In Queensland released an article today titled Novonix breakthrough could deliver the EV magic bullet - the 100-year battery

https://inqld.com.au/business/2022/06/01/novonix-breakthrough-could-deliver-the-ev-magic-bullet-the-100-year-battery/

Apparently Dr Jeff Dahn and Tesla's research team released a paper on a nickel-based battery that could last 100 years and still favourably compare to lithium iron phosphate cells.

Dr Jeff Dahn is Novonix's chief scientific officer but aside from this I'm not sure what it really has to do with Novonix. Keep in mind it's only theoretical at this stage and there are concerns around cost with speculation these batteries may be more suited to long-term energy storage than for EVs. And of course media outlets are notoriously horrible at interpreting (sensationalising?) scientific papers. I haven't read the paper myself, nor would I likely understand it, but if it proves achievable it would certainly disrupt the industry and potentially solve the EV battery recycling dilemma.

Has anyone been watching the development of the Zinc/Bromide battery as featured on the ABC News last night (9/09.2021)??

Appaerntly the advantages is the ability to get 100% charge/discharge over multiple cycles.

Production trials to begin shortly in Western Sydney ......... might be something to keep an eye on

See my straw on RFX competitors.

The company is Gelion

Interesting Macca571 thanks for that.  Zinc-Bromide could be the answer for high durability applications (where both high cycle length >2000 and temperature durability are important).

 

Personally I've been interested in the new Lithium-Sulphur battery technology being developed by LI-S energy in conjunction with PPK group, Deakin University and BNNT Technology Limited.  This technology has a big advantage of having an energy density of 550 Wh/L which is about 5 times that of current lithium ion technology.  LI-S energy (LIS) is poised to shortly float on the asx.  Their IPO was heavily over subscribed and it appears initial stock allocation has been significantly limited.

What's the energy density of the best batteries we have vs that of hydrogen?
