- Lithium Australia is seeking intellectual property protection for its battery recycling process.
- The provisional PCT application with IP Australia is related to the recycling and recovery of electrode materials from alkaline batteries.
- The alkaline battery separation process was used by Envirostream Australia, a 90%-owned subsidiary of LIT, to generate samples for the field trial programme in 2021.
In a strategic move, Lithium Australia NL (ASX:LIT) has filed a provisional Patent Cooperation Treaty (PCT) application with IP Australia. The application concerns the recycling process for alkaline batteries, developed by the Company’s 90%-owned subsidiary Envirostream Australia Pty Ltd.
Envirostream is among the pioneers working in the field of recycling of electrode materials from alkaline batteries.
The PCT application - Process for recovering values from alkaline batteries - describes the processes for the separation of electrode materials comprising cathode and anode from alkaline batteries.
2021 field trial programme
The recycling division of LIT, Envirostream, commenced its field trial programme to use recycled alkaline battery material as a fertiliser micronutrient in June 2021.
LIT teamed up with Summit Fertilizers, which is a leading fertiliser supplier in WA. Summit provided access to three of its trial sites in WA. Two of them had wheat, while the third one had lupins.
The trial included one dedicated Envirostream site in WA and one in South Australia, taking the total number of sites to five for the field trials.
Envirostream developed two mono-ammonium phosphate (MAP) product options derived from its proprietary separation technology. Any differences in the performance of the two options were assessed in the field trials.

Leading edge in battery recycling
The recycling of alkaline batteries is in line with Lithium Australia’s objective to establish a circular battery economy. The leading-edge battery recycling technology will help in diverting end-of-life batteries from landfills.
LIT continues its research into the development of extraction processes for the conversion of all lithium silicates, including mine waste to lithium chemicals, in order to produce advanced cathode materials for the battery industry, globally.
The Company is uniting resources and innovation to vertically integrate lithium extraction, processing, and recycling.
This contribution by the Company has been recognised by the federal government in the form of substantial research grants.
