    Abstract: An intelligent thermoelectric-battery integrated structure, which belongs to the field of new energy device, is provided. The structure intelligently controls the temperature of the single cells inside the battery pack by means of direct contact, so as to reduce the temperature and cut off the occurrence of thermal runaway from the root cause. In addition, the Seebeck voltage generated based on the temperature difference can directly store energy inside the battery when charging, and can increase the overall output voltage when discharging. The advantage of this structure solves the contradiction between the difficulty of achieving high energy density and high safety performance for traditional batteries at the same time, and provides a practical solution for the development and utilization of a new generation of high-performance batteries.

    Abstract: The present invention discloses CrN thermoelectric material and its preparation method, which belongs to the field of thermoelectric materials. Here, we provide a study for thermoelectric properties, hardness, wear-resisting performance and thermal stability of CrN. These results show that CrN possesses excellent mechanical properties and thermal stability. The hardness of the bulk CrN sample is as high as 735.76 HV, which is far superior to most of thermoelectric materials. The thermogravimetric analysis test indicates that CrN remain stable at 873 K. Friction and wear test results demonstrate that the low friction coefficient (˜0.42) and good wear resistance of CrN. The maximum ZT value of 0.104 is observed at 848 K. In this way, CrN may be a promising thermoelectric material in extreme environment application which requires both mechanical and thermoelectric properties. Such as collision avoidance systems and outerspace.
