One of the challenges with capturing green solar energy is in being able to store that energy for use in times when the sun is unavailable. While the cost of harvesting solar energy has declined significantly in recent years, the cost to store that energy via battery packs and other methods hasn’t come down as quickly. Researchers from Cornell have been exploring low-cost materials to create rechargeable batteries to make energy storage more affordable.

The team believes their breakthrough could provide a safer and more environmentally friendly alternative to lithium-ion batteries dominating the battery market currently. Lithium-ion batteries do have some challenges, including that they are slow to charge and could catch fire if punctured or damaged. In their current research, scientists are using
