I think solid state batteries are likely a better option at this point. There are several companies already building test production facilities or producing test batteries. SSB's are lighter and have a higher w/l energy density than even SOG batteries.

[@geneard639]

between 5 to 10 years if it delivers on expectations. I am more interested in its capacity for thermal runaway and catastrophic events. I've seen an 8 pound lithium battery for a Marine Radio blow....well.... I saw the Sargent in charge of the Battery Locker fly through the door, taking the door, and about 50 feet across the field where the Battery Locker was at. Made me happy to be in charge of the Aircraft NiCad Battery Locker. Thermal Run Away? easy to deal with. Lead Acid (not me, AS2 had that one) never had an issue. 20 years working Aircraft only saw one NiCad Battery go in thermal runaway.... saw a few Lithium Batteries pop...but, Navy gotta expect that.

Genuine question: When people say things like, “..even at just 1 atom thick, it’s 200x stronger than steel.” Is that comparison with a hypothetical 1 atom thick sheet of steel?

5:37 Little clarification - SEI layers form on battery anodes due to decomposition of the electrolyte or additives therein. This is true for both graphite and silicon anodes. The formation of SEI is mostly considered to be beneficial because it creates a stable, electrically insulating layer which allows Li+ ions to pass through, but prevents the electrolyte decomposing further. It does increase resistance, but the battery wouldn't last more than a handful of cycles without it.

The fact that silicone and graphine can't be embargoed or blockaded during a war is a huge part of this logic. In the short term, and possibly medium term depending on who wins today's election, our dependance on Chinese rare earth metals in a potential war against China is going to suck for the military. That's why it's very controversial when defense directors get caught importing components, because their almost always importing from China.

We have more than an adequate lithium deposits here in the US to keep the US supplied with Li for a couple hundred years, but it is near impossible to mine it with the Feds not allowing it.

@@Tempestan not exploiting US oil and gas empowers Russia and Middle Eastern theocracies. Not exploiting US lithium deposits empowers China. As far as environmentalists or climate change people are concerned, US with stricter environment regulations should be able to do it cleaner than China and Russia pound for pound, and climate is a global problem. There are 2 active wars we are paying for, one of them enabled by EU dependence on Russia's oil and gas.

@@thomasostrander4835 we already had achieved net exporter status in 2017 and 2019 and the momentum was strong.

More importantly battery powered tanks are quieter than the diesel counterparts. They can practically go stealth without making much noise. I can see one of the reasons why the military is looking into this.

[@heinzamatic]

@@Darkk6969 With thermal imaging being standard on weapon platforms and with today's increased stand off distances, noise isn't nearly as important as heat signature. With a lack of engine and exhaust, heat signatures would be drastically reduced.

@Darkk6969 yup, i heard one of the reasons the US went with a turbine engine for the Abrams instead of diesel, the high winding noise from the turbin is very loud up close but dissipates quickly over a long distance while the low humm of a diesel engine travels further. Obviously with battery, the loudest thing will be the cooling fans.

Slight complaint: at 6:56 you claim that more lanes help traffic, while this isn't the case in real world car infrastructure. It's a common misconception but it's important to recognize!

[@kevinamery5922]

More lanes do help move an equivalent number of vehicles faster -- so 5 lanes will move 100,000 cars more quickly than 4 lanes. The issue in traffic is that more lanes also attract more traffic, so when you increase from 4 lanes to 5 you could still move 100,000 cars more quickly, but now you've got 150,000 cars so you end up losing. Fortunately, electrons in a battery don't work that way...

[@TheSpearkan]

The statement of graphene being expensive to manufacture is actually only half the story. I remember actually speaking with some scientists experienced in graphene and a common thread I found is that they all make their graphene on site before use. Not because they can't buy it from a manufacturer or that it's too expensive, but because the physical, thermal or chemical properties do not match what they wanted or it turned out that the product was actually just really fluffy graphite. The truth is, there is no quality control process for graphene nor a way to fully determine the size and thickness of a graphene sheet without an overexpensive microscope that can see at the atomic level. It is also worth noting that this criticism focuses on graphene made from graphite or materials with large compositions or "top down" methods. Bottom up methods that make graphene from carbon containing gases like methane or acetylene use really expensive CVD machines that absolutely fall under the videos criticisms. I imagine Nanograf are making all their graphene on site before battery production.
