Abstract
A nonaqueous electrolyte battery comprises a positive electrode, a negative electrode with lithium as active material, a nonaqueous electrolyte comprising a solute and a solvent, and a separator, the nonaqueous electrolyte further comprising 3.times.10.sup.-4 to 3.times.10.sup.-2 mole/liter, preferably 1.5.times.10.sup.-3 to 6.times.10.sup.-3 mole/liter of a specific calcium salt. This battery, with the nonaqueous electrolyte incorporating the specific calcium in the specific amount, causes little self-discharge during storage, thus having excellent storage stability.
