WHAT IS MANGANESE SULPHATE?

What is Manganese Sulphate?

• Mn transitional metal – known for distinct properties e.g. Ductile,

malleable and able to conduct electricity and heat.

• Manganese is digested with Sulphuric Acid then purified to produce a

high-quality product.

• A light pink salt used in some cathode structures of Lithium ion

batteries.

• Can be used to produce EMD used in Alkaline Batteries (AA/AAA).
• High purity manganese sulphate currently takes up 10% of global Mn

market, but accounts for 40% of its global market value.

CATHODE STRUCTURES USING MANGANESE SULPHATE

www.pilbarametalsgroup.com

Cathode structures using Manganese Sulphate

• LMO contains 4% Lithium, 61% Manganese and 35% Oxygen.
• Various structures of NMC being utilized.
• SK Innovations: NMC 811 for the Kia Niro is delayed until 2019,

NMC 622 structure still being utilized.

• China’s electric buses are now using NMC in favour of LFP. (Source:

IDTech Ex Ltd).

• Manganese favoured due to low commodity costs, stability, and

conductivity.

DEMAND FOR MANGANESE SULPHATE IN CATHODES

www.pilbarametalsgroup.com

Demand for Manganese Sulphate in Cathodes

• Cathode is the most expensive component of Lithium-Ion Batteries.
• Demand rising as companies seek alternative cathode material to

bring costs down.

• Strong market for Manganese with steel and battery industry.
• NMC to have the biggest market.
• LMO to have the largest growth (4x).
• Some electric vehicles using manganese cathode structures – BMW

LMO and NMC (i3 and i8), Nissan LMO (Leaf), Rimac NMC (C-two).

• Various battery storage systems like Tesla’s are using the NMC

cathode, Tesla use NMC due to its long life cycle and cost.

PMG’S PROCESS

www.pilbarametalsgroup.com

PMG’s process

• Low environmental impact.
• Utilising proven technology – Digestion with Sulfuric Acid.
• Own IP for the front-end process turning MnO2 to MnO.
• Own IP for the purification.
• Patents pending upon completion of final testwork.
• Utilise local companies waste and by products.
• By products saleable – Ferric Oxide, Silica Sand.
