How China is Cornering the Lithium-ion Cell Recycling Market

The generally held view that lithium-ion batteries usually are not being recycled will not be true. It’s simply that China has just about cornered the market, consultants say.

China recycled round 67,000 tons of lithium-ion batteries final yr, or 69 % of all of the inventory obtainable for recycling worldwide, based on Hans Eric Melin, founding father of U.Okay.-based Round Power Storage.

One other 18,000 tons was recycled in South Korea, principally for the Chinese language market, mentioned Melin, a number one authority on battery recycling. These figures are approximate as a result of recyclers typically hoard batteries to make the most of spikes in supplies pricing, he mentioned.

This yr, as much as 100,000 tons of lithium-ion batteries might be recycled globally, with China aiming to take an rising share to construct up supplies provides for its burgeoning battery enterprise.

China has benefited from round a decade of cell phone manufacturing, which has enabled it to good lithium-ion battery recycling as a part of a rising handset refurbishing trade. Three out of 4 telephones which are despatched for refurbishing go to China, Melin mentioned.

“After we speak about low recycling charges of telephones, of tablets, that’s not likely true, as a result of we’re exporting them for refurbishment and for remanufacturing,” mentioned Melin. “However that is happening in China. They’ve had for a very long time a big feedstock of batteries from client electronics.”

Even immediately, about 80 % of lithium-ion batteries reaching finish of life are from transportable digital gadgets, he mentioned.

‘Lengthy tail’ of recycling hopefuls

This feedstock has helped help the emergence of Chinese language lithium-ion recycling behemoths resembling GEM, which began out as a scrap collector and is now a serious cathode producer.

Final yr, the corporate’s urge for food for cathode supplies outstripped its recycling capability and led it to signal a deal agreeing to purchase 35 % of the annual cobalt manufacturing from mining large Glencore. The deal later fell aside after cobalt costs dropped 25 %.

Elsewhere in China, erstwhile scrap firm Hunan Brunp Recycling Know-how, a subsidiary of lithium-ion battery chief CATL since 2015, final yr recycled about 30,000 tons of batteries.

In the meantime, Quzhou Huayou Cobalt New Materials has roughly 60,000 tons of lithium-ion battery recycling capability a yr and recycled round 10,000 tons in 2018, Melin mentioned.

Alongside these and two different main gamers, Ganzhou Highpower Know-how and Guangdong Guanghua Sci-Tech, Melin mentioned there was a “lengthy tail” of hopefuls vying to develop available in the market.

In North America and Europe, recycling is seen as a waste disposal exercise that corporations ought to be paid to hold out. However competitors is so intense in China that recyclers there are keen to pay to get their palms on useless batteries.

This urge for food means China’s grip on lithium-ion recycling appears prone to develop. American and European recycling corporations have good processes however would possibly battle to seek out the volumes of used batteries wanted for worthwhile operations, Melin mentioned.

Tailwind from EVs

Chinese language recyclers could find yourself slowing manufacturing this yr after the federal government introduced plans for a 50 % minimize on electrical car buy subsidies. However any scaling again is prone to be a blip relatively than a pattern.

“Lithium-ion battery recycling surged final yr in China, notably from transportable electronics, attributable to excessive cobalt costs,” famous Milan Thakore, a analysis analyst at Wooden Mackenzie. “The nation can be scaling up EV battery recycling quickly.”

China bought extra electrical automobiles than the remainder of the world mixed final yr, mentioned Thakore. “Due to this fact, it might want to cleared the path in recycling, too,” he mentioned. “On high of this, most of the car electrical batteries are decrease high quality and have already reached the top of their life.”

Melin mentioned that electrical car battery recycling was poised to make up a rising portion of the feedstock for Chinese language corporations, however “it should take a for much longer time than folks anticipate.”

By 2025, Round Power Storage estimates that batteries from electrical automobiles and buses will nonetheless solely account for round 40 % of complete recycling volumes. Moveable electronics will account for an additional 40 %, with the stability coming from different recycling classes.
