Are lithium-ion batteries the future of energy storage?

As the world increasingly swaps fossil fuel power for emissions-free electrification, batteries are becoming a vital storage tool to facilitate the energy transition. Lithium-Ion batteries first appeared commercially in the early 1990s and are now the go-to choice to power everything from mobile phones to electric vehicles and drones.

Are lithium-ion batteries sustainable?

We introduce the notion of sustainability through discussion of the energy and environmental costs of state-of-the-art lithium-ion batteries, considering elemental abundance, toxicity, synthetic methods and scalability. With the same themes in mind, we also highlight current and future electrochemical storage systems beyond lithium-ion batteries.

Could lithium batteries be cheaper and greener?

Lithium batteries are very difficult to recycle and require huge amounts of water and energy to produce. Emerging alternatives could be cheaper and greener. In Australia's Yarra Valley, new battery technology is helping power the country's residential buildings and commercial ventures – without using lithium.

Why do lithium-ion batteries need to be recycled?

"Recycling a lithium-ion battery consumes more energy and resources than producing a new battery, explaining why only a small amount of lithium-ion batteries are recycled," says Aqsa Nazir, a postdoctoral research scholar at Florida International University's battery research laboratory.

Are lithium-ion batteries a resource problem?

The resource question is an important one. Although lithium-Ion batteries contain a very small amount of lithium, the predicted growth of demand for these batteries could put pressure on supply chains for materials like lithium, nickel, cobalt, manganese and graphite. And it’s essential that supply chains operate in an ethical way.

Why are lithium-ion batteries important?

They are also needed to help power the world’s electric grids, because renewable sources, such as solar and wind energy, still cannot provide energy 24 hours a day. The market for lithium-ion batteries is projected by the industry to grow from US$30 billion in 2017 to $100 billion in 2025.
