New solid polymer electrolyte outperforms Nafion; novel polymer folding

Green Car Congress

Researchers, led by a team from the University of Pennsylvania, have used a polymer-folding mechanism to develop a new and versatile kind of solid polymer electrolyte (SPE) that currently offers proton conductivity faster than Nafion by a factor of 2, the benchmark for fuel cell membranes. They collaborated with Kenneth B.

Self-healing polymer wrapper enables longer cycle life in silicon anodes for Li-ion batteries

Green Car Congress

Top: The stress of repeated swelling and shrinking shatters a conventional silicon electrode and its polymer binding. Bottom: An electrode coated with stretchy, self-healing polymer remains intact. (C. We want to incorporate this feature into lithium-ion batteries so they will have a long lifetime as well. Wang et al.,
