Solar Battery takes an important rule in solar lighting, Could divide into Gelled Type and Lead-acid Type.
Gelled Batteries, or "Gel Cells" contain acid that has been "gelled" by the addition of Silica Gel, turning the acid into a solid mass that looks like gooey Jell-O.
The advantage of these batteries is that it is impossible to spill acid even if they are broken.
Other Advantages of BR Solar Solar Battery:
1.)Real Green Power
2.)Low Internal Resistance
3.)Low Self-discharging Rate
4.)Low Gassing Rate
5.)Long-life Design
6.)Wider Temperature Range
7.)Extremely good discharge recovery ability

On the morning of February 14, the National Science and Technology Awards Conference was held in Beijing. The meeting read "Decision of the State Council on the 2011 National Science and Technology Awards." The “Overhead Line Clearance Detection Robot†independently developed by Shandong Electric Power Super High Voltage Co., Ltd. won the second prize of National Science and Technology Progress Award.
This kind of robot was independently developed by the Gao Sen team, a front-line worker of Shandong Electric Super High Voltage Co., Ltd. It is understood that this is the only project that won this honor in front-line workers' technological innovation in Shandong this year. This project is aimed at short-circuit discharge caused by foreign objects hung on high-voltage lines. It aims to change the traditional methods of removing obstacles, and quickly and effectively remove foreign materials without affecting the power supply of the grid and improve the reliability of the power grid. The robot includes more than 700 pieces of molds such as pulleys, robots, and circuit boards. The robot consists of a walking device, a remote control device, an operating device, and a power device, and can perform line inspections, inspections, obstacle clearing, and video cutting without power interruption of the high-voltage transmission line. Functions such as monitoring and wireless transmission have four technical innovation points: live operation, automatic obstacle crossing, anti-interference under strong electromagnetic fields, and patrol clearance of foreign objects. The robot will be applied to more than 70 500 kV transmission lines under the jurisdiction of Shandong Power Grid.
The 2011 National Science and Technology Awards awarded 374 projects and 10 technical experts. Among them, academician of the Chinese Academy of Sciences and former deputy director of the Institute of High Energy Physics of the Chinese Academy of Sciences Xie Jialin, academician of the Chinese Academy of Sciences, academician of the Chinese Academy of Engineering, and director of the Institute of Architecture and Urban Studies of Tsinghua University Wu Liangbiao received the 2011 National Top Science and Technology Award; National Natural Science Award awarded 36 items of the project; 55 awards awarded by the National Technological Invention Award; 283 awards awarded by the National Science and Technology Progress Award, including 1 special award, 20 first prizes and 262 second prizes; 8 foreign scientists granted to the People’s Republic of China International Science and Technology Cooperation Award.
