Lithium ion batteries as a power source are dominating in portable electronics,
penetrating the electric vehicle market, and on the verge of entering the utility
market for grid-energy storage. Depending on the application, trade-offs among
the various performance parameters-energy, power, cycle life, cost, safety, and
environmental impact-are often needed, which are linked to severe materials
chemistry challenges. The current lithium ion battery technology is based on
insertion-reaction electrodes and organic liquid electrolytes. With an aim to
increase the energy density or optimize the other performance parameters, new
electrode materials based on both insertion reaction and dominantly conversion
reaction along with solid electrolytes and lithium metal anode are being
intensively pursued. This article presents an outlook on lithium ion technology
by providing first the current status and then the progress and challenges with
the ongoing approaches. In light of the formidable challenges with some of the
approaches, the article finally points out practically viable near-term
strategies.
