It's surprising how all breakthroughs are precisely, always, 10 times better. Let's wait until a HN battery expert tell us

Maybe nobody does research on tech that isn't at least 10 times better than the stuff we already have?

  A 2x increase for battery storage would be game changing for a wide variety of use cases. Electric vehicles, industrial applications...

    Battery tech is improving at around 10% a year. Lithium Battery density has tippled in the last 10 years people on hacker news like to comment on how new battery technology has not done anything but since those comments started a decade ago battery density has trippled. https://cleantechnica.com/2020/02/19/bloombergnef-lithium-ion-battery-cell-densities-have-almost-tripled-since-2010/ https://cleantechnica.com/2020/02/19/bloombergnef-lithium-io...

      If it's improving at a rate of 10% per year, a 2x would take 4-5 years to achieve so a 2X is really a good improvement. I wonder where we'd be right now had we not gone the ICE route.

  Reality is most new technologies need to be 10 times better to get investment. Otherwise it is generally assumed that by the time new technology gets into production the older tech will still have cost advantage. This is the main reason why we need government investments for unprofitable research.

  Or when it's only 5x better, they quietly continue tinkering around, and only when it's 10x better do they announce their results and try to get funding.

"Its multifunctional performance is ten times higher than previous structural battery prototypes." The problem is we don't really know what multifunctional performance means or how it's defined, but maybe this is a common metric in battery technology? edit: I skimmed the actual paper linked in the article and it doesn't mention a 10x improvement. "Structural battery composite materials, exploiting multifunctional constituents, have been realized and demonstrate an energy density of 24 Wh kg−1 and an elastic modulus of 25 GPa. Their combined electrochemical and mechanical properties outperform all previous structural battery materials reported in the literature. "
