PURPOSE:To improve life of a nonaqueous secondary battery using a lithium alloy negative electrode. CONSTITUTION:A lithium alloy negative electrode is manufactured using powdery material to be the lithium alloy negative electrode having a porosity within a range of 20-35%. As a result, electric contact in alloy active materials can be kept, volume expansion of the alloy active material by charge/discharge can be reduced, and breakage of the alloy active material can be restricted to prevent deterioration of the negative electrode, thereby a long life of a secondary battery can be achieved. |
