摘要

According to one embodiment, a secondary battery is provided. The separator includes a porous self-supporting film, a solid electrolyte layer, and a first binder. The solid electrolyte layer is provided on one main surface of the porous self-supporting film. The porous self-supported film and the solid electrolyte layer are adhered with the first binder. The first binder exists on both of the one main surface and another main surface of the porous self-supporting film. The solid electrolyte layer includes solid electrolyte particles and a second binder. The solid electrolyte particles have alkali metal ions conductivity. The polymeric material of the second bonder is a same as the polymeric material of the first material.

說明書

The positive electrode-side connector 341 is provided with a through-hole. By inserting the other end of the positive electrode-side lead 22 into the though-hole, the positive electrode-side connector 341 and the positive electrode-side lead 22 become electrically connected. The negative electrode-side connector 342 is provided with a through-hole. By inserting the other end of the negative electrode-side lead 23 into the though-hole, the negative electrode-side connector 342 and the negative electrode-side lead 23 become electrically connected.

The thermistor 343 is fixed to one main surface of the printed wiring board 34. The thermistor 343 detects the temperature of each single-battery 100 and transmits detection signals to the protective circuit 344.

The external power distribution terminal 347 is fixed to the other main surface of the printed wiring board 34. The external power distribution terminal 347 is electrically connected to device(s) that exists outside the battery pack 300.
