Description

Li-ion cells, as used in prior-art, continue to have poor material utilization even in cells

designed for high energy density. Current electrodes, mainly due to lack of appropriate

thickness, are associated with low volume and mass efficiency apart from high cost. Use

of thicker electrodes has proved to be worse as they lead to increased diffusion

pathways, limiting delivery of stored energy to mere fractions. There have also been

reports about increasing electrode porosity. However, even such methods have their

own drawbacks. The most important one being reduced energy density. This invention

relates to a novel technique for development and use of low tortuous battery electrodes, capable of overcoming most prior-art limitations and/or unmet needs.

 

Value Proposition

⁰ The electrodes:

• Are more economical as compared to conventional electrodes

• Are fabricated using a flexible method that is scalable and can be used with many materials

• Have aligned pore channels with a lower tortuosity that are capable of controlling alignment

of magnetic and non-magnetic phases

• Deliver more capacity at high discharge rates as compared to electrodes with conventional

microstructures

• Would be commercially useful for the following applications:

⁰ As cathodes for lithium-ion batteries of electric and hybrid vehicles

⁰ As Anodes for lithium-ion batteries of electric and hybrid vehicles

⁰ Any other application requiring high energy density
