UH, Toyota researchers develop new cathode and electrolyte for high-power Mg battery rivaling Li-ion

Green Car Congress

Magnesium batteries have long been considered a potentially safer and less expensive alternative to lithium-ion batteries, but previous versions have been severely limited in the power they delivered. The combination affords a Mg battery that delivers a specific power of up to 30.4?kW?kg —Dong et al.

Tesla Giga Texas is stocking up on 4680 structural battery packs

Teslarati

Model Ys are being produced in Texas, but only some of them are equipped with 4680 structural battery packs. Those that are not equipped with 4680 batteries are fitted with the company’s 2170 cells, similar to the Model Ys produced in the Fremont Factory. Credit: Joe Tegtmeyer/Twitter.

Tesla Model Y test body with space for structural battery pack sighted in Giga Texas

Teslarati

Tesla may be quite silent about the progress of its 4680 cells and structural battery packs, but recent sightings of Model Y test bodies in Gigafactory Texas suggest that the rollout of the innovative technology may be closer than expected. Watch Joe Tegtmeyer’s recent drone flyover of the Giga Texas site in the video below.

New organic cathode for high performance solid-state sodium-ion battery

Green Car Congress

Solid-state sodium-ion batteries are safer than conventional lithium-ion batteries, which pose a risk of fire and explosions, but their performance has been too weak to offset the safety advantages. Yao also is a principal investigator at the Texas Center for Superconductivity at UH. —Yan Yao. 2019.03.017.

Researchers devise electrode architectures to prevent dendrite formation in solid-state batteries

Green Car Congress

Interest in higher energy-density batteries that pair alkali metal electrodes with solid electrolytes is high; however, such batteries have been plagued by a tendency for dendrites to form on one of the electrodes, eventually bridging the electrolyte and shorting out the battery cell.
