1800 Italian physicist Alessandro invented the world's first one-volt battery compaq Presario M2000 battery(compaq m2000 battery). Since then, people have developed a variety of new batteries, but all the basic operation of the battery is the same principle: the use of different materials between the chemical reaction to store and release energy. The world's first rechargeable battery that is lead-acid batteries,贾斯顿普兰特by the French physicist, invented by .19 at the end of the century in 1859 the major developed countries of the electrification process in Europe and the United States have encouraged people to research batteries, their use in areas such as 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, from battery-powered Compaq Presario V2000 battery(compaq v2000 battery) tram was the city streets a common landscape. The reason is that the tram little noise, but also do not emit toxic gases. But in itinerary, the train has always been there defect. By 1912, with the electric starter of the invention, with internal combustion gasoline-powered cars onto the scene, the tram followed the fate of being abandoned.
Ni-Cd rechargeable batteries in about 1900, came, which make more use of the energy demand is on the occasion. With the same lead-acid batteries, nickel cadmium batteries prone to the use of chemical gas, especially in the case of over-charging. In the last century 40 end of the decade, the German engineer Qiaozhiniuman by adjusting the chemical composition of rechargeable batteries to resolve this problem, making Sealed rechargeable batteries become a reality. 60 years from the 20th century, the nickel-cadmium batteries expanding the scope of application, in order to such as electric shavers and Hp pavillion zx5000 battery(Hp zx5000 battery) small appliances such as electric toothbrushes provide the impetus.
In the 20th century, most of the time, lead-acid batteries and nickel-cadmium battery dominates the rechargeable battery market, which is still being two kinds of people to use the battery. Despite the fact that the stored energy per unit volume is concerned, they can not when compared with the new battery , but the cost is concerned, they are extremely cost-effective. Today, almost all the cars start the engine comes from a small group of lead-acid batteries to provide pulses of electrical energy. They are also used in large-scale back-up energy systems, and of the global charge nearly half of the battery market. in aircraft and trains, people use nickel-cadmium batteries as an emergency backup Hp PP2200 battery power source.
New battery era
In the past two decades, two new types of rechargeable batteries began to emerge in the market. Twice as much energy per unit volume stored in lead-acid batteries in nickel metal hydride batteries in 1989 began to enter the market. In the last century 90's, nickel metal hydride batteries for portable electronic products became the best driver of energy, it also to replace the nickel-cadmium batteries, be applied in many fields. Toyota introduced the new 1997 Prius hybrid vehicle is also used in nickel-metal hydride batteries .
Today's mobile phones and handheld computers are still widely used cobalt oxide battery cathode material for batteries. Such rechargeable Hp Pavilion dv2000 battery(Hp dv2000 battery) batteries have begun to use in the car, such as the Tesla Motors sports car. But because of high chemical activity of cobalt oxide and costly, large Most experts believe that it is not suitable for widespread use in hybrid cars or pure electric vehicles.
So researchers have begun to try to open a new path. Headquartered in Michigan, Compact Power companies have begun to replace the battery with manganese in cobalt, manganese because of lower cost and more stable performance at high temperature. The bad news is that, due to manganese would be dissolved in the electrolyte, have a shorter life expectancy. However, the U.S. senior scientist at Argonne National Laboratory Michael Thackeray that will be manganese and other Hp HSTNN-LB31 battery elements, such as nickel and cobalt, mixed-up and use to solve these problems.
In 1997, U.S. scientists say is expected to use the iron phosphate batteries as a new cathode material. Compared with cobalt oxide, iron phosphate with a low price, safety and environmental protection advantages. But its drawback is that the energy density, low conductivity is poor, thus affecting the electrical storage battery, discharge performance. Later, in 2002 researchers at Massachusetts Institute of Technology published papers said that in a number of iron phosphate doped aluminum, niobium, zirconium elements can greatly improve their conductive properties. However, the The results Hp EV088AA battery are still some open to question.
Iron phosphate battery technology is currently being put into commercial use, several companies, the United States and Canada A123 Systems Inc. Phostech Lithium in which. Phostech Lithium company has the production and sale of a patent based on the ancient, Dr. Deng Nafu the exclusive right of battery materials . However, while both companies to compete for market share, but the result still hangs in the balance, because of which also involves patent infringement and other issues.
