Silica-based cathode enables long-life Li-S batteries

Green Car Congress

Scientists from the Daegu Gyeongbuk Institute of Science and Technology, Korea, have developed a novel silica-based cathode for lithium–sulfur batteries, thereby enabling the realization of batteries that can last for more than 2,000 charge/discharge cycles. However, using sulfur in batteries is tricky for two reasons.

Univ. of Texas researchers propose lithium- or sodium-water batteries as next generation of high-capacity battery technology; applicable for EVs and grid storage

Green Car Congress

Example of a lithium-water rechargeable battery. Researchers at the University of Texas, including Dr. John Goodenough, are proposing a strategy for high-capacity next-generation alkali (lithium or sodium)-ion batteries using water-soluble redox couples as the cathode. The present sodium-sulfur battery operates above 300 °C.

Why Warren Buffett is investing in electric car company BYD - Apr. 13, 2009

Tony Karrer Delicious EVdriven

Why hes banking on an obscure Chinese electric car company and a CEO who - no joke - drinks his own battery fluid. BYD CEO Wang Chuan-Fu figured out how to make cheaper batteries than the Japanese by replacing machines with migrant workers. By about 2000, BYD had become one of the worlds largest manufacturers of cellphone batteries.
