The past century, the Earth’s ecological environment has been severely damaged, in the natural environment has been seriously polluted. The tolerance of the Earth’s ecological environment has been stretched to the limit Lenovo 3000 Y510 battery, for humans a terrible revenge. In recent years, people’s increasing emphasis on protecting the natural ecological environment, water pollution, air pollution, such as white pollution control to varying degrees, had certain effect, but the pollution of used battery has not aroused sufficient attention. Where in the end spent battery containing hazardous substances that do?
Waste battery containing mercury, lead, cadmium, nickel and other heavy metals and acid, alkali and other electrolyte solution, the human body and environment in varying degrees of harm. These toxic substances enter the body through various means, long-term savings is difficult to exclude, it will damage a person’s nervous system, hematopoietic Lenovo E42 battery function and bone, interfering with renal function, reproductive function, it could of chronic poisoning, paralysis, and even cancer.
Waste battery is also a great threat to the natural environment. Ruoqiang spent battery mixed with domestic waste landfill, or throw, and then into the fish, crops, it will destroy the living environment of mankind. Exudation of mercury and heavy metals may penetrate the soil, polluting the groundwater. Experts say that the battery rotten in the geography, make 1 square meter of soil permanent loss of use value; a button cell battery allows 600 tons of water pollution, drinking water is equivalent to the amount of Lenovo IdeaPad U330 battery life.
Although it can be used battery collected to focus on, but because the battery has a cycle of pollution, long concealed-shaped characteristics, if a large number of used battery together in one place, be handled properly, there may cause some parts of the secondary pollution. China’s coastal province of some farmers in the recovery of lead in lead-acid battery, because recycling properly, to contain lead and sulfuric acid waste liquid drained, not only resulted in Lenovo L3000 G230 battery lead poisoning, but also of local crops can not grow. Because of this reason, the relevant departments to collect common focus being promoted temporarily used battery.
At present, the more effective solution is mainly a technical level, is the production of new environmentally friendly battery, gradually replace the existing technology to produce the battery. Green means the battery is not mercury, cadmium and other harmful substances in the environment and human health and the battery. A number of companies today have begun to produce low-mercury battery. Also asked state departments of domestic battery manufacturers learn from experiences of developed countries to gradually reduce the mercury content of battery in 2002, domestic sales of Lenovo 3000 N100 battery to reach low mercury levels of 2006 to reach the level of mercury-free.
However, to make the battery completely do not contain any harmful substances is still pieces of headache thing. Lenovo Ideapad S10e battery Fuel cells as a new, and the most thorough environmental battery, increasingly become the focus of the study one of the rush. Fuel cell is to hydrogen, methanol fuel and air through the electrochemical reaction of the chemical oxygen directly into electrical energy for power generation, the main product is water. Fuel cell power generation efficiency, can be recycled and non-environmental pollution and so on. It can be widely used in space shuttles, electric vehicles, household power supply, portable power supply and communications systems.
Not long ago, the U.S. Lawrence Livermore National Laboratory researchers have successfully developed and demonstrated a micro-thin-film fuel cell samples. General collection, if using this fuel cell, using the estimated time will be extended by 300%. This micro fuel cell technology is to a thin-film fuel cell and a number of microfluidic fuel processing components together into a common packaging, using methanol to facilitate storage of liquid fuels. This fuel cell power modules to provide electricity for longer than existing rechargeable battery, more than 3 times longer. Is anticipated that such cells will become an important alternative to disposable battery. It will reduce by half the number of battery used in the U.S. alone, it is equivalent to an annual total savings of more than 20 billion U.S. dollars. The future of its promotion, can greatly reduce the old-fashioned technology, thousands of tons of waste produced annually by the battery, which greatly reduce these harmful waste Lenovo 3000 N200 battery were contaminated metals on the environment and harm the human body.
Safer for mankind to live on earth, we should start from self, under the protection of human existence on Earth depends.
