Nouryon Introduces Ingredient To Improve Battery Performance

Nouryon has begun the first deliveries of AkuPure, a carboxymethyl cellulose (CMC) polymer designed to improve the performance of lithium-ion batteries, which are skyrocketing in demand due to increased consumer interest in electric vehicles.

Nouryon says AkuPure is an ultra-high-purity CMC that improves the electrode coating process, making the battery more efficient by helping it to retain and deliver power more effectively. CMC is a sustainable polymer derived from cellulose sources such as wood or cotton that is used as a thickener, binder and rheology modifier in markets ranging from mining to pharmaceuticals.

“Customers in this market require ultrapure CMC [and] impurities can interfere with the performance of the battery or with production efficiency,” said Geert-Jan Beijering, Nouryon Product Director. “AkuPure has a number of properties key to the battery production process, such as the speed at which it dissolves and its low level of insolubles. The possibility to frequently charge and discharge a battery without losing performance under various temperature conditions is what matters most to our customers in this segment.”

“Our R&D team worked extremely hard to create a top-tier version of AkuPure, and this is the right time to bring this technology to market,” said Larry Ryan, Nouryon Americas Executive Vice President and President of Performance Formulations. “Demand for lithium-ion batteries continues to rise, and as battery manufacturers struggle to find CMC that meet the stringent demands of the industry, we are introducing a more advanced solution.”

Nouryon recently announced plans to acquire CMC business J.M. Huber Corporation, which the company hopes will significantly broaden its portfolio of CMC products.
