In consumer electronics, composite current collectors enable batteries with higher energy density, reduced weight, and enhanced safety. This meets the demand for slim, lightweight designs while extending battery lifespan.

Composite current collectors are used in power batteries for new energy vehicles. Their "metal-polymer-metal" sandwich structure enables an increase in energy density by 5-10% and a reduction in weight by up to 60%, while significantly enhancing safety performance in tests such as nail penetration. This technology also supports fast charging and extends cycle life, driving breakthroughs in vehicle range and safety.

By integrating composite current collectors into energy storage batteries, system performance is significantly enhanced. This technology boosts energy density and cycle life while improving safety, contributing to the efficient and stable operation of photovoltaic energy storage systems.

Composite current collectors have become a critical component for spacecraft batteries due to their lightweight nature and high safety. By replacing traditional metal foils, they significantly reduce the weight of space power systems and increase payload capacity.

Featuring a polymer-metal sandwich structure, the composite current collector can be precision-engineered to a mere 6-8μm, over 50% thinner than traditional 12μm copper foil. This ultra-thin profile and over 50% lower density make it an ideal replacement for copper foil in circuit substrates, paving the way for radical weight reduction in space-constrained applications like foldable smartphones and wearable medical devices (e.g., EEG headbands).
