Crystal alignment of a LiFePO4 cathode material for lithium ion batteries using its magnetic properties

摘要: We suggest a way to control the crystal orientation of LiFePO4 using magnetic field obtain an advantageous structure for lithium ion conduction. examined properties such as magnetism and susceptibility, which are closely related rotation in external field, considered how use these desired orientation; thus, we successfully fabricated crystal-aligned LiFePO4, b-axis was highly aligned perpendicular surface current collector. Considering low conductivity inherently originated from its one-dimensional path diffusion, potentially facilitates favorable transport kinetics ions during charge/discharge process batteries. The should afford lower electrode polarization than pristine thus former consistently exhibited higher reversible capacity latter.
