High stability: The EU-funded STABLE project successfully doubled durability of lithium air batteries. The researchers developed cells lasting for 100-150 rather than 50 charge cycles. Despite their high energy density, lifetime of the new Li-air batteries is still a far cry from those of Li-ion batteries.
Ready to tour the globe: Students of TU Eindhoven have finished their electric touring motorbike. First presented earlier this year, the Storm Pulse peaks at 75 kW. Included in the 340-kilo machine is the battery with 28,5 kWh said to last for 380 km. Next up is the race around the world in 80 days.
Potassium power: Researchers at the Oregon State University have a patent pending for a potassium-ion battery (KIB). Inserted into graphite, they managed to reach a capacity of 273 mAh/g in the KIB, while soft carbon as anode stabilised the potassium batteries further.
Double collaboration: Argonne National Laboratory opened two new collaborative centres. The Argonne Collaborative Center for Energy Storage Science (ACCESS) and Nano Design Works (NDW) shall both provide access to Argonne’s extensive scientific resources including R&D.

Lithium-air research: Scientists at the universities Graz, St. Andrews, Oxford and Amiens, as well as Collège de France have been able to better clarify the discharge process of lithium-air batteries. They say the key to increase capacity is an electrolyte with high donor number like i.e. sulfoxides or imidazole.

Next-gen lithium-sulfur cells: Battery specialist Oxis Energy says it developed such a cell with an energy density of 300 Wh/kg, increasing its capacity twelve fold to 25 Ah within 18 months. The company believes it can develop cells with an energy density of 500 Wh/kg by 2018. According to Oxis, vehicle manufacturers are already reviewing and evaluating the cell technology.
Supercapacitors for EVs: Researchers at the Queensland University of Technology have developed a lightweight supercapacitor, that was made into a thin film with a high power density. The supercaps could be embedded in a car’s body panels, roof, doors, bonnet and floor. The scientists say that once they increase energy density, the supercapacitors could allow for a range of around 500 kilometres.
Battery talks: Autoline Network airs a discussion between (among others) the CEO of LG Chem’s North American unit and the founder of Sakti3 about the future of batteries. The experts agree that for at least the next 10 to 15 years, nothing will be able to replace lithium cells.

Lithium-air research: Within the project ABILE (Air Batteries with Ionic Liquid Electrolytes), researchers from the BMW Group and the Universities of Rome, Münster and Seoul have optimized an ionic liquid electrolyte for Li-air batteries. The energy efficiency could be increased to 82 percent in a coin cell, compared with 60 to 70 percent for most existing Li-air batteries.
New battery research centre: The German state of Baden-Württemberg has invested 12 million euros in a research facility at the Helmholz Institute in Ulm. The new laboratories will enable the institute and its partners, the University of Ulm, Karlsruhe Institute of Technology, Centre for Solar Energy and Hydrogen Research and the German Aerospace Centre to work together even more closely.

Johnson Matthey buys Clariant’s LFP business: The largest producer of hydrothermal Lithium Iron Phosphate (LFP) worldwide has agreed to sell its Energy Storage business. For 75 million dollars, Johnson Matthey will take over the manufacturing plant in Canada, as well as the R&D and pilot plan in Germany. JM had already bought A123 System’s cathode factory in China in September.
Unsinkable e-boat: The Quadrofoil resembles a jet ski and supposedly makes you “fly above water.” Starting next year, it will be available starting at 15,000 euros for a version with a 3.7 kW motor, 4.5 kWh battery and 50 km range. There is also a limited edition with 100 km range priced at 22,500 euros.
