New 3D, self-supported electrode could pave the way for large-scale hydrogen production

The numerous submicron channels on the surface of the honeycomb alloy, a large amount of nickel element migrates to the surface and transforms into another highly-active species, which greatly promotes oxygen production. As the method developed in this work can be readily scaled up, it may pave the way for fabricating more efficient, foam, metal-based materials for large-scale hydrogen production.

New LiMn2O4 electrode could pave the way for electrochemical recovery of lithium from brine

Lithium has been dubbed the ‘energy metal of the 21st century’. Most of the world's lithium is now extracted from oil well brines, salt-lake brines and geothermal waters. However, increasing the efficiency of the brine lithium recovery process remains a key goal for researchers working in the field. This study describes a new approach using a specially-designed version of a LiMn2O4 electrode, which has the potential to address this issue.
