1800 Italian physicist Alessandro V invented the world's first battery. Since then, people come up with a variety of new battery, but the basic principle of operation of all batteries is the same: the use of different materials between chemical reaction to store and release energy. The world's first rechargeable battery, lead acid battery that is, by the French physicist Gusi Dun Plant in 1859 invented the .19 end of the century Europe and the United Apple A1185 Battery led the major developed countries of the electrification process People began to research batteries, such as its use in cable, flashlight and back-up energy. But the biggest piece of the market may still be in the tram area.

Origin of rechargeable batteries in the past

In the late 19th to early 20th century, the battery-driven tram was a common city street landscape. The reason is that the tram little noise, but also do not emit toxic gases. But in travel, the tram has been defective . to 1912, with the electric starter of the invention, with gasoline internal combustion engine vehicles on the historical stage, the tram followed the fate of being abandoned.

Nickel-cadmium battery in about 1900, appeared, which use more energy demand on the occasion. And, like lead-acid battery, nickel-cadmium battery in use, easier to produce chemicals, especially in the case of over-charging. In the last century the late 40s, the German engineer George Newman by adjusting the chemical composition of rechargeable batteries to solve this problem, so sealed rechargeable batteries become a reality. From the 20th century, 60's, the application of nickel-cadmium battery growing, as such electric shavers and small appliances such as electric toothbrushes to power.

Most of the time in the 20th century, lead-acid batteries and nickel-cadmium battery dominates the rechargeable battery market, these two being the use of a battery so far. Despite the fact that the stored energy per unit volume is concerned, they can not be compared with new battery , but the cost is concerned, they are extremely cost-effective. Today almost all the cars start the engine comes from a small lead-acid batteries to provide pulses of electrical Dell Inspiron 6400 Battery. They are also used in large-scale back-up energy system and of the global charge nearly half of the battery market. in aircraft and trains, the use of nickel-cadmium battery as an emergency backup power sources.

New battery era

In the past two decades, two new rechargeable battery started budding in the market. Twice the energy per unit volume stored in lead-acid batteries in nickel metal hydride batteries in 1989 entered the market. 90 in the last century, nickel metal hydride batteries as a portable electronic products the best driver of energy, it also replace the nickel-cadmium batteries, be applied in many fields. Toyota introduced the new 1997 Prius hybrid car is also used in nickel-metal hydride battery .

Today's mobile phones and handheld computers are still widely used cobalt oxide battery cathode materials. Zhelei rechargeable batteries are also starting to use in the car, such as Tesla Motors sports car. But High chemical activity of cobalt oxide and costly, large Most experts believe that it is inappropriate for widespread use in hybrid vehicles or pure electric vehicles.

So the researchers started trying another way.'s Michigan-based Compact Power Inc. has begun to replace the batteries with manganese cobalt, manganese because of lower cost and more stable at high temperature. The bad news is, as elements will be dissolved manganese In the electrolyte, have a shorter lifespan. However, the U.S. Argonne National Laboratory senior scientist Maikeersa Kerry believes that the manganese and other elements, such as nickel and cobalt, mixed up and use to solve these problems.

In 1997, U.S. scientists said, is expected to use the new iron phosphate as cathode materials. Compared to cobalt oxide, iron phosphate has low price, safety and environment protection. But the drawback is the low energy density, electrical conductivity is poor, thus affecting electric storage battery, discharge performance. Later, in 2002 researchers at Massachusetts Institute of Technology published a paper in a number of iron phosphate doped aluminum, Dell Latitude D610 Battery and zirconium can greatly improve its conductivity. However, the results there are still some open to question.

Iron phosphate battery technology currently in commercial use by several companies, the United States and Canada A123 Systems Inc. Phostech Lithium in them. Phostech Lithium production and sales company has a patent based on Dr. Gudengnafu the exclusive right of battery materials. However, while both companies to compete for market share, but the result is still very unpredictable, because it will also involve issues of patent infringement.

In recent years, China's electricity demand continues to rise, especially including Zhejiang Province, East China power grid, including areas of power consumption in China has become the largest area has the highest electricity demand growth. With the increasing demand for electricity, power generation capacity to gradually increase, while supply for the stability of investment in transmission and distribution are also growing. Among them, the demand for distribution transformers has continued to grow, demand for the Chinese market in 2007 exceeded 210 billion yen, or about 4.5 times of Japan.

Hitachi Industrial Equipment is Japan's leading manufacturer of transformers, amorphous alloy produced by high energy efficiency transformers. The transformer station can transmit high-voltage conversion for the safe and reliable low-voltage, wrapped in the core part of the power sensor is used in amorphous alloys, which can significantly reduce the standby power received results. As the transformers are generally used for 30 years, is quite a long time, therefore, objectively speaking, the energy performance of transformers made strict requirements. China's demand for amorphous transformers rising.

Hitachi Industrial Equipment The top Chinese manufacturer of power distribution transformers - Hangzhou Qianjiang Electric Group, jointly established the Hitachi money call (Hangzhou) as an amorphous transformer transformer production, sales and service base, began to formally enter the Chinese distribution transformer market. Hitachi call (Hangzhou) transformer in November 2009 in Hangzhou, Zhejiang, China Xingang Town, Xiaoshan District, Hom village started to build a new plant in or about to 12,000 square meters, is expected to be launched in spring 2010 non- crystalline core of the transformer and the core components of mass production. Sales of the product will be Hangzhou Qianjiang Electric Group and Hitachi (China) are jointly responsible. Hitachi Industrial Equipment with the Hangzhou Qianjiang Electric Group in the production and sale of two cooperation, gradually expanding in China, amorphous variable electrical cause, and strive to make the Chinese market in 2014, sales of 50 billion yen (about 370 million yuan ).
