Abstract:

Electrification in the transportation sector is an emerging trend and battery technology plays the critical role in this revolutionary transformation. The EV application requires the batteries having high energy, high power, robust, long life, and low cost towards specific USABC targets. Unfortunately, the conventional electrode materials and chemistries cannot fulfill the need for electric vehicle usage. Therefore, the development of novel advanced electrochemical energy storage systems is essential to achieve the requirement of batteries for different types of EV applications. This talk will discuss the current status and challenge of silicon or silicon-based Li-ion batteries, Li-S or Li metal based batteries, and high energy density hybrid type supercapacitors. Although there are already major progresses made in the development of each one of the areas during past few years, the performance of such materials and systems can be significantly influenced by many factors, both at the materials and the electrodes level. This talk will further address the parameters that impact both the performance and the cell level energy densities, which include the binders, the electrolytes, the additives, the active material loadings, etc.
