Macrobian life (the right choice of Long-life) batteries, although be in low-down discharge condition, its importance is far pass pair of basic electricity - and - time (the analysis of Current-and-time) batteries capacity. The situation that rises to the interest that macrobian embedded applying takes the boundless engineering issue that come as long-range data record or ammeter: We how drive or charge for these equipment? These leave working facility in harsh environment normally, in power supply of a small cell and seldom below the condition that is paid close attention to, want the job 10, 20 older even. Work a few years to asking to be able to last only, the equipment with shorter lifecycle, the fundamental analysis that decision-making analysis uses electricity from bad news begins its batteries, like batteries all sorts of occupying sky comparing, and battalion carry mode and batteries capacity (the comparison of MA/hour) , can get comparativing so complex, miscellaneous application and operation are periodic, but it is too difficult that this is not met, at least can at worst set an upper limit. However, need to run 10 years when equipment or longer when, the basic electron of load current is analysed and the capacity of electric power is a minor influencing factor only, such as is corroded from discharge, chemical metamorphism and crust will become main problem. Read when me publish in spaceflight and national defence technology (Aerospace&Of Defense Technology) " design and the battery that make a few years (Designing And Fabricating A Multiple-Decade Battery) " when the article, cause why I will be very good to battery life strange reason. The article introduces the pyroelectricity generator that is based on radioactivity disintegration in detail (Thermoelectric Generator, TEG) , in theoretic can move 150 years, this framework uses process of a when never had looked before me two measure, produce light for disintegration; It is to use a solar battery to produce electric power next. The author alludes such means efficiency in the article inferior, did not list in article regrettablly number of exact changeover efficiency, but I suspect is to be in be less than the limits of 5% inside. This sees those who be like simple symbolic backside to indicate is electrochemistry, even the complex world of radioactivity action. The means that pyroelectricity generator charges through radioactivity disintegration is used successfully already 10 old, especially the spacecraft with sun the smallest radiate. These pyroelectricity generator are to use to be based on only course to change the heat energy that handles radioactivity disintegration, is not dichotomy (the photon of Two-step Process) , with Sebeck join is nodded (the electric power that Seebeck-junction) thermocouple produces from attenuation quantity of heat. Such means provides electric power for the Voyager 1 name that published 1977 and 2 machine, these two spacecraft still travel in aerospace at present and convey continuously data answers the earth, although they already crossed the ambiguous border of solar system,enter another deep space (Exospace) . (Make up by: The spacecraft provenance that article author mentions is by Stephen J. The Voyager that Pyne place writes: One book of Seeking Newer Worlds In The Third Great Age Of Discovery ~) has a few to use thermocouple to catch more than heat to work to also undertaking from engine, but how should these research turn into actual (cost, reliability, dimension and efficiency) still still not be clear about at present. Of course! Theoretic the time that you can need to use according to place, through use more magnetism core data, make a battery that is a foundation with disintegration, but the problem is, equipment how long needs to rest, and before electronic aggravation or fall to pieces, how will be the electron run continuously in using a program, this has nothing to do with the itself of radioactivity disintegration mechanism. But if batteries nots agree with,add up to the 100 demand that come for years, today will not somebody surrounds to criticize these works in instantly. I also am read other two articles about long endurance batteries, among them the batteries with right choice of batteries of a high-tech (Choosing The Right Batteries For High-Tech Batteries) , it is to come from brief of technology of total office of American country aviation and aerospace (with a view to of NASA Tech Briefs) the attribute of all sorts of chemical material, especially the mutation with a lot of interesting lithium familial battery, this article uses is for a word: Very complex. Need a few years 10 when you, be in even very cell is used below low-down electric current or loop of low rate pulse, meeting need analyses a lot of elements, discharge oneself for example and temperature rating, in addition, MA-Hr capacity also becomes one of parameter of numerous consideration. Although the author of afore-mentioned articles is one's previous experience from a famous battery manufacturer (Tadiran) , and probably the viewpoint has some of deviation, I aux would rather comply with the research record that already drove the certain public figure that issues a product in this domain truly, and the production with delicate product and manufacturing problem, is expert of a learning not just. (Make up by: Of meaning colloquialism of the author say even if... he is not quite trustful the argument of the expert of be an armchair strategist... ) supplier of pool of same home appliance also has a small " it is your wireless sensor power supply 40 years (Power Your Wireless Sensors For 40 Years) " article, this essay and in front mentioned article has partial one on top of another, also added a few new information nevertheless. Can you involve the option that decides long endurance batteries? How do you evaluate the capacity of main electric power that in complex operation periodic batteries place needs? The exterior that how you decide to grow endurance batteries again and chemical material can be feasible? CNC Milling
