    锂硫电池的硫正极因具有高达1675mAhg-1的理论比容量,以及硫资源的丰富,无毒,且廉价等诸多优点,近年来受到了广泛的关注,成为当前的研究热点。然而锂硫电池的实用化还面临着三大挑战:1、活性物质S既是电子绝缘体,又是离子的不良导体,会降低活性物质利用率和不利于高倍率的实现;2、活性物质S到终产物Li2S和Li2S2较大的体积膨胀,会造成正极结构的破坏,影响电池的循环性能;3、锂硫电池中最严重影响其实用化进程的因素是放电中间产物多硫化锂能够溶于电解液,并能穿过隔膜到达负极与锂反应,产生过充现象,造成容量的不可逆衰减,即锂硫电池的穿梭效应。本论文基于对隔膜进行改性,来抑制穿梭效应,从而提高锂硫电...Sulfur cathode in lithium-sulfur battery has been widespread concern and become a hot research in recent years, because of its high specific capacity of up to mAh g-1, and sulfur resources’ abundance, non-toxic, and cheapness and many other advantages in the Earth.

    自2006年,随着中国证券市场股权分置改革取得阶段性成果,市场融资功能得以恢复,同年5月9日,证监会颁布《上市公司证券发行管理办法》引入定向增发,对于拓宽上市公司的再融资渠道、收购资产、吸收合并、引入战略投资者及资产重组具有重要的战略意义和作用。 目前,我国相关的法律法规、证监会的规定中没有对定向增发的含义有明确的界定,简单来说就是上市公司对特定对象非公开发行股票,募集资金的行为。对定向增发的操作比照的是非公开发行的规定,但是从实践操作来说,两者还是有一定的区别,非公开发行是向10家以下的对象发行,一般为机构投资者,融资的目的比较强,而定向增发是向特定的机构,一般为战略投资者,大多与重组有关...Since 2006, with the China equity securities market reform achievements, to market financing function, the same year in May 9th, the Commission issued "the issuance of securities of listed companies management approach" the introduction of private placement of listed companies to broaden the financing channels, to purchase assets, has strategic significance and function of merger, the introduction...学位:工商管理硕士院系专业:管理学院_工商管理硕士(高级管理人员工商管理硕士)学号:X201315609
