Why is Lithium Used Instead of Na for Battery Technology?

If you’re wondering why lithiun is used instead of na in batteries, you’re not alone. Hundreds of battery manufacturers worldwide use lithiun in their cells. Both materials have similar chemistries. While sodium is more commonly used, its weaknesses have been well known for decades. Engineers may also have been able to use the similarities between these materials in their chemistry to solve practical problems before they release new batteries.
