Lithium-ion battery manufacturing for electric vehicles produces significant emissions of sodium sulphate. By 2032, it is estimated that eight to twelve million tonnes of sodium sulphate will be produced annually. Currently, there is no large-scale solution for this liquid effluent, which could slow the transition to electrification.
Enabling sustainability in lithium battery manufacturing through circular processing.
NESI’s innovation eliminates liquid effluent, reduces greenhouse gas emissions, and enables a circular economy for battery metal refining and recycling worldwide. Using electrochemical salt-splitting, NESI converts the liquid effluent waste from traditional lithium refining, manufacturing, and recycling processes into valuable chemicals with the NORSCAND® Electrolyser. This process ensures production with minimal environmental footprint, and can potentially eliminate up to 22 million tonnes of CO2 emissions annually.
NorthX’s funding will support NESI in validating Ionomr’s ionic membrane technology for the industrial-scale electrochemical regeneration of sodium sulfate effluent from lithium-ion battery manufacturing.
