Power Your Ride.
Without the Fire Risk.
Sodium-ion battery packs engineered for e-bikes and scooters — lighter, safer, and cheaper — built on our own electrolyte and cell technology.
Cobalt-free · Lithium-free · Engineered in-house.
Built for real-world micromobility
Safer chemistry
No lithium fire narrative hanging over the product.
Cold-proof operation
Designed to keep working when winter hurts other packs.
OEM-ready integration
Pack, cells, and chemistry engineered as one system.
Supply chain resilience
No cobalt. No lithium bottleneck. No borrowed chemistry.
The problem
E-bike batteries shouldn't be a safety gamble.
Lithium-ion packs power most of today's bikes and scooters — but they come with real costs: bulky packaging, thermal runaway risk, poor cold-weather performance, and dependence on scarce mined materials like cobalt and lithium.
We built TaiSan to fix this from the chemistry up.
Pain point
Fire risk headlines
A pack failure damages trust in the whole vehicle.
Pain point
Cold-weather drop-off
Range and power should not disappear with temperature.
Pain point
Heavy, bulky design
Battery packaging should not dictate the entire vehicle.
Pain point
Scarce material reliance
Supply security matters as much as performance.
The solution
A different battery, from the inside out.
Most “sodium battery” sellers just assemble cells they buy from someone else. We don't. Our packs are built around our own electrolyte formulation and our own cell design — which means we control safety, performance, and quality at the level that actually matters.
When the chemistry is ours, the advantages are real and repeatable, not borrowed.
Key benefits
Why sodium-ion is the smarter chemistry for two wheels.
Dramatically safer
Our sodium-ion chemistry is engineered to resist thermal runaway, reducing the failure risk that makes riders and manufacturers nervous with lithium packs.
Cleaner and more abundant
Built without cobalt or lithium, using a chemistry based on more abundant raw materials and a less fragile global supply chain.
Long cycle life
Designed for thousands of charge cycles so the pack stays useful for longer, lowers cost per kilometre, and fits fleet economics better.
Fast, forgiving charging
Quick top-ups with a chemistry built to tolerate wider charge and discharge conditions without the same degradation anxiety.
Product range
Built for your ride.
We build standard-format packs for e-bikes and scooters, and we can also design custom packs or integrate our cells into your existing architecture.

For e-bikes
Drop-in where riders expect it.
Designed for commuter, cargo, and trekking bikes with compatibility in mind across frame types, mounting standards, service access, and daily charging habits.
For e-scooters
Compact, balanced, city-ready.
Engineered for daily urban range, tighter packaging envelopes, and balanced weight distribution so the vehicle rides better and stays easier to service.
What's inside
Our electrolyte. Our cells. Your advantage.
Our electrolyte
Optimised for stability, usable temperature range, and long service life — without giving away the IP that makes the chemistry worth owning.
Our cell design
Engineered around the form factors and performance envelope required by micromobility, rather than trying to force a generic cell into a better story.
Our BMS and pack engineering
Protection, balancing, state monitoring, and pack integration designed as one system so the chemistry, electronics, and enclosure work together.
Certification pathway
Compliance planning is built into development to support OEM, fleet, and import customers who need credible transport and market-entry readiness.

Who it's for
Made for the people who actually depend on it.
Daily commuters
Riders who want dependable range, simple charging, and peace of mind in apartments, offices, and shared spaces.
Delivery and fleet operators
Operators who cannot afford downtime, cold-weather drop-off, or battery safety incidents across dozens or hundreds of vehicles.
Bike and scooter manufacturers
OEM teams looking for a safer, more sustainable pack that differentiates the product instead of copying the same lithium stack.
Service and retrofit partners
Integrators who need maintainable, swappable, standards-aware packs that fit real field servicing and replacement workflows.
Sustainability story
Better for your ride. Better for the planet.
Sodium-ion gives us a stronger lifecycle story: abundant raw materials, no cobalt dependency, lower-pressure sourcing, and a long service life that can reduce total waste. Combined with a pack designed for maintainability and application-specific integration, the result is a battery with a more credible long-term environmental case.
Lifecycle advantage
No cobalt
Avoids one of the most ethically fraught battery materials.
Lifecycle advantage
No lithium bottleneck
Less exposed to the volatility of scarce-material supply chains.
Lifecycle advantage
Long service life
More useful cycles means fewer replacements and less waste.
Lifecycle advantage
Designed for recyclability
Pack architecture and chemistry choices support end-of-life planning.
Social proof
Trusted by riders and builders.
If you're evaluating an early-stage platform, the proof you need is technical credibility, integration readiness, and a clear validation path — not borrowed logos.

FAQ
Questions buyers ask before they switch.
How does the price compare to lithium-ion?
At low volume, pricing depends on pack format and integration requirements. At scale, sodium-ion benefits from abundant raw materials and a chemistry that is not tied to cobalt or lithium bottlenecks, improving long-term cost stability.
What real-world range can I expect?
On the same vehicle, real-world range is expected to improve by roughly 20–25% compared with an equivalent lithium-ion pack, because our packs are lighter and more compact — the vehicle simply has less mass to move.
How long does it last?
The pack is engineered for thousands of charge cycles, with longevity shaped by usage profile, charging pattern, and thermal environment. For fleet and OEM customers, we map service life against total cost of ownership.
Is it heavier than lithium-ion?
No — our sodium-ion packs are lighter and more compact than comparable lithium-ion packs. Sodium chemistry is inherently safer, so it needs far fewer passive safety components than NMC, which means a smaller, lighter, more space-efficient pack at the system level.
Can it retrofit my existing bike or scooter?
In many cases, yes. We can design custom packs or integrate our cells into existing pack architectures, depending on voltage, mount, controller compatibility, and available space.
What certifications are you targeting?
Certification planning is part of the engineering process from the start, including transport, pack compliance, and market-specific approval pathways required by OEM and import customers.
What warranty and end-of-life support do you offer?
Warranty structure depends on the application, expected cycle profile, and whether the project is direct-to-rider, fleet, or OEM. We also support end-of-life planning through long service life, replaceable pack strategies, and recycling pathways.
