Density Modulated Silicon Anode for Lithium Ion Batteries

ended

The overall lithium ion battery market is expected to grow from $37.4B in 2018 to $100.4B by 2025, at a CAGR of 17.1%. The growth of this market is being fuelled by increasing demand for smart devices and other industrial goods. One of the major cost centers for lithium-ion batteries is anode material and it accounts for ~18% of the battery cell. The state-of-the-art anodes suffer from one or more of these problems: • Limited Li storage capacity, • Large irreversible capacity loss, • Low charge/discharge rate capability, • Poor capacity retention upon the charge/discharge cycling. Silicon(Si) is the best material in nature to create LIB anodes of highest energy density with a theoretical limit of 4200 mAh/g charge capacity. However, Si faces asubstantial challenge: Swelling due to extensive volumetric expansion during charging, which leads to breaking of the Si anode and short battery lifetimes. Usage of graphene (hugely recognized as a “wonder material”) can improve such battery attributes to a certain extent with a charge capacity of ~740 mAh/g; however, it adds to battery fabrication costs due its extremely high price. In addition, fabrication costs of the Li-ion batteries with current technologies is reaching to $300/kWh, while EC is targeting 75 €/kWh and U.S. is targeting $80/kWh by 2030. Therefore, there is an urgent need for high energy density and low cost batteries that will enable our electric future in this market. As IFGROUP, we are offering the “DEMAND” technology that allows us to modulate the dennsity of the silicon anode making it flexible and durable. The prominent advantages of DEMAND silicon anodes will be: • Provides high energy density with improved battery life (~10X); • The overall cost of the battery reduces (below $100/kWh); • Can be easily transferred to commercial battery manufacturing (scalable). DEMAND will allow us to generate €156.4M accumulated profit, 143 employees and 1.44 ROI by 2025 and €186.5M EBITDA within the same period
