The Honda Research Institute has collaborated with scientists from the California Institute of Technology (CalTech) and NASA's Jet Propulsion Laboratory on a new battery chemistry that could provide a more energy-efficient and environmentally friendly alternative to lithium-ion batteries, one on Friday in Science Magazine published paper.
Currently, the world's electric cars ̵
1; with few exceptions – are powered by lithium-ion batteries. Lithium ions have many advantages over older battery chemicals, such as nickel metal hydride, because of the more favorable charge and discharge rates and the fact that it is less likely to develop a "memory" if it is not permanently completely discharged before it recovers is charged. 19659005] Lithium-ion batteries also have some significant drawbacks, namely the environmental damage that occurs when lithium and cobalt are broken down, and the tendency of the cells to catch fire and very difficult to delete if they do. The fluoride-based battery chemistry developed by Honda, NASA and CalTech would mitigate many of these problems.
One of the most exciting benefits of fluoride chemistry is its potential to be much more energetic than lithium. This would mean that an electric car equipped with this new battery technology could continue with a physically much smaller battery pack from a pack of the same physical size or distance.
The fluoride ion battery technology is not completely new. However, previous versions required that the solid electrolyte be heated up to 300 degrees Fahrenheit to function properly. The progress of Honda, JPL and CalTech is to provide a liquid-liquid liquid electrolyte (also referred to as tetraalkylammonium salt-fluorate ether combination) at room temperature and a copper-lanthanum trifluoride core-shell cathode (also a new development) which together form a new solution form functional cell. Teamwork, as they say, makes the dream a success.
That's all pretty cool and very exciting, but do not expect the next Honda Insight to shake fluoride ion batteries. The technology is promising but probably still far from ready for mass production.
