Description
Technical field
The present invention is meant a kind of manufacture method of large-capacity power type lithium ion battery pack especially about a kind of manufacture method of lithium ion battery group.
Background technology
Lithium ion battery be last century the nineties develop and begin to realize commercial, its appearance deserve to be called secondary cell historical once the leap, subsequently ten surplus year in, its commercialization process has obtained the development of advancing by leaps and bounds.The range of application of lithium ion battery also thereby is constantly widened, and to energy traffic, under water, lithium ion battery has entered the every field of human society from space from information industry.
Lithium ion battery is divided into primary cell and secondary cell two classes, the non-rechargeabel disposable lithium-battery of main use in the lower electronic product of power consumption such as camera then uses the secondary lithium battery that can discharge and recharge in the bigger electronic product of power consumption such as video camera, digital camera, mobile phone and notebook computer.Compare with other storage batterys, the advantage of lithium ion battery is voltage height, high-energy-density, self-discharge rate is low, the life-span is long.Not having memory effect also is the dark outstanding advantage popular to people of lithium ion battery, is that other secondary cell is not available, and whether the electric weight that people needn't take into account before lithium ion cell charging wherein runs out.
Lithium ion battery is made up of positive pole, negative pole, electrolyte, barrier film and five parts of container, wherein most importantly positive pole, negative pole and three parts of electrolyte.No matter at both positive and negative polarity or in battery diaphragm, lithium all exists with ionic species in kalium ion battery.The negative pole of lithium ion battery is a carbon materials, and is anodal then be the transition metal oxide that contains lithium as graphite etc., as LiCoO2, LiMn2O4 etc.Electrolyte is the organic solution that contains lithium salts.Lithium ion battery work (charge or discharge) process in, lithium ion directed movement in both positive and negative polarity and electrolyte membrance.During charging, potassium ion is deviate from from positive electrode under the driving of electric field, through electrolyte, is inserted in the negative pole.During discharge, process is just in time opposite, and promptly lithium ion returns in the positive pole, and electronics has then passed through in the electronic product of electricity consumption and power supply for it.
At present, lithium ion battery is widely used in the vehicle, i.e. power lithium-ion battery.For power lithium-ion battery a basic requirement being arranged is exactly that capacity is wanted height, could powered vehicle drive to certain distance like this, can satisfy certain trip needs.Therefore, the monomer of current driving force lithium ion battery is done bigger and bigger, and this not only makes the cost height, and security reliability is low.
Therefore, need a kind of easy manufacturing and the high large-capacity power type lithium ion battery of dependability.
Summary of the invention
Therefore, the object of the present invention is to provide a kind of manufacture method of large-capacity power type lithium ion battery pack, it will be by being easy to make and stable minor comonomer makes up, form the large-capacity power type lithium ion battery pack, to satisfy power-type lithium ion battery high voltage and jumbo requirement, thereby be convenient to make, cost is low, and security reliability is good.
For being implemented in above-mentioned purpose, the invention provides a kind of manufacture method of large-capacity power type lithium ion battery pack, comprise the steps: step 1, cell is provided; Step 2, several cells in parallel are formed a battery unit module; Step 3, several battery unit modules of connecting are formed a battery time composite module; Step 4, several batteries time composite module in parallel are formed a battery pack.
The manufacture method of large-capacity power type lithium ion battery pack of the present invention will be by being easy to make and stable minor comonomer battery makes up, form the large-capacity power type lithium ion battery pack, to satisfy power-type lithium ion battery high voltage and jumbo requirement, thereby be convenient to make, cost is low, and good reliability.
