sODIUM-ION BATTERY
A sodium-ion battery is a type of rechargeable battery that uses sodium ions (Na⁺) as the charge carriers instead of lithium ions. It operates similarly to lithium-ion batteries but uses more abundant and cost-effective materials. Sodium-ion batteries are considered safer, more environmentally friendly, and better suited for large-scale energy storage applications. They typically have slightly lower energy density but offer good thermal stability and long cycle life. This technology is emerging as a promising alternative for grid storage, electric vehicles, and portable electronics.
