Abstract
Battery cell 1 in the present invention includes, within flexible outer case 10, an electrolyte solution, and battery assembly 4 in which positive electrodes 6 and negative electrodes 7 are alternately laminated so as to sandwich separators 8 therebetween. Battery cell 1 includes positive electrode terminal 2 that has one end electrically connected with positive electrodes 6 and that has the other end which extends to outside of outer case 10, and negative electrode terminal 3 that has one end electrically connected with negative electrodes 7 and that has the other end that extends outside outer case 10. In battery assembly 4, fixation members 5 are provided on a pair of opposite lateral surfaces as viewed in a laminating direction of positive electrodes 6 and negative electrodes 7.
Claims9
A battery cell comprising:
- a battery assembly that is contained within a flexible outer case and in which a positive electrode and a negative electrode are alternately laminated so as to sandwich a separator therebetween;
- an electrolyte solution that is contained within said outer case;
- a positive electrode terminal that has one end electrically connected with said positive electrode and that has the other end which extends to outside of said outer case;
- a negative electrode terminal that has one end electrically connected with said negative electrode and that has the other end which extends to outside of said outer case;
- and
- fixation members that are respectively provided on a pair of opposite lateral surfaces of said battery assembly as viewed from above in a laminating direction of said positive electrode and said negative electrode.
