2026 is widely regarded as the first year of large-scale commercialization of sodium batteries in the industry. After shipments reached 9GWh in 2025, the sodium electricity industry is experiencing a key leap from demonstration projects to large-scale delivery.

The integrated production line of Zhongke sodium 2GWh sodium and electricity has been settled in Wuhan, which is the world's first large-scale production line focusing on standardized mass production of sodium battery pack, aiming to solve the problem of sodium and electricity BMS matching, layered thermal management, engineering pain points such as balanced control of large-capacity clusters mark that sodium power has officially completed the closed-loop production capacity of the full chain of material-cell-system integration, completely bid farewell to the demonstration project stage, and entered the GWh-level commercial delivery cycle.

The advantages of sodium battery are clear. Compared with lithium batteries, sodium batteries have good characteristics of wide temperature and low temperature, and the low temperature performance can cover-40℃ to 80℃. Changde Kunyu's polyanion system sodium ion battery has achieved stable operation at minus 40℃ to 60℃, low temperature-40℃ discharge capacity retention rate greater than or equal to 90%, normal temperature cycle life greater than or equal to 12000 times. These performance indicators mean that sodium batteries have real potential for replacement in scenarios such as energy storage, two-wheeler, low-and medium-endurance new energy vehicles, and UPS.

but PACK factory to say, the sodium battery brings more than a new cell. The BMS strategy, thermal management scheme and structural design of sodium electricity are different from lithium electricity. The voltage platform of sodium battery is between 2.8 and 3.7V, which is different from that of lithium battery 3.0 to 3.7V; The positive and negative electrode materials are switched from ternary and lithium iron phosphate to polyanion type and layered oxide type, the fluid collection is switched from copper foil to aluminum foil. These changes require the PACK factory to re-match at the system level.

Dongguan Juneng New Energy Technology Co., Ltd. has accumulated more than 10 years of experience in battery pack structure design, heat management and BMS development, covering energy storage, industrial equipment, AGV cargo van and other fields. Facing the technical route switching brought by sodium battery, the flexible manufacturing system of energy-gathering new energy and the BMS design idea of "one scenario and one strategy, this enables it to quickly adapt to the system level when the cell system changes. For equipment manufacturers that are evaluating sodium-electricity solutions, it is much safer to choose a partner with cross-chemical system PACK design capabilities than to wait until cell is in place to find a solution.
