The Next Big Li-Ion BATTERY PERFORMANCE Breakthrough

Published 2021-07-13
There are a number of different battery technologies that claim to be the next BIG battery breakthrough, and many of them have a lot of promise. However, no matter what future battery tech looks like (whether that be solid state, semi-solid state of more conventional batteries with liquid electrolytes), I personally believe SILICON will play an important role in improving our batteries. In this video I discuss why.

    I'm also a big fan of aluminum ion batteries :)
    They seem like they have alot of potential
  • I'd check out SilLion, which was a startup company out of CU Boulder that was acquired by Tesla. As far as I can tell, their approach is also to coat Si anode particles with organic films, maybe including functionalization of Si surfaces using organic reactions.

    I'm not so sure about the "plastic deformation" of the coating mechanism described in the patent. If the coating does not contract and you create void space between the film and the Si particle, Li+ will not be able to diffuse to the Si, reducing power/capacity. Also, the coating should do more than just prevent HF from the electrolyte contacting the Si. It also needs to hold the Si particle together so that you maintain Li+ diffusion pathways or otherwise, you also have the problem of lowering power because Li+ transport to the anode is limited.

    Great video and content, thanks for focusing on Silicon. I agree this is the next big step
  • clavo
    Wow! Great patent review. Most plastics I've known eventually fatigue. Did this patent address the potential for fatiguing? Also, the 0 to 100 replacement you spoke of (I'm assuming you meant 0-100 percent replacement of graphite) makes this technology subject to marketing incremental sales strategies that eventually fatigue, the people, that have to put up with that. Is that correct? The post boomer generations may remember the 286 computers that were replaced with the 386 then 486, etc.

    First of all, thanks for the video and the links.
    The historical problem with Si as an anode is expansion/contraction which eventually tears the structure apart. Sounds like the patent provides for a shell such that the expansion/contraction takes place inside the shell and doesn't compromise the battery structure, but wouldn't the expansion/contraction still occur (inside the shell) and eventually destroy the anode? I have my doubts that this will work on a battery large enough to power an EV.
  • Tesla recognised years ago that solid state won’t turn up in volume till toward the end of this decade, but that Lion still had room to develop. Furthermore, the world can’t wait for a perfect solution…. We need, affordable, usable and reliable batteries today if we are to “speed the transition to an electric future”. Other OEMs seem to be pinning their hopes on the solid state chimera to “save them and outflank Tesla”. This strategy is not working and my pick is that it won’t work…

    👍video. BEV technology is just at the first innings of S-innovation curve, while cost is following Wright's law down, as Cathie told us many times. I look forward to the day when batteries will have a blend for low cost , one for super long life, one for extreme power density, fast charge, so on... Wouldn't it be great if one can order the customized performance blend🔋to fit his goals perfectly? 🥰
  • lowrads
    I wonder if the strain energy of induced crystal lattice defect voids could have an effect on the expansion properties of the anode mineral.
  • Mr G.
    Enovix seems to be producing some nice batteries. 100% 3d Silicon Anode

    Porsche is setting up a new factory for battery cells, called Cellforce, in Tübingen, Germany. The plant will be run as a subsidiary of Porsche in a joint venture with Customcells and will develop cells that use silicon as opposed to graphite for the anode material.

    we visited the StarShip last Oct & loved it. I've bought some tsla dips & I've ordered the tri motor cybertruck fsd last 2019 April tri motor fsd cybertruck and I can't wait for it 🙌 and I may buy the S Plaid as well if all goes well..I got lots of solar to charge them
  • Keen Heat
    hmm 300% expansion ? depend on how fast the charge and discharge rate, I wonder if you can use it as a robot actuator ? since currently eletric robot actuator type either falls into group of high torque/kg but low expansion strain, or high strain ratio but very low torque/kg group. If the silicon can be charge and discharge very rapidly, this lithium silicon battery might have an alternative use as a robot actuator. With benefit of high torque/kg and high expansion strain ratio as well. Another thing, silicon expand when charged, so does the reverse happen, I wonder if you squeeze silicon with high pressure, does it produce electricity in return ?

    Great video thanks for the information!

    If a battery is cheap enough I don't care as much how many cycles I get from it. If a battery lasts for more cycles I care less about how much it costs up front. If a battery has a higher energy density then a shorter cycle life is more acceptable. It's about $/(kwh*cycles) or $ / total energy used through the life of the battery in that application.
  • after listening to the guy from quantumscape in the interview with munro, i have a lot of trust that we have something good in reality
  • chung lee
    the polymer coating can be done by a CVD process, to achieve “conformal coating” of Si nano particle, preferably by a fluorinated polymer-(CF2-C6H4 -CF2-)
  • Dave M
    Exciting times ahead especially with the 350kw superchargers being rolled out. It's frustrating to plug your EV into any fast charger only to see charge rate achieved is well below the capacity of the charger.
  • Daryl Foster
    Charging speed will eventually decline to around 10 minutes, which is more than adequate compared to a gas fill up. Anything below 10 minutes is a bonus.
  • I think, that the future of the battery, is in the merge of condensator and battery...
