After more than a year research and development, Qidong City, Glencore Solar’s high performance environmentally friendly solar energy network beacon light yesterday by the Urban Ocean and Fishery Board for approval, in the city promoting the use of marine fishing vessels.
Fan Zhang marine fishing nets and drift nets need to use net operating beacon light illumination, display operating range, to prevent the wound. According to experts, old-fashioned network beacon light battery for 2-3 days once a boat nets need to replace a inspiron 1420 battery , inspiron 1501 battery 45, the average per vessel per year over the use of batteries in 2000. The city’s nearly 400 sail net, net fishing vessels of more than 200 boats a year for fishing the ocean dumping of used batteries up to about 1.5 million.
Last year, the City of marine and fisheries departments in the nation’s coastal fishing launched the first use of waste battery recycling. Radically reduced from used batteries for fishing on the marine environment, pollution, development of high-performance environment-friendly solar energy network beacon light to replace the original old-fashioned network beacon light, it is imperative.
Net new type of solar beacon light to solar energy into electricity, can guarantee 10 consecutive rainy days at the normal light. Such as the city’s comprehensive promotion of fishing vessels will be able to significantly reduce pollution, fishing with used batteries.
Expert: NB cell phone use lithium-ion batteries need to re-design of insecurity
Japan’s Tokyo University of Technology, Professor Masataka Wakihara recently inspiron 1520 battery , inspiron 1521 battery said that laptops and cell phones use lithium-ion batteries the underlying technology is unsafe, need to consider re-design.
Wakihara said that most laptops and cell phones use lithium-ion batteries are potentially dangerous underlying technologies, and thus fail to meet the standards required by its mission. Therefore, the need for design improvements.
Wakihara also said: "In this regard, the battery manufacturer is still in the learning phase, as manufacturing technology is not mature enough. The problem is, the current lithium-ion battery there is a fundamental flaw in the design, to avoid security problems, they must be thoroughly changes in manufacturing methods. "
Wakihara lithium-ion battery will be described as a "dangerous power box." Wakihara point of view also supported by the Japan Industrial Technology Association, the National Senior (NIAIS) battery Kuniaki Tatsumi, head of research support. Tatsumi said: "The battery manufacturers very little attention to the latitude x1 battery , latitude x200 battery , latitude X300 battery safety of the battery design."
Last Tuesday, Nokia had announced, because of overheating risks, will be within the framework of the global recall of 46 million mobile phone batteries affected more than 50 models of mobile phone models. Saturday, Indian users Rajesh Shastri also disclosed that he used the Samsung "schn 356" mobile phone exploded unexpectedly.
In fact, since last year’s Sony laptop battery fire incident took place, the people of lithium-ion batteries are also increasingly concerned about the safety. But before that, experts have been saying, lithium-ion battery is still the best and safest choice.
Notebook PC, mobile phones, digital cameras, the industry groups to develop safety standards for lithium batteries
In order to develop safety standards for lithium batteries, notebook computers, mobile phones, digital cameras, the relevant industry groups are currently carrying out business cooperation. Electronics and Information Technology Industries Association (JEITA), battery industry will be (BAJ), information and communication network Industry Association (CIAJ), imaging equipment industry will be (CIPA) and other four groups have begun to cooperate in establishing the safe use of Li-ion latitude d820 battery , latitude d830 battery technology standards. Since last year, lithium batteries overheating and rupture of the accident, abnormal frequency, for which industry groups will cooperate to develop safety standards, to eliminate concerns about consumer batteries.
For the safe use of lithium batteries, JEITA and BAJ have been working to develop a "safe use of notebook PC batteries Manual." The manual will be 4 groups estimate that as a basis for discussion. The newly established security standards are expected in the future will be the JIS specifications, and will declare IEC and other international specifications.
At present, the economy, Trade and Industry is considering lithium batteries designated as "Consumer Product Safety Act of living" (Consumer Security Law) and specific products, and said it would help the industry groups to develop technical standards. Four groups to develop safety standards for consumer safety law will be discussed in reference to the progress of the implementation.
August 27, 2007 issue of "Nikkei Electronics" book published on the JEITA develop safety standards for lithium-ion batteries reported.
A playground for the Swiss Kyocera solar modules installed generating capacity of 1.347MW
Kyocera declared to be a football stadium in Bern, Switzerland, the company latitude d510 battery , latitude d520 battery , latitude d600 battery installed solar power generation system. The system’s generating capacity 1.347MW, "installation of the system in the stadium, is the world’s largest class" (Kyocera).
The stadium renovation in 2005, has installed solar power generation system. The original system has 5122 solar cell modules, power generation capacity of 850kW. Kyocera began in April 2007 the project, for an increase of 2808 modules, bringing the total generating capacity reached 1.347MW.
Recently, countries around the world are gradually installing solar battery module for the stadium. The main venue for the 2008 Beijing Olympic "Bird’s Nest" is currently installed generating capacity is roughly equivalent to 100kW of solar battery module, the module from China’s largest solar cell maker Suntech Power Holdings (SunTech Power Holding) manufacturing. In June 2007, the United States Major League Baseball’s San Francisco Giants as the team’s home – the U.S. city of San Francisco baseball stadium "AT & T Park" install 590 Sharp solar battery module manufacturing, power generation capacity of 122kW.
