Sodium-ion batteries exhibit high thermal stability and more robust electrochemical characteristics, effectively mitigating risks of thermal runaway and offering significantly improved operational safety.
Capable of approximately 1,000 charge-discharge cycles, these batteries reduce the need for frequent replacements, providing a reliable long-term solution for energy storage and motive applications.
Even if the battery remains at 0V for a month due to over-discharge, its capacity can be almost fully recovered to 100%, significantly reducing the risk of permanent failure.
Designed to operate reliably in extreme temperatures from -30°C to 70°C, they maintain approximately 80% charge-discharge efficiency even at -30°C.
With a shelf life of about 5 years and low self-discharge rate, these batteries are ideal for backup power and intermittent use, minimizing maintenance efforts.
Excellent energy retention and discharge performance under cold conditions ensure consistent device operation in frigid climates without significant power loss.
As the supply chain matures, sodium-ion batteries are expected to be around 30% more cost-effective than LiFePO₄ batteries, offering compelling economic benefits.
