Revolutionary Energy Storage: NASA’s Sulfur Selenium Solid-State Battery Innovation
"higher energy density 2X or 3X that of lithium so operate longer between charges with longer overall lifespan, more abundant than lithium, cobalt, nickel... solid minimizes leakage/ thermal runaway, allows greater operating temperature range... hurdles: selenium copper refining byproduct so could lead to supply constraints, can be toxic in high concentrations, ensuring material purity, developing cost-effective manufacturing... also useful in space for long flights and extreme conditions"
