By University Materials Research Institute Hill research team led by Professor Arthur transform one into the glass industry has been widely used, known as method of magnetron sputtering (magnetron sputter) material and deposition technology to create a selenide copper-indium (CIS) selenide and copper indium gallium (CIGS) cells and thin-film solar.

The group received an additional year of education fund Joule Center to continue with North West manufacturer General vacuum research and development.

Note Professor Hill copper-selenide Indium (CIS) selenide and copper indium gallium (CIGS) solar cells based on silicon-based solar cells an attractive alternative because they require less equipment manufacturing and absorbed solar energy and resist good radiation characteristics.

However, manufacturing past, complex and expensive process hindered the thin film solar cells be used.

To make the battery in copper, indium, gallium and selenium ratio is correct, need to be very precise process. In the manufacture of thin film out, these proportions may change, affecting the ability to absorb energy. The method of magnetron sputtering enables the proportion of different materials, more reliable.

The manufacturing technology has been widely used in the film applied to glass, using the vacuum method and the magnetic field to ensure that the film material is applied evenly on the ground.

Professor Hill is currently carried out by application of thin film solar panel research and development, although only the laboratory scale, but the manufacturing technology has been widely used in practice is the maker of glass thin film solar cells used for be relatively easy and at low cost.

Battery makers, although the view was expressed that the car battery is not much profit, but long term, vehicle batteries become a huge market there are growth possibilities. This is because, if we can develop a low cost and excellent performance of the batteries, not only to hybrid and electric cars, and even living in between the two plug-in hybrids (using the home power charging, the battery runs out when the engine switch The hybrid drive), as well as hybrid fuel cell vehicle specifications, the amount of production will be boosted. Counter is to say, if the price and performance of lithium batteries is also as it is now, then the production of environmentally friendly cars can only be limited.

METI foresaw this, and was released in August last year, automotive batteries for future development goals. Target is divided into three stages. First of all, the first stage “to improve period” goal is by 2010 half the cost of lithium batteries (performance the same). Its implementation is the main industry, the establishment of the above-mentioned trends, such as automotive battery manufacturing companies all belong to this phase.

Stage 2 as an “advanced period”, will be in 2015 as the goal, so that the weight of the energy density of lithium batteries to 1.5 times the cost down to 1 / 7 (the cost of performance of 10 times). For example, plug-in hybrid electric vehicle mode, driving 150km, the need to be equipped 4kWh of rechargeable batteries, if you use the current lithium batteries, the battery is only necessary to ¥ 800,000. And if these goals are achieved, the battery would cost to 12 million yen, the weight of only the current 2 / 3.

Phase 3 is to extend beyond 2030, long-term goal is to make his request to 7 times the energy density, the cost to 1 / 40 (cost performance of 280 times). In order for electric vehicles and plug-in hybrids a large number of popular, need to develop the performance of the battery. Therefore, at this stage can be called a “reform period”, during this period the need for new principles of battery development, asked the University and research institutions to conduct long-term basic research.

The development objective is only produced in Japan by the province, “the basis for a new generation of cars - battery technology research Council” (Chair: Keio University, Professor, Graduate School Valley long) report “to a new generation of vehicle batteries’s recommendations” involved in the formal development plan has not yet implemented. While it is not know in what way the future to start R & D projects, but the second phase and third phase of objectives is still a huge leap worthy of attention. Prior to the second phase of industrial development issues, while the third phase of the “seven times the energy density of the development of new batteries” is entirely future results are not yet know how basic science questions. In this regard, at least cell research, experts believe that the target would disdain the development of purely “a layman’s absurd idea.”

But I made a leap Daoshi targets of the study would have a good impression. Now, to account for 20% of human energy consumption of vehicles to develop environmental protection measures is the world’s critical issues. In particular, the automotive industry will remain the pillars of economic development in Japan, saying that the challenges have to be this difficult issue. In my opinion, do not set such a high degree of difficulty, and does not deserve a state-led development program.

I worry about is that by the time the project is begun, subject to the views of industry representatives and experts strongly influenced by the target eventually be re-set to be achievable range. Admittedly, before the Japanese state-level development projects there is no such tendency. In my opinion, these use taxes for state-level development projects, the Government should look at the basis of society as a whole to develop clear goals, implementers should be afraid of failure, brave the challenges and development of new technologies. If you can not only improve the existing technology, but with a leap of new technologies to produce environmentally friendly cars dominating the world, it will be a very good thing.

Recall the number of the record industry’s most 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 department. 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 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 mobile phone industry and the notebook computer industry’s rapid development has 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 production date of December 2005 and November 2006 between the same origin as the Osaka battery.

Panasonic is expected to bear most of the costs to replace the battery is estimated to cost up to 170 million U.S. dollars. Affected by this news, yesterday in the Tokyo Stock Exchange, Matsushita shares fell nearly 5 percent, to close at ¥ 2015.
