Why  will we choose the sodium ion battery ?

🌡️Excellent low-temperature performance – Maintains high discharge efficiency even at -20°C or lower, ensuring reliable starting.

🌡️High safety – Better thermal stability than lithium batteries, low risk of thermal runaway, overcharging, or short circuits.

🌡️Fast charging capability – Supports high-rate charge/discharge, responds quickly to frequent start-stop cycles.

🌡️Cost advantage – Abundant and widely distributed sodium resources, much lower material cost than lithium, suitable for large-scale use.

🌡️Environmentally friendly – Contains no scarce metals like cobalt or lithium, reducing environmental impact in mining and disposal.

🌡️Long cycle life – Provides higher cycle numbers under start-stop conditions compared to traditional lead-acid batteries.
