Battery grade materials from spent catalysts, sludge’s, secondary’s, effluents,
primary and low-grade ores

Advantages / Salient Technical Features Scale of Development
• Battery grade materials such as Electrolytic • Pilot scale studies on preparation of
Manganese Dioxide (EMD), Nickel hydroxide, Cobalt Electrolytic Manganese Dioxide (EMD) from
hydroxide / oxide as per standards low grade resources.
• Process flow sheets developed for recovery
Problem being addressed of EMD, nickel hydroxide and cobalt
• Indigenous process for production of battery grade hydroxide/oxide from various secondary
materials resources and spent catalysts. (Current TRL
Level : 06/07)
• Import Substitution
• Fulfilment of Aatma Nirbhar Commercialization Status

• Basic Engineering Package provided for
Environmental Considerations (if any) 10,000 TPA EMD production from Mn Ore,
• Employs hydrometallurgical unit operations which MOIL, Nagpur
are environmentally benign processes. • Nickel hydroxide from secondary resources

• Cobalt hydroxide / oxide from secondary
Major Raw Materials to be Utilized resources
• Spent catalysts, sludge’s, secondary’s, effluents,
primary and low-grade ores. Commercial grade Techno-economics
chemicals will be used in the process.
• Return on Investment 20-40%
