This work reviews different techniques available for the synthesis and modification of cathodeactive material particles used in Li-ion batteries. The synthesis techniques are analyzed in termsof processes involved and product particle structure. The knowledge gap in the process-particlestructure relationship is identified. Many of these processes are employed in other similarindustries; hence, parallel insights and knowledge transfer can be applied to battery materials.Here, we discuss examples of applications of different mechanistic models outside the batteryliterature and identify similar potential applications for the synthesis of cathode active materials.We propose that the widespread implementation of such mechanistic models will increase theunderstanding of the process-particle structure relationship. Such understanding will providebetter control over the cathode active material synthesis technique and open doors to the precisetailoring of product particle morphologies favorable for enhanced electrochemical performance.

The process of pressurized injection of ultra-fine powder extinguishing agents (UPEA) and the effect of injection from the nozzle directly affects the spatial dispersion characteristics and the effectiveness of fire extinguishing. Combining CFD simulations and experimental measurements, the UPEA pressurized injection process and injection effects were investigated. The transient process of injection is divided into three stages, initial injection stage, steady injection stage, and post-injection stage. The post-injection stage is divided into a slow decay process and a residual gas release process. Investigating the effect of different filling conditions on the effectiveness of particle injection. In the stable injection stage, the higher the filling ratio, the lower the mass flow of UPEA particles at the same filling pressure. At the same filling ratio, the higher the filling pressure, the higher the mass flow of UPEA particles. The maximum mass flow of the UPEA particles was 5.38 kg/s at a filling ratio of 20% and a filling pressure of 3.6 MPa. The steady injection time is mainly influenced by the particle filling ratio.

“…While simulations and experiments lacked close quantitative agreement, both showed a similar qualitative increase in strength with increasing binder contents. Calibration methods to obtain the bonding parameters of LPB model do not take account of the inherent physical properties of contacts and hence the ability to predict the correct outcome was limited (Dosta et al, 2016;Eckhard et al, 2017). The beam model provides a more realistic representation of bond mechanics.…”
