“…[314][315][316] On the other hand, Olivine LiFePO 4 has been considered a promising cathode material for large scale lithium-ion batteries used for hybrid electric vehicles (HEVs) or electric vehicles (EVs). 283,288,292,[317][318][319][320][321][322][323][324][325][326][327] The material has low toxicity, potential for low cost, long cycle ability and high safety. In the early stage of LiFePO 4 research, many reported that the rate performance of LiFePO 4 was greatly limited by the slow diffusion of lithium ion in LiFePO 4 , and/or the low electronic conductivity.…”

Over the past decades, there have been many projections on the future depletion of the fossil fuel reserves on earth as well as the rapid increase in green-house gas emissions. There is clearly an urgent need for the development of renewable energy technologies. On a different frontier, growth and manipulation of materials on the nanometer scale have progressed at a fast pace. Selected recent and significant advances in the development of nanomaterials for renewable energy applications are reviewed here, and special emphases are given to the studies of solar-driven photocatalytic hydrogen production, electricity generation with dye-sensitized solar cells, solidstate hydrogen storage, and electric energy storage with lithium ion rechargeable batteries.

The hierarchical-structured LiFePO4 cathode materials were synthesized by one-step microwave synthesis, and their electrochemical properties were investigated. Addition of citric acid during the reaction lead to the formation of hierarchical structured LiFePO4, which has both nano-and micron-characteristics advantageous for energy density and electrode fabrication. Adjusting the molar ratio of Fe to citric acid enhanced the electrochemical properties of LiFePO4.

“…9 Additionally, LiFePO 4 has poor electronic conductivity (about 10 ) because the corner-shared FeO 6 octahedra are separated by the oxygen atoms of the PO 4 3− tetrahedra and cannot form a continuous FeO 6 network. 10,11) To address these problems, many researchers suggested methods such as coating with conductive carbon, 8) refining the particle size, 12) and doping of supervalent cations (such as Zr, Ti, Nb, and Mg).…”

:Over the past few years, LiFePO 4 has been actively studied as a cathode material for lithium-ion batteries because of its advantageous properties such as high theoretical capacity, good cycle life, and high thermal stability. However, it does not have a very good power capability owing to the low lithium-ion diffusivity and poor electronic conductivity. Reduction in particle size of LiFePO 4 to the scale of nanometers has been found to dramatically enhance the above properties, according to many earlier reports. However, because of the intrinsically low tap density of nanomaterials, it is difficult to commercialize this method. Many studies are being carried out to improve the volumetric energy density of this material and many methods have been reported so far. This paper provides a brief summary of the synthesis methods and electrochemical performances of microspherical LiFePO 4 having high volumetric energy density.
