The ultimate goal of a new generation of car batteries rather high
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.
