Motor vehicles equipped with the thermal engines that equip modern cars primarily use a lead-acid battery to start the engine. The battery must provide a current of several hundred Amps for starting. Such batteries require high energy capacities, and their construction uses large amounts of Pb, an extremely polluting material. Also, the use of classic batteries in the automotive industry, in addition to pollution, is not effective either in terms of cost/weight When braking, electric cars generate large currents whose energy cannot be fully accumulated in batteries manufactured on the basis of Pb due to the limiting electrochemical process through which the electric charge accumulates. The modern computers that equip new vehicles have powerful processors that can command and supervise many phenomena on the car. A first step in this direction was made by the introduction of the Start-Stop system, which stops the engine when the vehicle is not moving or goes into the braking stage. When the accelerator pedal is pressed, the engine must start forcefully and at a higher speed than when the engine is running at “idle”. In this case, the starter is operated with a voltage 50% higher than the nominal voltage of the accumulator battery and a current of hundreds of amperes. In this case, a special passive component is used, namely the supercapacitor. A second step in the direction of reducing pollution is the considerable reduction of the battery capacity of Pb batteries, so less polluting, but which can ensure good starting even after a long time. This can be done by connecting a supercapacitor in parallel with a low-capacity Pb-based battery and an electronic control and monitoring system.","PeriodicalId":300380,"journal":{"name":"2022 IEEE 28th International Symposium for Design and Technology in Electronic Packaging (SIITME)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129011972","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For this reason, a good part of the research focuses on the use of supercapacitors as devices for storing the electric charge and at the same time generating this charge to the system that needs a power supply. The capabilities of supercapacitors can significantly contribute to the proper functioning of the system where they are embedded and can also prolong its life given the fact that they have a very large number of charge-discharge cycles (> 100,000). Like any relatively new component, which is constantly being tested, it has also some disadvantages that the researchers in this area have tried to reduce. The materials used in the realization of supercapacitors represent the main source of influence on their operation. For example, the maximum working voltage (nominal voltage) is determined by the electrolytic decomposition voltage of the electrolyte solution. Talking about this, the paper's aim was to make and test new coin cells of supercapacitors in order to increase the maximum working voltage and capacitance per cell. We propose to use new materials that seem to bring benefits from this point of view to obtain supercapacitors that work at higher working voltages (over 3V). Thus, after testing and interpreting the obtained data, we can conclude whether the materials have been chosen according, in combination between electrode material and electrolyte solution proved to be suitable in finding a solution to this disadvantage of supercapacitors.","PeriodicalId":300380,"journal":{"name":"2022 IEEE 28th International Symposium for Design and Technology in Electronic Packaging (SIITME)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123400913","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Dopants are essential for the actuating mechanism, considering a oxidation or a reduction process with exchange of anions / cations with the electrolyte. These processes are controlled by different parameters, like the relative diameter of the ions, the used electrolyte and the relative interaction forces solvent-ion, solvent-polymer, polymer-ions and polymer-polymer. For the two classes of dopants, the energy conversion efficiency was calculated based on the data obtained by simulation methods, using the microactuator structure reproduction, with help of the HFSS program (by Ansys). The efficiency can vary between about 20…40%, in function of molar ratios (0.1…0.4) and anions / cations ion radii. These parameters can be optimized analyzing a polyvalent evolution of the efficiency, in function of pairs of correlated parameters, which characterize the structure. Discussion is open in order to choose the practical meaning of the optimizing process, for recommending the optimal conductive polymer composition, used for actuation.","PeriodicalId":300380,"journal":{"name":"2022 IEEE 28th International Symposium for Design and Technology in Electronic Packaging (SIITME)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125032518","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
