Engineers at Rice University have developed a cleaner, innovative process to turn end-of-life lithium-ion battery waste into new lithium feedstock.

The findings, recently published in the journal Joule, demonstrate how the team’s new “recharge-to-recycle” reactor recharges the battery’s waste cathode materials to coax out lithium ions into water. The team was then able to form high-purity lithium hydroxide, which was clean enough to feed directly back into battery manufacturing.

The study has major implications for the electric vehicle sector, which significantly contributes to the waste stream from end-of-life battery packs. Additionally, lithium tends to be expensive to mine and refine, and current recycling methods are energy- and chemical-intensive.

“Directly producing high-purity lithium hydroxide shortens the path back into new batteries,” Haotian Wang, associate professor of chemical and biomolecular engineering, co-corresponding author of the study and co-founder of Solidec, said in a news release. “That means fewer processing steps, lower waste and a more resilient supply chain.”

Sibani Lisa Biswal, chair of Rice’s Department of Chemical and Biomolecular Engineering and the William M. McCardell Professor in Chemical Engineering, also served as co-corresponding author on the study.

“We asked a basic question: If charging a battery pulls lithium out of a cathode, why not use that same reaction to recycle?” Biswal added in the release. “By pairing that chemistry with a compact electrochemical reactor, we can separate lithium cleanly and produce the exact salt manufacturers want.”

The new process also showed scalability, according to Rice. The engineers scaled the device to 20 square centimeters, then ran a 1,000-hour stability test and processed 57 grams of industrial black mass supplied by industry partner Houston-based TotalEnergies. The results produced lithium hydroxide that was more than 99 percent pure. It also maintained an average lithium recovery rate of nearly 90 percent over the 1,000-hour test, showing its durability. The process also worked across multiple battery chemistries, including lithium iron phosphate, lithium manganese oxide and nickel-manganese-cobalt variants.

Looking ahead, the team plans to scale the process and consider ways it can sustain high efficiency for greater lithium hydroxide concentrations.

“We’ve made lithium extraction cleaner and simpler,” Biswal added in the release. “Now we see the next bottleneck clearly. Tackle concentration, and you unlock even better sustainability.

Houston battery recycling co. expands globally with new India facility, Africa partnership

going global

Ace Green Recycling Inc., a Houston-operated sustainable battery recycling and technology solutions provider, announced it has finalized a lease agreement for a location to build one of India's largest battery recycling facilities in Mundra, Gujarat.

The facility will expand Ace's existing Indian commercial operations, which have been recycling lithium-ion batteries since 2023, including lithium iron phosphate ("LFP") chemistries.

The deployment of Ace’s LithiumFirst LFP battery recycling technology in India will coincide with the deployment of the company's technology in Texas. Last year, the company announced it planned to develop a flagship battery recycling plant in Texas for lead and lithium-ion batteries.

Ace also plans to establish 10,000 metric tons of LFP battery recycling capacity per year in India by 2026. The Mundra LFP battery recycling facility is expected to create up to 50 jobs.

The new facility plans to use Ace's LithiumFirst technology to recycle LFP batteries at room temperature in a fully electrified hydrometallurgical process that produces no direct (or Scope 1) carbon emissions and with zero liquid and solid waste.

"Ace's innovative technology enables profitable recycling of LFP batteries, even with the current low lithium price, by recovering significant amounts of these critical minerals,” Vipin Tyagi, Chief Technology Officer of Ace, said in a news release. “We believe that our successful operational demonstration positions us for future partnerships and collaborations that will unlock the full potential of our LithiumFirst technology in this market.”

Ace will also utilize its GreenLead recovery technology to recycle lead batteries at the new recycling park. The technology is considered a more environmentally friendly alternative to conventional smelting operations.

The company also reported visiting China for possible future expansion. According to a release, it launched a facility in Taiwan last year and is developing projects in Europe and Israel, as well.

Today, the company also announced that it was tapped by Spiro, one of Africa’s largest EV battery producers, as its global preferred recycling partner. According to a release, Ace will recycle end-of-life lithium-ion batteries, including LFP batteries, and waste from Spiro's battery manufacturing facilities.

