Recycling of Ternay Precursor By-product
Transforming Ternary Precursor Waste with Bipolar Membrane Technology
Ternary precursor is crucial for ternary cathode production, linking non-ferrous and lithium battery materials.
Industry output reached 334,000 tons in 2020 and is projected to reach 2 million tons by 2025.
Each ton of precursor yields 1.6-1.8 tons of sodium sulfate, posing disposal challenges.
Lanran's bipolar membrane technology converts sodium sulfate into reusable sulfuric acid and sodium hydroxide.
