Synergetic effects of blended cathode active materials: Simulation and Experiment |
| 초록 |
In the quest to achieve a higher capacity electrode materials for lithium ion batteries, different active materials for both cathode and anode are being studied. However, the available electrode materials which have been discovered have both good and bad sides. Hence, the electrochemical characteristics of Li-ion cells made of blended cathode material composed of LiMn2O4 and LiNi0.6Co0.2Mn0.2O2 and an artificial graphite anode are being studied via both experiments and simulation. The cycle performance of the two pure cell chemistries we modelled by considering Mn2+ dissolution in the cathode and solid electrolyte interphase information in the anode. By fitting our model predictions to the experimental data, the percentage of each contributing factor to the total capacity fade was determined. Ragone plots were used to study the correlation between the energy density and average specific power of the two pure chemistries and their blends. |
