In situ Raman microscopy of individual LiNi(sub 0.8)Co(sub 0.15)Al(sub 0.05)O(sub 2) particles in a Li-ion battery composite cathode
Article Abstract:
The local kinetic behavior of individual LiNi(sub 0.8)Co(sub 0.15)A1(sub 0.05)O(sub 2) particles toward Li(super +) intercalation-deinercalation in composite cathodes was studied in situ by Raman microscopy during electrochemical charge-discharge cycles in 1.2-M LiPF(sub 6) EC-EMC, 3:7 by volume. The local microphenomena are responsible for uneven performance of the cathode and lead to overall electrode impedance increase and contribute to the mechanism of lithium-ion cell failure.

Heating behavior and crystal growth mechanism in microwave field
Article Abstract:
A simple microwave solid-state reactor was designed, based on a domestic microwave oven, and the heating behavior of the reactor was studied to monitor the real-time temperature during irradiation. Results found that the temperature was related to the time and that microwave power depended on the duty cycle of microwave irradiation.

Microwave solid-state synthesis of LiV3O8 as cathode material for lithium batteries
Article Abstract:
A novel, and economical microwave route is developed for the synthesis of electrochemically active LiV3O8 material by using a domestic microwave oven. The heating behavior of the designed reaction system guided the preparation of LiV3O8 at a suitable irradiation power, reaction time, and temperature.
