Japanese electronics company Toshiba has developed a new kind of cobalt-free battery that could lead to cheaper, more sustainable EVs in the future.
The challenge: Road transportation is a significant contributor to climate change, accounting for 12% of global greenhouse gas emissions, so transitioning from fossil fuel-powered cars and trucks to electric vehicles (EVs) is crucial to meeting our climate goals.
The lithium-ion batteries used in most of today’s EVs have several problems, though, and a big one is that their cathodes are made of cobalt, a rare and expensive metal often mined using child labor and environmentally destructive practices.
