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.

Berkeley Lab, CMU team develops new class of soft, solid electrolytes for dendrite suppression; polymers and ceramics

Green Car Congress

Key to the design of these new soft, solid-electrolytes was the use of soft polymers of intrinsic microporosity (PIMs), the pores of which were filled with nanosized ceramic particles. 2020) “Universal chemomechanical design rules for solid-ion conductors to prevent dendrite formation in lithium metal batteries.”

Cornell team suggests engineered bacteria could address current limitations of energy storage technologies

Green Car Congress

If successful, this could allow storage of renewable electricity through electrochemical or enzymatic fixation of carbon dioxide and subsequent storage as carbon-based energy storage molecules including hydrocarbons and non-volatile polymers at high efficiency. At the same time, having many options also creates too many engineering choices.
