Latest Patents

Zenichiro Ito holds a patent for a non-aqueous electrolyte secondary cell. This invention comprises a positive electrode sheet made from lithium-containing metal oxide, a negative electrode sheet utilizing graphitic particles, a separator, and a non-aqueous electrolyte. The negative electrode sheet is produced by mixing major graphitic particles with a binder to create a paste, which is then coated on both sides of a collector. The coating layer has a porosity of 25% to 40%, and the graphitic particles have an average particle size ranging from 3 µm to 25 µm. These particles are produced through a meticulous process involving heat treatment of pitch in a molten state, resulting in carbonaceous mesophase particles that undergo carbonization and graphitization at high temperatures. The final product exhibits specific characteristics, including a lattice plane spacing (d002) of 3.36 Å to 3.39 Å and a crystal size in the direction of the C axis (Lc) of 200 Å to 650 Å.
