American scientists have developed a new button photocell
Recently, American scientists have developed a new method to create a button battery, which is fueled by butane, and its running time is four times that of a lithium-ion battery of the same weight. When the power is exhausted, only a small amount of new fuel is added. The battery can be charged immediately. They also created another block made of a radioactive isotope
Recently, American scientists have developed a new method to create a button battery, which is fueled by butane, and its running time is four times that of a lithium-ion battery of the same weight. When the power is exhausted, only a small amount of new fuel is added. The battery can be charged immediately. They also created another battery powered by the decay of a radioactive isotope, which can continue to generate electricity for 30 years without refueling or maintenance, and is expected to be an ideal power source for equipment on long-duration space missions.
Ian Selanowitz, an engineer at the Institute of Nanotechnology (ISN) at the Massachusetts Institute of Technology, said that tungsten is an important raw material for new batteries, and billions of nanometer-sized pits have been etched on the surface of tungsten. When tungsten absorbs heat, whether it comes from the sun, hydrocarbon fuel, decaying radioactive isotopes, or other heat sources, it glows brightly, and the emission spectrum is constantly changing because each pit acts like a resonator, emitting a specific wavelength of light waves.
According to data provided by the Information Management Center of the U.S. Department of Energy, 92% of the energy used today has to go through the process of converting thermal energy into mechanical energy and then into electrical energy. But existing mechanical energy systems are relatively inefficient and cannot be scaled down for use in sensors, smartphones or medical monitoring equipment.
