Japanese start-up seeks to commercialize dual-carbon battery technology; anion intercalation

Green Car Congress

Start-up Power Japan Plus announced plans to commercialize a dual-carbon battery technology, which it calls the Ryden dual carbon battery. Dual-carbon (also called dual-graphite) batteries were first introduced by McCullough and his colleagues at Dow Chemical in a 1989 patent, and were subsequently studied by Carlin et al.

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, carbon-based hosts cannot trap LiPS.

China team reports high-rate, high-capacity, long lifecycle Li-sulfur cell using nitrogen-doped graphene cathode material

Green Car Congress

The cells also exhibited an ultralong cycle life exceeding 2000 cycles and an extremely low capacity-decay rate (0.028% per cycle)—among the best performance demonstrated so far for Li/S cells, according to the researchers. The achieved best performance for earlier nitrogen-doped graphene-S nanocomposites was about 671 mA h g ?

Alkaline surfactant polymer flooding shown to improve recovery in very mature oilfield by more than 300%

Green Car Congress

In a report on Enhanced Oil Recovery (EOR) production research published in 2000, the DOE described ASP: The alkaline-surfactant-polymer (ASP) process evolved from the early studies on micellarpolymer flooding. The principal advantage of this process is its low cost. water production.

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

The possibility of a flow-through mode for the cathode allows flexibility of the cell design for safe, large-capacity electrical-energy storage at an acceptable cost, they conclude. His technology was used in the first commercial Li-ion battery, launched by SONY in 1991. In 2009, US Energy Secretary Steven Chu named Dr. John B.
