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 »

LG Energy Solution hires AI and data science expert to ramp up smart factories

LG Energy Solution (LGES) has selected Dr. Peter Kyungsuk Pyun for its newly created Chief Digital Officer (CDO) position. “Based on his accumulated experience in world-renowned firms, we expect LGES to take a further step forward in battery manufacturing processes by utilizing AI and big-data technology,” said an LGES spokesperson.

New Cryo-EM battery research tool produces image of SEI layer on lithium metal anode

Scientists from the Department of Energy’s SLAC National Accelerator Laboratory and Stanford University have used cryogenic electron microscopy, or cryo-EM, to produce high-resolution images of the solid-electrolyte interphase (SEI) layer that forms on lithium metal anodes in an approach that may improve lithium metal battery design. The scientists developed a way of collecting the SEI… Read more »

New paper shows atomic-scale closeups of how a lithium-metal electrode ages

Lithium-metal batteries, which use anodes made of lithium metal rather than graphite, could offer great improvements in energy density and weight. The DOE’s Battery 500 Consortium has set a goal of developing lithium-metal EV batteries with triple the energy density of today’s Li-ion cells. Now scientists at Stanford University and the SLAC National Accelerator Laboratory… Read more »

Machine learning could lead to durable fast-charging batteries

Scientists at Stanford University are harnessing machine learning (ML) to design better batteries. In addition to using ML to speed up scientific analysis by looking for patterns in data, the researchers combined it with knowledge gained from experiments and equations guided by physics to discover and explain a process that shortens the lifetimes of fast-charging… Read more »
