Battery is created with a specific capacity seven times more than lithium-ion batteries

Employees of the Chicago campus of the University of Illinois have created the first working prototype lithium-dioxide of carbon of the battery. This battery has a storage density of energy, seven times more than lithium-ion.

The study is published in the journal Advanced Materials. The document States that scientists have been able to get rid of the main drawback of lithium-carbon-dioxide battery (Li–CO2): a small number of recharge cycles (about 100) caused by the release of carbon during chemical reactions. I had to change the composition of the electrolyte: for dimethyl sulfoxide, which is a good conductor of ions, added nancekuke molybdenum disulfide.

The hybrid electrolyte is allowed to run reversible electrochemical cycle, which completely neutralizes CO2 and achieve 500 charge cycles. The density of the energy storage of the battery is 1876 watt-hours per kilogram of mass that is seven times more than it can offer today’s lithium-ion batteries. An even greater potential – in lithium-sulfur power sources: their theoretical specific capacity is 2600 watt-hours per kilogram.

In December last year, the staff of Honda Research Institute, together with scientists from Caltech and the jet propulsion Laboratory of NASA developed a new type of electrolyte which will allow you to create batteries with high storage density charge and low operating temperature. Thanks to him, scientists have made solid-state fluoride-ion battery that operates at room temperature.

Can the development staff of the University of Illinois is considered a breakthrough?
