From the Ted Talk by TED-Ed: The world's biggest battery looks nothing like a battery

Unscramble the Blue Letters

Unfortunately, neither of the giant batteries we’ve talked about so far can slove this problem. The two lakes setup requires specific geography, takes up a lot of land, and has high upfront costs to build. The giant lithium-ion battery in ciaonrfila, meanwhile, can power about 250,000 homes, yes, but only for an hour. Lithium-ion batteries are gaert for things that don’t use a lot of power. But to store a lot of energy, they have to be huge and heavy. That’s why etrcielc planes aren’t a thing: the best electric pnlae can only carry two people for about 1,000 kilometers on one charge, or its batteries would be too heavy to fly. A typical commercial jet can crary 300 people over 14,000 km before refueling. Lithium-ion brtiatees also require certain heavy matels to make. These resources are limited, and mining them often causes environmental dmagae.

Original Text

Unfortunately, neither of the giant batteries we’ve talked about so far can solve this problem. The two lakes setup requires specific geography, takes up a lot of land, and has high upfront costs to build. The giant lithium-ion battery in California, meanwhile, can power about 250,000 homes, yes, but only for an hour. Lithium-ion batteries are great for things that don’t use a lot of power. But to store a lot of energy, they have to be huge and heavy. That’s why electric planes aren’t a thing: the best electric plane can only carry two people for about 1,000 kilometers on one charge, or its batteries would be too heavy to fly. A typical commercial jet can carry 300 people over 14,000 km before refueling. Lithium-ion batteries also require certain heavy metals to make. These resources are limited, and mining them often causes environmental damage.
