After nearly a thousand charge and discharge cycles, the active substances inside lithium-ion batteries gradually lose their activity, leading to a decline in battery capacity and eventual disposal.

Ion exchange resin is a type of polymer that can exchange ions present in a solution. Ion exchange resins are widely used in various industries, such as water treatment, food and beverage, chemical, pharmaceutical, and environmental. Ion exchange resins can remove impurities, soften water, separate substances, and purify products.

Mixed bed resin refers to a mixture of a certain ratio of cation and anion exchange resins filled together in a single device, used for exchanging and removing ions in fluids. It is generally used for water with a low salt content or placed after reverse osmosis or EDI units to reduce the hardness, alkalinity, and both anions and cations in water, turning it into softened or deionized water.

In the realm of industrial chemical processes, phenolic compounds are indispensable. They serve as foundational raw materials and intermediates in the production of a myriad of products, from dyes and pesticides to adhesives and photographic developers.

Bipolar membranes represent a leap forward in ion exchange technology. These membranes are engineered by combining anion and cation selective layers with an intermediate interface layer. The unique structure of these membranes allows for the conversion of salts into their respective acids and bases when a reverse voltage is applied across the membrane. This process is facilitated by the migration of charged ions and the dissociation of water molecules at the membrane interface.

At the heart of our NMN separation expertise lies the SSMB Sequential Simulated Moving Bed Chromatography Device, a state-of-the-art instrument meticulously designed for unparalleled precision and efficiency. we believe that the right tools can make all the difference.

Our innovative approach begins with a special pretreatment of the solution. The molybdenum in the solution is selectively adsorbed onto our specially designed resin, leaving the tungsten in the post-adsorption solution. This method ensures a simple, efficient, and effective separation of the two metals, setting a new industry benchmark.

Sunresin's premium resins excel in eliminating impurities from the leaching solution, marking a significant reduction of TOC (residual P204, P507, sulfonated coal oil, etc.), COD (Chemical Oxygen Demand). This method is not only efficient but also environmentally conscious, ensuring no new impurities are introduced. The result? Enhanced economic value and benefits.
