A group of chemE's praying for May 8th to come quicker.

Hi everyone! Our project was scaling up the production of a new cobalt-free cathode material for use in electric vehicle battery applications. This cathode material was first reported by researchers in 2020 and has not yet been produced at a large scale. @NU_ChemE #CHME4703Poster

@PyroCycleNEU @NU_ChemE Typically desired purities in the industry are >98% so getting a higher purity would be a goal for optimizing the process. A recycle stream that would take the unreacted metal hydroxides back into the cstr would also help to improve purity and % conversion.

@jabulencia @NU_ChemE The metal hydroxides that precipitated out individually as well as unreacted metal ammonia complexes would be undesired outputs. The nickel hydroxides in particular are of concern because they are known carcinogens.

@CHME4703GROUP20 @NU_ChemE Li-ion batteries are best for applications like EVs and electronics where high energy-density is necessary to make batteries small but powerful. Other applications are possible, but non-lithium batteries will be cheaper or safer when density is not as big of a priority

@CHME4703GROUP20 @NU_ChemE Great project! What do you think the long term effect of the implementation of your project would be? Like will the ocean get measurably cleaner or will the recycled plastic land there again eventually?

@Sasaene @francescowai1 @posterforclass @mustafayev8musa @AlhosaniAhmed_ Looks like some really cool new technology! Medical industry seems like a topical application, but do you see the small form factor being useful in shipping/transportation or electronics? And what are the temperature limits of technology like this compared to vapor-compression?

@always_sunny19 @NU_ChemE Very cool project! I was wondering how effective Gadusol is compared to common active ingredients in sunscreens? Would you be able to tune the amount of Gadusol in your product to make different SPFs of sunscreen?

@RenewbleRubbish @Northeastern @NU_ChemE Great poster Renewable Rubbish! What would be the goal product that your team would produce? Would it be a compact composting system that can be sold as a product to a consumer? Or a larger scaled-up process that produces leachate for sale? What would be the market of either?

@Profess88700345 @NU_ChemE Cool project! Are PFAS the only species captured in GAC beds? If not, what concerns would you have with other possible species participating in these reactions?

@joshuagallaway @NU_ChemE The intention was to replace cobalt-containing high energy-density materials in EVs and portable electronics. Grid storage with NFA is definitely possible but less cost-effective compared to current standards like LFP

[LiNFAO (Team 3) @li_nfao]

@Sasaene @NU_ChemE The statement "95% the energy density..." should be "95% the specific capacity...", vs. NMC811 @ 0.1C. NFA had 140mAh/g @ C/3, 3.0V-4.5V after 100 cycles vs. Li metal, giving ~210 Wh/kg vs. NMC811’s ~260Wh/kg. This 80% reduction is okay considering we expect lower material costs!

[LiNFAO (Team 3) @li_nfao]

@joshuagallaway @NU_ChemE “95% the energy density...” should be “95% the specific capacity...”. The specific capacity is for 0.1C, NFA has 190mAh/g vs. NMC811’s 200mAh/g. However, NFA drops to ~120mAh/g at 1C. This is a concern for EV high rate requirements, but we’re optimistic for future optimizations!

@WillitsLab @NU_ChemE Great point! By removing cobalt from our process we are less dependent on it's highly volatile market as well as the highly unethical sourcing of it. The LiNFAO precursor is the product of our CSTR from feeds of our three metal sulfates and 2 hydroxide streams (ammonia and NaOH).

[LiNFAO (Team 3) @li_nfao]

@joshuagallaway @NU_ChemE Thank you so much for your question! Yes, all three of our metals, nickel, iron and aluminum are introduced to our process as sulfates. Nickel sulfate is both the most expensive and most dangerous of the three as it is a known carcinogen and must be handled with great care.
