Sodium Steals the Spotlight: New Research Heats Up Race for Next-Gen Batteries
Lithium-ion batteries have revolutionized our world, powering everything from smartphones to electric vehicles. But concerns about lithium scarcity, mining impacts, and potential safety hazards are driving the search for alternatives. Enter sodium-ion batteries, a promising technology with the potential to steal the crown. Why Sodium? Sodium boasts several advantages over lithium. It's abundant, naturally occurring, and significantly cheaper. Plus, sodium-ion batteries offer inherent safety benefits due to their non-flammable nature. They can also function at wider temperature ranges, making them ideal for extreme climates. Recent Breakthroughs: Researchers are making significant strides in overcoming sodium-ion's historical limitations, such as lower energy density compared to lithium-ion. Here are some exciting developments: Northvolt's milestone: This Swedish company unveiled a sodium-ion battery with an energy density of 160 Wh/kg, comparable to entry-level li...
