摘要:
The invention relates to a battery cell (101; 101'; 101"; 101"'), comprising a first electrode foil (102) and a second electrode foil (103), which are rolled up together with an interposed separator to form a roll (104; 104"'), a first (105; 105"; 105"') and a second terminal connector (106; 106"; 106"') for connecting the battery cell (101; 101'; 101"; 101'") to external circuitry, a first connecting element (107; 107'; 107"'), which electrically connects the first terminal connector (105; 105"; 105"') to the first electrode foil (102), and a second connecting element (108; 108'; 108"'), which electrically connects the second terminal connector (106; 106"; 106"') to the second electrode foil (103). According to the invention, the two connecting elements (105, 107; 105", 107"; 105"', 107"') make contact with the respective electrode foil (102; 103) on a first end face (110; 110') of the roll.
摘要:
The present invention relates to a high output and large capacity secondary battery module that can be charged and discharged by a plurality of unit cells electrically connected one another, and more particularly, to a secondary battery module that prevents volume expansion, damage, and the formation of cracks in the unit cells, and the cooling efficiency of the unit cells of which is improved by means of including a heat-dissipating member on each of the unit cells that are stacked in series.
摘要:
A rechargeable battery includes a case (26), an electrode assembly (10) in the case (26), at least one terminal portion (30) disposed at least partially inside the case (26), at least one current collecting member (50) electrically connecting the electrode assembly (10) and the terminal portion (30), the current collecting member (50) including a terminal coupling portion (52), and at least one insulation member (60) in the case (26). The insulation member (60) includes a current collecting member coupling portion (61) into which the terminal coupling portion (52) extends. The current collecting member coupling portion (61) supports at least a portion of the terminal coupling portion (52).
摘要:
Disclosed is a rechargeable battery including an electrode assembly in which positive and negative electrodes and a separator may be exactly arranged. The rechargeable battery includes an electrode assembly including a positive electrode, a negative electrode, and a separator, a case housing the electrode assembly, a positive terminal being electrically connected with the positive electrode and protruded outside the case, and a negative terminal being electrically connected with the negative electrode and protruded outside the case. The positive and negative electrodes respectively include a plurality of positive uncoated regions and a plurality of negative uncoated regions extended out of the separator and laminated along one direction. The positive and negative uncoated regions include at least two openings respectively along the laminating direction.

摘要:
A recombinant lead-acid battery comprising a plurality of lead-acid cells in a case (14) including apertured partitions (22) defining space for vapor migration among cells and comprising a catalyst unit (26) communicating with said vapor migration space (24) and enhancing recombination of hydrogen and oxygen.
摘要:
A sealed lead-acid cell is provided with an internal cell restraint (36) which contacts the interior surface of the cell cover (14) and is positioned between the positive plates of the cell and the cover (14), the internal cell restraint (36) cooperating with an external cell restraint (50), such as a plastics coated metal face plate, to direct positive plate growth which occurs in service away from the cover (14). The cell construction disclosed allows plastic-to-plastic seals to be used between the terminal ports (18, 20) and the cover (14), and allows cells of capacities of up to 2,000 Ampere Hours or more to be provided.
