The properties of rubber have allowed it to be utilized across many different industries. One of the industries that use rubber is the tire industry. The rubber used in tires affects the performance of the vehicle such as its fuel consumption and safety. Hence, study on tire performance becomes important from different aspects. This study will look at the calculation of the friction coefficient of tire rubbers, which affects vehicle safety, based on studies conducted by different research groups. By combining different models, we suggest a new simple model to predict the friction coefficient. Several discussions in the article will be for validation of the model and its range of applications. We then implement a parametric analysis to determine which factors critically affect the friction coefficient. By finding the sensitivity of the inputs of the model/ code, the critical factors can be identified and focused on. The parameters that are studied are the storage modulus, loss modulus, surface asperities heights, the surface asperities wavelength, and the adhesive contribution to friction. The adhesion and hysteresis contributions to the friction coefficient are also discussed in this article. It is shown that the adhesive contribution plays a large role in determining the friction coefficient.

All-solid-state lithium batteries (ASSLBs) using argyrodite electrolyte materials have shown promise for applications in electric vehicles (EVs). However, understanding the effects of processing parameters on the ionic conductivity of these electrolytes is crucial for optimizing battery performance and manufacturing methods. This study investigates the influence of electrolyte operating temperature, electrolyte operating pressure, electrolyte pelletization pressure, and electrolyte pelletizing temperature on the ionic conductivity of the Li6PS5Cl0.5Br0.5 argyrodite electrolyte (AmpceraTM, D50 = 10 µm). A specially designed test cell is employed for the experimental measurements, allowing for controlled pelletization and testing within the same tooling. The results demonstrate the significant impact of the four parameters on the ionic conductivity of the argyrodite electrolyte. The electrolyte operating temperature has a more pronounced effect than operating pressure, and pelletizing temperature exerts a greater influence than pelletizing pressure. This study provides graphs that aid in understanding the interplay between these parameters and achieving desired conductivity values. It also establishes a baseline for the maximum pelletizing temperature before undesirable degradation of the electrolyte occurs. By manipulating the pelletizing pressure, operating pressure, and pelletizing temperature, battery engineers can achieve the desired conductivity for specific applications. The findings emphasize the need to consider operating conditions to ensure satisfactory low-temperature performance, particularly for EVs. Overall, this study provides valuable insights into processing and operating conditions for ASSLBs utilizing the Li6PS5Cl0.5Br0.5 argyrodite electrolyte. [ABSTRACT FROM AUTHOR]
