DEFORD releases their sodium-ion truck battery POC program

As a pioneer in the application of sodium-ion batteries, DEFORD New Power Co., Ltd. officially released its first-generation sodium-ion truck battery proof-of-concept program on September 3, 2025. According to this POC program, DEFORD will invite some customers to conduct POC tests on their innovative sodium-ion truck batteries starting in December, 2025, and will ensure that the invited customers receive the test batteries before November 30, 2025. The POC program will last for 9 months and the official report will be completed by the end of Q3 of 2026. 

Lead acid battery has been dominated the truck start battery market for more than one century. Lithium-ion battery is not good at cold-starting the engine and therefore cannot meet the requirements of starting batteries. Sodium-ion battery has excellent low-temperature discharge performance and can still meet the 10C discharge requirements even at -28 degrees Celsius. In terms of CCA performance, sodium-ion battery is even more advantageous than lead acid battery. 

The sodium-ion truck battery is a dual-purpose battery with excellent performance. It can be used as a starting battery or a deep cycle battery. Its excellent temperature adaptability and up to 2,000 cycle life make it have significant performance and cost advantages over traditional lead-acid truck batteries. 

DEFORD has conducted a lot of tests on sodium-ion batteries since 2023 and has been looking for the best application scenario for sodium-ion batteries. We successfully launched a POC program for sodium-ion start-stop batteries in Q3 2025, and a lot of potential customers have contacted us and actively participated in our POC program. The operating environment of sodium-ion truck batteries is more stringent than that of sodium-ion start-stop batteries, and the frequency of use is also much higher than that of sodium-ion start-stop batteries. "We have accumulated a large amount of test data through long-term internal testing. Through this test data, we have a deep understanding of how to design our sodium-ion truck battery systems, especially how to design a dedicated intelligent BMS for them. We need to ensure that our sodium-ion truck batteries can be foolproof in complex working conditions." Steven Leung, General Manager of DEFORD New Power Co., Ltd. introduced. 

Through this POC program, our potential customers can fully understand the advantages of sodium-ion truck batteries and lay a solid foundation for the market launch of this product in 2026. "If the POC program goes well, we will work tightly with our customers to launch our sodium-ion truck batteries in Q4, 2026." Steven Leung, General Manager of DEFORD New Power Co., Ltd. commented.
