The best battery tips and news

33% of battery failure, Amoi lithium batteries “serious problem”

Learned from the Shanghai Quality and Technical Supervision yesterday in its latest mobile phone battery monitor checks in the city of production and sales of non-original battery is poor overall quality of the sample pass rate was 66.7%, security needs to be improved. Among them, Amoi Electronics Co., Ltd., Shenzhen Super Power Electronic Co., Ltd, Song Xun Da Zhong Ke Electronic (Shenzhen) Co., Ltd was ordered to rectification.

Non-original mobile phone batteries, also known as “compatible battery.” As the price of the same specifications than the original battery cheap, non-original batteries currently on the market share is increasing. The Shanghai quality and technology supervision department had taken 15 different cell phone batteries, of which 10 types of compliance, 5 failed.

Safety non-original mobile phone batteries failed the outstanding quality. Testing, the nominal power of Shenzhen Super Electronic Co., Ltd production of “super-power links” lithium-ion battery, Amoi Electronics Co., Ltd. Production “Amoi” lithium polymer rechargeable battery and Song Xun Da Zhong Ke Electronic ( Shenzhen) Co., Ltd production of “TSD” lithium batteries, the thermal shock test in the process of explosion determined by regulators as a “serious problem of quality products.”

In addition, some non-original mobile phone batteries “standby current”, “current call” and other indicators of substandard, the direct result of the standby time, talk time was shortened.

Experts pointed out that mobile phone batteries on the market price difference between the poor, the quality varies greatly. From a security point of view, genuine mobile phone batteries installed within the general over-current protection device, such as abnormal in the case of short circuit can be automatically cut off the circuit, to avoid damage the device. If the charging process, the cell phone batteries severe heat, smoke and other phenomena, we show that the battery is fake.

Fuel Cell Development and Material and technological progress

Fuel cell development depends on the material and technological progress

Securities by the financial Web site co-sponsored work, “China’s energy reform and investment opportunities Forum” on May 15 Han Chinese in Beijing International Hotel. In the “search for new energy crown jewel” round-table discussion, Beijing speeding executive vice president of Green Energy Co., said Zhang Lifang, the future development of the fuel cell industry will mainly depend on the material technology.

Zhang Lifang introduced is actually an electrochemical fuel cell generator, the energy conversion efficiency is relatively high, it is not a general understanding of the concept of the battery. It later by hydrogen catalyst, hydrogen and oxygen combined with the process of the formation of the electronic conduction current after the power out, such a process, so it is not a power storage device, called the fuel cell is translated from abroad results. For example, in car use is used as a standby power supply, which were used in the family of small power stations. Just pass the gas, outside the current load will automatically have power, no will power when the load, it will not consume hydrogen, fuel cells this respect there are indeed many advantages.

Zhang Lifang that no matter what the battery cell, consistency difficult to achieve. -Powered battery pack when the consistency of each single cell is not good, does affect the battery pack. Therefore, the impact of this will bring bad battery cause problems quickly, it will damage the battery. But also in the battery management is also a very complicated matter, it is not easy to do, in the use of the process do exist some problems.
Zhang Lifang that the fuel cell does now, there are some problems, such as fuel cells cost too high. Proton exchange membrane, catalyst, carbon, bipolar plate, these four materials, two are dependent on imports, the cost of fuel cell has been cut down. For example, although the bipolar plate 500 from 10 years ago, a dollar is now down to only tens of dollars, price down more than 10 times, but still expensive. Therefore, the fuel cell industry also depends on the material and technological progress, there is no progress in materials technology, fuel cell industry development is also very difficult.

Gas PK New energy battery

At present, China should stimulate domestic demand economy is entering a stage of development to stimulate the economy, I believe that natural gas and natural gas utility in the country’s economy can not be underestimated consumer products. Therefore, as the industrial, civilian necessities East Energy (002,221), in particular the transformation of liquefied petroleum gas vehicles, natural gas sales will increase, in order to reduce pollution in many big cities, buses have to use LPG cars. Today, many industries are in the economic environment, natural gas, consumer products market, listed companies will be in hot pursuit of large organizations, coupled with new energy battery is still in the experimental stage, there is officially put into operation from a long distance. Thus, the present substitute for gasoline vehicles can only be natural gas, rather than new energy battery. Therefore, in the immediate consumer market, natural gas will undoubtedly reap the opportunities, I believe that natural gas will be short-term PK new energy battery.

