Abstract: Generally, this disclosure provides systems, devices and methods for extending charge cycle life of rechargeable batteries through the use of constrained anode fibers. A battery may include a porous anode fiber configured to produce electrons during discharge of the battery. The battery may also include and an anode current collector layer, configured to provide a conductive path to a first terminal of the battery, wherein the anode current collector layer is concentrically disposed on the anode fiber to constrain expansion of the anode fiber during charging of the battery. The porosity of the anode fiber allows for the constrained expansion to be directed radially inward, decreasing the volume of the porous regions of the anode fiber.
