The non-coating base plate surface ends of the positive pole sheet and the negative pole sheet of the battery core body are distributed in an opposite direction, and the non-coating base plate surface ends of the positive pole sheet and the negative pole sheet are respectively connected with a bundle head with a pole column in a binding mode. The utility model is characterized in that the bundle heads at both ends are respectively provided with at least two output pole columns, and a plurality of positive pole columns and negative pole columns which are arranged at both ends of the battery core body are respectively led from both ends of the casing body. By the method that the output pole columns are added on the bundle heads, the output quantity of the same battery is increased so as to meet requirements of the running power supply of a high-power device. The utility model is also suitable for a low-power device, and can select output quantity to be suitable for power supply requirements of various loading conditions according to requirements. The technical scheme of the utility model is suitable for a liquid state lithium ion battery, a semi-solid state lithium ion battery and a solid state polymer lithium ion battery.

Description

Lithium ion battery of supplying high power output with multiple terminals
[technical field]
The utility model relates to lithium ion battery, especially a kind of lithium ion battery of supplying high power output with multiple terminals.
[technical background]
At present, for increasing the charge storage ability of lithium ion battery, to prolong the discharge time of lithium ion battery, manufacturer has proposed much can improve the technical scheme of capacity of lithium ion battery, as Chinese patent CN1307376A " a kind of rechargeable Cr-F-Li solid electrokinetic cell ", CN2615878Y " but repeated charge large-capacity power lithium battery of architecture advances ", CN2615877Y " but high-voltage lithium ion batteries of repeated charge " etc., provide practicable technical scheme for making high capacity lithium ion battery, can see from disclosed patent documentation, existing high capacity lithium ion battery all adopts the multilayer positive/negative plate to stack structure, just is being provided with two in being full of the housing of electrolyte that is:, negative plate and barrier film stack the core of lithium ion cell of formation.The one or both ends of housing are respectively equipped with single positive pole output pole and negative pole output pole.High capacity lithium ion battery has prolonged its ability to work greatly, can satisfy the needs of the long-time output of electric energy, has solved the little defective of common lithium battery reserve of electricity.But be subjected to its structural restriction, the lithium ion battery of existing single both positive and negative polarity output is when being the powerful device power supply of some special requirement moment startups, need to be equipped with the high capacity lithium ion battery of the single output of many groups, the outfit of many group high capacity lithium ion batteries not only can increase the operating cost of equipment, can increase the weight of equipment simultaneously because of the setting of many group lithium ion batteries, give moving, transport, install and using and all can make troubles of equipment.
[summary of the invention]
The purpose of this utility model is the deficiency that exists at above-mentioned high capacity lithium ion battery, and a kind of lithium ion battery of supplying high power output with multiple terminals that can satisfy powerful device operation needs is provided.
The utility model lithium ion battery of supplying high power output with multiple terminals comprises: be filled with electrolyte housing, replace assonance by two above rectangle sheet positive electrode plate and negative electrode plate of lithium ion battery and barrier film and pile up the battery core body that constitutes, and the electrolyte that is full of housing; The uncoated substrate face end of the positive/negative plate of battery core body is arranged in the opposite direction, and positive and negative plate uncoated substrate face end is connected by the bookbinding of band pole bundle head respectively, it is characterized in that: be provided with two output poles on the bundle head of two ends respectively at least; The positive and negative pole at core body two ends is drawn from the two ends of housing respectively, forms a plurality of positive output pole A and a plurality of negative output pole B.
The utility model lithium ion battery of supplying high power output with multiple terminals design science, rational in infrastructure.Its design principle is identical with disclosed patent documentation, and difference is: by increase the method for output pole on the bundle head, increase the output variable of same battery, to satisfy the needs of powerful device operation power supply; The lithium ion battery of this multipole post export structure can be selected choosing output as required when being used for low-power equipment, therefore, its scope of application is widened greatly, and the power supply that can be suitable for various different loads condition equipment needs.The technical scheme of the utility model is applicable to liquid lithium ionic cell, semisolid lithium ion battery, also is applicable to the solid polymer lithium ion battery.
