:: Producing Lithium-Ion Batteries Without the Hassle of Lithium Hydroxide


Lithium Australia’s revolutionary SiLeach® process has produced trilithium phosphate, thereby reducing the need to concentrate solutions generated by the processing of lithium micas. With no further refining, that phosphate has been used to create lithium-iron-phosphate (LFP) batteries, the performance of which compares favourably with that of other high-performance LFP products made by VSPC, a Lithium Australia subsidiary, at its electrochemical facility in Queensland.

As Lithium Australia has stated, the process – designed to precipitate lithium from low-grade solutions – may also be key to recovering lithium from brine without evaporation. Moreover, as with the product produced by SiLeach®, the resulting chemicals could allow lithium from brines to be processed through to cathode powders without the need for an intermediate lithium carbonate or lithium hydroxide product.
