3D battery

Pfleging, Wilhelm



Abstract (englisch): Laser surface texturing of battery materials (electrode, current collector, separator) is developed in order to generate advanced 3D electrode architectures with increased active surface area leading to an improved lithium-ion diffusion kinetics during electrochemical cycling. High-rate capability and an improved cycle stability is achieved. Besides the successful transfer of 3D battery concept to thick film electrodes, a tremendous improvement of electrode wetting with liquid electrolyte could be obtained. This technology can be applied in order to increase cell reliability during the battery production process, to shorten production times of lithium-ion cells as well as to increase battery life-time.
