TECHNOLOGY OVERVIEW

Lithium-ion batteries is a US$40.5B dollar industry that has seen massive growth in recent years due to increasing demand for energy storage devices. However, one of the main issues with lithium-ion batteries is safety, with emphasis on chemical fires that is the result of short circuits caused by lithium dendrites built-up and growth. To date, this is still an existing problem with no viable solution offered yet.

This technology offer is a proprietary anti-short circuit layer that can prevent chemical fires by stopping further lithium dendritic growth once these dendrites encounter the anti-short circuit layer. It has shown to be able to eliminate the risk of short-circuits completely for the entire life cycle of the battery. The application of the layer had no impact on the performance of the battery and is viable for almost all different compositions of lithium-ion batteries. Furthermore, addition of this layer only adds less than 5% (can be further reduced) to the total production cost with no changes to the manufacturing line.

TECHNOLOGY FEATURES & SPECIFICATIONS

This technology is a conductive layer which is added onto the separator of the lithium-ion battery. Features of this technology are as follows:

  • Completely eliminate chemical fires resulting from short-circuit
  • Able to last for entire life cycle of battery
  • No impact on battery performance
  • Suitable for almost all lithium-ion battery compositions (50 different compositions)

POTENTIAL APPLICATIONS

The uses of this technology are for industries that have heavy reliance on lithium-ion batteries.

Potential applications include (but are not limited to):

  • Mobile devices (handphones, tablets, portable chargers)
  • Electric vehicles (EVs, PMDs)
  • Drones
  • Battery charging stations

The technology owner is keen to out-license this technology to lithium-ion battery developers and manufacturers, or developers and manufacturers of lithium-ion battery separators.

Market Trends & Opportunities

The lithium-ion battery market is expected to grow at a CAGR of 12.3% to be worth US$116.6B by 2030. This technology could potentially eliminate a long-standing safety issue that has been plaguing this market since conception.

Benefits

  • Cost effective (less than 5% cost addition)
  • Easy adaptation to lithium-ion battery manufacturing line
  • No additional materials required (sourced directly from the production line)
