Breakthrough Bilayer Electrode Technology from Queen Mary University of London Solves Fast-Charging Battery Lifespan Challenge

Recently, Queen Mary University of London published a landmark battery research achievement in the top-tier journal *Nature Communications*. Through innovative in-situ imaging and design methods, the team successfully developed a gradient-structured bilayer composite electrode, providing a novel solution to the long-standing "fast-charging vs. lifespan" dilemma in the industry.

Technological Breakthrough: Intelligent Gradient Design Reshapes Electrode Structure

During rapid charging and discharging of traditional homogeneous electrodes, mechanical stress generated by uneven lithium-ion intercalation and deintercalation easily leads to electrode material fracture and failure. The research team at Queen Mary University of London adopted an entirely new approach:

• Precise Observation**: Utilizing advanced in-situ imaging technology to reveal the micro-deformation mechanisms of electrode materials in real-time for the first time
• Intelligent Design**: Constructing a gradient bilayer structure composed of a high mechanical strength layer and a high ionic conductivity layer
• Stress Management**: Effectively guiding lithium-ion flow, dispersing internal stress, and protecting electrode integrity

Exceptional Performance: Redefining Fast-Charging Battery Standards

Experimental data confirm that this bilayer electrode demonstrates unprecedented comprehensive performance:
• Extended Lifespan**: After 1000 cycles at a high 5C rate, capacity retention remains above 80%
• Ultra-Fast Charging**: Unique ion transport channel design significantly enhances fast-charging capability
• Cost Optimization**: By improving material utilization and reducing precious metal usage, manufacturing costs are expected to decrease by 20-30%

Industry Impact: Leading the Development of Next-Generation Battery Technology

This breakthrough not only provides a specific electrode design solution but, more importantly, establishes a new paradigm of "understand first, design later" in materials research. As an important participant in the battery technology field, we are closely monitoring the industrialization progress of this technology and look forward to translating such innovative achievements into practical products, jointly promoting the sustainable development of the electric vehicle industry.
