Lithium Batteries: Current State and Beyond
Rechargeable lithium-ion batteries were first commercialized by Sony in early 90’s. The high cost of
cobalt and relatively low specific capacity of LiCoO2 (140Ah/kg) have been major obstacles against
the application of these batteries in transportation where the battery energy density should significantly
increase to meet the goals for plug-in hybrid vehicles (PHEVs), and essentially for electric vehicles
(EVs). Also, despite the abundance of iron and manganese, olivine LiFePO4 and spinel LiMn2O4 will
not likely be adequate candidates since neither of them can provide enough gravimetric and volumetric
energy densities for transportation applications. Therefore, research groups have been under the
challenge of inventing and developing new advanced positive electrode materials whose main
characteristics is to store more and more electricity per mass and volume. Of these materials, advanced
composite materials were found to deliver a high reversible capacity (250Ah/kg) while being
structurally and electrochemically stable upon charge and discharge. These thermally stable materials
are considered as potential candidates to surmount the energy density shortfall of current lithium ion
batteries. The journey for materials design and discovery will be unveiled in the light of the most
recent developments in lithium-ion batteries. Also, the implementation of the very challenging lithiumsulfur and lithium-air batteries will be discussed.
