A high capacity silicon–graphite composite as anode for lithium-ion batteries using low content amorphous silicon and compatible binders
Silicon has gained significant attention as a lithium-ion battery anode material due to its high theoretical capacity compared to conventional graphite. Unfortunately, silicon anodes suffer from poor cycling performance caused by their extreme volume change during lithiation and de-lithiation. Compo …
Here, the use of a laser-induced silicon oxide (LI-SiO x) layer derived from a commercial adhesive tape to improve the reversibility of Li metal batteries (LMBs) is studied. The silicone-based adhesive of the tape is converted by a commercial infrared laser into a homogeneous porous SiO x layer deposited directly over the current collector.

The laser-etched Si-doped polyimide (L-Si-PI) anode achieves 1332 mAh g −1 capacity in the first discharge and a high capacity of 1057 mAh g −1 after 1500 cycles at 0.2 A g −1 for half lithium-ion batteries (LIBs).
Pfleging et al. 5 showed that laser patterned channels in NMC cathodes with a thickness of 55 μm improved wetting with the liquid electrolyte due to the capillary effect and increased the specific discharge capacity and lifetime compared to the reference electrode without laser patterning. The shorter wetting time results in a reduction in …

New electrode architectures promise huge potential for improving batteries'' electrochemical properties, such as power density, energy density, and lifetime. In this work, the use of laser-induced forward transfer (LIFT) was employed and evaluated as a tool for the development of advanced electrode architectures. For this purpose, it was first …
As potential alternatives to graphite, silicon (Si) and silicon oxides (SiOx) received a lot of attention as anode materials for lithium-ion batteries owing to their relatively low working potentials, high theoretical specific capacities, and abundant resources. However, the commercialization of Si-based anodes is greatly hindered by their massive volume …
Si has been considered as one of the most attractive anode materials for Li-ion batteries (LIBs) because of its high gravimetric and volumetric capacity. Importantly, it is also abundant, cheap, and environmentally benign. In this review, we summarized the recent progress in developments of Si anode materials. First, the electrochemical …
