Description
Technical Field
The invention relates to a preparation method and application of an intelligent temperature-regulating current collector, in particular to a current collector with intelligent temperature-regulating capability.
Background
The lithium ion battery has the advantages of high open-circuit voltage, high energy density, long cycle life, environmental friendliness, small self-discharge and the like, and is widely applied to the fields of electronic equipment, electric automobiles, energy storage systems and the like. However, when the lithium ion battery is in use, if the battery temperature exceeds the normal working range (0-40)oC) And can cause deleterious effects. For example, when the battery temperature suddenly rises (above 60 deg.C) oCAbove), irreversible side reactions occur inside the lithium ion battery, resulting in irreversible degradation of the battery capacity, and even the risk of battery combustion or explosion. For another example, in a low-temperature environment (generally, refer to a temperature below zero), the use of the lithium ion battery is limited, and problems such as sudden drop of electric quantity and difficulty in charging occur, which seriously affects user experience. Therefore, how to control the temperature of the lithium ion battery within the normal operating range is a significant challenge.
In the description of the related documents, the temperature of the battery cell or the battery module is often regulated by means of external energy (such as a heating element, a refrigeration device, etc.). For example, patent CN108107940A proposes an integrated temperature control system and a battery pack. The temperature regulation and control integrated control system comprises a controller, a first temperature sensor, a second temperature sensor, a heating device and an air cooling device, wherein the first temperature sensor, the second temperature sensor, the heating device and the air cooling device are connected with the controller; the first temperature sensor is used for detecting the temperature of the battery box, and the second temperature sensor is used for detecting the temperature of the heating device. The controller selects the control heating device to heat the battery box or the air cooling device to cool the battery box according to the temperature feedback detected by the first temperature sensor; when the second temperature sensor detects that the self temperature of the heating device in the working process exceeds the temperature threshold value, the controller controls the heating device to be closed and stops heating, so that the heating device is protected, and the automatic control of the battery box is realized. For another example, patent CN208939113U proposes a temperature-controlled energy storage module consisting of a box, a controller, an electrical core, a temperature sensor, a metal heat pipe, a flow control instrument, and a liquid nitrogen source. The temperature sensor is arranged on the battery cell and used for detecting the temperature value of the battery cell; the temperature sensor is connected with the controller; the surface of the battery core is provided with a metal heat conduction pipe; the metal heat conduction pipe is connected with the liquid nitrogen source through the flow controller; the flow control instrument is used for controlling the flow speed and flow of the liquid nitrogen; the flow controller is controlled by the controller.
Obviously, such patents have the disadvantages of external energy supply, response time lag (generally, a temperature sensor is needed to measure the temperature and then start heating or cooling), slow temperature regulation (the mode of conducting the temperature outside the battery into the battery), complex structure (a large number of components are needed, including a heating element or a cooling device, a thermistor, a fuse, a switch and the like), low space utilization rate of the battery module (the volumetric capacity and the gravimetric capacity of the battery module are greatly reduced), complex process, high cost and the like.
