meretricious , lighter , and denser : The trifecta defines an idealistic battery . No one has machinate a perfect cadre quite yet , but one stealthy inauguration consider it has found a new stuff that lick at least two of those challenge .
Daqus Energyhas been quietly operating for the past four months , fine-tune a chemical compound known as TAQ that promise to be punk and lighter than competing barrage fire textile .
“ We have not run into a system of measurement at which TAQ does ill compared with the officeholder , ” Harish Banda , atomic number 27 - founder and CEO of Daqus , told TechCrunch . The ship’s company was spun out of MIT , where research into the textile was funded in part through apartnership with Lamborghini .
There are a few caveats , which Banda freely propose : The caller is still scale production of TAQ , and it has only just begin work on the type of cell that could send packing into an EV . Plus , manypromising bombardment materialshave died on the path to commercialization .
But the upper side is unassailable enough that Daqus is emerging from stealth with a $ 6 million seed round led by Morningside with participation from nameless individual investors .
Daqus ’s stuff supercede the cathode in a Li - ion electric battery . In a typical cell , the cathode is made of atomic number 28 - manganese - cobalt ( NMC ) or iron - phosphate ( well known as LFP ) . NMC cells are more expensive but offer greater energy compactness and foresighted range in electric vehicles . LFP cells are tacky but heavier .
U.S. and European auto manufacturer have favour NMC for their EVs , but they ’ve begun to change over to LFP to cut price . job is , the vast absolute majority of LFP cathode material are made in China , making them a nonstarter for U.S.-made EVs that need to characterise for taxation credit .

The cloth Daqus is working with , bismuth - tetraaminobenzoquinone , or TAQ for shortsighted , is n’t made using expensive vital mineral like Ni or Co . alternatively , it ’s made entirely of widely available carbon - found compound .
For the first step in the manufacturing process , the two corpuscle the company uses are already used to make dyes and fertilizers . “ They are absolutely dirt tawdry , ” Banda say , noting that the company buy small pile at $ 1 per kilogram . “ So you’re able to only think what that means when you corrupt a ton of it . ”
What ’s more , the mental process used to synthesize a TAQ cathode utilize vastly less vigour . get to the stuff only requires heat it to 120 ° C , some 700 ° C to 800 ° C low than LFP or NMC cathodes , Banda said .
On themanufacturing argument , TAQ can be deposit using subsist equipment . But there ’s another chance to cut cost : existing anode manufacturing equipment can also work with TAQ . That would reserve battery makers to employ water system as a solvent instead of NMP , a toxic solvent that need to be captured and recycled .
Altogether , TAQ ’s qualities have provide Banda tone surefooted that the stuff can undercut the cheapest lithium - ion barrage fire on the market . “ If somebody is say that LFP barrage fire are at $ 50 per kilowatt hour , we would be cheaper than that for sure , ” Banda said . “ Exactly how much needs to be figured out . ”
Daqus has been producing coin cells in its science laboratory space in Massachusetts , and its internal tests have shown TAQ to be long-lived . TAQ - based batteries can be charge and discharged 2,000 meter and preserve at least 80 % of its original content , and they ’re unchanging at high temperatures . Those small batteries also charge at a rate that , when extrapolated to EVs , would enable six - minute fast charging .
If there ’s a caution , it ’s that TAQ cathodes take up more place than NMC , though they ’re private-enterprise with LFP . Still , he channelize out that because the material is light , electron volt designed around it could also be made light and would need fewer batteries overall . That could give TAQ - power EVs enough reach to compete with NMC while being meretricious and lighter .
Sports railway car might realize the benefits sooner . Weight has been one of the freehanded penalties of electrification : It ’s fabulously easy to make an EV that ’s lightning promptly in a unbent parentage , but have one that handles well on a race track ? That ’s proven to be harder . A lightweight , tight - charge battery pack could go a longsighted way toward making electrical sports cars finger particular and all cars more efficient .
“ Lots of car company in the world are prove to make electric cars , ” Banda said . “ What ’s the difference between a Rolls - Royce versus a Tesla ? Sure you have better seats , but in term of the nub of the car , it used to be the railway locomotive . Now it seems to be the battery . ”
