The utility model provides a pole piece, a single battery and a battery, the pole piece comprises a current collector and an active material layer, the current collector comprises a main body part, the main body part extends towards two sides to form two protruding parts, meanwhile, the main body part further extends outwards to form a pole lug, and the pole lug and one protruding part are located on the same side of the current collector. Therefore, the protruding part is formed in the area, where the tab is not arranged, of the main body part, and the arrangement of the tab and the connection between the tab and other parts cannot be affected by the arrangement of the protruding part. When the pole piece is applied to the battery, the protruding part protruding out of the main body part can occupy the space between the main body part and the cover plate, so that the spare space between the main body part and the cover plate can be effectively utilized, and the space utilization rate in the battery is improved; the active material layer is arranged on the surfaces of the main body part and each protruding part, so that the coating area of the active material layer can be increased, and the volume energy density of the battery is further improved.

This invention relates to the field of air pollution control technology, specifically a high-temperature flue gas emission desulfurization and denitrification device, comprising a denitrification mechanism and a desulfurization mechanism. The denitrification mechanism employs a vacuum-jacketed mounting cylinder, which contains an array of denitrification arc-shaped guide holes and a combined denitrification module. The module includes a denitrification guide cylinder, an arc-shaped filter screen, and a limiting guide cylinder with oblique guide grooves, effectively expanding the catalytic area and uniformly distributing the flow. A back-blowing fan and an elastically limiting rotating guide plate are also included to achieve online vibration self-cleaning. The desulfurization mechanism introduces flue gas into the desulfurization mounting cylinder through a gradient annular guide cylinder and uniformly enlarging inlet holes from top to bottom, forming a gradient three-dimensional desulfurization. A bottom discharge drive and a spiral guide plate ensure uniform catalyst renewal. This device has a compact structure, excellent insulation and airflow organization, and solves problems such as ash accumulation and blockage, difficult maintenance, and low catalyst utilization in existing technologies, thus improving denitrification and desulfurization efficiency and continuous operation stability.

The utility model provides a kind of pole piece structure, roll core pole group and cylindrical battery, including pole piece body, pole piece body has coating area, several pole lug areas are arranged at interval along the length direction of pole piece body, at least one pole lug area is equipped with at least 2 pole lug arranged at interval between pole lug area, and pole lug is connected to the long side of pole piece body;Pole piece structure is after participating in winding and forms roll core pole group, and the pole lug area on pole piece structure is arranged at radial in the center hole of roll core pole group towards one end surface of roll core pole group.
