Challenges of sodium-ion batteries for EVs:Lower energy density:...

Challenges of sodium-ion batteries for EVs:

• Lower energy density: Sodium ions are larger and heavier than lithium ions, which means that sodium-ion batteries can store less energy per unit weight and volume. This makes sodium-ion batteries less suitable for applications where space and weight are at a premium, such as EVs.

• Shorter cycle life: Sodium-ion batteries typically have a shorter cycle life than lithium-ion batteries. This means that sodium-ion batteries will need to be replaced more often, which could increase the overall cost of EVs.

• Slower charging: Sodium-ion batteries typically charge more slowly than lithium-ion batteries. This means that sodium-ion batteries could take longer to charge, which could be inconvenient for EV owners.
