Diesel challenge: The hybrid technology Hyundai uses in its Ioniq is advanced and cheap enough that it could replace diesel variants. Woong-chui Yang, vice chairman of R&D at Hyundai, explains that the total switch is still some four to five years away, as the carmaker would need to incorporate space for the battery.
Advanced hybrid: Chrysler’s Pacifica Hybrid is a most efficient plug-in hybrid that can run all-electrically at speeds of up to 120 mph on its 16 kWh battery that lasts for about 30 miles. Basically, the Pacifica Hybrid performs like an electric car with a motor that is used to start the engine and act as a generator.
Stationery back-up: Researchers from EPFL and EMPA have come up with an intermediate storage system for fast-charging stations. A lithium battery the size of a shipping container slowly but constantly charges at low level from the grid. During peak times, the buffer battery tops up the EV battery quickly. A demonstrator is working.
Five times more energy density is the promise of a new Li-air battery by Argonne. The lithium-oxygen battery is based on lithium superoxide. The latter allows in theory for a closed system that does not require the intake of oxygen from outside sources. The next step is the development of better catalysts.
