This sodium ion battery portable power station adopts a single 230Ah sodium-ion cell design, featuring exceptional low-temperature performance with 85%–92% capacity retention at -20°C and stable discharge at -30°C, removing the need for internal heating films to cut costs. It boasts superior safety over lithium iron phosphate batteries with strong resistance to puncture, extrusion and impact, no lithium dendrite risks, and excellent tolerance to overcharge and over discharge. Abundant sodium resources insulate it from lithium price volatility for favorable long-term kWh costs. The single-cell structure eliminates series voltage imbalance, simplifying BMS circuitry, lowering failure rates and easing production and after-sales service. With centralized, uniform heat dissipation, the product delivers markedly lower overheating risks compared to multi-cell battery packs
