In recent years, due to the increase in global energy, environmental pressures, as well as prices of production factors, the concept of energy saving and environmental protection has gained recognition. The rapid development of solar photovoltaic, wind power, energy-saving lamps, electric vehicles, hybrid vehicles, automotive electronics, triple play and other emerging industries in the capacitor market room to grow at the same time, but also on the capacitive elements and their manufacture, the supplier of the new requirements.
Traditional aluminum electrolytic capacitors have great vitality and
with the scientific and technological development, especially in integrated circuit (IC), the development of very large scale integration (VLSI), the entire capacitor industry sustainability of development, even survival space attentions However, since 1987, the global capacitor production of an annual growth rate of more than 20%, this suspicion proved unfounded. ,
Aluminum electrolytic capacitors have the capacity per unit volume, large capacitance, high hematocrit, easy miniaturization, with self-healing features, low prices, a unique advantage. Practice has proved that the electrolytic capacitor has a strong vitality and irreplaceable. One hand, the emergence of the IC, so that part of the small capacity of the capacitor are integrated to the circuit internal; the other hand, the development of the IC circuit system operating frequency is greatly increased, resulting in the electrolytic capacitors in the part of the circuit is replaced by another capacitor. But the power of the IC circuit part has always been inseparable from the electrolytic capacitors. In addition, electrolytic capacitors improve the performance of its applications can be extended.
In recent years, the electrolytic capacitor has in many ways made considerable breakthrough to achieve a qualitative leap. Not only its market share has not narrowed, on the contrary, its applications are expanding, showing the rapid growth ushered in unprecedented opportunities for development. China Electronic Components Association Information Center predicted: the next two years China’s aluminum electrolytic capacitor size of the market will maintain a growth rate of 5% -9%, but as the national advocate energy saving inverter technology in various fields of national economy more widely used, wind power, photovoltaic power generation, represented by green energy, rail transit construction in full swing on the aluminum electrolytic capacitor huge demand in these three areas will become the main growth of aluminum electrolytic capacitors driving force.
Super capacitor to benefit from the rapid development of new energy industry
due to the new energy industry, especially the rapid development of new energy automotive industry has entered a stage of rapid development as the core power super capacitor energy storage equipment. According to insiders, the super capacitor is the most advanced energy storage devices. Energy storage device from the electrical energy into chemical energy, chemical energy into electricity, twice the transition energy loss, super capacitor charge directly, and then directly discharge, charge and discharge efficiency up to 98%; economic value, cost only 70% of the lead-acid batteries. Super capacitor electric buses to environmentally friendly, energy saving, low-cost advantage performance, has become a modern program of public transport, but also the aerospace, military, and environmental aspects of the new force. Car battery power in
following four categories: most low-grade lead-acid batteries, heavy pollution and the bike is only used for the battery; low profile nickel-metal hydride battery, is expensive, very short mileage, electric not the future of the car; better of lithium iron phosphate batteries, expensive, most electric vehicles are already using, and a single charge driving 100-120km, need to start the gasoline engine hybrid to extend the mileage, but a security risk than ; the best super-capacitor power battery, cheap, maintenance-free, 10 to 50 million times the charge-discharge cycle life, will become the mainstream of the power battery. Have
industry source said, "It is because of the broad market prospects, a growing number of super-power companies are sparing no effort to develop new markets." Can be predicted that good has come of age in supercapacitors. "
In addition, earlier this year financial subsidy policy was officially introduced to China for the private purchase of new energy vehicles, new policy options in five cities including Shanghai and Shenzhen, as a start private purchase of new energy vehicles, subsidies for pilot projects, plug-in hybrid vehicle the maximum subsidy of 50,000 yuan ; pure electric vehicle the maximum subsidy of 60,000 yuan, which will be the opportunity to further develop super-capacitors.
"3.11" earthquake in Japan the impact
capacitor market in China because of Japan’s major aluminum electrolytic capacitors companies Nichicon, the Rubicon, chemi-con are concentrated in the subject to "3.11" earthquake in Japan affected by Fukushima and surrounding areas, the shortage of electricity and raw material supply of the many aluminum electrolytic capacitor factory, and thus indirectly affect the plant production of passive devices, and may not be able to eliminate this effect in the next 3-9 months.
Market factors dictates, contrary to the capacitor industry in China has brought opportunities. China, originally scheduled to have the flow of the capacitance orders in Japan to give the capacitor industry many opportunities, the Chinese aluminum electrolytic capacitors becomes in short supply. We see the aftermath of the financial crisis, the stock in 2010, the passive components industry is gradually mature, and constantly enhance the ability to resist risks. With the gradual accumulation of technology and market reserves, the capacitor manufacturer in China in front of the big event more than a response to the lung, and tried to grasp more market opportunities brought about by the component substitution; Distributor is no longer for the lack of goods, delivery extension sad do not show, in order to expand the product line, finishing the business model to avoid the risk is very much at home. |
