Electrochemical studies on mixtures of LiNi0.8Co0.17Al0.03O2 and LiCoO2 cathode materials for lithium ion batteries

Highly Oriented Growth of Pulsed-Laser Deposited LiNi0.8Co0.2O2 Films for Application in Microbatteries

“…There is a constantly increasing demand for miniaturized high energy density batteries to power microsystems such as microsensors, smart cards, implantable medical devices, intelligent labels, and so on. , The tremendous recent interest in the development of solid-state rechargeable lithium microbatteries has generated a strong interest in synthesis and characterization of transition metal oxides in view of their potential application as cathode materials. − Several transition metal oxides such as LiCoO 2 , LiNiO 2 , LiMn 2 O 4 , and their derivatives have been considered and extensively studied in recent years. − Following the early discovery of lithium intercalation properties by Goodenough et al, LiCoO 2 has been exploited and is currently the material employed in commercially available rechargeable batteries. ,, However, LiCoO 2 is expensive and toxic. Only 50% of the theoretical capacity could be utilized in the voltage range of 3−4.25 V. Furthermore, LiCoO 2 undergoes a lattice expansion, during charging, along the c axis and the oxygen is expelled out from the lattice as a result of the interaction of the electrode surface with electrolyte .…”

Review on Synthesis, Characterizations, and Electrochemical Properties of Cathode Materials for Lithium Ion Batteries

“…In lithium iron fluorophosphate, one Li + can be cycled charge/discharge with the theoretical capacity of 153 mAh/g [222][223][224][225] [236][237][238][239][240]. Then reported by the Sauvage [213], who prepared in the tavorite type structure LiFePO 4 OH.…”
