Researchers develop ultralow content binder for high-performance silicon anodes

Green Car Congress

The new 3D-crosslinked binder (LiCMC-TA) is synthesized using the partially lithiated Carboxymethyl Cellulose Sodium (LiCMC) as a skeleton structure and Tannic Acid (TA) as cross-linker via multiple hydrogen bonding interactions. The highly branched TA is introduced to construct a network of multiple hydrogen bonds. Tang et al.

Researchers identify key bottleneck in MgH2 solid-state hydrogen storage desorption

Green Car Congress

Furthermore, the material's complex hydrogen migration and desorption, which result in sluggish dehydrogenation kinetics, have stymied its commercial application. The Mg–H bond analyses by the crystal orbital Hamilton population method indicate that the Mg–H bond strength decreases along the dehydrogenation process.

Researchers designs new deep eutectic solvent to recover valuable elements from spent LNCM batteries

Green Car Congress

DESs, first proposed by Abbott in 2003, are a class of low eutectic mixtures comprising a combination of a hydrogen-bond acceptor (HBA) and a hydrogen-bond donor (HBD) through intermolecular hydrogen bonding, which have a melting point lower than that of either constituent.

New photocatalytic system converts carbon dioxide to valuable fuel more efficiently than natural photosynthesis

Green Car Congress

Although artificial photocatalytic cycles have been shown to operate with higher intrinsic efficiency, the low selectivity and stability in water for carbon dioxide reduction have hampered their practical applications. It mimics the structure of a purple bacteria’s light-harvesting chromatophores (i.e.

Fraunhofer Researchers Develop Process for Laser Forming and Bonding of Fiber-Reinforced Composites; Marine, Automotive and Aerospace Applications

Green Car Congress

Components made of fiber-reinforced straps are bonded with an infrared laser. Researchers at Fraunhofer-Gesellschaft in Germany have developed a process that crafts and bonds fiber-reinforced composites with lasers. Click to enlarge. Fraunhofer will demonstrate the process at the JEC Composites Show 2010 in Paris, 13-15 April.
