Abstract
The utility model relates to a lithium-ion battery for miner's lamps, and comprises cell cores. A cell core consists of a positive pole, a negative pole and a separating membrane, and contains electrolyte, which separates the positive pole and negative pole. The positive pole and negative pole are separately connected with the positive pole ear and the negative pole ear, which are directly welded with the protective circuit board. The protective circuit board is integrated into the cell core, and the cell core is made of stacks and coated with the aluminum plastic film outside. The utility model has advantages of reasonable structure and design, low cost, excellent safety performance, and more convenient and effective management of the overcharge and over-discharge of the cell.
Description
Technical field
The utility model relates to a kind of lithium ion battery, particularly a kind of mine lamp lithium ion battery.
Background technology
At present, the employed mine lamp of mining under the mine adopts the common lead acid accumulator as power supply mostly, its power supply volume is big, and corresponding weight is also big, and inconvenient miner carries, and difficult the maintenance, not only need every day and clean, regular maintenance such as charging, also must regularly replace plumbic acid liquid.What make the headache of user is that also there is problems such as leaking acid in the power supply of lead-acid mine lamp, and environment is also had suitable pollution.There is the part mine lamp to adopt Ni-MH battery now as power supply, though this mine lamp has solved the part deficiency of lead-acid mine lamp, but discharge voltage is low, and the cell capacity is not high, usually needs to carry out the connection in series-parallel technology and forms a battery pack, owing to existing the battery pack balancing problem to cause safety in production hidden danger, and series-parallel number of battery cells is many more, and harmony is poor more, brings inconvenience to management, thereby, fundamentally do not solve the existing problem of plumbic acid mine lamp.
Summary of the invention
Technical problem to be solved in the utility model provide a kind of reasonable in design, with low cost, security performance is good and eco-friendly mine lamp lithium ion battery.
It is this mine lamp lithium ion battery that the utility model solves the problems of the technologies described above the technical scheme that is adopted; comprise battery; battery is made up of positive pole, negative pole and barrier film; contain electrolyte, anodal and negative pole separates by barrier film, and its design feature is: also comprise the protective circuit plate; protective circuit plate and positive and negative electrode lug directly weld; adopt and the battery integrated design, the entire cell core is made by lamination, is coated with aluminum plastic film in the outside of battery.
One side of positive pole described in the utility model is coated on the aluminium collector by the LiFePO4 diaphragm, negative pole one side by coated with graphite in the copper collector.
The utility model compared with prior art, have the following advantages and effect: 1, reasonable in design, the entire cell core is made by lamination, technology is simple, adopt the aluminum plastic film soft package structure to make the battery shape be easy to design, be suitable for being assembled into power supply, the incorporate mining safety helmet lamp of lamp holder, make mine lamp be tending towards miniaturization; 2, protective circuit plate and battery integrated design are rational in infrastructure, to over-charging of battery, cross and to put defencive function and make battery management more convenient, effective; 3, positive electrode adopts LiFePO4, its charging/discharging voltage window is 3.3～3.6V, this interval coincide with the forward voltage drop 3.0～4.0V of present mine lamp with LED (light emitting diode light-emitting diode) cold light source in ten minutes, and discharge voltage is very steady, can reduce stable-pressure device, reduce structural design; 4, the positive electrode design makes the anode pole piece Stability Analysis of Structures, and cycle performance of battery is good, and no oxygen is emitted in the discharge process, and the battery design cost is reduced, and security performance improves greatly, and it is friendly that environment is tending towards.This shows that the utility model can satisfy safety and the environmental requirement of mine lamp with battery well, is the mine lamp battery that a kind of utmost point has application prospect.
