  • Patent number: 9899649
    Abstract: A non-aqueous electrolyte secondary battery, when using an aqueous binder as a binder for a negative electrode active material, effectively exhausts the gas generated from an electrode, and thus, even when using it for a long period of time, a decrease in battery capacity is low. The non-aqueous electrolyte secondary battery includes a positive electrode active material layer on a surface of a positive electrode current collector, a negative electrode active material layer comprising an aqueous binder on a surface of a negative electrode current collector, a separator for maintaining an electrolytic solution, and a gas releasing means for releasing a gas generated within the power generating element to an extra space inside of the outer casing, and in which the ratio value of a volume of the extra space to a volume of pores included in the power generating element is 0.5 to 1.0.

  • Publication number: 20090037076
    Abstract: In a method of injecting a fluid with a liquid-to-gas phase transition, the fluid is injected via a specified path of a change in an isobaric specific heat capacity per volume [Cp/V] of the fluid, the specified path leading from a temperature-pressure condition (i) to a temperature-pressure condition (ii). The condition (i) realizes an equality [Cp/V]=[Cp/V]L, where [Cp/V]L denotes an isobaric specific heat capacity per volume of the fluid in the liquid phase. The temperature-pressure condition (ii) realizes an equality [Cp/V]=[Cp/V]J, where [Cp/V]J denotes an isobaric specific heat capacity per volume of the fluid at timing of injection. The value [Cp/V]J is less than the value [Cp/V]L and included in a temperature-pressure region extending in close proximity to a high-temperature side of a temperature-pressure region corresponding to a temperature-pressure condition (iii) that realizes an isobaric specific heat capacity per volume [Cp/V]C greater than the value [Cp/V]L.
