類別期刊論文
摘要A lithium ion battery is developed using fiber-type Li-rich cathode and carbon anode materials. The cathode material is synthesized onto the carbon fiber by a two-step reaction process, namely, the electrodeposition for forming the precursor and the hydrothermal treatment for synthesizing the active material. The active material layer is composed of nanoparticles, which can be identified as a 94.8 wt.% primary Li2MnO3 phase together with a 5.2 wt.% minor Li4Mn5O12 phase based on a synchrotron X-ray diffraction analysis. This cathode possesses a typical irreversible capacity during the first charge/ discharge cycle, which can be utilized to compensate for the anode one, enabling the full cell to work without an initial predoping. In addition, the cell exhibits a rapid activation, favorable coulomb efficiency and high-rate performance, suggesting that the fiber-type electrodes are structurally beneficial for the electrical conduction and ion diffusion. On the other hand, its discharge capacity fades with cycling, which can be attributed to the phase transformation from the layered Li2MnO3 to the spinel LiMn2O4.

類別期刊論文
摘要An approach is proposed to evaluate the VC effect in a LiFePO4/graphite cell at 60 °C through liquid chromatography mass spectrometry (LC-MS) together with direct analysis in real time mass spectrometry (DART-MS). The LC-MS result shows that VC can effectively suppress the formation of phosphate esters as well as carbonate oligomers during the electrochemical cycling. It is also known from DART-MS analysis that VC assists the formation of thermally resistant oligomeric phosphate ester layer on the graphite surface, storing more solvent EC inside the layer. On the other hand, no compounds are observed on the LiFePO4 cathode surface. The formation of the denser oligomeric phosphate ester layer is found to be the reason for the improved cycle stability of the cell cycled at elevated temperature.

類別期刊論文
摘要The thermal stability, in terms of cycle and rate performances at 80 C, and its safety related to lithium ion batteries composed of a LiFePO4 cathode and SiO anode are investigated. Based on an STEM-EELS analysis, the SiO powder is found to have an amorphous structure, in which nanosized Si particles (Sirich phase) are uniformly dispersed in the SiO2 matrix (SiO2-rich phase). During the charge/discharge cycling, the cell exhibits a satisfactory cycle performance with a discharge capacity retention of 93.6% and a voltage retention of 93.9% at the 1500th cycle. Also, the charge and discharge capacity retentions at 10 C are 97.5% and 94.7%, respectively, together with a limited polarization, demonstrating its high rate performance. Furthermore, a 1.16 Ah LiFePO4/SiO laminated cell shows negligible voltage and temperature changes during the nail penetration test. The Li concentration in the active material (Si-rich phase) is found to be almost the same as that in the SiO2-rich phase after the test. This high thermal stability and safety may be due to the formed layer from the SiO2 matrix, preventing any side reaction from occurring on the Si surface and isolating the internal current path during the nail penetration.
