PLB Breaks New Ground in Low-Temperature Technology: Unfazed at -40℃
In the surging wave of the global new-energy industry, continuous innovation in lithium-ion technology is the engine that keeps the sector moving forward. As a leading manufacturer of 26650 lithium cells, Power Long Battery (PLB) has never stopped pushing the envelope. Its latest milestone: an advanced low-temperature LiFePO₄ cell capable of stable discharge at -40℃ and safe charging at -20℃, with a peak discharge rate of up to 80C. The achievement cements PLB’s position at the forefront of extreme-cold battery performance and opens exciting avenues for real-world deployment.
Relentless R&D to Shatter the Low-Temperature Barrier
Lithium-ion batteries traditionally suffer sharp performance losses below 0℃, where capacity, discharge capability and safety all drop dramatically. That limitation has restricted their use in frigid regions and harsh operating conditions. PLB set out to change that. By re-engineering key materials, cell architecture and electrolyte chemistry—and then validating each iteration through exhaustive testing—the team has delivered a genuine breakthrough in low-temperature capability.
Dependable Discharge at -40℃
The new LiFePO₄ cell remains fully functional in -40℃ environments—a best-in-class figure that stretches the operational boundary of phosphate chemistry. From northeastern winter outposts to polar-research stations, equipment powered by PLB cells can now run smoothly and efficiently despite extreme cold.
Safe, Efficient Charging at -20℃
Charging below freezing typically risks lithium plating and severe safety hazards. PLB’s proprietary electrolyte and anode blend suppress side reactions, enabling the cell to charge safely and effectively even at -20℃. Users gain true all-temperature usability without compromising longevity or safety.
Up to 80C Discharge for Instant Power
Beyond cold-weather prowess, the next-gen cell also excels in rate performance. A maximum continuous discharge rate of 80C means it can deliver very high current on demand—ideal for specialty gear, polar exploration tools and any high-power device working in sub-zero climates.
Deep Material & Process Innovation
Cathode: Optimised LiFePO₄ crystal structure and conductive network accelerate electron flow and ion diffusion.
Anode: Advanced graphite composite paired with a tailor-made electrolyte sustains lithium intercalation in the cold.
Electrodes: Precision coating and calendering raise density and uniformity for lower internal resistance.
Cell Design: Multi-tab (soon full-tab) layout enhances thermal management and further cuts impedance, ensuring stable output in harsh conditions.
Powering Diverse Applications
PLB’s low-temperature cells remove a key barrier for starter batteries, outdoor UPS, emergency power supplies, military hardware, and other equipment that must perform reliably in severe cold. As climate variability intensifies, these cells will supply robust, safe energy for mission-critical systems worldwide.
Committed to Quality, Poised for the Future
Guided by the principle of “serving customers and creating value,” PLB will continue to invest heavily in R&D, expand its low-temperature product family, and help partners upgrade to cleaner, safer and more efficient energy solutions. Together with our customers, we look forward to building a greener high-performance future.
