The Exuberant Market Demand Of Capacitance Industry Created Opportunities For China
In recent years, due to the price increase of global energy, environmental pressure and production factors, energy conservation and environmental protection concept has already become a popular feeling. The rapid development of solar energy, wind energy, energy saving lamps and lanterns, electric vehicles and hybrid cars, automobile electronics, combination of three nets and other emerging industry, bring new growth of capacitance market and, at the same time, it set the new request for manufactures and suppliers to capacitance components.
The exuberant vitality of traditional aluminum electrolytic capacitor
With the development of science and technology, especially the development of integrated circuit (IC), very large scale integration (VLSI), the sustainable development of the capacitor industry and its existing space was the focus of people’s attention, however, since 1987, global capacitor production has a more than 20% growth every year, make this doubt collapse.
Aluminum electrolytic capacitors have advantages of large capacity per unit volume, electrostatic of large capacity, high specific volume, easy miniaturization, self-healing properties with low price. Practice proves that the capacitor has extremely strong vitality and irreplaceable features. On the one hand because of the appearance of IC some of the capacitors with smaller capacity integrated into the circuit internal. On the other hand, the development of the IC made circuit system greatly improved, causing the electrolytic capacitors were replaced by other capacitors in some of the circuits. However, the power of the IC circuit is always inseparable from electrolytic capacitor. In addition, the improvement of the performance of their own electrolytic capacitor made it can be expanded in its application field.
In recent years, electrolytic capacitor has made breakthrough progress, realized a qualitative leap. Not only its market share does not diminish, its application field is expanded, presented a high growth in many unprecedented opportunities. China’s electronic components industry association information center forecast: in the two years China’s aluminum electrolytic capacitor market scale will remain 5%-9% of the growth rate, but with the government advocates “energy conservation and emission reduction”, frequency conversion technology has been widely used in the national economy. Wind power and photovoltaic power generation as a representative of the green energy field, the rail traffic construction also put forward the great demand to aluminum electrolysis capacitor, these three areas will become the main driving force of electrolytic capacitors industry.
Super capacitor also benefits from the rapid development of new energy industry
Because of the rapid development of new energy industry especially new energy vehicles industry, super capacitor, as core power energy storage equipment, stepped into high speed development stage. The super capacitor is now the most advanced energy storage set. Previous energy storage equipment is made by chemical energy into electric energy, again by chemical energy into electricity with two shifts, which will have energy loss. Super capacitors directly charging and discharging directly, thus the discharge efficiency is as high as 98%. The economic price is bigger, while the cost is only 70% of lead-acid batteries. Super capacitor electric bus with environmental protection, energy saving, low cost advantage performance, has become the best plan of the modernization of public transportation, and at the same time, it is the main force of aerospace, military, as well as the environmental protection.
The current car power battery basically has the following types: the most cheap one is lead-acid batteries, it has heavy pollution, currently only used for battery bike; the cheaper one is NI-MH batteries, and it is expensive and trip mileage is very short; Little bit better is lithium iron phosphate battery, price is more expensive, most of the electric car have been used, and it can realize traveling 100-120 km with a charging, which also need to start the engine hybrid to extend the mileage, but safety risk is bigger; The best is super capacitor power battery. The features of cheap, no maintenance, and 100,000 to 500,000 times recharge cycles will serve as the mainstream of the power battery life.
In addition, earlier this year, finance subsidy policy of our country to new energy vehicle purchase for private has launched, choosing Shanghai, Shenzhen and other five cities as pilot subsidies for individuals to buy new energy vehicles, with plug hybrid vehicle each a supreme allowance of 50000 Yuan; Pure electric vehicle each a supreme allowance of 60000 Yuan, this will be a opportunity for super capacitor further development.
Because major Japanese electrolytic capacitors enterprise such as Nichicon, Rubicon, Chemi-con etc mostly concentrated in Japan Fukushima affected by “3.11” earthquake and the surrounding area, the aluminum factory and raw material power capacitors supply are in shortages, this kind of influence may not be eliminated in the next three to nine months.
Due to market factors, this brings opportunities to Chinese capacitance industry. Original orders in Japan of capacitance flowed into our country, giving China industry many opportunities, China electrolytic capacitors become in short supply. Through the financial crisis in 2010, passive components industry with out of stock gradually matured, and the ability to resist the risk increased. With the gradually accumulated technology and market reserves, China’s manufacturers tried to grasp the market opportunity.
