A team of researchers from UC Irvine and four national laboratories has fabricated a cobalt-free cathode for lithium-ion batteries. The researchers relied on doping using HE-LMNO and magnesium, titanium, manganese, molybdenum and niobium inside the structure to fabricate a high-nickel cathode. “Through a technique we refer to as ‘high-entropy doping,’ we were able to successfully… Read more »

Oil wells could soon be pumping lithium in Alberta
Everybody loves lithium, but mining it does have an environmental footprint. Everybody (around here) hates oil, which has a much bigger footprint. But what if I told you that there’s a way to extract lithium from existing oil wells, and that it’s not only greener than other lithium extraction methods, but could even clean up… Read more »
Designing a hardware-in-the-loop simulation test system for an EV startup
Sponsored by Pickering interfaces A complete physical HIL simulation system based around modular PXI switching and simulation modules Imagine the challenge. You are working for an electric vehicle (EV) startup, designing the Hardware-in-the-Loop Simulation (HILS) test system. Everything is new – the hardware, the software, the tools, the testers and the test code. Yet, the… Read more »
