Co-simulation approach for analyzing electric-thermal interaction phenomena in lithium-ion battery
Battery thermal management for electric or hybrid vehicles is crucial to prevent overheating and uneven heating across a battery pack. Thus, this paper provides a reliable and accurate co-simulation approach that can predict the thermal state inside a battery pack by the electrochemical responses of lithium-ion (Li-ion) battery cells. The approach is based on coupling an electric circuit model and a Computational Fluid Dynamics (CFD) model. The effectiveness and validation of the simulation approach are discussed by comparison with the experimental data.
Abstract Aseptic loosening of implant is one of the main causes of Ti-based implant failure. In our previous work, a novel stable collagen/hyaluronic acid (Col/HA) multilayer modified titanium coatings (TCs) was developed by layer-by-layer (LBL) covalent immobilization technique, which showed enhanced biological properties compared with TCs that were physically absorbed with Col/HA multilayer in vitro. In this study, a rabbit model with femur condyle defect was employed to compare the osteointegration performance of them. Results indicated that Col/HA multilayer with favourable stability could better facilitate osteogenesis around implants and bone-implant contact. The Col/HA multilayer covalent-immobilized TC may reduce aseptic loosening of implant.
