Today, the electric vehicle industry is experiencing flourishing development, and power batteries, as the "heart" of electric vehicles, directly influence the performance of the entire vehicle and even the direction of the entire automotive industry. As a central force in the field of power batteries, power battery suppliers naturally bear the responsibility of advancing the industry. Among the many outstanding power battery suppliers in the industry, VREMT, with its solid technological expertise and relentless spirit of innovation, has succeeded in making major breakthroughs in battery technology, opening up countless possibilities for PHEV solutions and the development of car battery packs.
In recent years, lithium iron phosphate (LFP) batteries have seen their market share surpass that of ternary lithium-ion batteries in 2021, thanks to their inherent advantages in safety and longevity, and this trend continues to intensify. However, ternary lithium-ion batteries are still widely used in high-performance models due to their fast charge and discharge rates and good low-temperature discharge performance. As a power battery supplier, VREMT has successfully reversed this situation by becoming the first to mass-produce ultra-fast charging LFP batteries. Their 800V battery offers charge and discharge performance comparable to ternary lithium-ion batteries, with a charge rate of 4.5C, enabling ultra-fast charging in 15 minutes for an additional range of over 500 km. Even in challenging conditions at -10°C, the charging speed is at least a quarter faster than similar products. Additionally, with a pulse discharge rate of 16C in 3 seconds, it can release a massive amount of energy instantly.
The ability of VREMT's high-voltage battery pack to achieve such exceptional performance relies on two key technologies. In terms of lithium-ion transport, VREMT is the first power battery supplier to develop full lithium-ion acceleration technology. The cathode of the high-voltage battery pack uses nanometer-sized lithium iron phosphate particles and a composite conductive agent, which increases reaction activity and the number of lithium ions participating in energy transport per unit time. An ultra-fast dissociation electrolyte is used between the cathode and anode to reduce the resistance to lithium-ion movement, ensuring their rapid passage. Additionally, a three-layer, multi-porous composite membrane is introduced to increase the porosity rate per unit surface area, ensuring rapid lithium-ion passage. The anode uses a low-enthalpy graphite-based material, a multi-gradient electrode design, and a low surface impedance SEI layer, reducing impedance to lithium-ion insertion and creating an efficient transmission channel and massive storage space. Furthermore, this battery adopts a cell structure with a double riveted terminal design to improve the overcurrent capacity by 100%. During discharge, lithium ions and electrons return via the same path, traveling more distance and faster per unit time, enhancing 800V battery packs the battery's discharge performance.
Moreover, rapid charging at high voltage and high current leads to an exponential increase in heat within the cell. Thus, in addition to the double riveted terminal design, VREMT has introduced a multi-tab stacked design, which improves safety while allowing more uniform heat distribution within the cell, making temperature control more effective and accelerating low-temperature charging.
As a professional power battery supplier, VREMT's high-voltage battery pack not only offers a higher quality option for PHEV solutions but also sets a new benchmark for the development of car battery packs. In the wave of transition to automotive electrification, the performance of power batteries directly influences consumer experience. VREMT's technological advancements have enabled electric vehicles to take a significant step forward in charging convenience and extreme safety.
With the continuous expansion of the electric vehicle market, the demand for power batteries will continue to grow. In the future, VREMT will continue to increase its research and development investments, constantly innovate in technology, and provide more high-quality high-voltage battery pack products for the development of PHEV solutions and car battery packs. This will accelerate the advent of the era of high-power fast charging and propel the electric vehicle industry to new heights.
