[LBM TECH]T246 low-temperature high rate positive electrode material injects new kinetic energy into the performance breakthrough of new energy heavy-duty trucks

Driven by the strong goal of "dual carbon", the new energy industry has ushered in unprecedented development opportunities, and as the core force of green transformation in the logistics and transportation field, the development direction and importance of new energy heavy-duty trucks have become increasingly prominent. In recent years, the new energy heavy-duty truck market has shown an explosive growth trend. As a major emitter of carbon in the field of road transportation, heavy-duty trucks account for only 3% of the total number of cars, but contribute 43% of the carbon emissions from road transportation. Therefore, vigorously promoting new energy heavy-duty trucks is a key measure to reduce carbon emissions in the logistics industry and improve urban air quality, and is also an important link in promoting the green and low-carbon transformation of the transportation industry. ​

With the continuous advancement of technology, key indicators such as endurance and cost-effectiveness of new energy heavy-duty trucks are constantly being optimized, gradually expanding from short distance and regional markets to mid way and mainline logistics. This expansion trend has put forward higher requirements for the battery performance of new energy heavy-duty trucks, especially their ability to operate in low-temperature environments and their rate performance at high horsepower output, which have become important factors restricting their further development. ​

T246 Emerges: Technological Breakthrough in Balance Performance
In this context, LBM, with its profound technological accumulation and keen market insight, officially released a new positive electrode material called T246 in May this year, targeting low temperature and high rate requirements. This product can be regarded as a breakthrough achievement in the industry. It not only perfectly retains the technical advantages of Iron Lithium No.1 product in low-temperature performance, but also achieves a qualitative leap in rate performance. T246 material exhibits excellent balance characteristics in optimizing battery performance. At a low temperature of -20 ℃, the capacity retention rate of this material can reach over 60%, and it has a relatively stable capacity retention ability, effectively solving the industry pain point of significant battery performance degradation in low temperature environments. This is of great significance for new energy heavy-duty trucks that need to operate normally in cold regions or winter. At the same time, in the conventional operating temperature range, its high powder compaction (greater than 2.40g/cm ³) and optimized particle size distribution provide a relatively balanced energy density performance for the battery, enabling the battery system equipped with this material to achieve a balance between low temperature and endurance performance, meeting the continuously improving endurance requirements of new energy heavy-duty trucks.

Technological innovation: unlocking high magnification and fast charging capabilities
Through advanced processes such as precursor nanomaterialization and bulk doping, T246 achieves a more uniform lithium-ion crystal structure, shorter transmission path, faster migration rate, and better conductivity, thereby achieving excellent rapid instantaneous charge and discharge performance. Its 1C charge and discharge capacity reached over 160mAh/g and 145mAh/g respectively, an increase of 7.6% compared to the original product. ​
This high magnification performance is particularly suitable for new energy heavy-duty trucks that require high horsepower output. In practical applications, new energy heavy-duty trucks require strong power support when starting, accelerating, and carrying heavy objects to climb slopes. T246 material can ensure that the battery instantly releases powerful energy, meeting the vehicle's high horsepower output requirements, significantly improving the vehicle's power performance and operational efficiency, and perfectly meeting the higher power requirements of new energy heavy-duty trucks in the process of expanding to mid way and mainline logistics. ​

Strength Witness: LBM's Forward looking Layout
At present, the T246 product has entered the mass production preparation stage, which fully demonstrates LBM's strong strength in the research and industrialization of positive electrode materials. In the future, LBM will continue to uphold the spirit of innovation, take T246 products as a new starting point, provide better material solutions for the development of new energy heavy-duty trucks, help new energy heavy-duty trucks play a greater role in green logistics transformation, and promote the transportation industry to move towards a cleaner and low-carbon future.
