ARPA-E awarding $39M to 16 projects to grow the domestic critical minerals supply chain

Green Car Congress

The selected projects, led by universities, national laboratories, and the private sector aim to develop commercially scalable technologies that will enable greater domestic supplies of copper, nickel, lithium, cobalt, rare earth elements, and other critical elements. Feedstocks will include Li/Ni/Ca/Mg-rich igneous and sedimentary minerals.

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. Negatively charged chloride in seawater salt can corrode the anode, however, limiting the system’s lifespan. Image credit: Courtesy of H. Dai, Yun Kuang, Michael Kenney). to 1 A/cm 2 ) over 1,000 h.

EnerDel Teams With Nissan on Electrolyte Research at Argonne Lab

Green Car Congress

Both EnerDel and AESC, Nissan’s Li-ion JV, work with that chemistry. Cells with these new silane electrolytes exhibit long calendar life; they show no impedance rise after aging at 80% state of charge and 55 °C for one year. The work will focus specifically on the Manganese spinel system, according to Dr. Amine. O 2 material.

U Michigan study finds cracking in Li-ion batteries speeds up EV charging

Green Car Congress

Rather than being solely detrimental, cracks in the cathodes of lithium-ion batteries reduce battery charge time, according to research done at the University of Michigan. Polycrystalline Li(Ni,Mn,Co)O 2 (NMC) secondary particles are the most common cathode materials for Li-ion batteries. —Min et al.
