In the context of the flourishing development of the electric vehicle industry, power batteries, as essential components, directly determine the competitiveness of vehicles. VREMT, as a leader among power battery suppliers, has not only broken the performance ceiling of lithium iron phosphate (LFP) batteries with its innovative 800V battery technology but also established a new standard for the development of automotive battery packs and high-voltage battery packs, while demonstrating remarkable excellence in optimizing PHEV solutions.
Although lithium iron phosphate batteries hold a significant position in the market due to their safety and long lifespan, their slow charge and discharge rates and poor performance at low temperatures make them difficult to compete with ternary lithium batteries in the high-performance vehicle sector. However, the 800V battery launched by VREMT, a power battery supplier, has changed this situation. It is the world's first mass-produced ultra-fast charging LFP battery, with a charging rate reaching 4.5C, allowing for extreme charging in 15 minutes to increase the range by over 500 km. Its fast charging capability in all environmental conditions is remarkable, with a charging speed at -10°C at least a quarter faster than similar products. In terms of discharge performance, the VREMT 800V battery achieves a pulse discharge rate of 16C in 3 seconds, instantly releasing powerful kinetic energy, helping the Zeekr 007 become the fastest mid-sized sedan in the world, with acceleration from 0 to 100 km/h in less than 3 seconds, and strong acceleration performance in the middle and end stages, without power reduction even at low charge (SOC>20%).
The revolutionary charging principle of the VREMT 800V battery relies on the movement of lithium ions from the cathode material to the electrolyte, crossing the membrane to the graphite anode, while electrons maintain chemical balance by flowing from the cathode to the anode via the external circuit. The cathode material uses nanometer-sized lithium iron phosphate particles combined with a conductive agent, increasing reaction activity to involve more lithium ions in energy transport, significantly improving the energy transmission efficiency of the high-voltage battery pack. The rapid dissociation technology of the electrolyte reduces the resistance to lithium ion movement, allowing them to circulate quickly. A three-layer composite membrane with high porosity ensures the rapid passage of lithium ions. The anode uses a graphite material with low enthalpy change, a multi-gradient electrode design, and a SEI membrane with low surface resistance, reducing the impedance of lithium ion insertion into the anode, creating efficient transmission channels and massive storage space, shortening the lithium ion transfer path.
Simultaneously, to achieve chemical balance, electrons must move rapidly in synchronization with lithium ions. The cell structure with a dual guide pillar design improves the overcurrent capacity by 100%, like switching from a single lane to a double lane, allowing electrons to flow faster and in greater numbers, forming a perfect loop. During discharge, lithium ions and electrons return via the same path, moving faster and in greater numbers per unit time, significantly enhancing discharge performance.
In PHEV solutions, the VREMT 800V battery also stands out. Its high-voltage battery pack combines energy density and charge/discharge efficiency, meeting the long-range needs of plug-in hybrid vehicles while enabling fast charging, enhancing the user experience. Facing the issue of cell overheating caused by high-voltage and high-current fast charging, VREMT introduced a multi-tab design in the dual guide pillar design, improving safety while ensuring uniform heat distribution within the cell, more efficient thermal management, and faster low-temperature charging speed.
Although material characteristics present physical limitations, technological innovation is endless. As a leading power battery supplier, power battery suppliers VREMT, through its 800V battery technology, offers new opportunities for the development of automotive battery packs and high-voltage battery packs. In the future, VREMT will continue to focus on technological research and development, overcoming material barriers, optimizing battery performance, while deepening industrial collaboration, working with all parties to advance the electric vehicle industry towards a new era of greater efficiency and safety.
