Progress Toward Fast-charging Lithium-metal Batteries

February 9, 2023

Engineers report progress toward lithium-metal batteries that charge fast – as fast as an hour. This fast charging is thanks to lithium metal crystals that can be seeded and grown quickly into dense layers of uniform lithium metal that lack battery-performance-degrading spikes called dendrites.

Ultrasound device improves charge time and run time in lithium batteries

February 18, 2020

Researchers at the University of California San Diego developed an ultrasound-emitting device that brings lithium metal batteries, or LMBs, one step closer to commercial viability. Although the research team focused on LMBs, the device can be used in any battery, regardless of chemistry.

A flexible screen-printed rechargeable battery with up to 10 times more power than state of the art

December 7, 2020

A team of researchers has developed a flexible, rechargeable silver oxide-zinc battery with a five to 10 times greater areal energy density than state of the art. The battery also is easier to manufacture; while most flexible batteries need to be manufactured in sterile conditions, under vacuum, thi

‘Spillway’ for Electrons Could Keep Lithium Metal Batteries from Catching Fire

March 12, 2020

UC San Diego nanoengineers developed a safety feature that prevents lithium metal batteries from rapidly overheating and catching fire in case of an internal short circuit. The clever tweak does not prevent battery failure, but rather provides advance warning of failure and makes it much safer.

Recycling and Reusing Worn Cathodes to Make New Lithium Ion Batteries

January 25, 2018

…from spent lithium ion batteries and makes them work just as good as new. The process involves harvesting the degraded cathode particles from a used battery and then boiling and heat treating them. Researchers built new batteries using the regenerated cathodes. Charge storage capacity, charging time and battery lifetime were…

UC San Diego Part of New DOE Consortium to Revolutionize Electric Car Battery Performance

August 5, 2016

…to almost triple the energy packed in electric car batteries and make them smaller, lighter and less expensive. This would allow manufacturers to make more affordable electric vehicles that can travel two to three times farther.

Using Batteries to Cut Utility Costs

March 21, 2017

CNS postdoctoral researcher Alper Sinan Akyurek and CSE professor Tajana Rosing developed an algorithm for controlling batteries that can decrease the utility cost of an actual building by up to 50 percent compared to a building powered without the use of batteries.

Researchers Determine Optimum Pressure to Improve the Performance of Lithium Metal Batteries

October 18, 2021

A team of materials scientists and chemists has determined the proper stack pressure that lithium metal batteries, or LMBs, need to be subjected to during battery operation in order to produce optimal performance.

Researchers Transform an Amorphous Solid Into a New Lithium-Ion Battery Material

May 2, 2022

Researchers at UC San Diego and Boise State University have developed a new approach to making novel lithium-ion battery materials. The approach transforms a non-crystalline material into a crystalline anode material with exceptional battery properties—by cycling it with lithium.

San Diego Supercomputer Center Replaces Lead-Acid Backup Batteries with Green Alternative

April 22, 2022

Urban Electric Power installed rechargeable alkaline battery technology at the San Diego Supercomputer Center, replacing 20,000 pounds of toxic lead-acid batteries with a safer, environmentally friendly and cost-effective alternative, and more than doubling the available battery backup electricity.
