fastElectric toys spawned rapid charge and discharge Li-ion battery technology
Early polymer battery applications mainly in mobile phones, mp3 and other digital products field. This is because when a great volume of these areas, special requirements (mainly discharge current) is small, so sought after by the early polymer manufacturers. Polymer battery technology development focus in addressing the capacity, circulation and stability, especially in the early inflatable battery problems, led many industries the use of polymer Latitude D610 Battery a long time still at the observation stage. As the technology and processes continue to mature, and now this issue had already been resolved most of the manufacturers.
Video games to promote an extension of battery performance
Toy industry demands on the battery is different from the digital products industries. First, the discharge current is relatively large magnification, the average current of the digital product requirements are not greater than 1C, the vast majority are only asking for no more than 0.5C current. The general use of rechargeable batteries in the toys require at least more than 4C discharge rate, these properties for digital product design in most of the battery can not be realized. Second, in addressing the high-rate discharge performance, the toy manufacturers have begun the performance of some other details of the proposed requirements, such as half an hour, or even 10 minutes of Latitude D620 Battery fast-charge cycle life is more durable, long continued storage of the storage performance (for example, 6 hours), better security properties. According to different requirements of customers, and now manufacturers are in various polymers in different aspects of the details of the performance of their products were extended and developed.
Rapid charge and discharge to promote Toys Update
In order to fast-charge, for example, now has a number of manufacturers have made a lot of efforts in this regard, also made a lot of progress. 1C charge from early and gradually developed to the 2C, 3C or 6C, the following is now the industry is very popular in a Fullriver452026P 130mAh fast charging curve (Source: Manufacturers brochure)
In the 5C's Latitude D800 Battery fast-charge mode, even with constant voltage charge time is only take 25 minutes to remove the constant pressure if the process is also able to charge about 6 minutes into the 60% of capacity. If the charge time for 15 minutes, you can reach 92% charging efficiency. In support of this battery technology can not only enhance the user's convenience, but also can improve the use of the product frequency, speed up the upgrading of products! For example, a toy products, the average consumer would lose re-use 200 times freshness, and then buy a new alternative. Then the 1C charge in the ordinary conditions, only the ability to play four times a day. If the same conditions of use, select 5C & 15 minute quick charge, then the consumer will be able to play at least 10 times or more a day. This role in promoting the development of the industry is self-evident.
Fast charging and discharging battery technology to promote the development of
In this fast-charge the Latitude D810 Battery faster release of products under the conditions of life is also a challenge. Generally speaking, in accordance with the capacity to produce 80% of industry standards, general requirements for electrical toys are about 100 to 300 cycles, medium and large model aircraft batteries are generally only requires 30 to 50 cycles or more. As we all know, quick charge quick release quick release, especially damage to the battery life is very obvious. So in this regard toy rechargeable source requested further increased. Marked in Figure 2 data (battery model with Figure 1) show that, in 2.5C fast charge, 10C (manufacturers nominal 8C) quickly under the conditions of release, the battery life of 200 cycles is still able to maintain in the first 82 % (95/115 × 100%) around! Although the attenuation capacity of the battery showed volatilities, indicating the consistency and stability in the performance of the battery is still not perfect, but it created a precedent of this technology.
To sum up, as a large toy manufacturer, producer of raw materials and the continuous localization of accessory products, will help us a competitive advantage on cost, but also be able to continue to require suppliers to provide more appropriate and more complete design and attempt to shorten product development cycles, enhance the competitiveness of enterprises.
Three painful experience of domestic battery industry,
This year in May, the EU adopted a draft directive batteries, which means that China's export enterprises will be the EU's commitment to expensive batteries battery recycling costs.
In September, lead-acid batteries, mercury oxide battery export tax rebate policy was canceled, so that the cost of increased suffering from troubled worse battery industry. Chinese Journal of Chemistry and Physics of Power Industry Association, said the Secretary-General LIU Yan-long, Latitude D820 Battery companies profit margins are suffering a huge impact, some enterprises are facing a loss.
