it’s used for: Cars Advantages: Could make a very light battery Obstacles: Finding electrolytes that don’t react with other components is a challenge; batteries have very short life span and may need extra safety engineering Source: Argonne National Lab Looking beyond 2017, scientists envision a new generation of batteries made of low-cost, or even no-cost, cheap jordans free shipping , materials. The lithium-air battery, still in early development, cheap jordan shoes , uses oxygen sucked in from the atmosphere to drive the chemical reaction that produces electricity. In the process, cheap real jordans , oxygen combines with lithium ions to form a solid compound (lithium peroxide). During charging, cheap jordans , solid oxygen reverts back to its gaseous form. “Lithium-air potentially offers the highest energy density possible,” says MIT materials engineer Ju Li. “You basically react lithium metal with oxygen in air, http://cheapjordansstock.com , and in principle you get as much useful energy as gasoline.” Lithium-air has problems, cheap Authentic jordans , though. The batteries are hard to recharge, losing much of their power during the process. And the chemical reaction that powers the battery generates heat, cutting the battery’s energy-storage capacity and life span. Using electron microscopy to study the reaction products of a lithium-air prototype, cheap wholesale jordans , Li and his group came up with a possible solution: Keep oxygen in a solid form sealed within the battery to prevent the oxygen from forming a gas. By encasing oxygen and lithium in tiny glasslike particles, cheap jordans online , the scientists created http://users.atw.hu/do...amp;topic=4599&page=1 http://www.arcobonsai....opic.php?f=1&t=212020 http://users.atw.hu/ba...amp;topic=6760&page=1 |
