As further improvement of the utility model, the positive pole ear surface is coated with upper tab, tab on this Positive pole ear and outside sealing are completely cut off;The negative lug surface is coated with lower tab, the lower tab by negative lug with Outside sealing isolation.
As further improvement of the utility model, the battery core body include stack and spaced setting it is some just Pole piece and some negative plates, and often separated between adjacent positive piece and negative plate by barrier film;The positive pole ear is welded in positive pole On piece, and to be drawn from one end of battery core body, the negative lug is welded on negative plate, and from the relative opposite side of battery core body Draw.
As further improvement of the utility model, the barrier film includes some membrane layers stacking and formed, some positive poles Each positive plate in piece is inserted in a membrane layer, each negative plate insertion adjacent two layers barrier film in some negative plates Between layer.
As further improvement of the utility model, the aluminum plastic film is mainly covered by aluminum plastic film on one with aluminum plastic film once Form, window is located on upper aluminum plastic film on this, and the lower window is located on lower aluminum plastic film.
The beneficial effects of the utility model are:
(1)By the way that positive pole ear is pasted on into the whole upper surface of battery core body, it is whole that negative lug is pasted on into battery core body Individual lower surface, therefore, the size of positive pole ear and negative lug are sufficiently large, it might even be possible to it is big to almost with the positive plate of battery core or Negative plate pole piece size is identical;
(2)Because positive pole ear and negative lug are drawn from the upper and lower surface of battery core respectively, therefore, battery core is in discharge process In, battery core bulk temperature is uniform, is not in superheating phenomenon, efficiently avoid the battery core electric discharge that tradition is gone out lug by one end pair When at lug the too high phenomenon of temperature, particularly, it is the most obvious for more than 80Ah battery core, effect;
(3)By coating tab on positive pole ear and negative lug respectively, and by way of sealing, ensure positive pole Between lug and negative lug, between positive pole ear and upper aluminum plastic film, between negative lug and lower aluminum plastic film respectively formed sealing The effect of isolation.
Above-mentioned is the general introduction of utility model technical scheme, below in conjunction with accompanying drawing and embodiment, to the utility model It is described further.
