Description
Technical field
The present invention relates to a kind of assemble method of ferric phosphate lithium cell.
Background technology
Lithium ion battery is a kind of new high-tech product, also a kind of novel high-capacity long-life environment-friendly battery simultaneously, formed by positive/negative plate, solid electrolyte, properties of product are remarkable, are mainly used in the multiple fields such as electric bicycle, electric automobile, battery-operated motor cycle, electric tool, photovoltaic and wind power generation energy accumulation system, intelligent grid energy-storage system, mobile communication base station, electric power, chemical industry, the standby UPS of hospital, EPS power supply, security protection illumination, Portable mobile power source, notebook computer, electronic toy, mine safety appliance, digital product.Compare with NI-G, Ni-MH battery, but the plurality of advantages such as lithium ion battery has that voltage is high, specific energy large, have extended cycle life, security performance is good, self discharge is little, memory-less effect fast charging and discharging, operating temperature range are wide:
1, high-energy-density (more than 120Wh/kg)
Energy density is the energy that Unit Weight provides, the energy that the battery that namely weighs equally provides.The energy density of lithium ion battery the battery than before much higher 1.5-2.5 of Ni-MH battery or nickel-cadmium cell (be doubly), therefore, it is much light that lithium ion battery is wanted.
2, the life-span is long
The life-span of lithium ion battery reaches more than 500-2000 time, even the ground use of high-power, high frequency, its cycle life also is much higher than NI-G, Ni-MH battery.Because lithium ion battery does not have memory effect, can replenish at any time, battery efficiency can be given full play to, and NI-G, Ni-MH battery often have the phenomenon of having used half and having had to discharge and recharge, its actual access times are had a greatly reduced quality.
3, monomer rated voltage higher (3.2V)
Lithium ion battery discharges into latter stage, and stable operating voltage also is equivalent to NI-G and Ni-MH battery 3 times.As video camera, power supply is in series by multiple batteries, take NP type video camera as example, if adopt NI-G or Ni-MH battery, need to be connected into battery pack with the 11-12 joint, and adopt lithium ion battery, only need with 4 joint series connection just passable, greatly reduce the quantity of serial connection battery, thereby alleviated the weight of monoblock battery.
4, possesses the high power holding capacity
Lithium ion battery has large current work characteristic, and lasting high-quality electric energy can be provided, and can fully satisfy the power requirement of each related load of application apparatus, shows good constant pressure source characteristic, and can complete fast charge and discharge process.Simultaneously, the lithium ion battery group is also built-in intelligent protection circuit is monitored at any time to voltage, electric current, temperature, has greatly improved the fail safe of battery.
5, lower self-discharge rate
Self-discharge rate is called again the electric charge conservation rate, refers to that what of automatic discharging battery lay up.The self-discharge rate of Ni-MH battery reaches 60% per month, and nickel-cadmium cell reaches 30% per month, and the self-discharge rate of lithium ion battery is per month below 6%.
6, environmental protection
Lithium ion battery does not contain the poisonous elements such as any mercury, cadmium, is real environmental protection battery.
The performance of lithium ion battery and life-span, the quality of its packaging technology also can produce critical impact to its battery cycle life and security performance except the factor of LiFePO4 battery core.
At present, the assembling of commercially available ferric phosphate lithium cell relies on artificial mostly, and its structure is except lacking the safety guarantee parts outside battery core, and its packaging technology falls behind, and is unfavorable for battery life and safety.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, a kind of packaging technology of ferric phosphate lithium cell is provided, add the safety guarantee parts, optimized assembling process, the fail safe of battery, reliability and life-span all increase greatly.
Concrete technology path case of the present invention is:
A kind of packaging technology of ferric phosphate lithium cell comprises the following steps:
1) battery core test pairing;
2) the battery core groove pastes the flame-retardant sponge bar and utilizes flame-retardant sponge to carry out the battery core isolation;
3) keyset that sets of battery core adds tin, welding winding displacement;
4) rear composition battery pack is welded in good battery core combination will to match isolation;
5) aforementioned battery pack is carried out solder joint insulation and welding protection;
6) baffle after will be after tested is with battery pack links and carry out fixed insulation, formation battery semi-finished product;
7) the battery semi-finished product are carried out pack into after charge-discharge test fixing in battery container, control board and fuse are installed by the place at the housing protecgulum, and carry out cell degradation;
8) battery finished product outbound after finished product test of obtaining of step 7).
Shell of socket after the isolation of prior art ferric phosphate lithium cell packaging technology battery core adopts gummed paper to be wound around mostly, then close-packed arrays is fixed in battery container, the time-consuming material that takes of this isolation method, compact arranged mode in the situation that there is the pyrophoric risk of producing in strenuous exercise, is a potential safety hazard.The present invention has given up the conventional method that gummed paper is wound around, and utilizes flame-retardant sponge to carry out isolation between battery core, as the safety guarantee parts, have the simple characteristics of technique, giving up compact arranged mode has increased the battery core spacing, has reduced the probability that spark produces, and flame-retardant sponge also has fire-retardant effect simultaneously.
In prior art, baffle and battery pack link by welding, there is no the fixed insulation step, and the inventor finds in actual production, by wire welding, exist electric wire to drop and the risk of crosstalk short circuit between the baffle that welding is good and battery pack.The inventor efficiently solves the problems referred to above by setting up the fixed insulation step.
