Shengshimei launched a new technology to greatly improve the efficiency of lithium production

Sensmet has launched a new technology that significantly increases the efficiency of lithium production.

A breakthrough technology for lithium manufacturing

Sensmet has introduced a new technology that significantly increases the efficiency of lithium production – the most critical component of lithium-ion batteries. Sensmet’s automated in-line measurement technology enables optimal dosing of chemicals in lithium production, increasing revenue and reducing costs.

Traditionally, battery metals manufacturers have had to rely on batch sampling and laboratory analysis to control their processes, but this is expensive, labor-intensive and often results in delays of 4-10 hours. In contrast, Sensmet’s technology; Micro-Discharge Optical Emission Spectroscopy µDOES® is capable of real-time measurement of multiple metals such as any battery metal and its impurities. In addition to lithium manufacturing, the technology is also applicable to the recycling of “black lumps” of battery metals.

Implement stringent in-line monitoring and controls to reduce impurity levels, preventing cost and delays in reprocessing.

Potassiumeliber ran a pilot-scale test program in 2022 to evaluate the µDOES® analyzer for continuous optimization of dosing of precipitation chemicals during lithium production. Nearly 80 samples were extracted from the process and analyzed simultaneously for sodium and lithium concentrations using the µDOES® continuous analyzer and laboratory ICP-OES. The results show an excellent correlation between these methods.

Sami Heikkinen, caliber said:

Chemical dosing based on reliable real-time data brings stability to the process, which is important because it avoids drift and optimizes yield and quality while minimizing costs.

The ability to perform continuous, simultaneous measurements of multiple metals in aqueous matrices offers battery metals manufacturers the opportunity to increase process efficiency, reduce costs, increase yield, avoid waste, and improve final product quality.
