Summary

This Testing the Performance of Lithium Ion Batteries project is analysing the performance of eighteen leading batteries, comparing major lithium-ion battery brands to existing and advanced lead-acid battery technologies, as well as novel a zinc-bromide flow battery and an aqueous hybrid ion battery.

The purpose of the project is to verify claims made by manufacturers about performance, integration, and installation of battery packs, and to disseminate the results to the public. To achieve this ITP is independently testing the performance of each battery side by side in hot daytime and cool overnight temperatures, similar to what they would be expected to face in real-world conditions. Testing takes place in a climate-controlled enclosure at the Canberra Institute of Technology.

As the batteries are cycled they lose the ability to store as much energy as when they were new. The key objective of the testing is therefore to measure the batteries’ decrease in storage capacity over time and with energy throughput.

In view of the strong and growing interest in battery storage ARENA increased funding for this project which will now see an additional 10 batteries to be tested.

Battery cycling has been ongoing since August 2016, and will continue until the end of June 2020 and now involves 18 batteries being put through their paces.

All batteries were selected because they were commercially available and covered a spectrum of prices and chemistry variants. To ensure independence all batteries were purchased at full retail prices, primarily from third party distributors.

Users and industry were consulted in the design a testing regime and data structure in order to maximise the value of the findings. This will broaden the understanding of various emerging storage technologies, guiding how they can best be adopted as they increasingly compete with conventional lead-acid batteries on cost and reliability.

The results will be shared broadly across the energy industry with investors, power companies, researchers and consumers. The provision of independent data and analysis will inform and improve investment decisions about the future impact of both grid-connected and remote power system battery storage.
