Abstract
Energy storage has an important role to play in addressing global warming. It is vital to develop a number of storage technologies. One of the most promising is the rechargeable lithium battery. Such batteries are the technology of choice for hybrid electrical vehicles (some 30% of CO2 emissions arise from transport) and they can make a critical contribution to the storage of clean energy, including for micro-grid and off-grid applications.Currently rechargeable lithium batteries are composed of a graphite negative electrode, an organic electrolyte and LiCoO2 as the positive electrode. Li is removed from the layered intercalation compound LiCoO2 on charging and re-inserted on discharge. Energy storage is limited by the LiCoO2 electrode (0.5 Li/Co, 130 mAhg-1). All the research taking place worldwide aimed at improving the positive intercalation electrode can only hope to double the energy storage to 1 Li/Tm (300 mAhg-1). We propose a step change in rechargeable lithium batteries by replacing the LiCoO2 electrode with a porous carbon electrode and allowing Li+ and e- in the cell to react with O2 from the air. The capacity to store energy can be raised by 5-10 times compared with LiCoO2, supply of O2 is in-effect infinite and the cost is reduced significantly (LiCoO2 is the most expensive component of current batteries). Our preliminary studies have shown that the O2 cell is rechargeable and can sustain cycling. The proposal addresses a number of the materials issues necessary to realise this radically new high energy storage battery based on a non-aqueous O2 electrode.

Description | This research focused on the development of a new generation of batteries, known as the lithium air battery, which has the potential to exceed the performance of the popular lithium ion battery. This technology was relatively unknown at the time the grant was awarded and is now one of the leading contenders to supersede lithium ion batteries and provide a new generation of energy storage device. The work funded by this grant established many of the key concepts of this battery system, and these principles continue to direct the field to date. Specifically, this work defined the operation and approach of the field and identified the core materials and battery design. Metal oxide catalysts for the oxygen redox reactions were established and this has spawned a range of commercially relevant battery materials for metal air batteries. Critically, interest in lithium air batteries has growth expernenionally in large part due to the work performed here and is now a major development theme and potential growth area for a number of large industries. |
Exploitation Route | The findings performed here help to establish a large international research field centered on metal air batteries and related industrial involvement. For example, IBM and |Toyota both have significant research investments in this area in part due to this work and the findings produced here form a foundation for the development of next generation energy storage batteries for electrified transport. |
Sectors | Energy Transport |
Description | The research aided establishment of research links and collaboration between the Bruce group and a number of leading international car manufacturers which are ongoing, and support the development of new battery systems and related industries. Generally, the field of metal air batteries established by this work is a major development area globally in the private sector as it represents one of a handful of possible routes to batteries with performance exceeding lithium ion technology. |
