Important discoveries always changed the world. Researchers at the University of Uppsala in Sweden have developed a more sustainable electric vehicle (EV) battery that can be charged in a matter of seconds.
They are built using quinones as the active material, so organic carbon compounds that are plentiful in nature and occur during photosynthesis. This battery does not require the use of precious metals. Instead, an acidic aqueous solution is used as an electrolyte to transport ions inside the battery. The liquid makes the battery safe as it removes the hazard of explosion or fire. The new battery can be charged and discharged over 500 times without any significant loss to capacity. Organic proton battery also retains properties such as capacity down to as low as -24 °C (-11 °F). ”The experimental proton battery is much more environmentally friendly.
For the new battery design, the electrodes are made out of solid polymers of certain quinones, immersed in watery solution that acts as the electolyte. For the instant, it’s only a small button cell battery,with atiny capacity of 60 mAh. “A great deal of further development still remains to be done on the battery before it becomes a household item; however, the proton battery we have developed is a large stride towards being able to manufacture sustainable organic batteries in future,” says Christian Strietzel, first author of the study.
