Despite the utility of ceramic and PFSA membranes in preventing capacity fade, their high component cost and processing challenges has prevented penetration of Li-S technology into the marketplace. Introduction of Berkeley Lab’s low-cost PIM Membranes for Long-Lived Li-S Batteries is a game changer for Li-S battery commercialization, which is why it won a 2016 R&D 100 award.
The performance metrics of PIM membranes match or exceed incumbent membranes in all categories including conductivity, processability and stability. PIM membranes operate by an unconventional nano-sieving mechanism adding novelty to the candidate invention. The economic benefits of deploying Li-S batteries that incorporate Berkeley Lab’s membranes are clear: rechargeable Li-S batteries reduce the cost of electrochemical energy storage three-fold. The environmental benefits are likewise clear: sulfur is a by-product of the oil industry; its use obviates the need for toxic and expensive heavy metals. Li-S batteries are safe and thus attractive for behind-the-meter storage.
Each year for more than 50 years, R&D Magazine has honored the 100 best innovations in research and development. We are currently accepting applications for the 2017 R&D 100 Awards. Innovators with an exceptional product developed between January 1, 2016 and March 31, 2017 should apply. Submissions close April 14, 2017
