Mangrove Lithium, a Vancouver based company, has developed a breakthrough platform for the most cost-effective production of battery grade lithium hydroxide and carbonate from diverse input streams and assets. Mangrove’s modular solution can be scaled to any capacity and co-located with upstream lithium producers or cathode and cell manufacturers. The platform technology is being commercialized for the conversion of waste brines to chemicals and desalinated water. The company recently attracted funding through Breakthrough Energy, BMW i Ventures, and BDC Capital and is working towards the deployment of a first-of-a-kind commercial plant.
