Dendrite-Free Rechargable Batteries (image) DOE/Pacific Northwest National Laboratory Share Print E-Mail Caption Pacific Northwest National Laboratory has developed a new electrolyte that allows lithium-sulfur, lithium-metal and lithium-air batteries to operate well without growing dendrites, tiny pin-like fibers that short-circuit rechargeable batteries. Shown here are two scanning electron microscope images that illustrate how a traditional electrolyte can cause dendrite growth (a, left), while PNNL's new electrolyte instead causes the growth of smooth nodules that don't short-circuit batteries (b, right).
