Abstract
In the recent years, electric vehicles (EV) have seen a sharp increase in the automotive industry due to their significant benefit of zero emission and driving experience. However, in order to generate enough electric power, an EV often includes thousands of cells installed in the power battery. The connection of an EV power battery involves a hierarchical setup: thousands of individual cells are connected to form modules, which then link together to create the main traction pack. These connections must be extremely robust in order to endure constant vibrations, extreme temperatures and the transfer of high-voltage power. Advanced welding technologies, such as laser welding and ultrasonic welding, which offer high strength and production efficiency, are therefore adopted to join the tabs, electrodes, wires and busbars composed of copper and aluminum in the EV power battery. Experimental and computational methods were used to study the laser welding and ultrasonic welding processes for copper-to-copper, aluminum-to-aluminum, and aluminum-to-copper sheets. The mechanical performance of the welds was evaluated based on their tensile strength, hardness distribution, failure mode and fatigue life. The failure process and failure mode of welds in quasi-static tensile tests were investigated using finite element models of welds with a non-homogeneous material design and a ductile damage criterion. Life estimations of welds in fatigue tests were obtained using the global and local stress intensity factor solutions of welds and the Paris law. The computational results showed good agreement with the experimental ones.

Abstract
Agricultural waste is often perceived as a burden, yet it holds remarkable potential to shape a more sustainable future. By reimagining paddy straw as a valuable resource, we can create innovative pathways that connect renewable energy with sustainable manufacturing. This keynote will highlight how science and creativity converge to transform waste into nanocellulose, a material that embodies strength, lightness, and environmental responsibility.
Nanocellulose is more than a scientific achievement. It represents a vision of how renewable materials can power next-generation energy storage systems while advancing the principles of the circular economy. The journey from discarded residue to high-performance supercapacitors illustrates how sustainability and technology can work together to reduce waste, generate value, and inspire a more resilient world.
