Lithium battery recycling

Since the 1990s, the use of lithium battery has become more and more widespread.

Today, lithium-ion batteries are almost everywhere, from laptops, mobile phones to electric vehicles and energy storage devices. As a result, the number of discarded lithium-ion batteries has increased at an alarming rate. Some studies predict that by 2030, the global scrapped lithium-ion batteries will reach more than 11 million tons. At present, the recycling rate of waste lithium-ion batteries in the United States is less than 5%. If this problem cannot be effectively solved, it will have adverse effects on both the health of the people and the natural ecological environment.

li-ion-battery

Although the prospects are good, the current volume of scrapped lithium batteries is relatively “bleak”. Scrapped power batteries include not only ternary batteries, but also lithium iron phosphate batteries, lithium manganese oxide batteries, etc. Among them, the more popular ones are only the relatively high-value ternary batteries.

The service life of lithium batteries is generally about 8 years, and the lithium battery recycling market has not yet ushered in large-scale demand. At present, in the lithium battery recycling market, the main source of scrapped power batteries is still new energy vehicles before 2015, most of which are service vehicles such as buses and taxis, which is far from meeting the available production capacity.

At the same time, industry analysts pointed out that after the power batteries reach the service life, most of the “retired” lithium batteries have flowed into the stage of cascade utilization.

New process makes battery production more eco-friendly

Switching from gas-powered cars to electric vehicles is one way to reduce carbon emissions, but building the lithium-ion battery that power those EVs can be an energy-intensive and polluting process itself. Now researchers at Dalhousie University have developed a manufacturing process that is cheaper and greener.

“Making lithium-ion battery cathode material takes a lot of energy and water, and produces waste. It has the biggest impact on the environment, especially the CO2 footprint of the battery,” says Dr. Mark Obrovac, a professor in Dalhousie University’s Departments of Chemistry and Physics & Atmospheric Science.

li-ion-battery

“We wanted to see if there were more environmentally friendly and sustainable—and less expensive—ways to make these materials.”

Most electric vehicle batteries use lithium nickel manganese cobalt oxide (NMC), with the elements mixed in the crystal structure of the cathode. They are typically made by dissolving the elements in water then using the crystals that form when the elements come together as a solid.

That process takes a lot of water—which then has to be treated to clean it—and energy, which is the main source of the cost and carbon footprint of the batteries. Using the Canadian Light Source (CLS) at the University of Saskatchewan, Obrovac and his team investigated whether they could use an all-dry process to get the same results while saving energy, water, and money.

Their work has been published in two papers, in ACS Omega and the Journal of the Electrochemical Society.

“We wanted to see, can you get the same quality if you take dry materials and combine them using simple processes that you’d find in any large-scale factory and heat them up,” he says. “And under what conditions can you do that to get commercial-grade material while cutting out the water and the waste?”

Cathodes made from dry materials are sometimes not as homogeneous as those made in water, so the team tried a variety of methods using different oxides and heating regimes under different temperatures and pressures to determine what worked best.

They used the Brockhouse beamline at CLS to peer inside the furnace as they tried these different experiments, to see exactly what was happening during the process. “What we found was important information about how we can improve the process so that what comes out is a higher-grade NMC-type cathode material,” says Obrovac.

The highest quality cathodes available now are made from single crystals with particles about 5 microns in diameter. By carefully adjusting their starting materials and furnace conditions, Obrovac’s team was able to reproduce those qualities using an all-dry process, making cathode materials comparable to the best ones on the market today.

Obrovac has partnered with the Nova Scotia-based battery company NOVONIX, which is using all-dry processes to produce cathode materials at the company’s pilot-scale facility in Dartmouth. That facility is capable of producing 10 tonnes per annum of cathode material, with methods that offer an estimated 30% lower capital costs than the conventional (wet) methods, 50% lower operating costs, and uses 25% less energy, while requiring no process water, and generating zero waste.

“These are big numbers, it’s very much a step-change in the production of these battery materials,” says Obrovac. “It should result in lower-cost batteries overall with a substantially lower global warming footprint.”

New strategy improves performance of spent high-voltage lithium cobalt oxide batteries

In a study published in Advanced Materials, a research team led by Prof. Zhang Yunxia from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences has developed an integrated bulk and surface commodification strategy to upgrade spent lithium cobalt oxide (S-LCO) batteries to operate at high voltages.

As the demand for high energy density storage devices grows, there’s a need to find sustainable ways to upgrade old LiCoO2 (LCO) batteries into more stable, high-voltage cathode materials.

In this study, the researchers developed a simple and effective method for upgrading LCO batteries. They used a combination of wet chemical treatment, heating, and a special phosphorus coating technique.

This process involved adding extra lithium, applying a uniform coating of lithium phosphate/cobalt phosphide (LPO/CP) to the surface, and incorporating manganese into the bulk material, along with a gradient of phosphorus near the surface. These modifications were all achieved simultaneously, resulting in significantly improved battery performance.

The result of these modifications is an improved LCO cathode, named MP-LCO@LPO/CP, which shows significantly improved electrochemical performance. The improved cathode exhibits high specific capacity and excellent cycling stability.

The researchers also investigated why the upgraded cathode performs so well at high voltages. They found that the modifications improve both structural stability and electrochemical properties, resulting in improved battery performance.

“This method is simple and easy to scale up, so it could also be used to recycle other waste cathode materials. This approach has great potential for the sustainable development of the lithium-ion battery industry,” said Prof. Zhang.
