Title:
非水電解液二次電池
Document Type and Number:
Japanese Patent JP6892222
Kind Code:
B2
Abstract:
A nonaqueous electrolyte secondary battery includes a fiber layer, which contains fiber composed of a synthetic resin, between a separator and a positive electrode and/or between the separator and a negative electrode. The fiber layer contains at least PVDF and PTFE as components of the synthetic resin configuring the fiber. The PVDF and the PTFE both have an average molecular weight of equal to or greater than 200,000 and equal to or less than 2,000,000. In the components of the synthetic resin configuring the fiber, the content of PVDF is greater than the content of PTFE, and the content of PTFE is equal to or less than 45% by mass with respect to the total amount of the components of the synthetic resin.
