Regain road.
The described lithium-ion-power cell with radiator structure, described radiated energy reclaims loop and is taken up an official post by the shell that dispels the heat
Anticipate and be directly connected to form by wire with automobile-used load two ends respectively at two.
The beneficial effects of the utility model are:
As shown from the above technical solution, this utility model is directly set about from cell, solves its heat radiation and ask from root
Topic, effectively reduces the heating up problem of cell, improves cycle life and the security performance of cell, utilizes heat
The Seebeck effect of electric material carries out thermo-electric generation, and the converting heat that cell produces is become electric energy directly to carry by the loop of structure
Supply automobile-used load to use, used heat can be carried out secondary utilization, more energy-conserving and environment-protective.
Accompanying drawing explanation
Fig. 1 is example sketch of the present utility model, and wherein, 1-dispels the heat shell, and 2-radiated energy reclaims loop, and 3-is automobile-used negative
Carry.
Detailed description of the invention
This utility model is further illustrated below in conjunction with the accompanying drawings with specific embodiment.
As it is shown in figure 1, a kind of lithium-ion-power cell with radiator structure, have and be combined by thermoelectric material and aluminum
The heat radiation shell 1(being prepared from instead of existing aluminum hull layer), heat radiation shell 1 and having born on automobile-used load 3(vehicle
Carry) connect, constitute radiated energy and reclaim loop 2, this radiated energy reclaims loop 2 can from cell heat radiation shell 1 arbitrarily
Draw wire at two and be connected directly between automobile-used load 3 two ends.Thermoelectric material uses known thermoelectric material.
The heat produced in lithium-ion-power cell charge and discharge process can make shell temperature raise, the Seebeck of thermo-electric generation
Effect makes thermoelectric material be equivalent to temporary source, is designed by foregoing circuit, can be directly acted on by the electric current of thermo-electric generation
Automobile-used load two ends realize secondary and utilize.The used heat produced in cell charge and discharge process is not only directly turned by this utility model
Chemical conversion power cycles utilizes, and significantly reduces the heating up problem of cell, and then improves lithium ion power
The cycle life of battery and security performance.
Testing example: choose ternary battery, ternary material is Li (Ni0.5Co0.2Mn0.3)O2, will there is heat radiation shell
(aluminum with thermoelectric material be composited) ternary battery five module, after charging with 0.33C under room temperature, more respectively with 0.5C, 1C,
2C, 3C discharge, battery case and the peak temperature of inside under the conditions of record discharge time and multiplying power discharging, concrete data such as table 1
Shown in.
Test comparison example: choose ternary battery, ternary material is Li (Ni0.5Co0.2Mn0.3)O2, will have conventional aluminium shell
Ternary battery five and module, after charging with 0.33C under room temperature, then discharge with 0.5C, 1C, 2C, 3C respectively, record discharge time
And battery case and the peak temperature of inside under the conditions of multiplying power discharging, concrete data are as shown in table 2.
As can be seen from Table 1 and Table 2, there is ternary five the module phase of heat radiation shell (aluminum is composited with thermoelectric material)
More longer than in the ternary five module discharge time with conventional aluminium shell, peak temperature is lower, benefit from heat radiation shell
Thermoelectric material composition, is directly translated into utilization of power by heat energy, extends the battery modules working time, reduces its work temperature
Degree.
The above embodiment is only to be described preferred implementation of the present utility model, not to this practicality
Novel scope is defined, and on the premise of without departing from this utility model design spirit, those of ordinary skill in the art are to this
Various deformation that the technical scheme of utility model is made and improvement, all should fall into the guarantor that claims of the present utility model determine
In the range of protecting.