New silicon nanoparticles enhance performance of solar cells latitude d410 battery , latitude d420 battery
Scientists have been working to find better materials and methods to create high-performance solar cells. U.S. scientists, a new study found that in silicon solar cells formed on the surface layer of silicon nanoparticle films can enhance the ability of its energy conversion and reduce the battery’s own heat and prolong life. Relevant papers will be published in "Applied Physics Letters" (Applied Physics Letters) on.
The study was conducted by physicists at the University of Illinois Munir Nayfeh leadership, mainly targeted at the ultra-violet absorption and transformation. In terms of traditional solar cells, ultraviolet light leaking out of line either directly or by absorption of silicon devices, but it is converted into heat instead of electricity, which may affect the service life. In 2004, published in the "Photonics Technology Letters" (Photonics Technology Letters) in a study, Nayfeh confirmed that the UV lines with the appropriate nano-scale particles effectively combined to produce electricity.
In order to achieve practical results, Nayfeh and his colleagues conducted a new study. They first use its own developed a proprietary technology to larger silicon switch is made of discrete nano-scale particles, they will be issued in different colors of fluorescence. Then, the researchers of these inspiron e1505 battery , inspiron e1705 battery particles dispersed in isopropyl alcohol and wipe the surface of the solar cell. When the alcohol evaporates, the surface of the battery will eventually form a tight layer of nano-granular films.
The researchers found that if the solar cells covering the surface is the thickness of 1 nm blue fluorescent nano-particles thin-film, the entire cell will be able to transform more than 60% of the UV lines, but the visible light, the conversion rate of increase less than 3%. However, if the battery is the thickness of the surface covered by 285 nm red fluorescent particle film, then the ultraviolet ray can increase the conversion rate of 67%, while the enhancement of visible light can reach 10%.
Nayfeh that the performance of solar cells such improvements should be more attributed to the improvement of the battery voltage rather than current. He said, "Our study conclusions indicate that charge transfer within the thin film and nano-particle interface, the importance of the amendment."
Nayfeh said that the new coating process can easily incorporated into the current solar cell manufacturing process, while the costs are not an additional increase.
Universal 15-year lithium battery replacement into the plight of inspiron b120 battery , inspiron b130 battery , inspiron e1405 battery
Sony laptop battery recall incident a year later, a similar incident once again plagued Japanese home appliance businesses, the protagonist of this incident is Matsushita Electric Industrial Co., were recalled product is the cell phone lithium battery, this incident also shows that the battery industry is facing a The enormous challenge.
Recalled the most number of record industry’s
Nokia Tuesday announced that part of the Matsushita-made lithium-ion batteries overheating problems, the company will take the initiative to recall these products and for the user to replace the battery, it is learned, and the recall of events up to 46 million mobile phone. It is not clear that the company would recall and replace the number of batteries, but the number of recalled Sony batteries are projected to more than four times higher than the incident has become the industry’s largest battery recall incident, together.
Since August last year, Dell announced that Sony held a large-scale production for notebook computer lithium-ion batteries, the battery industry has been plagued by such incidents. Almost all the major computer makers have announced and recall of Sony laptop batteries, while Sanyo inspiron 9300 battery , inspiron 9400 battery Electric has recalled over mobile phone batteries and notebook batteries.
Battery recalls continue to occur on the one hand reflects the business-to-consumers more prudent and responsible attitude on the other hand also shows that the battery there are still many problems in production. Rechargeable lithium batteries in the past 15 years has been a laptop computer and cell phone industry, one important factor in the rapid development of lithium batteries is relatively cheap, light weight, environmental performance is good, much better than nickel-chromium batteries.
On the other hand, lithium battery current generated by larger, more complex manufacturing processes, heat and even easier to overheat, short circuit occurs when the consequences are more serious. Last year, some Sony laptop battery fire incidents have occurred. The recall Nokia Panasonic lithium battery allegedly occurred because the battery charger overheating.
It hard to recall the aftermath of the incident
Mobile phone industry and the notebook computer industry’s rapid development has inspiron 6000 battery exceeded the pace of development of battery technology, product features but also increasingly improved battery performance higher and higher requirements.
Lithium battery incidents occur frequently prompted some manufacturers to take a more cautious attitude. Toyota hybrid vehicle delay in the use of lithium battery plan. Nevertheless, industry experts still believe that despite the limitations of lithium batteries, but in the foreseeable future, it is still the most practical battery technology.
Sony announced this week that the company will spend 97.6 million U.S. dollars in Singapore to build a cell phone battery manufacturing plant in order to consolidate its market share. The plant will use more advanced lithium-ion polymer technology, the factory is expected to be operational by August next year, the initial monthly production capacity will reach 1 million by 2010 will reach eight million. Toshiba’s ongoing efforts to develop alternative energy technologies, such as fuel cells, this battery does not use chemicals, but the battery for commercial still have a long way to go.
Panasonic is currently the world’s four largest manufacturers of lithium batteries, the company said its the battery problem is generated in the manufacturing process. When used with an insulating layer to prevent short circuit damage occurs when the overheating arises. Nokia said that so far, Panasonic lithium battery overheating problem caused by only 100 cases were reported, but no serious injuries. However, Nokia will continue to take preventive measures to replace all the inspiron 1525 battery , inspiron 1526 battery , inspiron 1545 battery production date of December 2005 and November 2006 between the same origin as the Osaka battery.
