Lithium Ion is more advanced battery technology because it's got high energy density which means it's used in consumer electronics. Lower energy density technologies exist with better properties for storing at grid scale. They're heavier and bigger than lithium ion batteries, but can store energy a lot longer and use much more available materials. One example is Form Energy's Iron/Air battery, which uses rusting iron to store electricity for hundreds of hours.
