SiNANOde® is a high-performance silicon-graphite nanomaterial capable of significantly increasing the energy density and cycle life of a large variety of Lithium-ion batteries.

SiNANOde® consists of silicon nanowires grown on various types of commercially available graphite powder. SiNANOde® can be produced in various grades ranging from 4% to 32% silicon to carbon weight ratio.

The performance of full cells using SiNANOde® can be optimized to meet the specific requirements of each application.

The SiNANOde® anodes can be matched with many existing and new cathodes, including NCA (Nickel Cobalt Aluminum Oxide), LCO (Lithium Cobalt Oxide), NCM (Nickel Cobalt Manganese Oxide) cathodes and other materials.

SiNANOde® is well suited for many market segments ranging from Military, Power Tools and Medical applications, to higher volume applications in Consumer Electronics and Electrical Vehicles.

When traditional Lithium-ion batteries are charged, energy is stored in the anode electroactive material, which is mostly made of graphite. An often quoted "rule of thumb" is that about 1 kg of graphite is needed per kWh of battery capacity. For example, approximately 80 kg of graphite are needed for an 80 kWh EV battery or approximately 30 grams of graphite are needed for a 30 Wh tablet battery (1 kWh = 1000 Wh and 1 kg = 1000 gram).

The SiNANOde® materials combine graphite and silicon nanowires to provide greater energy stored per kg of anode electroactive material.  This greater energy density depends on the weight ratio of silicon nanowires to graphite: for example 10% Si/C SiNANOde® can store an amount of energy per kg which is twice greater than the energy per kg stored in graphite while 20% Si/C SiNANOde® can store an amount of energy per kg which is three times greater than the energy per kg stored in graphite (0.5 kg of SiNANOde material with 10% Si/C ratio is sufficient for about 1 kWh of battery capacity).

Thus, an annual manufacturing capacity of 100 tons (= 100,000 Kg) of 10% Si/C SiNANOde® is sufficient for about 200,000 kWh = 200 MWh of lithium battery capacity.
