Abstract
A constrained, wound lithium-ion battery cell with an internal fuse component that exhibits significant improvements in terms of life-cycle times is provided. Disclosed herein are lithium-ion battery structures and configurations utilizing at least one thin metallized film current collector that provides safety features with low thermal runaway potential, low internal resistance, with a simplified manner of providing external electrical conductivity simultaneously. The provision of a highly constrained and wound structure thereof unexpectedly allows for extended charge/discharge cycle life that is significantly improved in comparison with previous wound lithium-ion battery devices. A range of shear and compression forces accords such results, with such forces permissible through various pathways, including winding curvatures, number of windings within the cell housing, hardness of housing, and structural geometries therein. Encompassed herein is also a method of providing long cycle life results for such specific devices.
