Stanford researchers make rechargeable batteries that store six times more charge

Serendipitous discovery: "It took us about at least a year to really realize what was going on"

01-Sep-2021

An international team of researchers led by Stanford University have developed rechargeable batteries that can store up to six times more charge than ones that are currently commercially available. The advance, detailed in a new paper published Aug. 25 in the journalNature, could accelerate the ...

First closeups of how a lithium-metal electrode ages

Scientists have documented a process that makes these next-gen batteries lose charge - and eventually some of their capacity for storing energy - even when a device is turned off

26-Mar-2021

The same process that drains the battery of your cell phone even when it's turned off is even more of a problem for lithium-metal batteries, which are being developed for the next generation of smaller, lighter electronic devices, far-ranging electric vehicles and other uses. Now scientists at ...

Controlling chemical catalysts with sculpted light

This work could inform more efficient – and potentially new – forms of catalysis

25-Jan-2021

Like a person breaking up a cat fight, the role of catalysts in a chemical reaction is to hurry up the process - and come out of it intact. And, just as not every house in a neighborhood has someone willing to intervene in such a battle, not every part of a catalyst participates in the reaction. ...

Predicting the slow death of lithium-ion batteries

In electric cars, the new technology could improve driving range estimates and prolong battery life

17-Sep-2020

Batteries fade as they age, slowly losing power and storage capacity. As in people, aging plays out differently from one battery to another, and it's next to impossible to measure or model all of the interacting mechanisms that contribute to decline. As a result, most of the systems used to ...

Researchers design efficient low-cost system for producing power at night

Rooftop radiative cooling system could provide lighting power when solar energy is unavailable

18-Aug-2020

Researchers have designed an off-grid, low-cost modular energy source that can efficiently produce power at night. The system uses commercially available technology and could eventually help meet the need for nighttime lighting in urban areas or provide lighting in developing countries. Although ...

Scientists home in on pairs of atoms that boost a catalyst's activity

They discovered that the messy environment of a chemical reaction can actually change the shape of a catalytic nanoparticle in a way that makes it more active

24-Jun-2020

Replacing the expensive metals that break down exhaust gases in catalytic converters with cheaper, more effective materials is a top priority for scientists, for both economic and environmental reasons. Catalysts are required to perform chemical reactions that would otherwise not happen, such as ...

Machine learning could speed the arrival of ultra-fast-charging electric car

21-Feb-2020

Battery performance can make or break the electric vehicle experience, from driving range to charging time to the lifetime of the car. Now, artificial intelligence has made dreams like recharging an EV in the time it takes to stop at a gas station a more likely reality, and could help improve ...

New route to carbon-neutral fuels from carbon dioxide discovered

18-Sep-2019

If the idea of flying on battery-powered commercial jets makes you nervous, you can relax a little. Researchers have discovered a practical starting point for converting carbon dioxide into sustainable liquid fuels, including fuels for heavier modes of transportation that may prove very difficult ...

Tiny light detectors work like gecko ears

02-Nov-2018

Geckos and many other animals have heads that are too small to triangulate the location of noises the way we do, with widely spaced ears. Instead, they have a tiny tunnel through their heads that measures the way incoming sound waves bounce around to figure out which direction they came ...

Efficient electrochemical cells for CO2 conversion

29-Oct-2018

Scientists at Stanford University have developed electrochemical cells that convert carbon monoxide (CO) derived from CO2 into commercially viable compounds more effectively and efficiently than existing technologies. Their research provides a new strategy for capturing CO2 and converting it into ...
