Nickel(III) Oxyhydroxide (NiOOH) as a Positive Electrode Material in Primary Cells. In recent years, the demands put on batteries has increased due to the development of sophisticated portable electronic devices. With the currently available primary battery systems finding it difficult to cope with these demands, there is considerable incentive to develop an improved system with an appropriate capability.

In recent years, the demands put on batteries has increased due to the development of sophisticated portable electronic devices. With the currently available primary battery systems finding it difficult to cope with these demands, there is considerable incentive to develop an improved system with an appropriate capability. This project focuses on nickel(III) oxyhydroxide (NiOOH) as a cathode material. NiOOH is used widely in rechargeable battery systems, where it performs adequately even under severe discharge conditions. However, in primary battery systems, NiOOH suffers from self discharge. This project aims to use the performance capabilities of NiOOH in a primary system, by investigating ways to improve its stability. The benefits for Delta EMD will be protection of their existing business, as well as opening the door to the commercial manufacture of an advanced export material.Read moreRead less
Capacitance Fade Mechanisms in Carbon-Based Supercapacitors. Energy storage is of significant importance to the global community. This project addresses certain performance issues concerning prolonged energy storage in supercapacitors, which are an emerging technology in the electronics industry. CAP-XX is Australia's only manufacturer of supercapacitors, and the improvements to their products that will result from this work, will lead to significant returns to them and the Australian economy.
Development of novel cathodes for next generation solid oxide fuel cells. This project will provide novel cathodes to reduce the operating temperature of the Solid Oxide Fuel Cell (SOFC) as low as 500 degrees celsius. The technology may lead to widespread utilization of SOFCs, thus providing great assistance to Australia's industries in term of reducing carbon dioxide emission and easing pressure from carbon tax.
Solid-State Battery Interface Design (SS-BID). This research project aims to use the world’s best performing solid-state ion conductors to develop next generation solid-state batteries. Boron-rich electrolytes will be paired with lithium metal anodes to construct batteries that are more energy dense, safer, have wider operational temperature windows, and aim to be lower cost than existing Li-ion batteries. The current roadblock for these batteries lies in the poorly performing interfaces between ....Solid-State Battery Interface Design (SS-BID).

Boron-rich electrolytes will be paired with lithium metal anodes to construct batteries that are more energy dense, safer, have wider operational temperature windows, and aim to be lower cost than existing Li-ion batteries. The current roadblock for these batteries lies in the poorly performing interfaces between anode, electrolyte and cathode. This research aims to develop new strategies to overcome these barriers and perform world-class measurement techniques to understand and optimise solid-state batteries to provide a commercially viable energy storage solution.Read moreRead less
Hybrid cathode for low temperature solid oxide fuel cells. This project aims to develop molten carbonate-perovskite hybrid cathode materials for low temperature solid oxide fuel cells (LT-SOFCs) possessing both high catalytic activity towards oxygen reduction reaction (ORR) and high tolerance to carbon dioxide poisoning. Carbon dioxide in air can poison nearly all the perovskite cathode materials developed for LT-SOFCs (below 600 degrees C) so far. These materials will not be practically useful ....Hybrid cathode for low temperature solid oxide fuel cells. This project aims to develop molten carbonate-perovskite hybrid cathode materials for low temperature solid oxide fuel cells (LT-SOFCs) possessing both high catalytic activity towards oxygen reduction reaction (ORR) and high tolerance to carbon dioxide poisoning. Carbon dioxide in air can poison nearly all the perovskite cathode materials developed for LT-SOFCs (below 600 degrees C) so far. These materials will not be practically useful until carbon dioxide poisoning can be prevented. This project expects to make these LT-SOFC cathode materials commercially viable, solving a problem for the widespread use of low temperature solid oxide fuel cells.Read moreRead less

Lithium-Ion Conducting Sulfide Cathodes for All-Solid-State Li–S Batteries. The aim of the project is to develop lithium-ion conducting sulphide cathode materials for high-performance all-solid-state lithium-sulphur (Li–S) batteries.
