Low temperature ionothermal synthesis of LiFeSO4F cathode material for lithium-ion battery
Li-ion batteries have contributed to the commercial success of portable electronics, and are now in a position to influence higher-volume applications such as plug-in hybrid vehicles.

Explaining Lithium-ion Chemistries
Li-ion batteries come in many varieties but all have one thing in common — the catchword “lithium-ion.” Although strikingly similar at first glance, these batteries vary in performance, and it’s mostly the cathode material that gives then their unique personality.

A comparative study of Lithium-Ion Batteries
Current lithium ion battery technology is ready to revolutionize hybrid vehicles. Lithium iron phosphate batteries produced by A123 offer almost twice the specific energy than that of nickel metal hydride batteries used in current hybrid vehicles.

Chemical State of Iron of LiFePO4 during Charge-Discharge Cycles Studied by In-Situ X-ray Absorption Spectroscopy
In-situ X-ray absorption spectroscopy (XAS) at the Fe K-edge X-ray absorption near edge was used to investigate the chemical change of LiFePO4, which is a candidate cathode material for lithium ion batteries, during charge-discharge cycles. The relative amount of FePO4 formed in the LiFePO4 by the charge-discharge cycles was estimated from the XAS spectra.
