摘要： A lithium ion secondary battery includes an electrode assembly configured such that positive and negative plates are wound or stacked with a separator interposed therebetween. The positive plate is configured such that positive-electrode mixture layers are formed on both surfaces of a positive-electrode current collector. The negative plate is configured such that negative-electrode mixture layers are formed on both surfaces of a negative-electrode current collector. The positive-electrode mixture layers formed on the positive plate each have a larger porosity than the negative-electrode mixture layers formed on the negative plate. A more refractory porous layer 1 than the separator is formed between the negative plate and the separator. The porous layer is made of a material for retaining an electrolyte.

摘要： A battery operated device is equipped with one or more batteries each including a positive electrode, a negative electrode, a separator, and an electrolyte in a battery case. In this battery operated device, the battery has a gas vent that is opened due to an increase in pressure inside the battery case, and is configured to dispose the gas vent at a lower position thereof when installed in the battery operated device. Therefore, the battery function is ceased due to actuation of the gas vent.

摘要： An active material layer 2 is applied on a current collector 1 so as to expose respective end parts of the current collector 1. A first active material layer non-formation part 1a at one of the end parts of the current collector 1 is formed narrower than a second active material layer non-formation part 1b at the other end part thereof. Next, a porous film 3 is formed on the current collector 1 to cover the active material layer 2. In this formation, the porous film 3 covers the edge surface of the active material layer 2 at the first non-formation part 1a while exposing a part of the second non-formation part 1b of the current collector 1.
