Towards better batteries and fuel cells with dispersibility estimation for carbon electrode slurries

Updated: 2023-08-24 16:18:32

Carbon slurries, which consist of a suspension of carbon particles in a solvent, are used to mass-produce battery electrodes. However, there are no adequate methods to evaluate whether the particles are uniformly dispersed in the slurry during the manufacturing process. In a recent study, researchers used an innovative approach, combining viscosity and electrochemical impedance measurements, to accurately assess the dispersibility of slurries, opening doors to enhanced electric vehicles and fuel cell batteries.

Chloride ions from seawater eyed as possible lithium replacement in batteries of the future

Updated: 2023-08-10 23:01:12

Sodium, Potassium and zinc have all been promising contenders for lithium's place in rechargeable batteries of the future, but researchers have added an unusual and more abundant competitor to the mix: chloride, the richest negatively charged ions in seawater. Xiaowei Teng, the James H. Manning professor of Chemical Engineering at WPI, has discovered a new redox chemistry empowered by chloride ions for the development of seawater green batteries.
