The University of Leicester says its scientists have developed a new technique for recycling lithium-ion batteries using vegetable oil.<\/h4>\n

The patent-pending technology extracts battery-grade metal oxides from crushed batteries using water and vegetable oil.<\/p>\n

The University said the technique purifies lithium-ion battery black mass, a low-value mixture of anode, cathode, and other materials, directly within minutes at room temperature.<\/p>\n

The research was led by Professor Andy Abbott and Dr Jake Yang at the University of Leicester, working under the Faraday Institution\u2019s ReLiB project.<\/p>\n

Dr Jake Yang from the University of Leicester School of Chemistry commented: \u201cThis quick, simple and inexpensive method could revolutionise how batteries are recycled at scale.<\/p>\n

\u201cWe now hope to work with a variety of stakeholders to scale up this technology and create a circular economy for lithium-ion batteries.\u201d<\/p>\n

This quick, simple and inexpensive method could revolutionise how batteries are recycled at scale.<\/p>\n<\/blockquote>\n

Current recycling techniques use a combination of furnace heat treatment to burn off graphite, which produces carbon emissions across the electric vehicle value chain.<\/p>\n

Most people know oil and water do not mix unless you add soap, however, the research has shown that ultrasound can create nano-droplets of oil that are stable for weeks.<\/p>\n

The new process developed by the University of Leicester uses these oil nano-droplets to purify battery waste, commonly known as \u201cblack mass\u201d, as it contains a mixture of carbon (graphite) and valuable lithium, nickel and cobalt metal oxides (NMC).<\/p>\n

The oil nano-droplets stick to the surface of the carbon and act as a \u201cglue\u201d to bind hydrophobic graphite particles together to form large oil-graphite conglomerates.<\/p>\n

These particles float on water, leaving the valuable, hydrophilic lithium metal oxides untouched. The University said the oil-graphite conglomerate can then be skimmed off to leave pure metal oxides.<\/p>\n
