New research led by an electrical engineer at the University of California, San Diego is aimed at improving lithium-ion batteries through possible new electrode architectures with precise nano-scale designs. The researchers created nanowires that block diffusion of lithium (Li) across their silicon surface and promote layer-by-layer axial lithiation of the nanowire’s germanium core.
Laptops could work longer and electric cars could drive farther if it were possible to further increase the capacity of their lithium-ion batteries.
Stanford University scientists have dramatically improved the performance of lithium-ion batteries by creating novel electrodes made of silicon and conducting polymer hydrogel, a spongy material similar to that used in contact lenses and other household products.
Sometimes good things come in small packages. And sometimes those things are the most powerful batteries on the planet. Researchers at the University of Illinois at Urbana-Champaign have developed a tiny lithium-ion microbattery that leaves larger supercapacitors in the dust.
Scientists at Rice University have managed to design a lithium-ion battery that can be painted on virtually any surface.
Researchers from Northwestern University are working on developing a super-battery that can keep a cellphone charged for a week and be recharged in just 15 minutes.