The pain of raw materials
Learned from the Guangdong Inspection and Quarantine Bureau, China's battery industry is currently facing a serious manner, "internal and external problems."
This year, lead-acid batteries can not be a lack of raw materials of metal lead, nickel prices have begun to have increased significantly. According to insiders, as countries around the world to improve environmental protection requirements, lead is also a gradual increase in production costs, some developed countries have even stopped the production of lead in their own countries, instead, to purchase finished Latitude D830 Battery products in the international market lead to pass on the national environmental pollution, which causes an electrolytic lead prices soared, from 4,500 yuan per ton in 2003 rose to 13,000 yuan per ton in earlier this year.
At the same time, according to business reflects the nickel price from 150,000 yuan per ton last year or so, now risen to nearly 300 thousand yuan per ton. In addition, raw materials, cobalt, natural manganese powder, zinc and other prices rise to varying degrees. As the price of export products is well established with the signing of the contract, raw material prices, the price can not rise, resulting in a "export more, the greater the loss" situation. Domestic battery materials produced fierce competition among enterprises, leading to accumulation of battery materials business in recent years, the low rate of less ability to withstand risks, coupled with the battery manufacturers in international market advantage living in a buyer's market, the domestic Latitude X300 Battery companies falter. Some traditional export large enterprises have had to reduce the volume of exports, in order to reduce losses.
The pain of tax refund
September 14, the State Ministry of Finance jointly issued by five ministries and the "some of the goods on the adjustment of export tax rebate rate and the addition of the processing trade ban catalog notice." The new policy since September 15, 2006 implementation date. According to "Notice" provisions of lead-acid batteries, mercury oxide XPS M140 Battery export tax rebate policy has been canceled, and will be included in the processing trade ban catalog included in the directory processing trade ban of imports of goods should be levied on import tariffs and import taxes .
According to agency statistics, the export tax rebate rate down 1 percentage point each, equivalent to the cost of exports in general trade increased by about 1 percentage point. Experts said the introduction of export tax rebate policy for the distress suffered the negative battery industry, is undoubtedly worse. In the long run, will accelerate the battery industry re-shuffling, a number of competitive small and medium enterprises will be seriously at a loss, or even face closure. According to exporters, the most so that they are worried that the export tax rebate cancellation and production XPS M1210 Battery costs rise, the consequences are most of the overseas buyer to select the target may be transferred to the prices of national and regional comparative advantage, resulting in trade transfer.
Pain barrier
September 26, 2006, the European Union, "Official Gazette" the enactment of new batteries and battery instruction. This means that China exports to the EU in the future not only to meet our demanding battery of mercury, cadmium content requirements, will also assume the expensive recovery costs.
There are manufacturers that the EU has frequently set the "green barrier", has made exports to the EU a substantial increase in the cost of the XPS M1530 Battery. Some SMEs had to because of economic reasons and technical reasons to give up the EU market.
The face of the battery enterprises are facing difficulties, this Zhansi Ming, deputy director of Guangdong Inspection and Quarantine said that enterprises should strengthen the technology, equipment innovation, improve the utilization of raw materials to reduce wastage of resources and reduce raw material increases are a result of an adverse impact on .
China Power Industry Association of Chemistry and Physics, LIU Yan-long Secretary-General also said that the association will actively guide enterprises to deal with tax rebate system reform in order to adjust the advanced business management tools for operational mechanism, and guide enterprises to adjust product mix, diversification of export products to the direction.
And suggested that corporate research recycling of waste XPS M1330 Battery recycling technology, the establishment of offshore recovery system. Many exporters also called on all local governments should be as soon as possible the local support, subsidies and other supporting policies to help the battery companies to survive the temporary difficulties, to create a favorable policy environment to ensure that the battery exports continued healthy development.