One bright spot about 3 yuan Tung Wah Group of energy that there has been an issue price below the market victimizes

The 5600 issue of A shares of the company shares, the total share capital after the release of 22200 shares. Issue price of 5.69 yuan, while the current stock price was around 3 yuan, the group energy that there has been an issue price below the market victimizes the suspect. The largest shareholder of the company East Petroleum (Yangtze River) Ltd. shares held by 8134, representing the total share capital after the release of 36.64%. Company in east China is the largest high-quality industrial gas supplier. 2006 industrial gas sales accounted for more than 90% of the total. Chinese imports for many years the company occupied more than LPG market share of 4.8%, imports of liquefied gas for three consecutive years ranked number seven before.

Highlight Second Unit 2007, gross profit 259.97 yuan / ton, an increase of 44.30%.

Rising corporate profits because the company spent 2005 in West-East natural gas produced after replacement of the (company sales strategy in 2005 to parity in 2006, is also very limited price increase), to start their own price adjustment and improve the pricing ability to actively adjust the customer while the company structure, to improve margins by optimizing customer; units of 2007, gross profit 259.97 yuan / ton, an increase of 44.30%. Our analysis: the company’s industrial gas business profit model is then further imported LPG domestic wholesale, retail, the role of traders in the middle of the decision on the downstream face of the company’s bargaining power is not high, the price to increase margins by improving the limited space .

Bright future is expected in three liquefied petroleum gas vehicles, the field of chemical raw materials breakthrough.

Imports of liquefied petroleum gas industry gradually warmer. Imports of liquefied gas is mainly used for three main areas: high-quality industrial gas, liquefied petroleum gas vehicles, chemical raw materials. From a gas perspective, there is the main alternative to natural gas in short supply and prices will continue to rise, which makes imports of liquefied petroleum gas industry is expected to bottom out the previous two years; the same time, imports of liquefied gas by virtue of its environmental advantages, price advantages, the future is also expected to liquefaction gas cars, the field of chemical raw materials breakthrough.

Lithium Battery and Hybrid cars

The New York Mercantile Exchange, August crude oil futures prices for delivery in July 3 145 U.S. dollars a barrel, the highest recorded. In this week, OPEC weekly average oil prices to new highs. In fact, for some time, high oil prices and the resulting series of political and economic and social issues deeply hurt the car manufacturer. In the United States, the three auto makers have cut production of large pickup trucks, SUV, increase energy-saving small cars or crossovers. However, changing the structure of existing products, while car manufacturers have already “obvious”: before you have to master the technology of alternative energy vehicles.

“Battery is the core issue.” General Motors R & D lab materials laboratory director Mark? Sheet Mubarak said. Have been successful experiences with a certain market hybrid car, the battery technology in deciding the fate of the car key. It is understood that currently includes the Toyota Prius (configuration parameters Gallery) models, including hybrid vehicles use nickel-metal hydride batteries. And the battery technology itself has limitations. Remove the price factors, on the one hand, the decision by the material limits the size of storage capacity, lack of capacity Ni-MH battery life, on the other hand, it can not be extrapolated charging.

Li-ion battery is a high voltage, charge and discharge, long life, fast charging, self-discharge rate, wide operating temperature range, etc., have become the most cars and parts enterprises and the main direction of choice. Data show that, compared to nickel-metal hydride batteries, hybrid electric vehicles using lithium batteries can make the weight decreased by 40% to 50% and the volume reduced by 20% to 30%, energy efficiency has improved to some extent. Optimistic forecast said that in the near future, the vehicle will decrease the cost of lithium batteries to nickel-metal hydride battery 2 / 3.
