Researchers at The University of Texas at El Paso have developed a way to 3D-print an essential battery component in nearly any shape. Their innovation could free engineers from the constraints of standard rechargeable battery sizes and allow energy storage to be built directly into the devices the batteries power.
The work, detailed in a study published in Communications Engineering, centers on gel polymer electrolytes, the material inside a battery that carries the ions (the particles that carry the electrical charge) between the electrodes—the two terminals where chemical reactions occur and electric...
