At present, the resolution of mobile devices is getting higher and higher, and the battery technology of mobile devices does not evolve synchronously, resulting in worse battery life. One important aspect that consumers want product enhancements is the battery life. Now known as "egg yolk and egg shell," the new nano-particles, lithium-ion batteries may usher in a new era. The challenge of making a better battery today is to allow the electrode to better pass charging and discharging cycles. These charge / discharge cycles may cause the surface of the lithium battery electrode to peel off and deform, thereby degrading the lithium battery life. Researchers from the Massachusetts Institute of Technology and Tsinghua University have found a new way to prevent the irreversible loss of lithium while increasing battery capacity and power. The researchers created the electrodes with nanoparticles and had a solid shell. The solid "egg yolks" inside the enclosure can be resized repeatedly without affecting the enclosure. The team said this could mean significant battery improvements. This battery is mainly made of aluminum anode, the shell is made of titanium dioxide. The egg yolk material is separated from the shell and the voids allow it to expand and contract without affecting the shell. The new battery uses less expensive materials and the battery is easy to expand. There are signs that this new battery is close to commercial utility. copper fittings approved WRAS,DVGW,SABSS,UPC,NSF61,covered EN1254-1 and ASME B16.22,copper fittings,copper pipe fittings,copper plumbing fittings,copper capillary fittings,copper pressure fittings copper fittings,copper pipe fittings,copper plumbing fittings,copper capillary fittings,copper pressure fittings Taizhou Runde Company , https://www.nerausmotor.com
