Berkeley Lab team designs active polyelectrolyte binder that allows for a doubling in capacity of conventional Li-sulfur battery

Green Car Congress

A team of researchers led by scientists at the US Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) have designed an active polyelectrolyte binder (PEB) that actively regulates key ion transport processes within a lithium-sulfur battery, and have also shown how it functions on a molecular level.

DOE JCESR team significantly improves Li-S performance under lean electrolyte with soft swellable gel

Green Car Congress

Li-sulfur batteries are looked to as a likely next-generation higher energy density energy storage system due to the high theoretical capacity, low cost and high earth abundance of sulfur. A paper on their work is published in the ACS journal Nano Letters. A paper on their work is published in the ACS journal Nano Letters.

PEM fuel cell X-ray CT study details effects of temperature and moisture on performance

Green Car Congress

Polymer electrolyte membrane (PEM) fuel cells require precise temperature and moisture controls to be at their best. The performance of polymer-electrolyte fuel cells (PEFCs) and other multiphase flow technologies is significantly dependent on liquid-water management. Credit: Berkeley Lab).

PNNL team finds electrolyte additive enables fast charging, stable cycling Li-metal batteries

Green Car Congress

Researchers at Pacific Northwest National Laboratory (PNNL) have found that adding a small, optimal amount (0.05M) of LiPF 6 (lithium hexafluorophosphate) as an additive in LiTFSI–LiBOB dual-salt/carbonate-solvent-based electrolytes significantly enhances the charging capability and cycling stability of Li metal batteries.
