This Insane Liquid Battery Can Instantly Recharge

imagine you were running low on battery in an electric car but instead of having to plug in to recharge and wait for the battery to refill you could instead fill up at a pump in a matter of minutes with an electrically charged fluid much like you would refill fuel for a combustion engine car in this video we'll see how this is possible and see what it could mean for Electric Mobility by replacing the need of lithium-ion battery packs to understand that this breakthrough liquid battery it is first useful to understand the two technologies that it is based on the first of these is the standard lithium-ion battery commonly found in consumer electronics and electric vehicles and the second is the redox flow battery which stores the energy in the liquid electrolytes and is being used more and more in Grid scale energy storage Lithium-ion batteries consist of a cathode an anode and a separator which are all placed in an electrolyte fluid when charging electrons move from the cathode to the anode through an electrical circuit and lithium ions move from the cathode into the anode material storing energy when discharging the process is reversed releasing stored energy to power devices or Vehicles something important to note here is the reason Lithium-ion batteries can store so much energy is because of the specially selected cat method and anode materials on the other hand we have redox flow batteries such as the Vanadium redox flow battery which consists of two tanks containing liquid electrolyte Solutions the electrolyte fluids also serve as the anode and cathode because they have Vanadium dissolved within them this idea of a flow battery is the foundation of the new liquid battery breakthrough however it has one problem that ideas from the Lithium-ion batteries from before can help solve but as we delve further into the world of electric vehicles it's important to remember that our online privacy and security need just as much attention which is

they can't be used in electric vehicles is their low energy density for comparison a Vanadium flow battery stores about one tenth of the energy of a Lithium-Ion battery of a similar size and weight thankfully the Breakthrough from a company called influor Energy which is a spin out from The Illinois Institute of Technology can change that remember I said the reason conventional Lithium-ion batteries can store so much energy is because of the specially selected cathode and anode materials well the reason Vanadium redox flow batteries are poor at storing energy is because it isn't possible to dissolve enough Vanadium into the electrolyte fluid which is important as Vanadium is the active material that stores the energy this is why influa energy is instead suspending highly energy dense materials as nanoparticles in the electrolyte fluid with their scientific papers stating this can increase the energy density by 30 times this means their Nano fluid flow batteries or even more energy dense than current Lithium-ion batteries and can benefit from extremely fast recharging or should I say refilling so let's look at this breakthrough Energy System in some more detail the idea of suspending electrode particles inside the electrolytes of a redox flow battery has been explored before but a major issue has been that it makes the electrolyte too thick insular energy say they have solved this by using nanoparticles which have modified surfaces to prevent the particles collecting together or Sinking to the bottom because the active materials don't have to dissolve much more energy dense materials like those used in current Lithium-ion batteries can be used if we look at the analyte and catalyte fluids that store the energy we can see they are roughly the viscosity of engine oil another benefit of this is that the electrolyte fluid is also non-flammable potentially making it safer in the event of a spillage though I would be interested to see what happens if the analyte and catholite were to be mixed as one of their Publications with NASA States it would result in thermal reactions in terms of operation the nanoparticle flow battery is similar to the Vanadium flow battery we saw earlier except the electrons and ions are exchanged between the highly energy dense particles suspended within the electrolytes once the electrons have flowed through the required system the discharged electrolyte is stored in the discharge tank say you wanted to recharge or refill your nanoparticle battery you are left with two options firstly you could just plug it into an electricity source and recharge it like you would a conventional electric vehicle or you could pump out the discharged electrolyte fluids and put in charged ones using the four nozzle pump designed by influent energy this would also then enable refilling stations to slowly recharge the electrolyte fluid you just emptied out using intermittent renewable energy sources like wind and solar now let's see what they've achieved towards this big Vision influte energy has been working with NASA and DARPA among others and the key prototype Milestones appear to be their gen 1 and Gen 2 Battery Systems judging by their published work and messages I've had with their CEO it seems like the Gen 1 system requirements have been achieved which see a 23 percent increase in volumetric energy density over conventional Lithium-ion batteries I have also been informed that they developed a drop-in battery system for an electric utility vehicle that operated back in June of 2022 though publicly available details for this are yet to be released a very small scale demonstrator vehicle has been shown driving around their lab though so I'm excited to see some footage of this in full-scale vehicles the Gen 2 Nano Electro fuel battery prototype is set to be completed at the end of 2023 and Promises to deliver energy densities four to five times higher than conventional lithium-ion battery systems the Gen 2 battery system also promises to reduce the cost of energy storage to below 90 per kilowatt hour compared to a hundred and forty dollars per kilowatt hour for conventional lithium ion battery systems and the Gen 1 System apparently this will be achieved by utilizing an air cathode which is a concept Tesla has been looking into for a number of years now one key challenge for the team at influent energy is achieving High efficiencies this is because there are some additional losses from using the pumps to move the electrolyte fluids therefore the best way to improve this is to use highly efficient pumps and to keep the viscosity of the fluid relatively low while still keeping High nanoparticle densities clearly the future applications for this system could be huge because of the high energy densities and Rapid refilling times it would be appealing to passenger car vehicles long-haul Trucking and at large utility vehicles but excitingly it may also increase the feasibility of longer distance electrical powered flight as you're still watching please subscribe to the channel as I think you'll like some of the other videos I make like this one onto