Ace Green Recycling Inc. is headquartered in Houston and Singapore.

Japanese company launches solar module manufacturing at Houston-area plant

solar plant

A local subsidiary of a Japanese solar equipment manufacturer recently began producing solar modules at a new plant in Humble.

TOYO Co. Ltd.’s TOYO Solar LLC subsidiary can produce 1 gigawatt worth of solar modules per year at a 567,140-square-foot plant it leases in Lovett Industrial’s Nexus North Logistics Park on Greens Road. TOYO Solar’s next phase will accommodate 2.5 gigawatts’ worth of solar module manufacturing. The subsidiary eventually plans to expand manufacturing capacity to 6.5 gigawatts.

For now, TOYO Solar operates only one assembly line at the Humble plant. Once TOYO Solar has five assembly lines up and running, it could employ as many as 750 manufacturing workers there, according to Connect CRE.

TOYO says the plant enlarges its U.S. footprint “to be closer to the majority of its clients, meet the demand for American-made solar panels, and contribute to the growing demand for secure, sustainable energy solutions as demands on the grid continue to rise.”

Last month, TOYO purchased the remaining 24.99 percent stake in TOYO Solar to make it a wholly owned subsidiary. TOYO entered the Houston-area market through its 2024 acquisition of a majority stake in Solar Plus Technology Texas LLC.

Record $9.6M fine for Houston-based co. after Gulf of Mexico oil spill

In the news

Pipeline safety regulators on Monday, January 5, assessed their largest fine ever against the company responsible for leaking 1.1 million gallons of oil into the Gulf off the coast of Louisiana in 2023. But the $9.6 million fine isn’t likely to be a major burden for Third Coast to pay.

This single fine is close to the normal total of $8 million to $10 million in all fines that the Pipeline and Hazardous Materials Safety Administration hands out each year. But Third Coast has a stake in some 1,900 miles of pipelines, and in September, the Houston-based company announced that it had secured a nearly $1 billion loan.

Pipeline Safety Trust Executive Director Bill Caram said this spill “resulted from a company-wide systemic failure, indicating the operator’s fundamental inability to implement pipeline safety regulations,” so the record fine is appropriate and welcome.

“However, even record fines often fail to be financially meaningful to pipeline operators. The proposed fine represents less than 3% of Third Coast Midstream’s estimated annual earnings,” Caram said. “True deterrence requires penalties that make noncompliance more expensive than compliance.”

The agency said Third Coast didn't establish proper emergency procedures, which is part of why the National Transportation Safety Board found that operators failed to shut down the pipeline for nearly 13 hours after their gauges first hinted at a problem. PHMSA also said the company didn't adequately assess the risks or properly maintain the 18-inch Main Pass Oil Gathering pipeline.

The agency said the company “failed to perform new integrity analyses or evaluations following changes in circumstances that identified new and elevated risk factors” for the pipeline.

That echoed what the NTSB said in its final report in June, that “Third Coast missed several opportunities to evaluate how geohazards may threaten the integrity of their pipeline. Information widely available within the industry suggested that land movement related to hurricane activity was a threat to pipelines.”

The NTSB said the leak off the coast of Louisiana was the result of underwater landslides, caused by hazards such as hurricanes, that Third Coast, the pipeline owner, failed to address despite the threats being well known in the industry.

A Third Coast spokesperson said the company has been working to address regulators' concerns about the leak, so it was taken aback by some of the details the agency included in its allegations and the size of the fine.

“After constructive engagement with PHMSA over the last two years, we were surprised to see aspects of the recent allegations that we believe are inaccurate and exceed established precedent. We will address these concerns with the agency moving forward," the company spokesperson said.

The amount of oil spilled in this incident was far less than the 2010 BP oil disaster, when 134 million gallons were released in the weeks following an oil rig explosion, but it could have been much smaller if workers in the Third Coast control room had acted more quickly, the NTSB said.
