Distributed Storage

Researchers at Monash University have published a new study in which high voltage lithium batteries, such as those used in electric vehicles and grid scale energy storage systems, are tested with a novel lithium salt shown to be far less hazardous than current conventional materials.

Three PhD students from Melbourne are moving their research into recycling lithium-ion batteries from the labs into pitch meetings, vying to become one of the first companies in Australia to recover the metals and minerals from spent batteries. Their method, they say, is simpler, less toxic and more cost competitive than those widely used.

LG Energy Solution has agreed to take 100% of the cobalt and nickel from the proposed Sconi Project in Queensland. The company says the deal will give it an “upper hand” in EV battery production and improve its ESG competitiveness.

German scientists have applied a new combination of cathodes and electrolytes to improve the stability of lithium-metal batteries. They fabricated a device with an energy density of 560 watt-hours per kilogram and a Coulombic efficiency of 99.94%.

Japanese scientists have developed a new lithium-sulfur battery by using titanium oxide and titanium nitride to prevent the formation of polysulfides during the fabrication process. This allows the battery to retain 85% of its capacity after 500 cycles at 2 C.

Ambri has secured US$144 million ( AU$195 million) to commercialise its calcium-antimony liquid metal battery chemistry and open manufacturing facilities to deliver projects in 2023 and beyond.

Energy Source, a Brazilian battery specialist, is currently providing energy storage services with reused and recycled batteries. Battery recycling and related metals recovery are conducted separately, without the burning of materials.

PV electricity generation is a natural choice for Australia’s remote Kimberley region. State-owned energy provider Horizon Power has deployed WA Recovery Plan funds to make the most of the interplay between sun and shade and put clean energy behind the Derby community’s aspirations.

Processing nightmare, or product opportunity? Impending five-minute settlement comes at a difficult time for energy retailers. Software from across the ditch could help highlight the benefits and opportunities of more solar and a forecast uptick in battery energy storage.

With manufacturing ramping up year by year and policies already looking to get ahead of the large volumes of end-of-life products, the landscape for lithium-ion battery recycling is rapidly changing. pv magazine recently spoke with Mari Lundström, associate professor of chemical and metallurgical engineering at Aalto University, to find out what is needed on the research side for the effective recycling of batteries.
