Improved lithium-ion battery performance with nanofoam metal current collectors

Country of Origin: Singapore
Reference Number: TOSG20190108007
Publication Date: 23 January 2019

Summary

A Singapore academic and research institute has developed novel nanofoam metal current collectors using the ultrasonic synthetic method. They improve the performance of lithium-ion batteries, resulting in better charge/discharge rates in lithium-ion batteries. 

The institute is keen on technology licensing partnerships with MNEs or SMEs of all sizes.

Description

The institute has developed innovative nanofoam metal current collectors using a low cost and scalable ultrasonic method. The nanoporous foam collectors are designed to prepare copper metal for the anode and aluminum or nickel for the cathode of batteries. The nanoporous foam collectors improve the electrochemical retention and cycling stability properties of lithium-ion batteries. 



Based on the results from measurements made on lithium-ion batteries after 500 cycles of charge/discharge, it was concluded that batteries assembled with nanofoam metal current collectors exhibited superior performance of 10.1% compared to commercially available batteries. 



This innovative solution is expected to find applications in electric vehicles and electronic devices. It can also be used as a high surface area catalyst support in various applications. 



The Singapore institute is keen to establish partnerships with industry players such as MNEs or SMEs of all sizes by licensing this technology.

Advantages and Innovations

The benefits offered by ultrasonic chemistry and etching processes are integrated into the design of the nanofoam metal current collectors. 



Lithium-ion batteries integrated with nanofoam metal current collectors exhibit better performance than conventional batteries due to the following:



•	Better cycling stability

•	Better charge holding capacity

Stage Of Development

Under development/lab tested

Requested partner

The Singapore-based institute seeks to partner SMEs of all sizes or MNEs. 



The partner sought could be an industry participant in the electric vehicle, chemical, or electronic device industries, who is keen on exploring partnerships via licensing agreements where the partner could license the technology to further develop and introduce it to its market segments.
