We have just mentioned about Zinc-Air as the potential next generation battery technology replacing Lithium-Ion, now seems that there is another competing technology known as Ionic batteries that is claimed to be able to last even longer with up to 11 times of energy density as compared to typical Lithium battery.
The project was funded by US Department of Energy in the form of research grant to Scottsdale, a Fludic Energy based in Arizona and according to Cody Friesen, its founder, they have been spending many years in experimenting the ionic liquids and realized that it would able to scale up energy density significantly with less drying out issue which is suitable for various usages even in future electric vehicles in automotive industry. With its high electrochemical stability of up to five volts, it even allows energy dense metal, which is higher grade than zinc material to be used and eventually can formulate an extremely high capacity density of up to 1600 watt-hours per kilogram. In comparison, this is almost equivalent to 11 times of what existing Lithium-Ion battery can achieve in today’s mobile computing segment, and is definitely much more efficient, which is another three to four times longer than Zinc-Air technology. Besides, the technology is believed to be more cost effective which consumes only one-third of existing cost needed to build Lithium Ion cells in volume production.
However, since this is still purely in research and development stage, there is no projected date on when we can expect to see it being integrated into actual end products.
