Lead-acid batteries have great vitality and look forward to Tian Neng with greater development

October 18, 2009, the Chinese Academy of Engineering, Chinese Military Power Chemical Honorary Director of Research and Development Center Major General Yang Yusheng days to visit and inspect the base of the Group of a new battery, and with day to the Chairman of days Zhang board,  laptop battery rechargeable  served on the China New Energy Battery exchange and development prospects were discussed days Group Vice President Yuanling Yang, deputy chief engineer of a fu, Investment Director, Zhi -Kun Wang, and a famous Chinese expert Dr. Cao electrochemical Gaoping join the discussion. Academician Yang believes that leaving the country, the national interest and economic development, to consider the development of new energy battery China. The outlook for the future development of lithium batteries good, but the main problem is the battery safety and compliance rates, lead acid batteries in electric vehicles and a lot to offer in the field of batteries The key is to continue to make technological progress and environmental protection.
Lead acid batteries have great vitality and there is a new
Academician Yang explained that 150 years of experience in lead acid battery that does not weaken the nickel - cadmium batteries, nickel - hydride batteries,  dell latitude d610 battery,dell latitude d620 battery lithium-ion batteries and other batteries are listed several decades, yet firmly hold the majority market share, China Electric Bicycle produce nearly 20 million, mostly equipped with lead acid batteries, the world a variety of diesel locomotives, each is using a lead battery acid, It is no coincidence. In addition to its technology is mature, inexpensive and low network, high security and other traditional activities pending substantive, and it has developed in recent years in the competition are closely linked to many new technologies such as three-dimensional and two - three-dimensional structure of electrodes and the tube sealed whole, and so was the new structure, the use of new lead alloy electrode can promote a gradual increase of the specific energy and cycle life can up to 4500 times (70% DOD). Lead-acid “super battery” is also one of them the latest technology. Therefore,  hp 338794-001 battery,hp 361742-001 battery lead acid batteries are not exceeded, lead acid batteries with new technologies.
What a lead-acid “super batteries”? The so-called lead-acid “super batteries” UltraBattery is the super-capacitors in parallel with the use of lead acid batteries (may be called “out and”), the development as ” domestic and “(lead-acid battery with a supercapacitor combination carbon), is to electric double layer capacitors of high specific power, the advantages long life integration in lead acid batteries, while maintaining “outside and” increase the power, sony pcga-bp2t battery,sony pcga-bp2v battery  extend battery life at the bottom of simplifying the circuit can improve the specific energy, and reduce the total cost. It was a great development of electric bicycles from China and electric vehicles are being launched, you will have a huge economic and social benefits. Lead-acid “cell” super There are two main technologies, one for sulfuric acid electrolytic capacitors, high-performance materials, carbon and the second capacitor anode of carbon and lead compounds.
In combination with a variety of new technologies, lead-acid energy density of the battery can be increased to 60-80wh/kg, power can be increased to 600-700W, which has about Li-ion battery of technical indicators.
863 plan should encourage the technological development of lead acid batteries
Recently, the U. S. President Barack Obama has announced that 2.4 billion dollars allocated to support 48 U.S. development project, “the next generation of batteries and electric vehicle production, including lead-acid battery, ibm thinkpad r51 battery,ibm thinkpad r52 battery  arranged respectively the 34.3 million U.S. dollars and 32.5 million U.S. dollars to support the two companies led the development of “cells” super project. Remarkably, the plan made no mention of hydrogen and fuel cells .
YANG Yu-sheng academy called a “monk reciting sutras,” may be moved to China “Buddha” without more lead acid batteries bias, it should be strong support for lead acid batteries. Academician Yang suggested that the support of China 863 plan must be clear for lead-acid “super batteries”, not hesitation. To this end, he suggested the government to produce 45 million yuan (equivalent to U.S. States, 1 / 10), supporting 2.3-production - The research portfolio, and corporate matching funds of 1:1, with two years to develop lead-acid “Super Battery” and carbon capacitor and formed a certain production capacity to scale. It is also to solve the financial crisis by encouraging domestic demand, one of the best shots.
Lithium is the future direction of development, but the technology still needs to be improved
Academician Yang that lithium is a good direction, but he must first resolve security and compliance rates.
