BatteroTech unveils its Mercury super-charging technology. This innovation addresses two of the most pressing concerns for EV owners: range anxiety and lengthy charging times. With the ability to add 400 kilometres of range in a mere 10-minute charge, BatteroTech’s Mercury batteries are set to enhance the EV driving experience.
The Mercury super-charging system, an evolution of BatteroTech’s “Twin-star” battery portfolio introduced in 2022, represents a leap forward in battery technology. While the previous generation offered 3C fast-charging in 15 minutes, the new Mercury batteries boast a 4C super-charging capability, reducing charging time to 10 minutes. This advancement effectively allows EV owners to recharge their vehicles in roughly the same time it takes to enjoy a coffee break, making long-distance travel more convenient and accessible.
At the heart of this innovation are three key technical structures developed by BatteroTech: Speedy Lithium-ion Transfer, Lightning-speed Pathway, and Rock Framework. These technologies work in concert to overcome the limitations of traditional battery cells, which often struggle with lithium-ion insertion and leaching during fast charging.
The Mercury polycrystalline framework and graphite coating on the anode, enhanced with fast ion conductors, create smoother and swifter pathways for lithium-ion intercalation. This design, coupled with isomeric pole pieces and flooded battery clusters, optimises lithium ion concentration and migration throughout the anode structure.
On the cathode side, BatteroTech employs core-shell and graded particles, implementing a lean design at the nanoparticle level. This approach reduces the energy barrier for lithium-ion deintercalation, particularly beneficial in low-temperature environments where battery performance typically suffers.
The electrolyte formulation has also been refined, featuring high-throughput film formation and full-domain low viscosity. These properties significantly reduce resistance to lithium-ion movement between cathode and anode, enabling efficient charging across a wide range of temperatures.
To manage the heat generated during rapid charging, BatteroTech has developed the Mercury Lightning-speed Pathway. This system incorporates a cross-linked grid, cathode carbon coating nanotechnology, low-resistance coating, and two-directional conductive foil. By optimising the structural design and current collectors, BatteroTech has managed to streamline 20% of spare parts and reduce physical transmission paths, resulting in lower impedance and heat generation.
Safety remains a top priority, addressed by the Rock Framework design. This includes a high-safety coating separator, a high-resistance insulation layer, and high-impedance protective films on welding imprints. These features work together to prevent internal short circuits and enhance overall battery reliability.
BatteroTech’s innovation extends beyond the cell level to the entire battery system. The company has introduced a cost-effective cooling system that maintains cell temperatures below 45°C during charging under normal conditions, preserving battery life while rivalling the efficiency of large-surface cell cooling technologies. This approach not only increases the volume integration efficiency of the battery system by 5% but also reduces thermal management and system part costs by the same margin.
BatteroTech’s Mercury technology shows good performance even in extreme conditions. The system can charge a vehicle to 80% state of charge (SOC) in just 10 minutes at temperatures as low as -20°C, a feat that sets new standards for the industry.
As a subsidiary of Tsingshan Industry, BatteroTech benefits from stable access to lithium resources, providing a significant advantage in raw material sourcing and cost management. The company is poised for rapid expansion, with plans to complete its Phase-III 45GWh production line in 2024, bringing its total production capacity to 79GWh. Mass production of the Mercury 4C fast-charging batteries is slated to begin by the end of 2024.
