According to new research released this week, future batteries may have twice or even three times the power capacity of current standard lithium-ion batteries. For ordinary users, this means that the smartphone can last for several days. More importantly, it will not sacrifice the service life of the battery, but will further reduce the size. < / P > < p > the team from the University of Texas at Austin found that several metal oxides have physical energy storage capacity beyond the theoretical limit. Currently, the standard method of battery energy storage is to allow lithium ions to move through the material, or convert the crystal structure of the material. With these metal oxides, energy can be stored not only in the transition metal oxides, but also on the surface of reduced metal nanoparticles formed by low potential discharge of transition metal oxides LIBS. The method pointed out by Yu is in-situ magnetic measurement. This is the most basic real-time magnetic monitoring system. Through this system, the magnetic changes in the electronic structure of the material are monitored, which helps to quantify the charge capacity of the material. The results show that the charge capacity on the surface of some materials is the main source of battery capacity exceeding the standard. This additional surface capacitance exists in the systems of Fe ₃ o ₄, NiO, FEF Ψ and Fe Ψ n. Chinese version of K-car: reading a10e design drawing exposure
