What Is a Sodium-Ion Battery, and Is It Good for an Electric Scooter?

A sodium-ion battery stores and releases energy using sodium ions instead of lithium. It works on the same principle as a lithium battery but swaps in sodium — an abundant, low-cost material — which makes it valued for stability, heat tolerance and cost. In the Evee range, the S1 Sodium-ion uses a 72V 33Ah sodium-ion pack.

What is a sodium-ion battery?

A sodium-ion (Na-ion) battery is a rechargeable battery that uses sodium ions to carry charge between its electrodes — the same basic idea as a lithium-ion battery, but with sodium in place of lithium. Sodium is one of the most abundant elements on earth, so the raw materials are cheaper and more widely available than lithium's.

What are the advantages of a sodium-ion battery?

Sodium-ion batteries are known for a few practical strengths:

• Stable and safe: the chemistry is generally very stable and tolerant of heat — useful in a hot climate.
• Abundant materials: sodium is cheap and plentiful, which helps keep costs down.
• Cold-weather behaviour: sodium-ion tends to hold up better than some lithium chemistries in low temperatures.

Are there any trade-offs?

The main trade-off has historically been energy density — early sodium-ion packs stored a little less energy for their size and weight than the best lithium packs, though the technology is improving quickly. In practice, the Evee S1 Sodium-ion delivers a solid 70–90 km range and a 4–5 hour charge, so for everyday city riding it behaves much like any modern electric-scooter battery.

Sodium-ion vs lithium vs graphene on an Evee

Evee now offers three battery types across its range:

• Graphene — the value choice; heavier, charges in about 7–8 hours, very heat-tolerant.
• Lithium — lighter, charges in about 4–5 hours, longer cycle life, premium price.
• Sodium-ion — a newer chemistry on the S1 Sodium-ion, charging in about 4–5 hours, built on abundant, stable materials.

Which Evee uses a sodium-ion battery?

The Evee S1 Sodium-ion (PKR 255,000) is the model built on a sodium-ion pack. You can see its full specs on the S1 Sodium-ion page.

Frequently Asked Questions (FAQs)

What is a sodium-ion battery?

A rechargeable battery that uses sodium ions instead of lithium to store energy — built on abundant, low-cost materials and known for being stable and heat-tolerant.

Is a sodium-ion battery good for an electric scooter?

Yes — it's stable, handles heat well, and on the Evee S1 Sodium-ion delivers a 70–90 km range with a 4–5 hour charge.

Which Evee has a sodium-ion battery?

The Evee S1 Sodium-ion, priced at PKR 255,000.

Is sodium-ion better than lithium?

Each has strengths: lithium packs more energy for its weight, while sodium-ion uses cheaper, abundant materials and is very stable. For daily city riding, both perform well.
