ROME – A battery with a negligible environmental impact and that can recharge in a few seconds. A dream that many scientists try to turn into reality, even if the road appears long and winding. These include researchers from the University of Uppsala, Sweden, who have developed a fully organic proton battery in the laboratory that can be recharged in a few moments. Not only that: it can be loaded and unloaded over 500 times without any significant loss of capacity.
The researchers – Their work has been published in the scientific journal Angewandte Chemie – they have been able to demonstrate that their battery can be easily recharged using a solar cell. Charging can also be performed without the aid of advanced electronics which, for example, require lithium batteries. Another advantage is that it is not affected by the ambient temperature. “I am sure many people are aware that the performance of standard batteries decreases at low temperatures. We have shown that this battery maintains properties such as capacity down to -24 degrees centigrade,” he explained. Christian Strietzel of the Department of Science and Materials Engineering of the University of Uppsala.
Many of the batteries produced today have a great environmental impact, not least because of the extraction of the metals used for production. For this reason, the research team chose quinones as the active material in the battery. These organic carbon compounds are abundant in nature. An acidic aqueous solution was used as the electrolyte, the vital component that carries the ions inside the battery. In addition to being environmentally friendly, the complex of these elements also provides a safe battery that is free from explosion or fire hazards.
