This book begins with an overview of the manufacturing, particularly joining processes used predominately in lithium-ion battery and battery electric vehicles. The rest of the book then focuses on the theories, methods and recent advances in battery ultrasonic welding, the detailed conclusions of which are included in each chapter. Each chapter focuses on a specific topic related to the battery ultrasonic welding process or system using either a physics-based or data-driven approach. In summary,

Chapters 2 and 3 start with the definition of ultrasonic weld quality followed by a discussion of post-weld attributes and weld qualities. Two complementary quality metrics...
