Fuji Pigment’s ionic liquids could be the key to a practical aluminum-air battery
Fuji Pigment is synthesizing ionic liquids for use as electrolytes in Li-ion batteries, as well as for the company’s own aluminum-air battery, which is currently under development. Ionic liquids are compounds composed of organic cations such as imidazolium ions and pyridinium ions, and anions such as bromide, fluoride, and chloride. Fuji Pigment has synthesized imidazolium-,… Read more »
A123 and Argonne collaborate to develop a safer cathode
A123 Systems has announced an agreement with Argonne National Laboratory to collaborate on a three-year, multi-million-dollar cathode development program that will focus on improving cathode safety without compromising energy density or battery life. A123 will leverage its battery expertise to commercialize advances in nickel manganese cobalt oxide (NMC) technology originally developed by Argonne, which already… Read more »
Proterra Catalyst electric bus logs 600 miles on a single charge
Electric bus maker Proterra has unveiled the newest addition to its fleet: the Catalyst E2 series, which features energy storage capacity of 440-660 kWh. Last month an E2 series vehicle logged more than 600 miles on a single charge under test conditions. The Catalyst E2 series’ nominal range of 194-350 miles makes it capable of… Read more »
Researchers use wide-bandgap material to make inverter smaller and lighter
Researchers at North Carolina State University have developed a new type of inverter that offers superior efficiency in a smaller and lighter package than current models. Conventional inverters rely on components made of silicon. The NC State team has developed an inverter using off-the-shelf components made of the wide-bandgap semiconductor material silicon carbide (SiC). “Our… Read more »
XALT claims unprecedented cycle life performance for its new lithium titanate batteries
XALT Energy, a manufacturer of prismatic, large-format battery cells and packs, has launched a new Lithium Titanium Oxide (LTO) cell that it says has achieved better cycle life performance over a wider range of operating conditions than any lithium-ion cell ever built. XALT’s Li-ion LTO cell offers specific energy greater than 76 wh/kg, and specific… Read more »
Daimler/BYD introduce new DENZA 400-kilometer EV for China
Daimler and BYD have been building new energy vehicles for the Chinese market under the DENZA brand since 2014. Now their joint venture, BYD Shenzhen Daimler New Technology (BDNT), has introduced a new EV with a range of up to 400 km (249 miles). The DENZA 400 features an upgraded battery – capacity has been… Read more »
New separator membrane could enable faster charging, eliminate thermal runaway
Researchers from Ohio State University have designed a thin plastic membrane that could improve the charging speed of current batteries, and possibly enable a new type of battery as well. In a study published in the journal Energy & Environmental Science, assistant professor Vishnu-Baba Sundaresan and doctoral student Travis Hery argue that current battery designs… Read more »
Wireless charging and autonomous vehicles will mobilize the smart city
By Alex Gruzen, CEO of WiTricity There’s no question that autonomous electric vehicles are coming. From Google and Uber to Tesla, BMW and Nissan, the world’s most innovative brands are conceiving and bringing to market entirely new modes of transportation that will revolutionize the ways in which we travel. According to Navigant Research, by 2035… Read more »
Bender launches a new off-the-shelf automotive-grade isolation monitoring device for EVs
Traditional 12-volt automotive batteries are grounded to the metal chassis of vehicles for a few different reasons, mainly driven by cost. Using the metal frame as a common ground essentially reduces the number of wires needed for all of the 12-volt systems by half – saving money and reducing weight. For example, to power a… Read more »
