Flexible Wire Type Lithium Battery

Flexible lithium metal batteries with high theoretical energy density are highly desired to power up various wearable electronics. The flexibility of current device is limited by either stacking device configuration or utilization of fragile current collectors (Cu and Al foil) and bulky lithium anode.

This technology involves the designing of omnidirectionally flexible wire-type lithium battery via scalable process. The cell achieves both remarkable device flexibility (flexing radius = 1mm) and high electrochemical performance (> 400 cycles’ charge/discharge at 0.2 C).

This technology broadens the applications of flexible lithium batteries such as integration with bendable/foldable smartphones or woven into breathable electronic textiles.
