hydroxide recovery project at a battery company, showing the treatment scale and operating indicators of this technical route in similar projects.<\/p>\n<h2>Key indicators<\/h2>\n<ul>\n<li>Treatment capacity: 80m3\/d<\/li>\n<li>Total homogeneous membrane area: 968m2<\/li>\n<li>Bipolar membrane area: 484m2<\/li>\n<\/ul>\n<h2>Project background<\/h2>\n<p>The production process for lithium battery materials generates lithium salt-containing solutions and wastewater, and as a high-value element, lithium provides a strong incentive for recovery.<\/p>\n<p>The traditional causticization method for preparing lithium hydroxide requires the addition of alkali agents and generates by-products, resulting in a relatively long process flow.<\/p>\n<p>The project aims to use an electrically driven method to convert lithium salt directly into lithium hydroxide while producing acid that can be reused.<\/p>\n<h2>Process route<\/h2>\n<ul>\n<li>Bipolar membrane electrodialysis (BMED) is adopted, with bipolar membranes and homogeneous membranes alternately assembled to form the membrane stack.<\/li>\n<li>Hydroxide ions generated by water dissociation in the bipolar membrane combine with lithium ions to form a lithium hydroxide solution.<\/li>\n<li>Anions in the feed liquid combine with hydrogen ions to form the corresponding acid, which can be returned to the upstream process for use.<\/li>\n<li>Electricity is used as the driving force instead of chemical agent addition, simultaneously reducing by-product salt and chemical consumption.<\/li>\n<\/ul>\n<h2>Configuration scale<\/h2>\n<ul>\n<li>Treatment capacity: 80 m\u00b3\/d.<\/li>\n<li>Homogeneous membrane area: 968 m\u00b2.<\/li>\n<li>Bipolar membrane area: 484 m\u00b2.<\/li>\n<\/ul>\n<h2>Illustrative
