Weakness is strength for this low-temperature battery

Weakness is strength for this low-temperature battery

February 25, 2021

Nanoengineers at the University of California San Diego have discovered new fundamental insights for developing lithium metal batteries that perform well at ultra-low temperatures; mainly, that the weaker the electrolyte holds on to lithium ions, the better. By using such a weakly binding electrolyte, the researchers developed a lithium metal battery that can be repeatedly recharged at temperatures as low as -60 degrees Celsius—a first in the field.

Human-centered mobility and transportation options for disadvantaged communities is the goal of new partnership

Human-centered mobility and transportation options for disadvantaged communities is the goal of new partnership

February 24, 2021

The University of California San Diego is teaming up with several community-based organizations and the San Diego Association of Governments to improve access to transportation for the county’s low-income and underserved neighborhoods. The team is adopting a human-centered design approach to their work to try and repair the harm done by car-oriented transportation policies of the past.    Full Story

Cancer is a genetic disease that can lay waste to DNA. In many cases, error correction mechanisms mutate, removing the quality control circuits that maintain genes, setting the stage for more mutations. Full Story


New material is next step toward stable high-voltage long-life solid-state sodium-ion batteries

New material is next step toward stable high-voltage long-life solid-state sodium-ion batteries

February 23, 2021

A team of researchers designed and manufactured a new sodium-ion conductor for solid-state sodium-ion batteries that is stable when incorporated into higher-voltage oxide cathodes. This new solid electrolyte could dramatically improve the efficiency and lifespan of this class of batteries. A proof of concept battery built with the new material lasted over 1000 cycles while retaining 89.3% of its capacity--a performance unmatched by other solid-state sodium batteries to date.    Full Story
