• •Daqus Energy has been quietly operating for the past couple years, refining a compound known as TAQ that promises to be cheaper and lighter than competing battery materials.
• •The material Daqus has discovered, bis-tetraaminobenzoquinone or TAQ for short, isn’t made using expensive critical minerals like nickel or cobalt. Instead, it’s made entirely of widely available carbon-based compounds.
• •Daqus has been producing coin cells in its lab space in Massachusetts, and its internal tests have shown TAQ to be durable. TAQ-based batteries can be charged and discharged 2,000 times and maintain at least 80% of its original capacity, and they’re stable at high temperatures. Those small batteries also charge at a rate that, when extrapolated to EVs, would enable six minute fast charging

Daqus Energy has been quietly operating for the past couple years, refining a compound known as TAQ that promises to be cheaper and lighter than competing battery materials. The material is made entirely of widely available carbon-based compounds and can be produced using existing equipment. Daqus has been producing coin cells in its lab space in Massachusetts, and its internal tests have shown TAQ to be durable. TAQ-based batteries can be charged and discharged 2,000 times and maintain at least 80% of its original capacity, and they're stable at high temperatures.
