Abstract: Provided are a cobalt-free system, a positive electrode slurry, a slurry homogenization method therefor, and the use thereof. The cobalt-free system comprises a cobalt-free material, a binder, a conductive agent and a pH regulator. The cobalt-free system can reduce the rebound degree of the viscosity of a slurry after leaving to stand to the same degree as that of a ternary 811 single crystal, and can also improve the stability of the coating surface density of the cobalt-free material to the same level as that of a ternary material.

Abstract: A heat pipe based passive residual heat removal system for a spent fuel pool (3). Partitions (6) are arranged around an inside of the spent fuel pool. Evaporation-end heat pipes (4) are arranged between the outside of the partitions and an inner wail of the pool. The evaporation-end heat pipes have outlets that extend beyond the pool and are connected to an Inlet of an ascending pipe (10), and have inlets connected to an outlet of a descending pipe (5). Condensation-end heat pipes (7) have inlets connected to an outlet of the ascending pipe, and have outlets connected to an inlet of the descending pipe. The heat pipes cool the spent fuel pool. A heat exchange by phase change of working medium in the heat pipe leads to heat exchange of low temperature difference and high efficiency, relying on density difference for natural circulation drive.

Abstract: A heat pipe based passive residual heat removal system for a spent fuel pool has a plurality of partitions (6) arranged around the inside of a spent fuel pool (3), wherein the heights of the partitions (6) are all lower than the height of the spent fuel pool (3); a plurality of evaporation-end heat pipes (4) are arranged between the outside of the partitions (6) and an inner wall of the spent fuel pool (3), and these evaporation-end heat pipes (4) are divided into several groups. Top outlets of each group of evaporation-end heat pipes (4) are extended beyond the spent fuel pool (3) and are connected to an inlet of an ascending pipe (10). An outlet of the ascending pipe (10) is connected to top inlets of a group of condensation-end heat pipes (7) comprising a plurality of condensation-end heat pipes. Bottom outlets of the group of condensation-end heat pipes (7) are connected to an inlet of a descending pipe (5).

Abstract: An exemplary display device (10) includes a display module (11), a frame (12), a porous material member (13), and a transparent protection plate (14). The frame has a receiving cavity (121). The display module is confined in the receiving cavity of the frame. The transparent protection plate is configured in front of the light output side of the display module. The porous material member is located between the front surface (122) of the frame and the transparent protection plate.
