Abstract
Methods and systems are provided for a battery encapsulant. In one example, a method may include a battery encapsulant surrounding one or more battery cells of a vehicle battery, where the encapsulant comprises a Young Modulus between 0.05 to 0.15 GPa after being cured.
Claims20
A battery comprising:
- a plurality of battery cells, arranged and stacked to form a series of battery cell groups;
- and
- an encapsulant having a Young Modulus in a range of 0.05 to 0.15 GPa surrounding the battery cell groups.
A vehicle starter battery comprising:
- a plurality of battery cells located interior to top, bottom, and side walls, and where an encapsulant is located between the battery cells and each of the top, bottom, and side walls, and where the encapsulant comprises a Flex Modulus between 0.100 and 0.250 GPa.
A vehicle battery comprising:
- an encapsulant surrounding a plurality of battery cells arranged within the confines of top, side, and bottom walls of a battery housing, and where the encapsulant is located between the battery cells and each of the top, side, and bottom walls, and where the encapsulant comprises a Young Modulus between 0.05 to 0.10 GPa and a Flex Modulus between 0.100 to 0.250 GPa.
