This page belongs to: Action Plan for Critical Technologies
Devices that produce electricity from stored electrochemical energy and tolerate multiple charge and discharge cycles. Electric batteries utilise various materials and chemistries (e.g. lithium-ion (Li-ion), nickel metal hydride (Ni-MH)) battery and form factors (e.g. flow batteries for stationary grid storage, polymer electrolytes for vehicles and personal devices).

Australia's place in the world
China dominates across research impact, venture capital and patents in electric batteries. China has the highest research impact, significantly higher than the rest of the world, including the United States. Chinese research institutions also occupy 4 of the 5 top ranking positions, with the US Department of Energy ranking 3rd. Australia is ranked 5th in the world, with the University of Wollongong our highest ranked institution at 23rd.
Australia is ranked 4th for venture capital (VC) investment globally, behind China, the United States and Japan. Globally, VC investment has been increasing at 34% annually since 2016. Considerably more patents have been lodged by applicants or inventors from China, with almost 4 times as many patents compared to Japan or the United States. Australia ranks 17th.
Australia is a significant producer of important inputs to batteries, including many critical minerals and renewable energy, and has world-class skills and research capability to design and develop battery technology. This situates Australia competitively to service much of worldwide demand for these high-tech goods. As Australia transitions towards renewable energy, we have the opportunity to become a major exporter of renewable energy into our region.
Opportunities and risks
Electric batteries will be crucial in the transition to a renewable energy future. Electric batteries will be essential to power consumer electronics, households, support manufacturing energy needs and enable sustainable transportation. Improved storage capacity, decreased size, extended life and expected reductions in cost will also see an increase in the value of batteries for electricity supply. Australia is well placed to take advantage of the growing demand for electric batteries within our region and globally. Our role in the transition to renewables internationally will be underpinned by our world-class research (including technologies for battery integration and managing battery use to extend operational life), our natural resources and our expanding domestic industry—all of which are required for battery production. The global supply chain for batteries is currently hourglass shaped with central fragility, due to the concentration of processing technologies with a single supplier. Australia is ideally placed to play a key role in addressing this by building alternative supply chains.
Australia must carefully consider and mitigate the end-of-life risks associated with electric batteries, and improve recovery and recycling efforts for components. Whilst greater battery utilisation is a desirable outcome, we must also be aware of potential pressures on our emerging renewable grid and the possibility that battery affordability may be impacted. As batteries become more prevalent, particularly for domestic use, the public must have access to reliable information about best practices around battery use and preservation.
Research impact (RI)
China has the highest research impact in this area, ahead of the United States. Australia is ranked 5th. Total volume of published research has been increasing at 8% p.a. over the 5 year period 2016–2020, with 20% of research involving international collaboration.
- China - 148107
- USA - 50434
- Germany - 18353
- R. of Korea - 18218
- Australia - 10850
The research impact provides an indication of the productivity of a country or institution. Here, productivity was assumed to be represented by the volume of publications (i.e. scholarly output) as an indicator of the resources & facilities, and the level of interest in the publications as an indicator of quality.
China has the highest amount of VC investment for electric batteries, ahead of the United States, and Australia is ranked 4th. Investment in this area has been growing at 34% p.a. since 2016.
Data from Crunchbase. The Crunchbase database provides a partial view of the global VC landscape. However the quantity, quality and richness of the data are considered to be statistically significant, and indicative of global trends.
