Body.
Background technology
Come into advances in technology with the enhancing of human environment protection consciousness, green energy resource industry both domestic and external
In the stage of high speed development, be used for anode by carbon, lithium-transition metal composite oxide be used for cathode and by carbonate mixture
High capacity lithium ion battery for electrolyte has started extensive use.
Traditional secondary cell (lead-acid battery, nickel-cadmium cell etc.) due to its high pollution (production process and material), have
The major defects such as toxicity (lead, cadmium), low energy densities low-voltage platform can not meet current many new technological industries and nature
The growth requirement of environment.The application of lead-acid accumulator history more than 100 years existing, brings to human survival natural environment
Huge destruction.
Novel environment friendly lithium ion power/energy-storage battery is primarily referred to as that (LiFePO 4, nickel cobalt manganese are multiple with novel anode material
Close ternary, LiMn2O4 etc.) secondary cell with higher energy density that is characterized.With traditional high pollution, poisonous plumbic acid
Battery and ni-Cd are compared, and new type lithium ion battery has the advantages that following prominent:Single battery can realize large capacity and high-energy
Density (capacity is more than 3 times of lead-acid battery under equivalent weight, and equivalent capability lower volume is 1/3 of lead-acid battery or so), put certainly
Electric rate is low and retention of charge is strong, using have extended cycle life, high security, using simple non-maintaining, material non-toxic without dirt
Dye and clean environment firendly with it is environmental-friendly.
Therefore, lithium ion battery is expanded as mobile power its application field scope constantly.It is civilian to be produced from information
Industry (mobile phone, PDA, laptop, electronic equipment etc.) expand to Modern Traffic industry (electric automobile, electric bicycle,
Electronic special vehicle etc.), new energy energy storage industry (distributed micro-capacitance sensor, solar energy power accumulating application, the electric power storage of wind energy power station, communication
Railway and power equipment backup power supply, ups power etc.), it is military, cover extra large (submarine, underwater robot), land (the various back ofs the body
Negative formula signal equipment, infantry soldiers system, machine soldier etc.), day (unmanned aerial vehicle), empty (satellite, airship etc.) all arm of the services etc..This
A little weight ratio, volume ratio, security, the encapsulating structure of battery pack and productions extensively using the power module formed to lithium battery
Efficiency etc. proposes the requirement of higher.
Li-ion batteries piles power supply be typically by multiple lithium-ion battery monomers by and go here and there assembled package and form.In great Rong
Amount, high power, high-tension lithium ion battery power supply production in, typically by battery cell carry out tandem compound realize it is high
Pressure, carries out parallel combination by battery cell and improves capacity.Wherein, lithium-ion battery monomer has aluminum hull/steel according to the difference of housing
Two kinds of housing battery and soft-package battery.Mainly there is square and two kinds of cylinder at present according to the difference of shape.Aluminum hull/box hat battery cell
Have the advantages that intensity is high, crushing resistance is good, safe, exterior easy for assembly;Flexible package lithium cell monomer, although shape is plastic
Property is strong, and volume energy density is big, but monomer encapsulation technology still has much room for improvement, in the prior art using flexible package lithium cell monomer shape
Into power supply, poor radiation is complicated not to be easily assembled, while safe protective effect, service life can not be played to battery
It is short.
Generally, the application of current large-scale high-power dynamic lithium battery is still with square and cylindrical lithium ion power cell
For mainstream.
