For decades, scientists have wondered what to do with the liquid inside a lithium-ion battery. This electrolyte is key to how batteries work, shuttling ions from one end of the cell to the other. But it’s also cumbersome, adding weight…

But stability remains a tough challenge.  In one recent study, published in Science in April, researchers discovered a new way to build perovskite solar cells with additives that improved efficiency and lifetime. The cells withstood…
