When Sony first commercially introduced lithium-ion batteries in 1991, the industry recognized their potential to revolutionize portable electronics. Ever since, there have been countless efforts to improve the technology, with many researchers focusing on energy density and longevity, in line with demand from emerging applications such as electric vehicles (EVs) and on-grid energy storage. Julian Jansen and Youmin Rong of IHS Markit discuss the effect of safety concerns on this rapidly growing global market.
