2009年5月21日报道:可充电锂离子电池的首选电源存储技术是绝大多数便携设备,如手机,笔记本电脑和MP3播放器。
They have also made their way into electric cars , but even with recent developments making them more effective, storage capacity continues to remain a problem.
他们也取得了进入电动车 ,但即使与最近的事态发展使它们更有效的,存储容量仍然是一个问题。
Now researchers at the University of St Andrews, with associates at Strathclyde and Newcastle, have developed a new type of air-fueled battery that could provide up to 10 times the energy storage of existing designs, paving the way for a new generation of electric cars and portable devices.
现在,研究人员在圣安德鲁斯大学的,与同伙在斯特拉斯克莱德和纽卡斯尔,已经开发出一种新型的空气燃料电池,可提供高达10倍的能量储存的设计,从而为新一代电动汽车和便携式设备。提供电力。
Dubbed the STAIR (St Andrews Air), the new battery improves capacity by adding a carbon component.
被称为楼梯(圣安德鲁斯空军) ,新电池提高能力,增加了碳的组成部分。
Oxygen drawn in through a surface of the battery exposed to air reacts within the pores of the carbon to discharge the battery.
氧,(空气)通过电池表面的反应,暴露在空气中的毛孔内的碳,排放电池。
The discovery that the carbon component's interaction with air can be repeated, creating a cycle of charge and discharge, led to the development of the new battery
.这一发现,碳组成的互动与空气可以重复,建立一个循环充电和放电,导致了开发新的电池。
The technology should result in cheaper batteries since this process is free and the carbon component is less expensive than the lithium cobalt oxide used in lithium-ion batteries.
该技术应导致更便宜的电池,因为这个过程空气是免费的,而且碳“成本”是低于锂钴氧化物中使用的锂离子电池。
Also, by replacing one of the chemical components of rechargeable batteries, more energy can be created by the same-sized battery
.此外,更换一个化学成分的充电电池,更多的能量可以创造的同样大小的电池。
Reducing the size and weight of batteries, without compromising their charge capacity, should allow developers of electric cars to produce vehicles with greater range and provide longer life for portable devices.
减少尺寸和重量的电池,而不损害它们的充电容量,应允许开发的电动车生产的车辆提供更广泛和寿命更长的便携设备。
Initial results from the research project found a capacity-to-weight ratio of 1,000 milli-amp/hours per gram of carbon (mA/hours/g), while recent work achieved up to 4,000 mA/hours/g
.初步结果发现该研究项目的能力重量比1000 milli-amp/hours每克碳(毫安/小时/克) ,而最近的工作取得了高达四千毫安/小时/克。
Although the STAIR and lithium cobalt oxide technologies work very differently, the results equate to an eight-fold increase using the porous carbon electrode compared to the lithium cobalt oxide electrode found in standard cell phones.
虽然和锂钴氧化物技术工作非常不同,其结果等同于增长8倍使用多孔碳电极相比,锂钴氧化物电极在标准的手机。
The researchers believe the new design not only has the potential to improve the performance of portable electronic products, but also provide a major boost to renewable energy from sources, such as wind and solar by getting around the problem of intermittent supply when the weather changes or night falls.
研究人员认为,新的设计不仅有潜力,以改善性能的便携式电子产品,而且还大大推动可再生能源的来源,如风力和太阳能的遇到问题的间歇供应。当天气发生变化或夜幕降临时。
By discharging batteries to provide electricity and recharging them when the wind blows or sun shines, renewable energy becomes a much more viable option.
通过本电池提供电力和补给时风吹或阳光普照时,可再生能源“风电,光电,成为一个连续供电更可行的选择。受气候变化影响就少。
The researchers estimate that it will be at least five years before the STAIR cell is commercially available.
研究人员估计,这将是至少五年后可达商用水平。
