Exploring the Future of Sodium-Ion Batteries

Introduction
Batteries play a crucial role in our modern world, but their costs have been a major barrier to widespread adoption. While lithium-ion batteries have been dominant, they are still relatively expensive, limiting their use in applications like home energy storage. To address this issue, manufacturers are now turning to sodium-ion batteries as a potential alternative or complement to lithium-ion.
Understanding Sodium-Ion Batteries
- Sodium-ion batteries offer a more affordable option compared to lithium-ion due to the lower cost of raw materials.
- However, current sodium-ion batteries are less energy-dense, making them unsuitable for electric vehicles.
- Batteries made with sodium-ion require different charging and discharging mechanisms, necessitating new electronics.
