A method of forming a lithium-ion battery by spinning and a battery formed thereby are disclosed. The spinning may include electrospinning A first anode layer may be spun, followed by a first separator layer, a first cathode layer, and a second separator layer. Each layer may be spun directly onto the previously spun layer to provide a battery that does not include metal current collectors. The anode and/or cathode layers may include polyacrylonitrile (PAN) fibers. To render the anode and cathode layers conductive, they may be carbonized using a heat source (e.g., a laser). The disclosed method may allow for the incorporation of high capacity materials, such as sulfur and/or silicon, in the electrode active materials.
