In lithium battery store can in the system, lithium battery basically results from to the sensitivity of temperature the temperature sensitivity that its stuff other people changes character. Temperature can affect ion of the active of electrode material and conductivity, lithium to go up in electrode directly embed and take off embed, diaphragmatic lithium ion passes through a gender to wait, affect the electrochemistry reaction of batteries interior then, its are exterior the temperature sensitivity that expression is dynamical cell. Because dynamical cell has appropriate working temperature range, the active that adds substance of its interior active as temperature inside this limits is bigger, the fills spark voltage and capacity to increase cell subsequently internal resistance of batteries is reduced accordingly, of dynamical cell fill discharge efficiency to also increase accordingly.

 

But, exceed certain range when temperature, temperature meets those who accelerate batteries interior deputy reaction high to undertake too, these deputy reaction use up lithium ion, dissolvent and electrolyte to wait, bring about batteries function attenuation. Consider to make clear, work continuously when batteries when 45 ℃ above, its cycling life is reduced apparently, this kind of case is more clear when tall fold charges discharge.

 

Accordingly, if for long job is below high temperature environment, the life of dynamical cell can shorten apparently, its function also can be reduced greatly, cause safe accident even. Same, temperature is too low the active of active material reduces a batteries interior apparently, voltage of the group inside its, polarization increases, fill discharge power and capacity to all can be reduced significantly, cause batteries capacity to cannot go against attenuation even, bury next safe hidden trouble. Charging especially in the process, charging action of adscititious electric field leaves facility, lithium ion enters electrolyte from the emergence in positive electrode material and move to negative pole, ordinal in entering the negative pole material that black lead makes, form LiC compound. If temperature is reduced, charge rate is too rapid, can make lithium ionic have not enough time to enter negative pole to form LiC compound, the lithium ion that stands by negative pole becomes metallic lithium with respect to meeting capture electron, gather form lithium branch brilliant, lithium branch brilliant is brought up to be pricked possibly broken diaphragmatic form short circuit.

 

Additional, field of temperature of batteries casing interior is long inhomogenous the disequilibrium that distributings to also can cause function of each batteries module, monomer, distributing to be met in the batteries ageing rate of high temperature area especially apparently fast at microtherm part, differ as the accumulation of time the content sex difference between batteries will be added more apparent, make thereby the consistency between batteries becomes poor, happen even ahead of schedule invalidation, shortened the life of system of whole power cell.

 

 

Connector serves as batteries group between the essential element of series-parallel connection, when batteries group undertakes full discharging, of big electric current give birth to fuel factor through can making connector is produced, lift when connector temperature, exceed the temperature of batteries group, temperature can be passed to batteries interior, affect the stability of batteries then, the character that makes connector achieves small temperature rise so makes a requirement, move repeatedly store the terminal technology that can special connector used company own intellectual property, maintain terminal interior with the interface that insert a needle in optimal area, reduce osculatory resistance effectively, had reduced current density, reduced voltaic temperature rise; Meanwhile, new-style exterior is designed, many outsides the design becomes moire sector, rose to come loose hot function; Besides, metallic stuff uses red copper of entrance tall purity, conductivity is tall, cross stability of voltaic temperature rise, plasticity material uses peculiar alloy data, gather a variety of plastic character, have both high strenth and tall tenacity characteristic, contented fire prevention asks at the same time, have taller coefficient of thermal conductivity, accelerate medicinal powder hot; Interiorly terminal and respect of technology of line nose join, use FIRST patent technology, assured both join dependability, increased interface to accumulate, had made voltaic temperature rise is achieved reduce effectively, in the meantime, craft of stable and firm many bits of crimp reduced the link temperature rise between line bazoo and lead effectively, assured the consistency of temperature rise. The temperature rise test of connector of grade of current and different electric current all can control the company as a result it is under 35 Celsius (environmental temperature 20 Celsius) .

 

Lithium battery store a can be times development inevitable trend, assuring the on the safe side of lithium battery to move is store can the first requirement that the system runs, connector of big electric current regards lithium as batteries store can indispensable one part, jiangsu moves power limited company to hold to the products plan concept of safe, reliable, environmental protection from beginning to end repeatedly, for store can lithium battery offers product of appropriative electric coupler.
