Summary

Summary: 
A non-profit Spanish research institute from Madrid has developed a novel inexpensive and scalable molecular reactor method for the synthesis of 2D metal oxides (Co3O4, Fe2O3, MnO2, NiO etc). These nanosheets demonstrated excellent Li-ion storage performance when tested as anode material in Rechargeable Li-ion batteries. The cooperation types are license agreements and technical cooperation agreements.

Description

Description: 

Secondary lithium-ion batteries (LIBs) attracted tremendous interest due to their high energy density, good cycle life, and efficiency compared to Pb-acid, Ni-MH and Ni-Cd batteries. Natural/ synthetic graphite is commonly used as anode for Li-ion batteries due to its low volume change during the charge-discharge process. However, graphite anode is not suitable for a number of high energy/ power applications due to low specific capacity (< 372 mAh/g), and sluggish diffusion of Li-ions into the individual graphene layers. Lithium intercalation of graphite anodes at lower potentials (<0.3V vs Li+/Li) also causes Li-dendrite growth and challenges the overall safety of Li-ion batteries.

These drawbacks of graphite anodes triggered extensive research focused on the development of alternative high-performance anode materials. Carbonaceous and metal oxide 2D materials are promising candidates for Li-ion storage due to their unique Physical and chemical properties. However, their large scale synthesis is a great challenge that is hindering the commercialization of energy storage devices based on 2D electrode materials.

They are looking for partners/ collaborators for license agreements and technical cooperation agreements in the area of energy storage and batteries who are capable of: for scaling up of the synthesis of newly developed 2D-metal oxide anode materials, the fabrication of pouch and cylindrical type Li-ion batteries with this 2D-metal oxide anodes and its commercialization

Advantages & innovations

Cooperation plus value: 
They have developed a novel inexpensive and scalable molecular reactor method for the synthesis of 2D metal oxides (Co3O4, Fe2O3, MnO2, NiO etc). These nanosheets demonstrated excellent Li-ion storage performance when tested as anode material in Rechargeable Li-ion batteries. 2D morphology and hierarchical microstructure of the metal oxide nanosheets resulted in superior contact with electrolyte solution and ultrafast Li-ion diffusion, resulting in a pseudocapacitive type Li-ion storage mechanism. It has high capacity (up to 15000 mAh/g) anodes capable of operation under high current densities (up to 15 A/g) can be synthesized through this method. The strategy of metal oxide nanosheet formation in a molecular reactor can also be extended for other simple and complex metal oxides.
