Electric stroller 12V80AH sealing maintenance battery charging methodAccording to the International Journal of Science, Science, China, the battery research team from China Nankai University has * new research progress in the field of solar cells – they have prepared a solar cell based on organic semiconductor materials, Energy conversion efficiency (the efficiency of converting light energy into electrical energy) reached 17.3%, and the performance of 166 days later was only slight attenuated (about 4%).

What is 17.3%? It can be said that it exceeds the high value of the current at least 14% of the same organic solar cell efficiency, setting a new world record – improve the progress of each percentage point in terms of increasing energy conversion.

Solar cells, maybe everyone is unfamiliar. But specifically, the material of manufacturing solar cells may not understand. At present, most commercial solar panels are manufactured by inorganic semiconductor materials, which have raw materials to acquire (such as silicon), absorption spectroscopy, and high energy conversion efficiency. But in fact, inorganic semiconductor materials are not perfect solutions for solar energy into electrical energy. The reason is that they are too crumblish, and scientists must continue to develop and find alternative solutions.

Organic solar cells have been a research hotspot in academic and industrial communities in recent years. In addition, scientists generally believe that if the battery device configuration and material selection can be continuously optimized, the energy conversion efficiency of organic solar cells can theoretically break through 25%. Especially in the past decade, organic solar cells have experienced transition development, and their performance can be compared with commercial inorganic silicon batteries, just like a high level of crown, encouraged scientists constantly approaching it.

However, we are still a distance from the real organic solar cell, there are still some problems need to be overcome – for example, many organic materials are not so stable under irradiation of sunlight, and the solvent toxicity used during production is large. And the large-scale production process is not yet mature.

Type of Huizhong high energy battery

1 Magnesium dry high energy cells of magnesium as negative electrode active substances: its structure is substantially the same as zinc-manganese dry batteries. The standard electrode potential of magnesium is relatively low, and the electrochemical equivalent is small, and there is excellent conditions for high energy battery negative active substances. For example, the actual amount of magnesium-manganese dry battery is 4 times the zinc-manganese dry battery, and the voltage is stable in operation, and there is a good working ability at low temperatures, and can be stored with high temperature. The disadvantage is that there is a voltage lag (after the connection is required, the voltage can rise to the termination voltage value), the lag time is about 2 ~ 3 seconds; the magnesium electrode current is low; not suitable for small current long time Intermittent discharge.

3 lithium-nonaqueous electrolyte solution high energy battery: lithium electrochemical equivalents is about one-half of magnesium, so as the negative electrode of high energy cells, lithium is more preferable than magnesium. However, lithium is intensely reacted with water, and the electrolyte solution is required to be formulated with an organic solvent or a non-water inorganic solvent to add inorganic salts. The positive electrode material used is mainly solid fluoride, chloride, oxide, sulfide. These batteries are mostly more energy to 1000 watts / kg. Its actual is relatively high. For example, lithium-fluorinated copper (Li / Cuf2) battery When the discharge current density is 2 mA / cm 2, the actual amount of energy can reach 250 watts / kg. Since the specific electrolyte solution is small, the current density cannot be improved, so the lithium-nonaqueous electrolyte solution is a high-proportioned energy, low-power battery. Lithium-sulfide batteries are discharged under heavy load, especially when the external is short-circuited.
