Concept is gaining popularity as a low-carbon, the battery can lead to a growing concern.
The batteries and pollution
The batteries pollution potential has attracted considerable attention. China is a global leader in the production of a battery and energy consumption, has information that China currently has more than 1,400 battery manufacturers, production capacity of the battery in 1980 compared to U.S. U.S. and ranks first in the world. Production of dry batteries in China in 1998 reached 14 billion, while total world production of dry batteries is approximately 30 billion dollars. dell xps m1530 battery dell vostro 1510 battery
Such a large number of batteries, which makes a big problem is exposed, is the amount of pollution that the batteries are not destroying our environment. If the first cell on the ground rotting, it’s toxic substances can make a square meter of land lost value, throw a coin cell in the water it contains toxic substances that cause pollution of 600,000 gallons water in the body, the water equivalent of a person’s life; batteries contain cadmium, lead, mercury, nickel, zinc, manganese, cadmium, lead, mercury is most harmful substances from the human body. hp compaq 8510p battery sony vaio vgn-fz battery
Therefore, the collection and disposal of spent batteries is very important, if you throw badly, perhaps on the ecological environment and serious harm to human health. Although the technology has given us the right direction, but my battery is not optimistic pollution phenomenon. Currently, most of our garbage is mixed with used batteries to be buried, over time, after conversion to rotting of the battery, the leaching of heavy metals, both can contaminate groundwater they can contaminate soil eventually, through various means in the human food chain. biological uptake of heavy metals from the environment through food chain biomagnification, step by step in higher organisms, thousands of times richer, and then enter the human body through the food chain, resulting in savings certain organs of chronic poisoning, Japan Minamata disease is a typical case of mercury poisoning. sony vgp-bps13 battery
Thin film solar cells Cheng Xinchong
When war internal battle when the party polysilicon thin film solar cells already open seats silently. field production of photovoltaic electricity, the two main “master” cells, crystalline silicon and thin film batteries, seems to draw a contest.
As its name suggests is the layer stack of thin film solar cell thin film silicon is extremely rare and easier to reduce costs, while it is both energy-efficient products, but also a new type of building materials, more easily with the perfect combination of architecture. raw material of silicon on the international market in the context of continuing tension, thin film solar cells has become the international trends of PV market development and hot spots. asus eee pc 1000he battery
Although thin film solar cells have already appeared, but the conversion efficiency is low, attenuation rate were higher, some years ago was not enough to attract the attention of the industry, market share is low. With the continued progress of its technical efficiency of photoelectric conversion 的 been enhanced to Xianzai Nian Bi 2 ago about an improvement of 30% -40%, and silicon cells based Suiranrengran Jingtai big gap, but its use, simple process Liaoshao low energy consumption, costs of certain benefits, more and more accepted by the industry.
Corresponding to this, depending on modules hot sun, the fever of polycrystalline silicon thin film photovoltaic array has become the hot new investment.
Compared to crystalline silicon cells, thin film batteries is much greater potential for cost reduction through rapid technological progress in thin film batteries. Thin-film solar capacity may be the next to reach 20% of the entire solar industry, while just 7.6% in 2007, shows that among the space. dell studio 1535 battery
