New conductive polymer addresses volumetric change issue with silicon anodes for Li-ion batteries; high-capacity and longer cycle life reported

Green Car Congress

A team of scientists at the US Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) has developed new polyfluorene-based conductive polymers that address the long-standing issue of volumetric change in high-capacity silicon (Si) anodes for Li-ion batteries. to determine their key electronic properties.

Liquid microscopy technique reveals new problem with lithium-oxygen batteries; lithium peroxide in electrolyte

Green Car Congress

One of the reasons for this loss of power is that a byproduct of the chemical reactions that take place inside the battery—lithium peroxide (Li 2 O 2 —builds up on the electrodes of the battery. The growth of Li 2 O 2 isolated in the electrolyte exhibits O 2 - diffusion-limited kinetics. —He et al.

Berkeley Lab researchers shed light on how lithium-rich cathodes work, opening the door to higher capacity batteries

Green Car Congress

The traditional design paradigm for Li-ion battery cathodes has been to create compounds in which the amount of extractable Li + is well balanced with an oxidizable transition metal (TM) species (such as Mn, Fe, Co or Ni) to provide the charge-compensating electrons, all contained in an oxide or sulfide host. O 2 , Li 2 Ru 0.5

APRA-E awards WUSTL $2M to develop predictive battery management system for plug-in vehicles; targeting more efficient use

Green Car Congress

Louis (WUSTL) will receive $2 million from the US Department of Energy’s ARPA-E to design a predictive battery management system for lithium-ion batteries to guarantee their longevity, safety and performance. If Li-ion batteries are charged too quickly, they can heat up and may explode. —Venkat Subramanian. Resources.
