Cam­poona graphite put to the test

The Australian Mining Review - - NEWS: TECHNOLOGY & INNOVATION - JES­SICA CUM­MINS

ARCHER Ex­plo­ration, in part­ner­ship with The Univer­sity of New South Wales (UNSW), has de­vel­oped full-cell lithium-ion bat­ter­ies suit­able for use in the elec­tric ve­hi­cle and con­sumer elec­tri­cal mar­kets.

The bat­ter­ies com­prise three com­monly used cath­ode vari­ants: lithium- nick­el­man­ganese-cobalt (NMC), lithium-iron phos­phate (LFP), and lithium-cobalt ox­ide (LCO), as well as graphite from Archer’s Cam­poona project on the Eyre Peninsula.

Archer chief ex­ec­u­tive of­fi­cer Dr Mo­ham­mad Chou­cair said the speed at which the com­pany de­liv­ered the tech­nol­ogy was tes­ta­ment to the strong tech­ni­cal lead­er­ship cul­ture at Archer.

“Col­lab­o­ra­tion with UNSW has greatly ac­cel­er­ated our ad­vance in the bat­tery space,” Dr Chou­cair said.

“We are now able to demon­strate com­plete, func­tion­ing, and com­mer­cially rel­e­vant bat­ter­ies with Archer’s graphite.

“We have reached a ma­jor mile­stone towards in­te­grat­ing our sub­stan­tial graphite re­source in the lithium-ion bat­tery sup­ply chain.”

Dr Chou­cair said all syn­the­sis, fab­ri­ca­tion, char­ac­ter­i­sa­tion and test­ing was car­ried out at UNSW.

“The work defini­tively shows that Archer’s graphite can be used in con­junc­tion with dif­fer­ent types of cath­odes, mak­ing it suit­able for mul­ti­ple po­ten­tial bat­tery mar­kets,” he said.

The next steps for Archer in­volved ad­dress­ing the trade-off between cost and bat­tery per­for­mance and build­ing off scal­able proof-of-pro­duc­tion as it con­tin­ues to tar­get part­ner­ships with lithium ion bat­tery man­u­fac­tur­ers.
