Battery Materials & Chemicals

Due to sodium’s abundance within the earth’s crust, Na-ion battery technology is a new and fast-growing Energy Research area.

Following the increase in demand, we have all the materials, chemicals, components and equipment you need to help accelerate your Na-ion battery research:

‍

‍Discs & Foils

Our discs are pre-cut to size for ease of use within coin cell research, whilst the foil can be cut to size for use in pouch or cylinder cell R&D

‍Sodium Discs:

• Diameter: 12.0mm, 14.0mm, 15.6mm, 18.0mm
• Thickness: 0.45mm
• Coating: Coated on one side with 30μm aluminium to aid current collection, also available uncoated if required.

‍

‍Sodium Foil:

• Purity: 99.7%
• Dimensions: 120mm x 300mm
• Thickness: 0.45mm
• Coating: Coated on one side with 30μm aluminium to aid current collection 

Anode & Cathode Powders

Our sodium-ion cathode materials are typically based on intercalation / de-intercalation compounds, where sodium ions provided by the cathode are inserted into the host lattice (anode) during charge and extracted during discharge, with minimal structural change in the host material

Na-ion Cathode, Anode, and Electrolyte Powders

We supply a variety of sodium-ion battery materials, which include sodium-based cathode and anode materials, their corresponding carbon-coated counterparts (3-5 wt.% carbon),and sodium-based solid electrolytes.

We can customize the primary and secondary particle size, composition, and surface characteristics (e.g. electronically conducting coating layer) of available materials, as well as custom synthesize Na-ion materials upon request.  

Electrolytes

Our electrolytes have been specifically formulated for na-ion battery research - please contact us for more information.

‍

Pre-Coated Electrode Sheets

Na-ion Cathode and Anode Electrode Sheets

Our sodium-ion cathode and anode powders can also be cast as an electrode sheet, as shown below:

• Coated Sheet Dimensions: 5inches x 10 inches (127 mm x 254 mm)
• Current Collectors: Copper (10 μm) or Aluminium (16 μm)
• Coating: Single and Double-sided sheets available, coated edge-to-edge (unless specified otherwise)
• Standard*Composition: 85% active material, 10% conductive carbon, 5% PVDF binder (*except Hard Carbon electrode sheet

Modifications can also be made to accommodate customers with unique specification requirements, such as different active material loadings, coating thickness, and binder type / content upon request.

New in the Sodium-ion pre-coated electrode range is the Sodium Ferric Pyrophosphate (Na₃Fe₂(PO₄)P₂O₇) electrode sheets. NFPP has emerged as an attractive cathode material for sodium-ion batteries. The advantages of NFPP mirror that of LiFePO₄ (LFP) in lithium-ion batteries.
