What are the environmental advantages of lithium battery than the battery?

Source: 2020 - 04 - 24 00:46 hits: time relative to the environment of the strengths of the batteries is lithium battery? Environmental protection battery is put into use in recent years, or is the development of a high performance and non-pollution battery. Lithium battery pack, for example, compared with batteries, lithium-ion battery pack is more energy-saving, environmental protection, no pollution. But for the lithium battery is really environmental protection, there are a lot of controversy, in this paper, the small fill some views, are for reference only. Compared with lead-acid batteries, lithium-ion battery pack the environmental advantages of is what? Traditional lithium battery and lead acid battery electric vehicles use of lead-acid batteries are discarded after will produce large amounts of pollution, and lead to produce steam. According to statistics, a set of waste batteries of electric cars can be tens of thousands of tons of water pollution. It is not easy to lead to discharge from the body, still can cause the body's metabolism, reproductive and nervous system disease, and once found high in the body, can lead to mental decline, fetal abnormalities, easy to cause children malignant tumor, and even death. Compared with batteries, lithium-ion battery pack has a natural environmental protection advantages. Lithium battery packaging materials do not contain harmful heavy metals such as cadmium, lead, mercury pollution metals. Lithium battery in the process of the production and use does not produce any pollution, ensure the human health. Therefore, in the process of waste battery recycling of water and soil pollution problem is very easy to solve. Lithium iron phosphate battery packaging does not contain any heavy metals and rare metals, non-toxic, no matter in the production and use are pollution-free, in line with the European RoHS regulations, is a kind of green battery. In addition, the lithium battery pack also has bigger than can, long cycle life, low self-discharge rate, no memory effect, etc. Lithium battery has high energy storage density, 460 - 600 wh/kg, which is about 6 - of lead-acid batteries Seven times. The anode for lithium iron phosphate batteries, the service life of 6 years, press 1 cdod charging, using 10000 times. Electric car lithium-ion battery pack with high bearing capacity, power can reach 15 - 30 c of charge and discharge capacity, facilitate high strength starting and accelerating. Low self-discharge rate, generally can do 1% / month, less than 1/20 of the nimh batteries; Lithium battery can fully meet the requirements of vehicle dynamics, in addition to the characteristics of the green, environmental protection, has become the ideal product of electric vehicle applications. Lithium battery really green? The point of the development of new energy vehicles, lithium battery pack more environmental protection, the development of the automotive fuel with the development of energy. In the era of oil, gasoline and diesel as vehicle fuel will not only lead to air pollution in cities, but also leads to fuel prices rise due to the oil supply shortage, the second is the emergence of the natural gas vehicle and biofuels as alternative fuel cars. Energy development will gradually transition to a renewable energy, such as the use of solar energy, wind energy power generation of electric cars, finally came to power lithium battery as the main energy storage of new energy vehicles. At present, lithium battery cathode materials mainly include lithium cobalt oxide, lithium manganese acid, lithium iron phosphate, basic with graphite anode materials, such as lithium titanate material. In recent years, as environmental protection in our daily life more and more, we have to consider the material from other sources. Lithium-ion battery pack should be gradually began to artificial material of the positive and negative, rather than blindly extracted from ore required elements, greatly reduce the pollution to the environment.
