electrode active material containing lithium ions in the positive electrode supporter, and an electrolyte arranged between these electrodes, and provides the output >=1 V. |
