The usually held view that lithium-ion batteries are not being recycled isn't valid. It's simply that China has essentially cornered the market, specialists state.
China recycled around 67,000 tons of lithium-ion batteries a year ago, or 69 percent of all the stock available for recycling around the world, as indicated by Hans Eric Melin, founder of U.K.- based Circular Energy Storage.
Another 18,000 tons were recycled in South Korea, generally for the Chinese market, said Melin, the leading authority on battery recycling. These figures are approximate because recyclers often hoard batteries to take advantage of spikes in materials pricing, he said.
This year, as much as 100,000 tons of lithium-ion batteries could be recycled all around, with China planning to take an expanding share to develop materials supplies for its burgeoning battery business.

China has profited by around the time of cell phone manufacturing, which has allowed it to perfect lithium-ion battery recycling as a major part of a developing handset renovating industry. Three out of four telephones that are sent for revamping go to China, Melin said.
“When we talk about low recycling rates of phones, of tablets, that’s not true, because we are exporting them for refurbishment and for remanufacturing,” said Melin. “But that is going on in China. They have had for a long time a large feedstock of batteries from consumer electronics.”
Indeed, even today, around 80 percent of lithium-ion batteries reaching the end of life from portable electronic devices, he added.
'Longtail' of recycling hopefuls
This feedstock has helped the emergence of Chinese lithium-ion recycling behemoths, for example, GEM, which began as a piece collector and is currently a huge cathode manufacturer.
A year ago, the organization's appetite for cathode materials outstripped its recycling capacity and led it to sign a deal agreeing to get 35 percent of the yearly cobalt production from mining giant Glencore. The arrangement later fell apart after cobalt costs dropped 25 percent.
Somewhere else in China, recent scrap organization Hunan Brunp Recycling Technology, a subsidiary of lithium-ion battery leader CATL since 2015, a year ago recycled around 30,000 tons of batteries.
Meanwhile, Quzhou Huayou Cobalt New Material has about 60,000 tons of lithium-ion battery recycling capacity a year and recycled around 10,000 tons in 2018, Melin said.
Nearby these and two other main players, Ganzhou Highpower Technology and Guangdong Guanghua Sci-Tech, Melin said there was a "long tail" of hopefuls competing to develop in the market.
In North America and Europe, recycling is viewed as a waste disposal action that companies ought to be paid to do. In any case, competition is so intense in China that recyclers there are eager to pay to get their hands on dead batteries.
This appetite implies China's grip on lithium-ion recycling appears to probably grow. American and European recycling companies have great procedures but also may struggle to discover the volumes of utilized batteries required for profitable operations, Melin said.
Tailwind from EVs
Chinese recyclers may finish slowing production this year after the government declared plans for a 50 percent cut on an electric vehicle buy subsidies. Be that as it may, any scaling is probably going to be a blip rather than a trend.
“Lithium-ion battery recycling surged last year in China, particularly from portable electronics, due to high cobalt prices,” noted Milan Thakore, a research analyst at Wood Mackenzie. “The country is also scaling up EV battery recycling rapidly.”
China sold more electric vehicles than the remainder of the world consolidated a year ago, said Thakore. "Therefore, it will need to lead the way in recycling, too,” he said. “On top of this, many of the vehicle electric batteries are lower quality and have already reached the end of their life."
Melin said that electric vehicle battery recycling was ready to make up a developing portion of the feedstock for Chinese companies, however "it will take much longer time than individuals anticipate."
By 2025, Circular Energy Storage appraises that batteries from electric autos and transports will at present represent around 40 percent of all-out recycling volumes. Compact gadgets will represent another 40 percent, with the balance originating from other recycling categories.
