摘要
The invention relates to a method for evaluating the safety of a battery under an internal short-circuit condition. The battery includes an electrode assembly comprising a wound laminate of a positive electrode plate, a negative electrode plate, and a separator interposed between the positive and negative electrode plates. The positive electrode plate includes a positive electrode current collector and a positive electrode active material layer on the positive electrode current collector, and the negative electrode plate includes a negative electrode current collector and a negative electrode active material layer on the negative electrode current collector. The battery further includes an electrolyte and a casing for housing the electrode assembly and the electrolyte. The safety of the battery under an internal short-circuit condition is evaluated by causing a short-circuit only between the positive electrode active material layer of the positive electrode plate and the negative electrode plate inside the battery.
