Monash University team develops graphene-based supercapacitor with energy density of 60 Wh/L

Green Car Congress

A research team at Monash University (Australia) led by Professor Dan Li of the Department of Materials Engineering has developed a new strategy to engineer graphene-based supercapacitors (SC), resulting in an energy density of 60 Wh/liter—comparable to lead-acid batteries and around 12 times higher than commercially available SCs.

False Starts: The Story of Vehicle-to-Grid Power

Cars That Think

Photo-illustration: Max-o-matic; photo source: M&N/Alamy Some operators of early direct-current power plants at the turn of the 20th century solved the problem of uneven power output from their generators by employing large banks of rechargeable lead-acid batteries, which served as a kind of buffer to balance the flow of electrons.

In Li-ion batteries, Li ions (Li + ) leave the cathode during charging and move through the electrolyte and separator to intercalate into the anode. As the technology gets fixed, the anode is more of an issue related to fast charge. Generic Li-ion cell and various component technologies. The reverse happens on discharge.

MIT Battery Breakthrough Could Revolutionize Electric Cars : Gas 2.0

Tony Karrer Delicious EVdriven

The breakthrough could revolutionize electric car battery technology and pave the way for ultra-fast charging electric vehicles in as little as two years. When the team tested the newly-coated cathode, they discovered it could be charged and discharged in as little as 9 seconds. by RSS or sign up by email. Herron makes a valid point.
