Researchers at the Georgia Institute of Technology and the University of Maryland in the United States claimed that they have developed a 100% "green" battery - a super environmentally friendly solar cell made from trees. This battery is "useless". How much land can be contaminated by an abandoned battery? How much water? If a section of a battery is rotted in the ground, toxic substances can make one square meter of land useless, and throwing a button cell into water will cause the pollution of 600,000 liters of water. Is equivalent to one's lifetime water use. When can we abandon these pit batteries? Recently, researchers from the Georgia Institute of Technology and the University of Maryland in the United States claimed that they have developed a 100% "green" battery, which is not the same as our common solar cells - super environmentally friendly solar energy made from trees. Battery, this battery is "used". In fact, conventional solar cells are not environmentally friendly. Bernard Kippelen, head of the Organic Photonics and Electronic Technology Center at the Georgia Institute of Technology, explained that while conventional solar cells can use solar energy to produce clean energy, the batteries themselves cannot be recycled, and humans are only reducing the use of fossil fuels. The dependence, but also consumes other resources, before the birth of this revolutionary battery, this is no different from the Western Wall Western Wall. Ordinary batteries contain heavy metals such as cadmium, lead, and mercury, and heavy metals in used batteries are the culprits of pollution. Researchers believe that to completely change the problem of battery pollution, we must replace the carrier of electric energy. Since the working principle of solar cells is similar to photosynthesis of plants, why can't we directly make batteries from plant fibers? After the screening of thousands of materials, the researchers developed a plant fiber nanocrystal, which only needs to incorporate the organic matter that constitutes the solar cell into this structure to form a simple plant cell. Since this is also a biodegradable material, the battery can dissolve itself in warm water. "The material produced is the plant itself. There are inexhaustible organic matter of light energy. After the battery is used, it can be decomposed by itself and it is 100% environmentally friendly. This is the true green technology." The researchers proudly stated. At present, this new type of battery can convert 2.7% of the plant's light energy into solar energy. The conversion rate is among the highest among organic materials, but it is still far inferior to conventional solar cells (in all types of solar cells, the highest photoelectric conversion efficiency Single crystal silicon, up to 24%). In addition to the lower conversion rate than conventional solar cells, another problem faced by this new type of solar cell is the adaptability to the environment. Since the raw materials of these new types of batteries are degradable, it is probable that a heavy rain will completely destroy the battery products. Drop it. In response, researchers at the University of Maryland have worked hard on the environmental adaptability of batteries. The researchers used nanotechnology to draw materials from the yellow pine, apply a tin film on the wood fiber, and use sodium instead of lithium in the conventional battery. This produced a battery that was thinner than paper and could also provide a degree of water resistance. "Function, thereby increasing the battery's adaptability to the environment." In fact, if these new batteries can be formally put into the production line, it will also improve the health of the workers. Conventional solar cells, especially single-crystal silicon solar cells with the highest photoelectric conversion efficiency, emit silicon as a waste material in the form of chlorine-based gas compounds during the production process. Workers who frequently contact silicon are also susceptible to “silky lungsâ€. "This kind of occupational disease, and this type of solar cell made of trees, the workers do not have to worry about pollution. However, when can I get this piece of wood battery? R&D staff said that their next goal is to increase the conversion rate to double digits. If the research progresses smoothly, the battery will be officially released to the market within five years.
