Titania-coated aluminium particles for high-capacity anode

摘要

An anode comprising aluminium nanoparticles covered with a solid shell of titanium dioxide for a lithium-ion (Li-ion) battery has been developed by researchers in the USA and China. In a paper in Nature Communications, the Massachusetts Institute of Technology (MIT)-Tsinghua University team says that the aluminium nanoparticle can expand and contract repeatedly without affecting the shell, which could enable a dramatic boost in a Li-ion battery's capacity and power.
