Electrokinetic cell mainly comprises two kinds at present, and a kind of is lead-acid battery, and a kind of is lithium ion battery.
Lead-acid battery is to adopt the plastic cement shell to encapsulate, structure is comparatively easy, but owing to be packaged with electrolyte in the lead-acid battery, the plastic cement shell must be a complete closed, to prevent the leakage of electrolyte, can only discard after battery uses up, the channel by specialty reclaims, otherwise can bring great destruction to environment.Therefore, in today of paying attention to environmental protection day by day, lead-acid battery is applied fewer and fewerily, the substitute is the lithium ion battery group.
The negative pole of lithium ion battery is a graphite material, and there are not noxious substances such as heavy metal in positive pole with LiMn2O4, ternary material, LiFePO 4 etc. in the lithium ion battery, therefore is called as " green battery ", is subjected to increasing concern of people and use.But in concrete use, people do not encapsulate lithium ion battery, but only adopt simple connection in series-parallel form to connect, for single lithium ion battery based on its applied situation, it is understandable not adopting encapsulation, but under the situation about using simultaneously for a plurality of lithium ion batteries, the occupation mode of packaged type does not badly influence the safety of circuit, has increased the danger that lithium ion battery is destroyed by external force.
Summary of the invention
Based on this, the purpose of this utility model provides a kind of lithium ion battery group of plastic cement encapsulation, and this battery pack adopts encapsulating structure to protect, and has guaranteed the safe in utilization of lithium ion battery group.
Another purpose of the present utility model provides a kind of lithium ion battery group of plastic cement encapsulation, and this battery pack structure is simple, is easy to realize, can be widely used in the available dynamic battery.
In order to achieve the above object, the utility model is achieved in that
A kind of lithium ion battery group of plastic cement encapsulation, it includes a plurality of lithium ion batteries, it is characterized in that described lithium ion battery is arranged in the encapsulating shell, described encapsulating shell comprises battery case and cap, and battery case has a containing cavity, and a plurality of lithium ion batteries are ordered in the containing cavity, and be electrically connected, power supply connects the head and the tail of a plurality of lithium ion batteries, forms the connection in series-parallel battery pack, and draws from cap.
Have power supply sign on the described cap and draw the both positive and negative polarity outlet terminal of power supply, wherein the both positive and negative polarity outlet terminal has certain spacing, so that carry out mark by the power supply sign, keeps the safe distance of output simultaneously, avoids short circuit phenomenon.
A kind of reasonable mode is the both positive and negative polarity outlet terminal to be located at the both sides of cap, and further, the both sides of cap have groove respectively, and the both positive and negative polarity outlet terminal is drawn from described groove.
The cross section of described battery case can be rectangle, triangle, circle, any one shape such as trapezoidal, also can be irregularly shaped.
For battery case, cap, their formation shape can be identical or different, as long as cap can intactly encapsulate battery case; Simultaneously, battery case, cap are made of the high molecular weight plastic material, can be by the ABS(acrylonitrile-butadiene-styrene copolymer) or the PC(Merlon), the PP(polypropylene), the PE(polyethylene), the PET(polyethylene terephthalate) etc. one or several mix, can adopt above-mentioned material to make during concrete the making, but be not limited to above-mentioned material.
Described at battery case or/and the cap outer surface also can be provided with handle, to increase the convenience of carrying.
Between described battery case and the cap, be provided with fastening structure, so that the installation of lithium ion battery group and maintenance.
The utility model adopts above-mentioned structure; the lithium ion battery group is installed in the battery case, has obtained protection well, in use; can not constitute influence, guarantee the safe in utilization of lithium ion battery group each lithium ion battery and the circuit of lithium ion battery group.
The utility model is simple in structure, be easy to realize, can be widely used in the lithium ion battery group of existing electrokinetic cell.
