[ad_1] According to IBM, the new design could outperform current lithium-ion batteries in cost, charging time (less than five minutes to reach an 80 percent charge), power density and energy efficiency. The battery is also less flammable, and it could be used in aircraft and smart energy grids, as well as electric cars and trucks. […]

[ad_1] The team described the “magnetically steerable, hydrogel-coated robotic thread” in a paper published in Science Robotics. The core of the thread is made from nickel-titanium alloy, which is both bendy and springy. It’s coated with a rubbery paste, or ink, which is embedded with magnetic particles. That’s then covered with a hydrogel, which makes […]
