Scrapping the waste export levy could threaten Australia’s emerging lithium battery recycling industry

As electric vehicle (EV) demand accelerates, so does the need for lithium batteries. But these batteries contain valuable critical minerals, as well as toxic materials, so they should not be treated as common waste.

Unlike China and some European countries, Australia lacks a dedicated lithium battery recycling facility. Just 10% of Australia’s lithium battery waste was “recycled” in 2021. This means the batteries were collected and shredded locally before being sent overseas for recycling.

Shipping large volumes of spent batteries overseas is complex and risky. Lithium batteries have been known to start fires. A cargo ship laden with lithium batteries caught fire off the coast of Alaska in December 2023. The fire burned for days.

Similarly, a fire broke out on a cargo ship carrying luxury vehicles (including EVs) near Portugal’s Azores Islands in February 2022. The risk of fire is even greater for spent EV batteries because they are more likely to be damaged or unsafe.

Efforts to recycle batteries onshore have now been jeopardized by the decision—announced last week ahead of this week’s federal budget—to scrap plans for a waste export levy. The proposed A$4 per ton levy on waste exports would have come into effect on July 1.

Scrapping the levy will pave the way for even more waste to be exported rather than recycled here. We believe there should be exceptions for spent lithium batteries—for several reasons. These include safety concerns around shipping and the loss of critical minerals.

By recycling onshore, we can retain these resources, build new industries and develop a circular economy. We should also prepare for the possibility that other countries will at some stage refuse to accept our waste. Then we will be forced to stockpile these batteries, at great risk.

Lithium batteries

Spent EV batteries are accumulating rapidly

EV sales are growing exponentially. Globally, one in five new cars are electric. More than half of all cars sold by 2040 will likely be EVs.

Beneath each sleek exterior is a hefty lithium battery with an average lifespan of just five to eight years.

According to the International Energy Agency, EVs generated about 500,000 tons of battery waste in 2019 alone. This waste is forecast to reach 8 million tons by 2040.

A 2016 report for the federal government forecasts at least 20% annual growth in Australian lithium battery waste to 136,000 tons a year by 2036.

CSIRO explored the potential for lithium battery recycling and reuse in 2021. But little has happened since.

Meanwhile, the mountain of waste continues to grow. It is estimated 360,000 tons of EV batteries will be spent by 2040 and 1.6 million tons by 2050.

Battery recycling is a must, not a choice

Disposal of lithium batteries can cause fires and explosions in waste management facilities and landfills. If a battery is punctured, or short-circuits, the residual electricity can spark fires or explode. The batteries can also leak metals such as cobalt, nickel or manganese, threatening ecosystems and human health.

The battery fluid is harmful to humans as it is linked to various health effects including heart attacks, asthma, cancer, eye damage, reproductive toxicity, skin sensitisation, damage to bones and kidneys and other symptoms.

Lithium battery wastes are overground mines

Rather than being seen as a liability, the growing pile of spent lithium batteries could represent an economic opportunity for Australia. The battery pack in a BMW i3 electric vehicle, for example, contains 6kg of lithium, 35kg of graphite, 2kg of cobalt, 12kg of nickel and 12kg of manganese. These valuable resources will be wasted if the batteries are exported or sent to landfill.

If the raw materials were instead recovered and processed onshore, this could translate into a burgeoning industry worth A$3.1 billion, using Australia’s existing expertise in mining and resource recovery.

new energy battery

It’s time to get serious about battery recycling

The federal government missed an opportunity to include infrastructure for battery recycling in its A$250 million Recycling Modernisation Fund. These funds were limited to waste glass, plastic, tires, paper and cardboard.

This delays the establishment of onshore capacity for battery recycling and makes us reliant on exporting waste batteries overseas.

To boost recycling, we must develop clear regulations and guidelines aligned with global standards, including stringent restrictions on landfill.

In addition, incentives such as tax credits and rebates for battery recycling programs will encourage investment in this area and drive progress. Such measures in Europe make the legislated target for lithium recovery from waste batteries (63% by 2027) possible, cutting reliance on imports of raw materials.

We urgently need to develop a comprehensive waste management strategy dedicated to the responsible collection and recycling of waste batteries. Such a strategy is crucial to safeguard both the environment and communities from the potential hazards associated with improper disposal, promoting resource conservation and creating a circular economy for these critical energy storage devices.

Cost-effective, high-capacity and cyclable lithium-ion battery cathodes

LiTypes of Lithium-ion

Charge-recharge cycling of lithium-super-rich iron oxide, a cost-effective and high-capacity cathode for new-generation lithium-ion batteries, can be greatly improved by doping with readily available mineral elements.

The energy capacity and charge-recharge cycling (cyclability) of lithium-iron-oxide, a cost-effective cathode material for rechargeable lithium-ion batteries, is improved by adding small amounts of abundant elements. The development, achieved by researchers at Hokkaido University, Tohoku University, and Nagoya Institute of Technology, is reported in the journal ACS Materials Letters.

Lithium ion batteries have become indispensable in modern life, used in a multitude of applications including mobile phones, electric vehicles, and large power storage systems.

A constant research effort is underway to increase their capacity, efficiency, and sustainability. A major challenge is to reduce the reliance on rare and expensive resources. One approach is to use more efficient and sustainable materials for the battery cathodes, where key electron exchange processes occur.

The researchers worked to improve the performance of cathodes based on a particular lithium-iron-oxide compound. In 2023, they reported a promising cathode material, Li5FeO4, that exhibits a high capacity using iron and oxygen redox reactions. However, its development encountered problems associated with the production of oxygen during charging-recharging cycling.

“We have now found that the cyclability could be significantly enhanced by doping small amounts of abundantly available elements such as aluminum, silicon, phosphorus, and sulfur into the cathode’s crystal structure,” says Associate Professor Hiroaki Kobayashi at the Department of Chemistry, Faculty of Science, Hokkaido University.

18500 3.7v 1100mah Lithium battery

A crucial chemical aspect of the enhancement proved to be the formation of strong ‘covalent’ bonds between the dopant and oxygen atoms within the structure. These bonds hold atoms together when electrons are shared between the atoms, rather than the ‘ionic’ interaction between positive and negatively charged ions.

“The covalent bonding between the dopant and oxygen atoms makes the problematic release of oxygen less energetically favorable, and therefore less likely to occur,” says Kobayashi.

The researchers used X-ray absorption analysis and theoretical calculations to explore the fine details of changes in the structure of the cathode material caused by introducing different dopant elements. This allowed them to propose theoretical explanations for the improvements they observed. They also used electrochemical analysis to quantify the improvements in the cathode’s energy capacity, stability and the cycling between charging and discharging phases, showing an increase in capacity retention from 50% to 90%.

“We will continue to develop these new insights, hoping to make a significant contribution to the advances in battery technology that will be crucial if electric power is to widely replace fossil fuel use, as required by global efforts to combat climate change,” Kobayashi concludes.

The next phase of the research will include exploring the challenges and possibilities in scaling up the methods into technology ready for commercialization.
