Technology Licensing

IBE™ intends to build on a LIB  manufacturing ecosystem in India.

To facilitate the same, IBE offers a non-exclusive license to mass manufacturing of LIB cells in a phased manner using  IBE’s indigenous LIB  cell chemistry and cell manufacturing know-how, a complete process lines to fabricate cells (Cylindrical (18650, 22700 & 4680), Pouch and Prismatic)

Salient Features of IBE’s LIB formulation

Our LIB formulation is robust and uses aqueous binder slurry technology with CMC/SBR. IBE formulation offers a range of flexibility.  Our licensing includes both PVDF/NMP formulation as well (DUAL BINDER Formulation). Our CMC drying process is versatile and quick, yielding excellent carbon credit to the manufacturers.  No solvent extraction steps are required and/or recycling as it happens for NMP recovery in conventional/Standard LIB cathode formulations.

Our Electrolyte additives are proprietary and serve its important role in cell safety predominantly.  IBE can offer formulations that suit different end-user applications.

Our advanced chemistry provides >2000 Cycles at 0.5C Charge/Discharge pattern with >80% Cell capacity retention.

Our Advanced chemistry formulations include but not limited to:

• Advanced NMC chemistry in which Cathode power consisted of single-crystal NMCxyz powders having larger grain size.
• Standard Polycrystalline secondary particles of NMCxyz for low-cost cells
• Advanced composite Polycrystalline secondary particles of NMCxyz+ (IBE nomenclature) for low-cost cells
• The anode is AG or MCMB powders
• IBE’s Electrolyte blend is robust and proprietary.
• We use a Commercial PP/PE separator of specific thickness.
• Measuring an internal impedance of tens of mΩ (Measured at 1kHz)

Note: Our slurry formulation is unique and versatile to replace any cathode materials (other than NMC811) such as NCP, NMC89, LFP, LCO, and LMN

Our Expertise:

• Significant Experience in cell design & development

• Development & optimisation of cell chemistry (cathode materials, anode materials).

• In-depth knowledge of Li-ion battery cell operation, performance and failure modes.

• Experience in different physical and chemical characterisation tools for AAM and CAM powders, fabricated electrode, and various types of prototype cells.

• Unique Slurry powder mixing sequence

• Slurry viscosity optimisation (visco-elastic properties and pH) and resistivity of the slurry

• Electrode coating and drying sequence for AAM and CAM

What we could offer to Cell manufacturing industry as part of complete Industrialisation drive:

• Qualify anode materials, cathode materials, electrolyte materials, cell components, Separator grade, new electrode compositions in cylindrical, pouch and prismatic cells.
• Optimize the electrode composition, electrode processing, cell assembly processes and cell design parameters to improve the electrochemical and life cycle performances.
• Define specifications for materials, slurry formulations, electrodes, cell subassemblies and final cell. Write DFMEA.
• Define cell design and electrical metrics to meet specific application requirements.
• Define and carry out DVP&R for material and cell qualification.
• Safety Handling as per MSDS
• Support the manufacturing team in the definition of manufacturing procedures.
• Conduct design reviews and, after successful validation, release the design to B or C sample stage.
• Failure Analysis in Lithium-Ion Battery Production with FMEA-Based Large-Scale Bayesian Network
• Determine failure modes and reports are prepared.
• Develop and improve the documentation system and change control and process management procedures.

Salient features of IBE’s Supercapacitor formulation:

• Our proprietary SC formulation is state-of-the-art having unique process steps that use superconductive carbon additives with CMC aqueous   binder facilitating a quick drying process. 
• Our SC chemistry provides Low ESR (as low as 48 mΩ) Supercapacitors with a rated voltage of 2.5-2.7V per cell. 
• The capacitors can be assembled in mF to Several 1000 farads
• Any form-factor can be used. 
• We use a very thin (thickness is a trade secret) proprietary separator.
• Our chosen porous carbon is unique with a high surface area (m²/g)
• Uses a special electrolyte blend with an antigas feature having an ionic conductivity in the range 60-65mS/cm.
