Title: Manufacture of electrode for battery by squeeze molding and its electrode
Inventor: OHASHI YOSHIHISA
IPC: H01M4/62
Filed: 1998-10-27
Abstract: PROBLEM TO BE SOLVED: To increase filling density and enhance capacity by preparing slurry containing active material powder, water, and a binder, by pressing the slurry through a filter material to squeeze to remove water and the binder, and by conducting squeeze molding to recover an electrode. SOLUTION: Preferably, slurry contains an electrolyte, the slurry prepared with active material powder, water, and a binder is squeeze-molded to prepare an electrode. With increase in filling ratio, gaps between active material particles are decreased, penetration of the electrolyte into the electrode is made difficult, and increase in electrode capacity is also made difficult. The electrode active material is prepared in slurry, the slurry is pressed through a filter material as squeeze molding for squeeze-removing a liquid component, and by the squeeze molding, liquid component removed paths are left as pores, and many continuous pores are effectively formed by this wet molding process. By conducting pressure-filtering to the slurry, since the electrolyte is impregnated in the pores of the electrode recovered after squeeze molding, the capacity of a battery is increased.
