Environmentally Friendly Sodium-ion Batteries
Sodium-ion batteries utilize eco-friendly components that are abundant in nature. Upon disposal, they can be safely integrated into household waste, naturally decomposing without harming land or water sources. Compliant with various international environmental certifications, sodium-ion batteries alleviate the need for ecological surcharges.
Higher Depth of Discharge, Over 90% DOD
With a remarkable depth of discharge (DOD) exceeding 90%, Keheng sodium-ion batteries offer superior usability. Unlike lead-acid batteries with a DOD of 45%, our batteries provide more accessible power in systems of equivalent capacity. Experience extended lifespan and worry-free operation, surpassing 15 years of reliable service.
Enhanced Safety and Versatility
Keheng sodium-ion batteries are engineered to operate flawlessly within a temperature range of -30℃ to 60℃, ensuring optimal performance in various environments. Free from bulging, spontaneous combustion, or explosions, our batteries adapt seamlessly to temperature fluctuations, guaranteeing safety in outdoor energy storage setups, household appliances, automotive power systems, and industrial applications.
