China Waste Battery Problem
The potential contamination of waste batteries has caused widespread concern in the community. China is the world's number one battery production and consumption country, our data show that China currently has more than 1,400 battery manufacturers and in the year of 1980, dry battery production has surpassed the United States and ranked first in the world. Dry battery production in China in 1998 reached 14 billion, while the total production of the world's dry battery is about 30 billion at the same year. The large quantity of batteries makes a great deal of problems exposed, and that is, how to make so many silver oxide batteries do not damage the environment that people survive.
Hazardous Substances of Used Batteries
According to the survey, the used batteries contains heavy metals and waste acid, waste alkali electrolyte solution. If improperly discarded, corruption battery will destroy the people's water supply, erosion of human survival crops and land, is facing a huge threat to people's living environment. If a 1st battery rot in the ground, it's toxic substances can make a square meter of land lost value in use; throw a coin cell battery into the water, the toxic substances contained in it which will cause 60 million liters of water pollution, equivalent to the water consumption of a person's life; waste button cell battery contains heavy metals cadmium, lead, mercury, nickel, zinc, manganese, and the larger substances including cadmium, lead, mercury is harmful to human health. While a metal such as nickel, zinc, in a certain concentration range is useful material, but in the environment if it exceeds the limit, and it will also cause harm to humans.
Big Dangers of Waste Batteries
Therefore, the collection and disposal of waste batteries is very important. If disposed improperly, it may cause serious harm to the ecological environment and human health. Feel free to discard used batteries only pollute the environment, but also a waste of resources. Some have calculated that the national annual production of 10 billion battery, the annual consumption of 156,000 tons of zinc, 226,000 tons of manganese dioxide, 2080 tons of copper, 27,000 tons of zinc chloride, 79,000 tons of ammonium chloride, 4.3 ten thousand tons of carbon rod. Despite the advanced technology has been given to the right point, but the battery pollution phenomenon is still not optimistic. The most used batteries mixed with household waste are buried together, over time, after transforming the battery rotting and leaching of heavy metals, may contaminate groundwater bodies, and may contaminate the soil, eventually find their way into the human food chain. And if people absorbs the hazardous food, that will be very dangerous.

Lithium Titanate Tends to Become the Vehicle Battery Power Protagonists
Disadvantages of Lithium Iron Phosphate Battery
As we all know, domestic mainstream vehicle power batteries are commonly used lithium iron phosphate battery cathode material, anode material, separator, and electrolyte composition. Power as a chemical system, is generally within the design range of operating conditions is not easy to spontaneous combustion and other security incidents. However, the lithium ion batteries are used mainly graphite material overcharge is easy to precipitate the lithium dendrite to cause the battery to short-circuit, affecting the safety performance of the lithium battery; Yi SEI film is formed and led to the first charge-discharge efficiency is low, irreversible larger capacity. This makes the vast majority of "dare" fast charge, quick release, but only slow charge form, severely restricted the flexibility and convenience on the use of vehicles, to the promotion and popularization of electric vehicles bring electric vehicles no small obstacle. Last year, several electric vehicle accident occurred this year, lithium batteries have undergone a fire burning phenomenon, making the community raised questions about the security of the electric car, also prompted enterprises to accelerate a new type of battery, such as R & D footsteps. For example, theVinnic batteries are one of them.
The Advantages of Lithium Titanate Batteries
The again recently held "2012 new energy automotive industry and cooperation Summit Forum Project butt Fair mentioned a new type of battery – the outstanding performance of lithium titanate battery. Lithium iron phosphate energy density has been developed to a higher level, and you want to further breakthroughs is the very difficult. Now launched the lithium titanate batteries, and compared with the commonly used silver oxide batteries, it is very stable in use, do not form SEI film; coupled on lithium titanate is potential than lithium metal, is not easy to precipitate lithium dendrite, so it is more secure. Currently, only a small number of enterprises in the use of lithium titanate batteries are using lithium titanate "pure electric buses 10 minute quick charge" According to reports, after a year of operation, over 50 thousand kilometers traveled, charging more than 2,000, the test of Chongqing mountain and a high temperature of 44 degrees Celsius the lithium titanate fever running than phosphate lithium battery is low to around 10 degrees Celsius.
Chinese Financial Supports New Energy Battery Innovation
In order to speed up the process of technological innovation and industrialization of new energy automotive industry, the central government will allocate funds to support the technological innovation of the new energy automotive industry. Yesterday, the Ministry of Finance, the Ministry of Industry, the Ministry of Science and Technology jointly issued a circular, clear the year 2012 the new energy automotive industry technology innovation project reporting conditions. This means that the new energy automotive industry technological innovation projects declared to start.
