Cobalt is criticized in batteries for several reasons, primarily ethical and environmental. Ethically, the majority of the world's cobalt comes from countries with poor labor standards, leading to concerns over exploitative practices, including child labor. Environmentally, cobalt mining is linked to significant ecological damage, including water pollution and habitat destruction. Although cobalt enhances battery performance by increasing energy density and extending life, these serious social and environmental issues have spurred research into cobalt-free battery technologies.
