Tesla leases huge space in Shanghai for store and service center

Teslarati

The new site is expected to open in mid-2024 in Xin Park, and the news comes after Tesla last year announced plans to close select stores in China in an attempt to restrategize. Currently, Tesla has around 300 stores across China. Tesla exec shares insights on Giga Shanghai’s 2M production milestone What are your thoughts?

Researchers observe hydrogen-oxygen reaction in ceria fuel cell; insights may improve efficiency

Green Car Congress

The arrow shows the fuel cell storing electricity during the daytime when the water molecule (left) lands its oxygen atom and surrenders two hydrogen atoms (blue balls at end of arrow). The two blue balls would pick up an oxygen atom and release the electricity they stored. The blue balls are hydrogen atoms.

SLAC, MIT, TRI researchers advance machine learning to accelerate battery development; insights on fast-charging

Green Car Congress

An animation shows two contrasting views of how electrode particles release their stored lithium ions during battery charging. Until now, scientists had assumed that the differences between particles were insignificant and that their ability to store and release ions was limited by how fast lithium could move inside the particles, Kang said.

IIT, Argonne team designs Li2O-based Li-air battery with solid electrolyte; four-electron reaction for higher energy density

Green Car Congress

This chemical sequence stores and releases energy on demand. The chemical reaction for lithium superoxide or peroxide only involves one or two electrons stored per oxygen molecule, whereas that for lithium oxide involves four electrons. —co-author Rachid Amine More electrons stored means higher energy density.

U of Sydney researchers find evidence of how hydrogen causes steel embrittlement

Green Car Congress

Lead researcher Dr Yi-Sheng Chen from the Australian Centre for Microscopy and Microanalysis and Faculty of Engineering at the University of Sydney said these findings were an important step to finding a safe solution to produce, store and transport hydrogen. Hydrogen is a low carbon fuel source that could potentially replace fossil fuels.
