Abstract
Li-ion batteries (LIBs) are known to be one of the primary power sources for energy storage andconversion devices, including portable electronics and electric vehicles. State-of-the-art LIBsmanufacturing process is largely seeking advanced electrode production method with minimumenvironmental concern. Current manufacturing method is based on slurry casting process where atoxic solvent N-methyl pyrrolidone (NMP) is used. NMP is declared as a priority substance in USAunder the Toxic Substance Control Act (TSCA) for having “unreasonable risk” and requires immediateregulatory action. Thus, sustainable fabrication of slurry-based electrode involving greener alternativeof NMP is needed urgently to mitigate risks to both environment and workers. Likewise, wide range ofLIBs use increases the risk of large number accumulation of spent LIBs. There is a serious environmentpollution threat, if the end-of-life batteries are disposed without proper recycling. Till today efforts torecycle LIBs have primarily focused on energy intensive pyrometallurgy, hydrometallurgy processesalong with use of toxic NMP. Sarkar Research Group recently developed an advanced cathodemanufacturing method and direct cathode recycling design using two green organic solvents,alternatives of toxic NMP. In this presentation, I will elaborate our research finding.
