Why Choose 46145 Sodium Battery? Sodium VS. Lithium 

Good Safety Performance

Sodium batteries do not leak, catch fire, or explode in rigorous tests including overcharging, over-discharging, short-circuiting, puncturing, squeezing, heavy impact, and dropping. Their safety performance is even higher than that of lithium batteries.


Sodium resources are not only more abundant in the Earth’s crust than those of lithium but are also evenly distributed. This benefits the continuous reduction of raw material costs and ensures a long-term stable supply in future development.

Long Cycle Life

The cycle life of the 46145 sodium battery reaches 2000 cycles, which is several times that of lead-acid batteries, and it can achieve a lifespan comparable to lithium iron phosphate batteries within 2 years.

Good Low-temperature Performance

The operating temperature range of 46145 is from -40°C to 60°C, with a wider safety margin. It can still maintain 85% of its performance for continuous discharge at -20°C, making it a blessing for people in cold regions.

High Rate Performance

Sodium batteries have a higher rate performance than lithium batteries, with discharge rates that can even reach 20C. They can be charged to 90% of their capacity in just 15 minutes, significantly reducing your waiting time.

Allows Over-Discharge

Unlike lithium batteries, sodium-ion batteries allow over-discharge because it does not affect their lifespan and safety.

Clean Energy

Sodium batteries are a new type of environmentally friendly energy source. They produce almost no harmful waste during their production, use, and recycling processes.

Application Of 46145 Sodium Battery

Considering the above characteristics, sodium-ion batteries have the potential to replace lead-acid and lithium batteries for large-scale applications in two-wheeled vehicles, passenger cars, and other low-speed electric vehicles, as well as in the industrial and commercial energy storage sectors.
