A housing for a waterproof electronic device includes a case with a front opening adapted to receive circuit components therein, and a front cover attached to the case so as to cover the case. The front cover is fitted onto a periphery of the front opening of the case so as to prevent rainwater from entering from outside. The case has an arched top plate, and includes, at a front of the case, a fitting stage, to which the front cover is fitted, so as to protrude from the case along the periphery of the front opening. The fitting stage has right and left side wall sections and at least one drain groove provided along peripheral surfaces of the top plate and both of the right and left side wall sections so that lower ends of the drain groove open downward at a bottom of the case.

A first paste for a first electrode layer and a second paste for a second electrode layer are printed on a fired solid electrolyte by screen printing, etc. to form electrode patterns for forming the first electrode layer and the second electrode layer. The first and second pastes can be prepared by dissolving a binder in an organic solvent, adding an appropriate amount of the obtained solution to powders of an electrode active substance material and a solid electrolyte material, and kneading the resultant mixture. The first and second pastes are applied to the fired solid electrolyte to form a cell precursor, the cell precursor is placed in a hot press mold subjected to a thermal treatment while pressing from above by a punch, whereby the first and second electrode layer are formed from the first and second pastes.

A lithium secondary cell includes an internal electrode body having a positive electrode plate and a negative electrode plate wound and laminated around an external peripheral wall of a hollow cylindrical winding core. The inside of the internal electrode body is impregnated with a nonaqueous electrolyte solution. A cylindrical cell case houses the internal electrode body and has open ends sealed with plate member electrode caps. An external terminal member protrudes onto the surface of the electrode caps to lead current to the outside of the cell case, and an internal terminal member connects with the internal electrode body to take current from the internal electrode body. An elastic body and at least two of the plate member, the external terminal member and the internal terminal member are joined together for construction. An assembly of lithium secondary cells is also disclosed.

A lithium secondary battery comprises an internal electrode body formed by winding a positive electrode and a negative electrode on an outer peripheral wall of a hollow winding core, nonaqueous electrolyte solution contained in the case, a cylindrical battery case containing this internal electrode body inside, at least one electrode cap sealing the internal electrode body, and at least one pressure release hole in a position corresponding with the center axis of the winding core.
摘要:
A lithium secondary battery includes an electrode body obtained by winding or laminating a positive electrode and a negative electrode via a separator, and a non-aqueous electrolytic solution containing a lithium compound as the electrolyte. The non-aqueous electrolytic solution contains water (H2O) and hydrofluoric acid (HF) in a total concentration of 10,000 ppm or less. Owing to the restriction of the total concentration of water and hydrofluoric acid contained in the non-aqueous electrolytic solution, the lithium secondary battery can suppress the deterioration of battery properties caused by the water and hydrofluoric acid and has excellent cycle property and reliability.
