A new stretchable hydrogel battery can withstand extreme conditions and still operate effectively, scientists say.

The battery built by his team endured 500 complete charge cycles—about as many as the batteries in most smartphones are ...

It survived punctures, razor cuts, and a full month of abuse — without a drop spilled. At first glance, it looks like a ...

Once the salt melts (usually from a pyrotechnic charge), the battery can produce a lot of energy for a relatively short period of time thanks to the high ionic conductivity of the electrolyte ...

A team led by UC Berkley scientists have developed a flexible lithium-ion battery that withstands stabs, bends, and stretches ...

A team of chemists found a way to see into battery interfaces — tight, tricky spots buried deep inside the cell have long frustrated battery designers.

These take advantage of the fact that the torpedo’s forward motion can force fresh salt water through the battery, continually replenishing the electrolyte. This also serves to cool the battery ...

“The freeze-thaw phenomenon is possible because the battery’s electrolyte is molten salt – a molecular cousin of ordinary table salt. The material is liquid at higher temperatures but solid ...

A pioneering lithium-ion battery that can stretch, self-repair after being cut, and maintain power output under extreme ...

Using X-ray computed tomography, researchers reconstruct three-dimensional electrodes to improve understanding of electrolyte ...
