Argonne releases updates to GREET models; LiMn2O4 replaces cobalt for Li-ion batteries

Green Car Congress

Li-ion battery production pathways using LiMn 2 O 4 are added replacing Li-ion battery with Li 2 CoO 2. Alberta mix is defined and used for bitumen recovery and upgrading in oil sand operation. Recycling pathways for LiMn 2 O 4 are also included.

Can Flow Batteries Finally Beat Lithium?

Cars That Think

The cell of a flow battery uses two chemical solutions containing ions, one acting as the anolyte (adjacent to the anode), the other as the catholyte (near the cathode). Typical redox flow batteries use ions based on iron chromium or vanadium chemistries; the latter takes advantage of vanadium’s four distinct ionic states.

MIT Battery Breakthrough Could Revolutionize Electric Cars : Gas 2.0

Tony Karrer Delicious EVdriven

The discovery came when MIT researchers Byoungwoo Kang and Gerbrand Ceder found out how to get a common lithium compound to release and take up lithium ions in a matter of seconds. The breakthrough could revolutionize electric car battery technology and pave the way for ultra-fast charging electric vehicles in as little as two years.

The MiEV runs on a lithium-ion battery pack that can be charged in seven or so hours on a 240-volt line. The electric car features three different battery options, two different Lithium-based (LI) systems – A123Systems and Enerdel as well as a Sodium-Nickel battery Zebra (Mes-Dea). safety requirements.

GM killed that car because of back room deals with oil companies, and now they expect us to believe that they are just so cutting edge now? GM killed that car because of back room deals with oil companies" GM "killed" that experiment because it wasnt even CLOSE to being cost effective. It is 12 years later. Interesting in any case.
