Three more Gigafactories? Tesla says it will make decision this year, where to build Gigafactories 3,4, and 5. The first two battery mega facilities are in Nevada and Buffalo (New York). The latter is mainly for SolarCity but now dubbed Gigafactory 2. For the rest, let the bidding begin.
EQ Power+ is Mercedes’ new label for any performance plug-in hybrid by AMG. The strongest of the pack is surely the Formula 1 racer, that has just been presented. This season’s F1 W08 EQ Power+ has a new styling and stronger hybrid drive.
Battery based on sugar: Researchers at Vanderbilt University in Tennessee, have developed a room-temperature sodium sulphur battery based on a microporous template made from sugar. Over 98% Coulombic efficiency and durabilty make it competitive with Li-ion batteries.
Renesas-Intersil merger approved: American chip maker Intersil has been acquired by its Japanese competitor Renesas. The deal was initiated last autumn and has now been approved by the CFIUS in the States. Both manufacturers have components for electric and hybrid vehicles in their portfolio.
Huawai, fool's gold battery, Vanderbilt University, Plug Power + 3M.
Faster charger: Huawei presented a new Li-ion battery at the Battery Symposium in Japan, said to charge ten times faster than current variants, reaching 68% capacity in two minutes. According to Huawei, this is made possible by bonding heteroatoms to graphite anodes, saying the technology could revolutionize the EV market.
Fool’s gold battery: Researchers from Empa and ETH Zurich have developed a battery made from iron, sulfur, sodium and magnesium, a combination also referred to as “fool’s gold.” The elements are more abundant and cheaper than lithium and especially fit for stationary batteries. So far, however, they are not powerful enough for electric cars.
Ultrasmall nanoparticles: Unlike using bulk iron pyrite, researchers at Vanderbilt University found that using iron pyrite dots in sodium and lithium works, because the iron can move close to the surface. Moreover, the sodium and lithium reacts with the sulphur in the iron pyrite, changing its form to store energy.
Plug Power and 3M sign supply agreement: The latter will deliver membrane electrode assemblies (MEAs) for Plug Power’s proton exchange membrane (PEM) fuel cell stacks. These will be built in the facilities in Latham, NY and Spokane, WA, and will be ready for delivery before the end of the year.
