X-MAT, the advanced materials division of Semplastics, recently announced it has been granted a United States patent for its electrode fabrication technology, which dramatically increases the storage capacity of graphite recovered from recycled batteries.
"What we are doing with recycled electric vehicle batteries is unique and revolutionary and the patent proves it," said Semplastics CEO Bill Easter.
The patent covers several important technologies that incorporate recycled or contaminated materials from EV or consumer electronic lithium-ion batteries into high-performance anode composites that can be reintegrated back into the supply chain.
This includes graphite and other materials that have reached end-of-life or come from production scrap generated from the battery manufacturing process.
X-MAT's battery research laboratory, X-BATT, has developed a patented technology to nearly double the capacity of battery-grade graphite by coating the recycled graphite in a special formula.
"The granting of this patent is an important milestone for X-BATT," continued Easter. "We have invested heavily in growing our IP (intellectual property) portfolio and the development of this material science breakthrough over the last couple of years."

X-BATT has successfully utilized this patented technology across various contaminated materials. With the help of the Battery Innovation Center, a collaborative initiative to accelerate battery technology innovations, X-Batt has also demonstrated and validated significant performance improvements in single-layer pouch cells.
After developing its innovative electrode technology to serve as a solution for reusing recycled graphite from scrapped lithium-ion batteries, the collaboration with BIC has further advanced and validated the technology.
"I expect that we will be able to use this technology to make a lasting impact across the lithium-ion battery industry especially as the demand for electric vehicles continues to grow," said Easter.
