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. —Prof.

Researchers show that inherent lithium ions in bioderived borate polymer enhance extreme fast charging capability in graphite anodes

Green Car Congress

The binder material—a novel aqueous borate type bio-based polymer with inherent Li + ions designed as an SEI forming binder for graphite—leads to improved diffusion of desolvated Li + ions across the solid electrolyte interface (SEI) and within the anode material and yields high conductivity, low impedance, and good stability.

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.
