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.

BMW Manufacturing Introducing Hydrogen Fuel Cell Material Handling Equipment

Green Car Congress

Fuel cells offer a much longer operating life than lead-acid batteries. On average, it takes about 20 minutes to re-fuel a depleted battery. million kilowatt hours per year of electricity consumption at the plant that would have been used to charge a battery-powered fleet.

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.

A question about bidirectional charging was also asked. Elon Musk noted that bidirectional charging is not that useful since Powerwall is better. The service’s rollout in Texas will include $30 charging at night for customers who sign up for Tesla Electric. He estimates 10 models or so should be enough.

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. and re-evaluate their expectations for range. The reverse happens on discharge. Click to enlarge.

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.
