<P>PROBLEM TO BE SOLVED: To solve a problem of a preservation property being degraded by reacting of a negative electrode active material and electrolyte solution at a cell preservation when a lithium metal, a lithium alloy, and a carbon material or the like are used as a negative electrode active material, and a clad material of aluminum/stainless steel or aluminum/iron with its inner surface in aluminum is used as a positive electrode can. <P>SOLUTION: The lithium secondary cell uses silicon as a negative electrode active material, and a clad material of aluminum/stainless steel or aluminum/iron as a positive electrode can with its inner surface in aluminum. <P>COPYRIGHT: (C)2004,JPO |
