MIT engineers create 2D polymer that self-assembles into sheets

Green Car Congress

Using a novel polymerization process, MIT chemical engineers have created a new two-dimensional polymer that self-assembles into sheets, unlike all other polymers which form one-dimensional chains. Until now, scientists had believed it was impossible to induce polymers to form 2D sheets. —Michael Strano.

Mullen to begin testing Linghang solid-state polymer battery technology in vehicles on US roads in Q4 2023

Green Car Congress

Mullen Automotive, an emerging EV manufacturer, has integrated solid-state polymer battery technology into Mullen’s commercial Class 1 EV cargo van program. It is expected that the solid-state polymer technology will deliver more than 200 miles of range on a full charge for the Mullen Class 1 EV cargo van.

Berkeley Lab conductive polymer coating could enhance performance of EV batteries

Green Car Congress

Scientists at Lawrence Berkeley National Laboratory (Berkeley Lab) have developed a conductive polymer coating—called HOS-PFM—that could enable longer lasting, more powerful lithium-ion batteries for electric vehicles. At room temperature (20 ˚C), alkyl end-chains on the PFM polymer chain limit the movement of lithium ions.

Researchers use self-healing composite polymer binder to boost performance of silicon anodes

Green Car Congress

Researchers at the Japan Advanced Institute of Science and Technology have improved the performance of silicon anodes in LIBs using a self-healing composite polymer binder for the silicon particles. The composite polymer structure holds the silicon particles together like a net and prevents them from rupturing.

ORNL team develops 3D interconnected polymer/ceramic composite as a thin film solid electrolyte

Green Car Congress

Oak Ridge National Laboratory researchers have developed a thin-film, highly conductive solid-state electrolyte made of a polymer and ceramic-based composite for lithium metal batteries. There are two classes of solid electrolytes, inorganic oxide- or sulfide-based electrolytes and polymer-based electrolytes. —Palmer et al.

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. Trigg, then a doctoral student in her lab.
