Lithium Phosphate Batteries
Lithium Iron Phosphate batteries (LFP) are a sub-type of Lithium-ion batteries
that have many advantages over other Lithium battery chemistries like improved
safety, longer life span (3000 cycles at 80% DOD), Fast Charging, wider
operating temperature, High Energy Density, Eco-friendly, High Stability, Low
Maintenance, Low self-discharge rate, etc.
Dawson Nano FePO4 & Fe3(PO4)2 Cathode Materials are best-of-class
materials suitable for Lithium Phosphate & Sodium-Ion Batteries.

Lithium NMC batteries are a combination of Nickel, Manganese, and Cobalt in
different proportions with Lithium. Lithium NMC batteries are marked by specific
energy or power with high energy density compared with other Lithium batteries.
But NMC batteries have safety issues & high costs.

About Dawson Nano
Silicon Anode Material
+
Silicon is the most desirable Anode material for Lithium-ion batteries due to its high energy density (4200mah/g against 372 mah/g of Graphite Anode) and low price. But it needs to be perfectly engineered for long-lasting, fast charging and protection from volume expansion (around 300%). To meet the above
challenges, we have perfectly developed the Dawson Silicon Nano powder.
+
Lithium Iron Phosphate batteries (LFP) are a sub-type of Lithium-ion batteries that have many advantages over other Lithium battery chemistries like improved. The Anode materials are the negative electrode in Lithium-ion batteries. The Anode act as the host for Lithium-ion. Predominately Graphite is used as Anode material in Lithium-ion batteries. But Graphite has very low specific capacity (just 372 mah/g) & low ionic & electronic conductivity
It’s the Anode where there is a great possibility of improvement.
Scalability of the Product & Technology:
We use our proprietary equipment ORION 755 is the largest nano synthesizer in the world; specially designed for the mass production of Dawson Nano+ Silicon powder.
Excellent performance:
Dawson Nano+ Silicon powder is of highpurity (99.95% pure) and coated with high-quality graphene which enhances high cyclability, high charge & discharge acceptance.
Triple Anode Protection:
Silicon is the most preferred & desirable Anode for all Lithium-ion cell & battery manufacturers but the Silicon Anode suffered from inherent shortcomings of volume expansion (300%) after charging of cells and quality degradation when it comes in contact with electrolyte. This volume expansion causes the breaking of the Anode and causes premature battery failure. At Dawson Group, we protect our Silicon Anode by applying porous Graphene coating & specially designed Binder. This coating forms a strong protection layer on the surface of Silicon particles and the Binder prevents volume expansion. Graphene coating also protects the Silicon Anode to come in direct contact with electrolyte and electrolyte penetration.
