Sodium-ion (Na-ion) batteries use sodium ions instead of lithium ions to store and deliver power. Sodium is much more abundant and environmentally friendly than lithium, but there are still several challenges left to make sodium-ion batteries the new battery champion.
Batteries are becoming crucial to everyday life, and whoever comes up with a better battery has the world on a platter. Sodium-ion batteries are a top contender to the crown held by lithium-ion batteries, but what exactly makes them special?
What Is a Sodium-Ion Battery?
Sodium-ion batteries are batteries that use sodium ions (tiny particles with a positive charge) instead of lithium ions to store and release energy. Sodium-ion batteries started showing commercial viability in the 1990s as a possible alternative to lithium-ion batteries, the kind commonly used in phones and electric cars.
How Sodium-Ion Batteries Work
Sodium-ion batteries, also called Na-ion batteries, use a chemical reaction to store and release electrical energy. Like all batteries, they have two electrodes (a positive electrode and a negative electrode) separated by an electrolyte, which is a special substance that…
