Description
Technical field
The utility model relates to a kind of energy storage device, particularly relates to a kind of secondary cell.
Background technology
Lithium rechargeable battery relies on lug to be linked together by the positive/negative plate of the inside of electrical equipment and lithium rechargeable battery.Lug is divided into positive pole ear and negative lug.The both positive and negative polarity lug of traditional lithium rechargeable battery is the side being distributed in battery, as shown in Figure 1.Lug packaging area in Fig. 1 can ensure the fastness that lug encapsulates, and ensures inside battery and external environment, to guarantee that inside battery chemical reaction normally carries out.In order to ensure that lithium rechargeable battery can normally work, positive pole ear 2 can not contact with negative lug 3, otherwise has the risk of short circuit, even Fire explosion etc.So certain distance will be had between the positive pole ear 2 arranged along the direction of the width W 1 of battery core 1 and negative lug 3, simultaneously in order to ensure the feasibility of volume production operation, distance between the direction positive pole ear 2 and negative lug 3 of the width W 1 of battery core 1 is at least greater than more than 1mm, and the width W 1 that simultaneously also will meet battery core is greater than the width W 2 of positive pole ear 2 and width W 3 sum of negative lug 3.
But, along with electronic equipment is to the variation of the demand of lithium rechargeable battery, the demand of the little lithium rechargeable battery of capacity is got more and more.For such secondary cell especially lithium rechargeable battery, usually little and narrow battery core can be designed to, but for so narrow battery core, namely the width W 1 for battery core 1 is not less than the width W 2 of positive pole ear 2 and the narrow battery core of width W 3 sum of negative lug 3, when width W 1 along battery core 1 arranges positive pole ear 2 and negative lug 3, when width W 3 sum of the width W 2 that the width W 1 of battery core 1 equals positive pole ear 2 with negative lug 3, distance between the direction positive pole ear 2 and negative lug 3 of the width W 1 of battery core 1 is zero, if normally encapsulated, positive pole ear 2 can be very easily caused to contact with negative lug 3, thus very easily cause lithium rechargeable battery short circuit, when width W 3 sum of the width W 2 that the width W 1 of battery core 1 is less than positive pole ear 2 with negative lug 3, positive pole ear 2 and negative lug 3 can partly overlap, and cannot normally encapsulate like this.If encapsulation can very easily cause positive pole ear 2 to contact with negative lug 3 by force, thus very easily causes lithium rechargeable battery short circuit.
Utility model content
In view of Problems existing in background technology, the purpose of this utility model is providing a kind of secondary cell, it width of packaging electric core effectively can be not more than the narrow battery core of the width of positive pole ear and the width sum of negative lug, thus do not contact when ensureing that positive pole ear encapsulates with negative lug, the short circuit caused when avoiding secondary cell to encapsulate.
To achieve these goals, the utility model provides a kind of secondary cell, and it comprises: battery core, has anode pole piece and cathode pole piece; Positive pole ear and negative lug, be electrically connected with the anode pole piece of battery core and cathode pole piece respectively; And encapsulating shell, for packaging electric core there is positive pole ear packaging area and negative lug packaging area; Wherein, the width of battery core is not more than the width of positive pole ear and the width sum of negative lug; Positive pole ear and negative lug are arranged faced by the direction vertical with the width of battery core; Positive pole ear packaging area and negative lug packaging area are arranged faced by the direction vertical with the width of battery core.
The beneficial effects of the utility model are as follows:
According in secondary cell of the present utility model, when the width of battery core is not more than the width sum of the width of positive pole ear and negative lug, due to positive pole ear and negative lug along the direction vertical with the width of battery core in the face of to arrange and positive pole ear packaging area and negative lug packaging area are arranged faced by the direction vertical with the width of battery core, thus the width of packaging electric core is not more than the narrow battery core of the width of positive pole ear and the width sum of negative lug effectively, thus do not contact when ensureing that positive pole ear encapsulates with negative lug, avoid the secondary cell short circuit caused when encapsulating.
