Stanford's Yi Cui and colleagues have created a lithium-ion battery that alerts users to potential overheating and fire.
Stanford University scientists have developed a "smart" lithium-ion battery that gives ample warning before it overheats and bursts into flames.
The new technology is designed for conventional lithium-ion batteries now used in billions of cellphones, laptops and other electronic devices, as well as a growing number of cars and airplanes.

Device is used to monitor brain pressure in lab mice as prelude to possible use with human patients; future applications of this pressure-sensing technology could lead to touch-sensitive “skin” for prosthetic devices.
Stanford engineers have invented a wireless pressure sensor that has already been used to measure brain pressure in lab mice with brain injuries.
The underlying technology has such broad potential that it could one day be used to create skin-like materials that can sense pressure, leading to prosthetic devices with the electronic equivalent of a sense of touch.

Stanford scientists and an international research group receive funding to advance solar cells, batteries, renewable fuels and bioenergy.
The Global Climate and Energy Project (GCEP) at Stanford University has awarded $10.5 million for seven research projects designed to advance a broad range of renewable energy technologies. The funding will be shared by six Stanford research teams and an international group from the United States and Europe.

Stanford team developing gel-like padding that could help cells survive injection and heal spinal cord injuries
A team of engineers and scientists is developing a gel to help protect cells from the trauma of being injected into an injury site. The work could help speed cell-based therapies for spinal cord injuries and other types of damage.
It is a turbulent and sometimes deadly life for cells injected to heal injuries. The act of being squirted through a thin needle into the site of an injury jostles the delicate cells against each other and against the needle walls. Then, once in the site of injury, they face a biological war zone of chemicals. It's no wonder, then, that treating spinal cord injuries and other damage with injected cells has been a challenge.

A team including Stanford engineers discovers that the benefits of slow draining and charging may have been overestimated.
A comprehensive look at how tiny particles in a lithium ion battery electrode behave shows that rapid-charging the battery and using it to do high-power, rapidly draining work may not be as damaging as researchers had thought – and that the benefits of slow draining and charging may have been overestimated.

The development could lead to smaller, cheaper and more efficient rechargeable batteries.
Engineers across the globe have been racing to design smaller, cheaper and more efficient rechargeable batteries to meet the power storage needs of everything from handheld gadgets to electric cars.
In a paper published today in the journal Nature Nanotechnology, researchers at Stanford University report that they have taken a big step toward accomplishing what battery designers have been trying to do for decades – design a pure lithium anode.

A team led by Yi Cui, an associate professor of Materials Science and Engineering and at SLAC, is working to make a better battery by making the cathode of sulfur instead of today's lithium-cobalt oxide.
Tucked in a small laboratory at SLAC National Accelerator Laboratory, a team of engineers and scientists from the Stanford Institute for Materials and Energy Sciences (SIMES) is making and testing new types of lithium-ion batteries. Their goal: move beyond today's lithium-ion to create a battery five times better than those we use now.

Using high-brilliance X-rays, researchers track the process that fuel cells use to produce electricity, knowledge that will help make large-scale alternative energy power systems more practical and reliable.
Solar power and other sources of renewable energy can help combat global warming, but they have a drawback: they don't produce energy as predictably as plants powered by oil, coal or natural gas. Solar panels only produce electricity when the sun is shining, and wind turbines are only productive when the wind is brisk.
Ideally, alternative energy sources would be complemented with massive systems to store and dispense power – think batteries on steroids. Reversible fuel cells have been envisioned as one such storage solution.

Computer simulation shows how to make a crystal that would toggle like a light switch between conductive and non-conductive structures. This could lead to flexible electronic materials and, for instance, enable a cell phone to be woven into a shirt.
Do not fold, spindle or mutilate. Those instructions were once printed on punch cards that fed data to mainframe computers. Today’s smart phones process more data, but they still weren’t built for being shoved into back pockets.
In the quest to build gadgets that can survive such abuse, engineers have been testing electronic systems based on new materials that are both flexible and switchable – that is, capable of toggling between two electrical states: on-off, one-zero, the binary commands that can program all things digital.
