摘要:
A secondary battery includes an electrode unit having a first electrode plate, a second electrode plate, a separator interposed therebetween, and first and second electrode tabs respectively extending from the first and second electrode plates, a can adapted to accommodate the electrode unit and an electrolytic solution, and a cap plate adapted to seal the can and having an electrolytic solution inlet, wherein the electrolytic solution inlet has an area on one surface of the cap plate different from that on another surface of the cap plate.
摘要:
A lithium secondary battery includes a can made of a conductive metal. The can houses an electrode unit having positive and negative electrode plates with a separator interposed therebetween with an electrolytic solution. An upper opening of the can is sealed by a cap assembly. A bottom plate is welded to an outer bottom surface of the can, and a lead plate having a first end welded to the outer bottom surface of the can and a second end connected to a safety device so that the can is electrically connected to the safety device.

An electrode unit and a secondary battery having the electrode unit include a first electrode plate having a first electrode uncoated portion on at least one side of a first electrode collector coated with at least a first electrode active material, a second electrode plate having a second electrode uncoated portion on at least one side of a second electrode collector coated with at least a second electrode active material, and a separator interposed between the first electrode plate and the second electrode plate, wherein an insulating separator having at least two folds is located between the first electrode uncoated portion and the second electrode uncoated portion.
摘要:
A secondary battery includes an electrode assembly with a positive electrode plate, a negative electrode plate, and a separator disposed between the positive and the negative electrode plates. A can in which the electrode assembly is mounted has an opening portion. A cap assembly is mounted at the opening portion of the can to seal the can. The cap assembly has a cap plate fitted to the opening portion of the can, and the hardness of the can is greater than the hardness of the cap plate.

摘要:
A Braun tube having an antibacterial coating film, which is manufactured by the steps of dispersing titanium dioxide (TiO2) in alcohol to prepare a dispersion. Then, the dispersion is coated on a Braun tube, and a thermal treatment is then performed. By a photocatalytic reaction of the titanium dioxide contained in the antibacterial coating film, oxygen (O2) and water (H2O) in the air are decomposed into superoxides (O2−) and hydroxy radicals (OH·), which destroy bacteria and mold around the Braun tube and remove bad odor.
