Lithium-battery carbon dioxide, which are effective lithium-ion seven times, the first time withstood 500 charge-discharge cycles

Currently no serious competitors lithium-ion batteries there is little, but scientists do not cease to search for new eco-friendly and at the same time more effective solutions. One promising area was the development of the possibility of using natural carbon dioxide. And that's what scientists have succeeded.

A research team from the University of Chicago, Illinois was able to create a prototype of carbon-dioxide lithium battery, which has successfully withstood the 500 charge-discharge cycles. Command failed to convert carbon dioxide into a solid carbonaceous material.

Initially, the biggest challenge has been recharging a battery. After all, despite the fact the use of a new type of electrochemical reaction, which allowed raise the discharge voltage is almost doubled, so the battery is stored only 10 cycles charging.

The reason for such a rapid failure of the effect was rapid accumulation of carbon on the catalyst during charging.

As a result of this accumulation is not only blocking of the active sites of the catalyst and preventing diffusion of carbon dioxide, but also led to decomposition of the electrolyte, when it was active (charged) condition.

The scientific team through numerous experiments established that the elimination of these adverse events need to implement nanoflaki molybdenum disulfide in the cathode catalyst and the electrolyte to replace the old hybrid consisting of the ionic liquid and dimethyl sulfoxide.

This combination would significantly reduce the accumulation of carbon on the cathode and thus improve the survivability of the battery 50 to charge-discharge cycles.

While this technology is far from commercial application, since the cost of the battery is quite high, but Scientists are optimistic and believe that the market will be able to present a worthy competitor lithium-ion in the coming years batteries.
