摘要： A method for testing a precursor of a secondary cell with high reliability and high efficiency to judge the precursor to be acceptable or defective. The current flowing when a test voltage is applied between a pair of electrodes is measured before an electrolyte is placed between the electrodes. If a current the current value of which exceeds a predetermined reference current value (13) is detected during the time from the start of application of a voltage to a normal secondary cell precursor until the current becomes constant, the precursor is determined to be defective.

摘要： A battery has an electrode with a mixture layer including electroactive material formed on a current collector whose exposed part is welded to a lead, and also a separator that shrinks with heat. In the battery, a heat shrinkage-preventing layer is provided on a portion of the separator that faces the lead. As a result, even if a minor short-circuit occurs and a large amount of current is flown to a minor short-circuit region, the heat shrinkage-preventing layer prevents expansion of a short-circuit area resulting from heat shrinkage of the separator. Thus, a conspicuous decrease in battery properties is prevented.
