High Area Capacity Lithium-Sulfur Full-cell Battery with Prelitiathed Silicon Nanowire-Carbon Anodes for Long Cycling Stability

by:CTECHi     2019-12-16
We present a complete Li/S battery that solves high power electricity using balanced and high capacity electrodes
Mobile app.
The anode consists of a component that is densely grown on a 3D Carbon grid by silicon nanoparticles as active materials, as light
The weight current collector provides extremely high area capacity for Reversible Li storage up to 9 mah/cm 2.
The dense growth is guaranteed by developing a multi-functional Au precursor for uniform deposition of the Au layer on a 3D substrate.
Compared to the metal Li, the system exhibits excellent performance as an anode for the Li/S battery, such as safe operation, long cycle life and easy handling.
These electrodes are combined with S/C composite cathode with high area density to form Li/S full
