Silicon production...at the Leading Edge

OUR STORY

In 2018, global governments prohibited End-of-Life (EoL) PV panel disposal in landfills, triggering a search for recycling solutions. However, handling silicon proved challenging for many machinery producers. Government incentives and EU programs prompted the rise of WEEE photovoltaic recycling companies globally. Despite this, the sale of purified silicon faces hurdles due to inefficient methods. Currently, most recovered silicon is down-cycled, used in applications like concrete. SiPow addresses this by aiming to be the missing link in the pure silicon market, offering an energy-efficient purification process with a high Return on Investment (RoI) for monocrystalline silicon.

Resource Revolution, No Mine Required.

SiPow envisions global expansion as a Resource Revolution with No Mine Required. Two alternatives to SiPow and NanoPow's crystalline Silicon nano-powder are graphite and amorphous Silicon powder. In current Li-ion batteries, the anode electrode, mainly graphite, includes micron-sized Silicon powder or amorphous nano-sized SiO to boost energy density. However, using micron-sized Silicon powder reduces cycle life, and amorphous Silicon nano-powder has lower specific charge capacity than crystalline Silicon nano-powder. Introducing nanometer-sized crystalline Silicon into the anode electrode proves superior, enhancing both specific capacity and lifetime (10 times higher absorption capacity than graphite)

Innovation at the leading edge

Most nanosilicon powder producers, mainly in China or the USA, predominantly produce amorphous Silicon nano-powder, with exceptions. However, their material often has lower density and capacity due to reliance on cost-intensive hydrochloric acid in production. This requires post-use dilution and neutralization. None use purified end-of-life solar cells as feedstock, unlike SiPow's circular economy approach. SiPow aims to maximize resource retention by reducing raw material usage, waste, emissions, and energy consumption. Notably, SiPow's energy-efficient monocrystalline silicon production starts from partially purified silicon (70%-90%) using novel thermo-chemical approaches to minimize additional energy costs. In contrast, conventional methods use high-energy electric furnaces, making adaptation with recovered silicon challenging.
