Stanford researchers develop new electrolysis system to split seawater into hydrogen and oxygen

Green Car Congress

Hongjie Dai and his research lab at Stanford University have developed a prototype that can generate hydrogen fuel from seawater. However, grid-scale freshwater electrolysis would put a heavy strain on vital water resources. Image credit: Courtesy of H. Dai, Yun Kuang, Michael Kenney). to 1 A/cm 2 ) over 1,000 h. —Hongjie Dai.

Ultrathin transition metal silicate nanosheet cathode material for Li-ion batteries supports reversible two-lithium-ion capacity

Green Car Congress

Charge and discharge profile of first and second cycles of Li 2 MnSiO 4 samples measured at 45 °C at 0.02C rate. Researchers from Tohoku University, Japan, have developed novel ultrathin Li 2 MnSiO 4 nanosheets for use as a cathode material in lithium-ion batteries. The Li/Li 2 MSiO 4 cells were cycled between 1.5
