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 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.
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 »
Researchers develop novel battery electrolyte for lithium metal batteries
A new lithium-based electrolyte invented by Stanford University scientists could pave the way for the next generation of EVs.

New machine-learning method could supercharge EV battery development
Battery performance can make or break the EV experience, from driving range to charging time to the lifetime of the car. A team led by Stanford Professors Stefano Ermon and William Chueh has developed a machine-learning algorithm that could lead to longer-lasting, faster-charging batteries. For decades, advances in EV batteries have been limited by evaluation… Read more »
