Spray-coated electrodes could create greener, cheaper batteries

A research team led by Worcester Polytechnic Institute, Worcester, Mass., found that by ditching toxic solvents, a new dry-coating process could make batteries more sustainable and cut manufacturing costs by 15% and energy use by 47%. It could also be faster-charging than today’s electrodes.

One Minute Mentor: Gas nitriding equipment

Gas nitriding and nitrocarburizing can be processed in horizontal or vertical chamber furnaces with refractory insulation. However, to allow a quick change of the atmosphere and to avoid influences resulting from previous processes in the same furnace, retort furnaces are preferred. To enable an acceptable production capacity, large vertical retort furnaces are used. The figure […]