The safety of lithium has been the fear everyone. 2009 cell phone battery exploded in China, seven times, three people died, technically speaking, cell phone batteries lithium is relatively simple, it is not in series of parallel problems. It is understood that energy lithium batteries cell phone is probably 2WH, according to international statistics, apple a1185 battery,apple m8403 battery  the probability of explosion is 1 / 10000000, while a bus is probably the energy of lithium batteries 200,000 WH If the number of hours and mobile phones in accordance with Watts lithium battery compared to the probability of explosion in May or 1%, it can not be ignored. Li-ion battery industry in order to truly solve the problems of battery safety, otherwise the consequences would be unthinkable. At the end is very important or important to the security industry people should pay attention.
The second is the qualified rate of lithium batteries. In addition to large-capacity lithium-ion battery technology to improve but also further improve the level of faith.
Pure electric vehicles for the most energy saving emission reduction
The bottleneck is the development of electric vehicle concept, rather than just technology. Different types of electric vehicles, the biggest advantage of pure electric vehicles: First, do not have oil, 1 million pure electric cars to replace gasoline per day, 10,000 tons, the second is free Pollution; third the total cost (purchase price + energy prices), it may be lower than cars of fuel; 4 is a simple structure, no paved roads and waterways, use, convenience of maintenance, May 5 battery be used at night cheap “Valley Electric” and ready-to-conductor line grid, both to promote the “Valley Electric” (mainly nuclear and wind energy ) to the power grid, distributed peak shaving “, but also save a lot of funding for the construction of the station energy storage power.
Strides in China should give priority to the development of a single charge can travel 150-200 miles of pure electric vehicles.
In addition, applied to a variety of electric propulsion of vehicles of room for development, all types of cells “each party can and fair competition.”
Lead acid batteries in the field of new energy-storage energy scale has the advantage
On the energy development of new China, Academician Yang stressed that the size of lead-acid battery energy storage in the field of competitive advantage. In the field batteries of new storage of energy,  dell y9943 battery,dell fk890 battery,dell gk479 battery which the industry has come a long cycle life of lead acid batteries are used for testing power storage system. The system with the entire power system connected to a peak operation. System test energy storage, three units were the maximum power of 100 kilowatts, 100 kilowatts, 400 kilowatts, two and a half years of continuous operation, no drop in battery voltage, the voltage difference between the increase in issues such as the system works well. Identified practice lead acid battery power system storage.
Meanwhile, development of new energy storage batteries must consider the cost and life expectancy, stable performance, lead acid batteries at low prices. China Research Institute of Chemical Defense Chemical Military Power Research and Development Center has studied the decade military battery, has accumulated a battery needs evidence, research in general, the experience of technological development, with particular attention to the development of technology large scale energy storage in batteries, especially lead-acid batteries recommended in demand in this area.
The industry lead acid battery should pay attention to prevention and control of lead contamination
There comes a lead acid batteries, lead is often said that there must be problems of environmental pollution. In fact, the lead acid battery is the highest recovery rates of all cell types, but also lead to the production process of large companies was also strictly controlled. To effectively solve the smelting of lead mining and recycling of used batteries in the lead contamination and acid, as long as a serious step and responsible departments of environmental protection, enterprises attach importance to implementing measures to protect the environment, the problem is not difficult to solve.
Currently lead battery industry to strive for from a lead mine,  dell inspiron 1420 battery,dell inspiron 1501 batterybattery production and recycling of old batteries fully enclosed operation, it can reduce lead pollution. Why do not pollute the environmental concerns of nuclear energy, because the raw materials of nuclear power uranium mining to recycling, the process of protecting the environment are thriving. Lead-acid battery chain industry can learn from the experience of producing nuclear energy.
Two new lead-acid “cell” within the super much less lead than the existing lead-acid batteries, longer life, but also reduce the workload of regeneration, which are of direct benefit to reduce lead contamination .
Lead-acid battery production equipment for the localization
Finally, Academician Yang spoke about the location of equipment lead-acid battery problem. He said that now the new lead-acid batteries (eg, tubular cells) and the former battery recycling equipment business, many use imported equipment. Expensive imported equipment, preventing large-scale popularization and application. Companies battery China imported production equipment, we must consider the location of the equipment as soon as possible. Import of equipment at home is a good opportunity, but also promotes the battery industry in China opportunities for technological advancement. Equipment prices down, companies can not use the advanced equipment pollution. Those who hope that China will work together to lead acid battery industry, from exploration to recycling old batteries throughout the process as soon as possible to plan and promote the location of the equipment.
