POWER STORAGE DEVICE
Document Type and Number:
Japanese Patent JP2022043686
Kind Code:
A
Abstract:
To improve the adhesiveness between a current collector and a seal portion in a power storage device with a specific structure.SOLUTION: A power storage device 10 includes a positive electrode 21 having a positive electrode current collector 21a and a positive electrode active material layer 21b, a negative electrode 22 having a negative electrode current collector 22a and a negative electrode active material layer 22b, a separator 23 arranged between the positive electrode active material layer 21b and the negative electrode active material layer 22b, and a sealing portion 24 forming a closed space S for accommodating a liquid electrolyte between the positive electrode 21 and the negative electrode 22. At least one of the positive electrode current collector 21a and the negative electrode current collector 22a is an aluminum current collector whose first surface is made of aluminum to which the positive electrode active material layer 21b or the negative electrode active material layer 22b is provided. The liquid electrolyte contains a metal fluoride salt and a non-aqueous solvent containing a phosphoric acid ester.SELECTED DRAWING: Figure 1
