Stanford study: 100% renewable US grid is feasible and reliable
How many times this week have you read that renewable energy is unreliable, and will never be able to completely replace fossil fuels on the electrical grid? Well, there is at least one group of scientists who don’t agree. A study led by Stanford University Professor Mark Jacobson has found that a US energy system… Read more »
Stanford researchers demonstrate major advance in dynamic charging
Stanford engineers say they have taken a big step toward a practical system for dynamic charging, which would allow EVs to recharge while hurtling down the highway. Stanford Professor Shanhui Fan has been working on dynamic charging for some time. In 2012, he and his team published a description of a dynamic system, which they… Read more »
Stanford team develops Li-metal anodes
Lithium-metal anodes are the favored solution for next-generation Li-air or Li-sulfur batteries for various reasons, including their high specific capacity (theoretically tenfold higher than graphite). However, safety issues resulting from dendrite formation and instability caused by volume expansion have slowed the development of commercially viable solutions. In “Composite lithium metal anode by melt infusion of… Read more »
Stanford team improves potential of solid-state electrolytes by enhancing ionic conductivity
Solid-state electrolytes’ potential advantages in energy density and safety compared with conventional liquid electrolytes have made them the hottest topic in the battery world. However, there are several challenges to be overcome, including the low mobility of lithium ions in solid electrolytes. Now, a team of Stanford researchers have used ceramic nanowire fillers to enhance… Read more »
Stanford team develops stable lithium anode
Are the knights of nanotechnology closing in on the Grail at last? A team of researchers at Stanford University claim that they are, and have chronicled their deeds in the journal Nature Nanotechnology. The valiant engineers report that they have designed a pure lithium anode. “Of all the materials that one might use in an… Read more »
Stanford researchers design a wireless system that could charge EVs on the go
The Stanford team’s system can transfer 10 kW of power over a distance of 6.5 feet – enough to charge a car moving at highway speeds – and has an efficiency of 97 percent.
Amprius supplies batteries for solar cars competing in cross-Australia race
Amprius Technologies, maker of the Silicon Anode Platform for lithium-ion batteries, is supplying battery cells to the Astrum solar car, which a team from the University of Michigan will race in the Bridgestone World Solar Challenge in October. The Bridgestone World Solar Challenge requires teams to design, develop and pilot a solar-powered vehicle along a… Read more »
