energy-storage technology that could boost the range of electric cars.\u00a0 <!--more-->Ultracapacitors have the advantage of delivering fast bursts of power and can be recharged hundreds of thousands of times without losing much capacity, but conventional ones are expensive and store too little energy to replace the traditional batteries.\u00a0 A startup called Nanotune, based in the United States, has now developed a way to make electrodes that result in ultracapacitors with five to seven times as much storage capacity as conventional ones.\u00a0 Nanotune says its ultracapacitors could soon surpass batteries in terms of energy storage.\u00a0 All of the start-ups are hoping to solve the biggest problem with electric cars today \u2013 the high cost of the batteries and the limited storage capacity.\u00a0 Today\u2019s battery systems are expensive and bulky because the batteries degrade as they are used, and when exposed to extreme temperatures.\u00a0 Automakers often pair batteries with cooling and heating systems, and extra battery cells, to offset losses in performance over time.\u00a0 Ultracapacitors can be recharged without degrading and work well in a wide range of temperatures.\u00a0 Nanotune\u2019s technology is currently very expensive, but the company says the costs could come down if the prices of some key materials continue to fall, and as manufacturing is scaled up.\u00a0 Nanotune CEO\u00a0 Kuan-Tsae Huang says the company hopes to double the current storage capacity of its ultracapacitors by the end of the year, which would result in an improvement over the batteries used in some hybrid vehicles.<\/p>\n<p>http:\/\/www.technologyreview.com\/energy\/37519\/<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Several start-ups have recently
