Abstract
An improved polymer lithium ion battery structure relates to the improvement of a polymer lithium ion battery structure, which comprises a conventional packing film, a positive plate, a negative plate, an insulation separation film, an electrode ear and an electrolyte, and is characterized in that a positive and a negative electrode ears of a battery core are embedded inside a battery core, a combinational protective circuit board is connected with the positive and the negative electrode ears, and a contact of the protective circuit board faces outwards and is connected with an electric appliance. The improved polymer lithium ion battery structure is applicable to different batteries with different sizes and can overcome the weakness that the specific energy of the battery is low since the space application is inadequate. At the same time, with a plurality of electrode ears, the problem of the large-current charging and discharging of the battery can be effectively solved, so that within the limited space range, the volume of the battery core can be increased by reducing the occupied space of the protective circuit board, and the capacity of the battery can be improved, so as to improve the specific capacity of the battery. The above technical proposal is applied to the design and development of the polymer/soft packed battery and the improved polymer lithium ion battery has simple structure and is simple, convenient and easy to operate.
Description
Technical field

It also can be more than one positive pole ear that described battery can be provided with one, and one also can be more than one negative lug.
The lug that described positive and negative electrode lug can be drawn for single utmost point group also can be the compound lug of drawing with after the lug stack by a plurality of utmost point groups.
Described positive and negative electrode lug welding can also can be welded on the surface of utmost point group internal start place collector on the surface of the utmost point group outside of utmost point group ending place collector.Promptly can change the derivation direction of lug by the direction that changes them.
The positive pole ear of described battery is identical with the quantity of negative lug or inequality.
The positive pole ear of described battery and negative lug can be arranged on the same side of battery, also can be separately positioned on the not ipsilateral of battery.
Described positive pole ear can be identical from the direction of drawing in the battery with negative lug, also can be different, and also can be any direction.
The shape of described battery can be rectangle, circle, polygon, triangle or rule or irregular geometry, and the molding structure of battery utmost point group can be takeup type or stacked or takeup type lamination.
The utility model is applicable to the various sizes battery, has remedied owing to the not enough low shortcoming of battery specific energy that causes of space utilization.The setting of a plurality of lugs simultaneously can effectively solve the big electric current charge/discharge problem of battery, can make battery in limited spatial dimension; by reducing shared volumes such as protective circuit plate; increase the volume of battery, improve battery capacity, thereby improve the specific capacity of battery.This scheme is used for designing and developing of polymer/flexible-packed battery, and it is simple in structure, and is easy to operation.
