    摘要： To provide a negative electrode for a non-aqueous electrolyte secondary battery that can be produced even without performing a heat treatment at a high temperature such as 2,000°C or higher and can have the discharge capacity and the cycle characteristics (capacity retention) further increased.
    The negative electrode for a non-aqueous electrolyte secondary battery according to the invention has a configuration in which a negative electrode active material layer containing a negative electrode material and a binder is formed on the surface of a current collector. Further, the negative electrode material has a core portion including carbonaceous negative electrode active material particles; and a shell portion including a polyimide and silicon-based negative electrode active material particles and/or tin-based negative electrode active material particles. Here, there is a feature that the content of the silicon-based negative electrode active material particles and/or tin-based negative electrode active material particles with respect to 100% by mass of the content of the carbonaceous negative electrode active material particles is 2% to 20% by mass. Furthermore, there is a feature that the binder is formed of a hydrophilic unit and a hydrophobic unit bonded together.

    摘要： Provided is a secondary battery with which any temperature increase in a power generation element of the battery can be minimized even when a conductor enters the power generation element. A secondary battery (1) comprises: a power generation element (100) having a unit cell layer (14b) in which a positive electrode (12), a separator (15), and a negative electrode (13) are stacked in the stated order; an electroconductive member (32) disposed on one outward side of the power generation element (100) with an insulation member (31) interposed therebetween; a lead wire (33) connecting the electroconductive member (32) with a negative electrode tab (17a); a coil (41) that detects whether or not current is flowing to the lead wire (33); and an external discharge safety circuit (36) provided with a switch (42) that short-circuits a positive electrode tab (16a) and the negative electrode tab (17a) outside the power generation element (100) when the coil (41) has detected current.
