Current Collector Innovations for Lithium-Ion Battery Performance
Summary
Current collectors play a pivotal role in the design and function of lithium-ion batteries by providing a low-resistance pathway for electron transport between active materials and the external circuit. Recent advances have sought to reduce weight and thickness, enhance mechanical resilience, improve interfacial adhesion and safety, and enable compatibility with emerging electrode chemistries. Innovations span the development of metallised polymer films that supplant traditional copper and aluminium foils, three-dimensional porous and textile-based architectures to boost active surface area, and tailored surface treatments to fortify electrode–collector interfaces. Such developments promise higher energy and power densities, faster charge rates and enhanced cycle life, while also addressing scalability through roll-to-roll processes and novel contacting methods. As the field moves towards all-solid-state batteries and ultra-fast charging applications, current collector design has become a critical lever for optimising both performance and manufacturability on a global scale.
