Title:
NONAQUEOUS ELECTROLYTE SECONDARY BATTERY
Document Type and Number:
Japanese Patent JP2017076484
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a nonaqueous electrolyte secondary battery which is high in resistance against metallic lithium precipitation when repeatedly charged and discharged.SOLUTION: A nonaqueous electrolyte secondary battery disclosed herein comprises: an electrode body having a positive electrode 50 including a positive electrode active material layer 54, a negative electrode 60, and a separator 70 interposed between the positive and negative electrodes; a nonaqueous electrolyte; and a case in which the electrode body and the nonaqueous electrolyte are encased. The separator 70 has a heat-resistant layer 72; and the heat-resistant layer 72 includes an inorganic phosphate which is an acid-capturing material. The heat-resistant layer 72 is opposed to the positive electrode active material layer 54.SELECTED DRAWING: Figure 3
