Recently, the Massachusetts Institute of Technology has developed a new battery technology called of "yolk" and "eggshell".
The researchers developed a new "egg" battery, use an electrode made of solid nanoparticles "shell" package, which has an "egg yolk" that can repeatedly change the size of the battery, without damaging the shell. The researchers said that the invention can significantly improve battery life, while providing increased battery capacity and power. It is reported that this new "egg" battery anodes using a titanium dioxide "shell" and aluminum "yolk." In other words, this battery will be different from the current lithium-ion batteries, they expand and contract without reducing battery power. With the addition of titanium dioxide and aluminum materials, under normal charge, the battery capacity will be three times the normal battery. Because there is no "expansion - contraction" performance degradation, these batteries can be fully charged six minutes.
