  "textContent": "Lithium-ion batteries dominate the market for large-scale energy storage today. However, the element's uneven global distribution and rising costs are driving the search for alternatives. Sodium is roughly a thousand times more abundant in Earth's crust and can be extracted from seawater, making sodium-ion batteries a compelling option for grid-scale storage where cost and supply security are paramount.",
