A wide range of consumer/professional electric/electronic devices desperately need batteries with increased energy density. Li-ion batteries (LIB) are the most widely used and the best platform candidate.
Key criteria are cycle life and power charge/discharge capacity.
And there is a consensus that nanostructured silicon is a new and very promising anode material to deliver an energy density breakthrough. In particular, it is expected that silicon nanowires can double the LIB energy density. Still, a lot of technological challenges are to be overcome before nanostructured silicon is adopted by the LIB manufacturers.
Currently, silicon-based anode technologies are limited to electronics applications.The main challenges to the adoption of nanostructured silicon
The main challenges to the adoption of nanostructured silicon are: insufficient performances, its poor manufacturability and its high production cost.
enwires offers an innovative method of silicon nanowire mass manufacturing that solves these challenges by using harmless and stable reagents, low-cost simple reactors, and energy-efficient technological processes.
Silicon nanowire mass manufacturing
Increasing energy density and circle life of batteries used for many mobiles as well as electronic applications is one of the core activities of EIT RawMaterials. The activities aim at reduced content of critical or toxic raw materials as well as improved production efficiency and recyclability. Several projects are working on the market introduction of innovative battery materials as well as on improved production lines, mainly for automotive applications. enwires’ technology is thus a promising addition to EIT RawMaterials partners activities. EIT RawMaterials is supporting enwires by initiating collaborations with the community, design of production reactors and the nanosilicon products.
