Introduction

If the internal combustion engine was the heart of the 20th-century automobile, the battery is the heart of the 21st-century electric vehicle. It accounts for 30-40% of the vehicle's value and determines its range, performance, and cost. As such, the battery has become a strategic asset, and control over its production has emerged as a central battleground in the global EV transition.

The competition is fierce. China currently dominates battery manufacturing, but the United States, Europe, Japan, and South Korea are investing billions to build their own capacity. At the same time, the battery industry faces immense sustainability challenges: the carbon footprint of production, water use in mining, and human rights abuses in cobalt supply chains. How these challenges are addressed will shape the environmental credentials of EVs and determine which companies and countries succeed.

This chapter examines the battery battleground. We explore the structure of the supply chain, the leading players, the sustainability issues, and the intense international competition for dominance. We also look at emerging technologies that could reshape the landscape. The battery is not just a component; it is a strategic asset at the center of a global power struggle.

The Battery Supply Chain: From Mine to Pack

The journey from raw material to finished battery pack involves several distinct stages, each with its own geography and competitive dynamics.
