Juggling charging: Two patents filed by Tesla, point to preparations for times when super chargers will have to handle many cars at once. U.S. Patent Application 2013/0057209 and 2013/0307475 outline prioritisation models according to state-of-charge, battery temperature or time of arrival.
Hybrid boat: At the Düsseldorf boat show, Italian Azure Embark presented the Ethos 30 or E30. The hybrid boat is equipped with a 13 kW electric motor powered by a 9.2 kWh LiFePO4 battery allowing for a 20 hour cruise at 3.5 knots. Solar panels on the roof are “primarily accessories,” says the company but when in hybrid mode, the E30 will travel 7,000 nautical miles (8,055 mi).

Lubricant turned electrolyte: Researchers at the University of North Carolina and UC Berkeley, have found a new class of nonflammable electrolytes for li-ion batteries. These electrolytes are based on functionalised perfluoropolyethers (PFPEs), usually used as a heavy-duty lubricant, and remain stable at temperatures beyond 200 °C.
Electrically grown anode: Researchers at Limerick University and University College Cork (Ireland) have developed anodes for li-ion batteries from tin-seeded germanium nanowire arrays. The anodes “grow” into a mechanically stable yet porous structure after about 100 charging cycles, providing a stable anode for about 1,100 cycles.
