Aiding India’s green mobility transition

Aiding India’s green mobility transition

India’s green energy transition is largely dependent on Lithium-ion battery chemistry. The elements used in Lithium-ion battery are scarce in India. A 10 GWh of battery manufacturing will require 150 TPA of Lithium element, 375 TPA of Cobalt and Nickel.

Rubamin aims to provide a circular life cycle management solution for Lithium-Ion batteries.

Critical elements for battery manufacturing through closed loop recycling of Lithium-Ion Battery

Lithium-Ion Batteries recycling is a natural extension of Rubamin’s core competence and Hydrometallurgical experience. Our existing circular recycling operations for spent catalyst can easily be adapted to process Lithium-Ion Battery (LIB) Black Mass as an alternate feed.

Rubamin’s R&D team has developed and tested the process of LIB Black Mass Recycling for recovery of all metals such as Lithium, Nickel, Cobalt & Manganese. It enables recycling for all chemistries of lithium-ion batteries (LCO, NMC, LMO, NCA, and LFP).

Our proprietary technology can recover these metals into their purest battery-grade form in an eco-efficient way. These valuable metals can be reused into active cathode materials for new batteries.

Rubamin’s Hydromet Advantage

Pyrometallurgy based operations generate residues to be landfilled, lose metals during processing, reduce realizable value of metals and impact environment from the energy-intensive process. On the other hand, Rubamin’s Hydrometallurgical processes are waste-free, recover all metals, enhance value addition due to purity of end products and have minimal impact on the environment.

Because hydrometallurgical processes can be complicated to implement, they aren’t typically the first choice for recycling Li-Ion Batteries. Hydromet Units require large area due to multiplicity of processing steps, high capital expenditure and highly flexible production processes to take care of the variable feed. Also, the use of large quantity of water, resulting effluents and solid waste generation has limited its practice across the globe.

Rubamin has been practicing Hydrometallurgy for last three decades. Overtime, with inhouse research and innovations, we have eradicated the effluent and solid waste through secondary processing and value addition. We have even developed a large rainwater lake for process water needs to remove dependence on river water. Our co-located and fully Integrated R&D have lent flexibility to operations to handle heterogenous feed.

Rubamin finds itself well poised to use the expertise developed through decades of practice, experience and research for recycling Li-Ion Batteries Black Mass in the most eco-friendly and cost-effective manner. Being aware of this opportunity and mega-trend we are investing heavily in research, process plant and infrastructure to superimpose Li-Ion Battery recycling in our existing Green Recycling Complex.

Why sustainable LIB recycling is crucial for India?

Transition to green energy & net zero future is dependent on the availability of key elements such as Cobalt, Lithium, Nickel, Manganese and Graphite, Not just India but the world is deficient looking to the looming demand in near future.

At the same time production of batteries results in 5-10% manufacturing scrap which needs to be channelized back to production process for reducing cost of EV Battery. This is in addition to the end-of-life battery waste expected in near future which can provide much needed scarce metal resources. However, sustainable Li-Ion battery recycling is the missing link in the battery supply chain.

Rubamin has the eco-friendly recycling competence and know-how that can provide a substantial quantity of these metals to Indian industry as well as internationally for manufacturing of Lithium-Ion Battery.
