Waste lithium batteries become beauty of energy focus event

On February 18, is national battery day in the United States, many americans will replace the old batteries in the home in this day and sent to the recycling center. Unofficial and to celebrate this festival, the U. S. department of energy (doe) has announced, officially launched the argonne national laboratory battery recycling research and development center construction, start the lithium ion battery recycling award program at the same time, to promote the recycling of lithium battery in key materials.

since the early 1990 s were available, the use of lithium ion battery is more and more widely. Today, laptop computers, mobile phones to electric vehicles, energy storage devices, lithium-ion battery almost everywhere. Followed, it is waste lithium ion battery has increased at an alarming rate. Research has predicted that by 2030, the global scrap of lithium ion battery will reach 11 million tons. Now, the United States, the recovery rate of waste lithium ion battery is less than 5%. If this problem cannot be solved effectively, both to public health, or to the natural ecological environment, will cause bad movie

the U. S. department of energy (doe) argonne national laboratory set up battery recycling research and development center, to develop cost-effective advantage of recycling process, in as much as possible from the old in the lithium ion battery recycling lithium, cobalt, and other valuable materials. And start the lithium ion battery recycling award aims to encourage American companies waste lithium ion battery of the collection, storage, transportation and eventually recycling looking for innovative solutions. The doe will provide a total of $5. 5 million for the award of the bounty.

the department hopes that through the research and development center and recycling award two events, and promote the development of new technology, finally to achieve from the waste battery recycling 90% target of key material, in order to reduce the United States in the batteries, lithium, cobalt, the dependence on foreign material.

southern power grid research institute chairman RaoHong argues that to solve the dc voltage instability of feed-in bring more risk and ac/dc parallel running system Angle instability problem, southern power grid over the years by using asynchronous partition, such as flexible HVDC technology route, provides the reference for the similar international power grid development.
