  • 7. 1. TRIZ, concepts Hybridization as a TRIZ concept and the hybrid battery-supercapacitor “This system that we have gives you capacitor-like power with battery-like energy," said U Illinois Paul Braun, a professor of materials science and engineering. "Most capacitors store very little energy. They can release it very fast, but they cant hold much. Most batteries store a reasonably large amount of energy, but they cant provide or receive energy rapidly. This does both."

Solutions of different industries to the specific problem of oxygen diffusion in lithium 1.addition of metal oxide Moreover, addition of the metal oxide in the described manner apparently increases the macroporosity and total pore volume of the activated carbon. EP-2289609 A1Method for making activated carbon for odor control 2.special treatment Special treatments have been developed for increasing the pore volume and the specific surface area of activated carbons (T. Ottawa, R. Tanibata, M. Itoh, G Separation Purification 1993, 7, 241). O Gas S f ) US-20110005392 A1PROCESS FOR SEPARATION OF CO2 BY PRESSURE-MODULATED ADSORPTION ON A POROUS CARBON SOLID 3.application of acid treatment with aqueous solution of hydrofluoric acid It was confirmed that the pore volumes of the porous carbon materials according to the present invention ...the mercury invention... the penetration method were significantly increased by the application of an acid treatment with an aqueous solution of hydrofluoric acid (expressed as “hydrofluoric acid... US-20100069507 A1Porous Carbon Materials and Production Process Thereof, and Adsorbents, Masks, Adsorbing Sheets and Carriers 4.thermal activation process The thermal activation process greatly increases the pore volume and surface area of the carbon particles by elimination of volatile pyrolysis products and from carbonaceous burn-off. US-5769933Activated carbon foundry sand additives and method of casting metal for reduced VOC emissions EP-0813921 A1Foundry sand additive and method of casting metal 5.Mg deposition, decreasing specific surface area of parent carbon Mg deposition either increases or decreases the specific surface area, pore volume, and average micropore width of the parent carbon depending on the preoxidation temperatures.

  • 32. 4. CONCLUSIONS.The mining of thousands of documents and patents can bringsome more rigorous clues of what are the key trends. The mainresearch line around improving cathode performance with LiFePO4 material was p g pidentified. Among emergent technologies was feasible to identify Li-Ar as the most promising. Leap in articles and patents production indicators in last years may suggest that Li-Ar is coming from the design to the improvement phase. ©2011, triz XXI todos los derechos reservados <informa@triz.es>, www.triz.es
  • 33. 4. CONCLUSIONS.the TRIZ inventive principles and laws come in hand to understandmany of the current limitations and its possible outcome in nextresearch results. The usage of Tech Mining d T h Mi i and syntactic-semantic t l better if t ti ti tools, complemented with a knowledge of TRIZ, can short cut the time needed to analyze what is progressing as well as to ascertain in a more objective and accurate way the trends identified, based on a vast array of research, patented inventions and innovation, directions. ©2011, triz XXI todos los derechos reservados <informa@triz.es>, www.triz.es
