Modern technology allows you to return to more than 92% of critical precious metals from lithium-ion batteries and create restored products productive at the level of new ones.
The group of scientists from the Polytechnic Institute of Wuster (USA) developed a procedure for processing lithium-ion batteries, which simultaneously and safely for the environment, reports Techxplore.
The new hydrometallurgical technology is focused on processing worn cathodes with low nickel content – materials that are usually difficult to restore to standard methods. Unlike traditional processing, the new technique gives you to restore more than 92% of precious metals – nickel, cobalt and manganese – and make a high -performance cathode powder.
Tests showed that batteries made using processed materials show effectiveness similar to the main batteries of the raw materials: they maintain 88% of the capacity after 500 charge cycles and more than 85% after 900 cycles in commercial batteries.
In addition, the new method consumes 8.6% less energy than ordinary hydrometallurgy, and reduces CO2 leaks by 13.9%, making it more attractive -from a point of view to the environment.
We remind you, earlier that it was reported that in China they created a nuclear battery that could work for 50 years.
