After arranging the Wei Wen whereabouts, Lu Zhou turned around to return to the office, continued to prepare his ppt. 安排了魏文的去向之后,陆舟转身回到了办公室,继续准备他的ppt。 These days, his work will basically launch regarding „the theoretical model of galvanochemistry interface structure. 这段时间,他的工作基本上会围绕着“电化学界面结构的理论模型”进行展开。 Like this passed for a week, when Lu Zhou completed his ppt finally, suddenly receives the call that Yang Xu made. 就这样过去了一个星期,就在陆舟终于完成了他的ppt的时候,忽然接到了杨旭打来的电话。 The telephone just a connection, receiver that then broadcast the exciting sound. 电话刚一接通,听筒那头便传来了兴奋的声音。 We succeeded! We succeeded!” “我们成功了!我们成功了!” Heard that exciting tone, Lu Zhou gawked slightly, immediately asks: Lithium sulfur battery?” 听到那兴奋的语气,陆舟微微愣了下,紧接着立刻问:“锂硫电池?” Grasps Yang Xu of telephone to make an effort to nod, said agitatedly: Un! Your mentality is right, we use the glucose to be the precursors, chooses the polyaniline? The copolymer of ppy to make Kong Ji, successfully synthesized reached as high as 3022 m 2 / g compared with the surface area, simultaneously the diameter was only the 69 nm hollow carbon nanosphere.” 握着电话的杨旭使劲点头,语气激动道:“嗯!你的思路是对的,我们用葡萄糖为前驱体,选择聚苯胺?聚吡咯的共聚物为造孔剂,成功合成了比表面积高达3022m2/g,同时直径仅为69nm的空心碳纳米球。” Drinks water, agitated Yang Xurun the throat, continued to say impatiently. 喝了口水,语气激动的杨旭润了润嗓子,迫不及待地继续说道。 Then, we through the chemical deposition law, conducted the mix this type of hollow carbon ball and sulfur simple substance material, and assembles to the battery mold, conducted the battery performance test, the final result is quite gratifying.” “然后,我们通过化学沉积法,将这种空心碳球与硫单质材料进行了混合,并且组装到电池模具中,进行了电池组性能测试,最后的结果相当喜人。” Many things I did not say in telephone, the related experimental data I have sent to your mailbox, you look at quickly!” “多的东西我就不在电话里说了,相关的实验数据我已经发到了你的邮箱,你赶快看一下吧!” Good, my goes.” “好的,我这就去。” Sees Yang Xu expression to be excited, Lu Zhou also came the interest, then switched off the video call conveniently, mailbox that immediately registers. 见杨旭的表情如此兴奋,陆舟也是来了兴趣,便随手关掉了视频通话,立刻登录的邮箱。 Without arriving for five minutes, he then receives the mail that Yang Xu sent. 没到五分钟,他便收到了杨旭寄来的邮件。 After the attachment in mail downloads, Lu Zhou with the specialized microreader opens sketchily to reorganize the pdf form the experimental data, then from first part of starts, carefully read one after another. 将邮件中的附件下载下来之后,陆舟用专业的阅读器打开了粗略整理成pdf格式的实验数据,然后从第一部分开始,一行一行地仔细阅读了起来。 In this experimental data, not only there is a battery capability test data, but also is supplementing with the picture that the SEM films, as well as according to fluctuating curves of various data plans. 在这份实验数据中,不但有电池性能测试数据,还附带着用扫描电镜拍摄到的图片,以及根据各项数据绘制的变化曲线。 Just like Yang Xu said that the performance that this new-typed material shows is quite outstanding, no wonder his sound so excited. 正如杨旭所说的,这种新型材料展现出来的性能相当优秀,也难怪他的声音会如此的兴奋。 Compares in the primitive hollow carbon nanosphere and activated carbon nanosphere of caustic potash activation preparation, the composite material of this type of new hollow carbon ball and sulfur in the sulfur content with for 70% conditions, displayed more superior cyclic performance. 相较于原始的空心碳纳米球和经氢氧化钾活化制备的活性碳纳米球,这种新型空心碳球与硫的复合材料在硫含量同为70%的条件下,表现出了更加优越的循环性能。 Macroscopically is so, the change of microscopic level also quite interesting. 宏观上是如此,微观层面的变化也相当的有意思。 Sulfion of inserting in hollow carbon ball can leave from the surface pore of hollow carbon ball normally, and ordered with moving has the electrochemical reaction to the lithium ion of positive electrode, production crevice of between li2s2 and li2s in the carbon balls and carbon balls were quiet, avoided the aperture jamming influence galvanochemistry cycle efficiency. 嵌入在空心碳球中的硫离子能从空心碳球的表面孔隙中正常脱出,并且有序的与移动到正极的锂离子发生电化学反应,生成的li2s2和li2s在碳球与碳球之间的空隙沉寂,避免了孔径堵塞影响电化学循环效率。 On the other hand, because the charged sulfion with moving contacts to the lithium ion of positive electrode limitedly, avoided the long chain compounds lisn ( n > 2 ) formation in the enormous degree. 另一方面,因为带电的硫离子与移动到正极的锂离子有限接触,在极大程度上避免了长链状化合物lisn(n>2)的形成。 It is well known, is easy to dissolve in the long chain lisn member of organic solution then creates the prime culprit of shuttle effect, if can reduce the production of this product from the formation mechanism, was equivalent from the source prevented the outflow of anode material. 众所周知,易溶于有机溶液的长链lisn分子便是造成shuttle效应的元凶,如果能从生成机理上减少这种产物的生成,便相当于从源头上阻止了正极材料的流失。 Not only so, even produced lisn ( n > 2 ) chemical compound in the reacting system limitedly, because the surface adsorption of this type of hollow carbon ball, this type of polysulfide still by massive detentions in the skeleton of anode material, rather than across material surface diffusion to electrolyte. 不只是如此,即使在反应体系中有限的生成了lisn(n>2)化合物,由于这种空心碳球的表面吸附作用,这种多硫化合物也会被大量的滞留在正极材料的骨架中,而不是穿过材料表面扩散到电解液中。 Had these two insurances, the influence of shuttle effect is dropped lowly. 有了这两层保险,穿梭效应的影响已被下降到了最低。 Crossed part that records about the physical and chemical property analysis, Lu Zhou looked directly to the part of battery test. 翻过了记载着关于理化性质分析的这一部分,陆舟直接看向了电池组测试的部分。 According to Jinling calculates many groups of battery testing that the material research institute makes, when the sulphur content is 73%, reaches the peak value to the polysulfide to the inhibiting ability that the electrolyte spreads. After 500 circulations, Coulombic Efficiency still placed the quite high level. 根据金陵计算材料研究所做的多组电池组实验测试,当含硫量为73%的时候,对多硫化合物向电解液扩散的抑制能力达到峰值。在500次循环之后,库伦效率依然维持在相当高的水平。 When the sulphur content is 75%, synthesizes Coulombic Efficiency and quality energy density and volume energy density wait a series of factors, the comprehensive feature of battery reaches the best level. 而当含硫量为75%的时候,综合库伦效率、质量能量密度、体积能量密度等等一系列因素,电池的综合性能达到最佳水平。 About this new hollow carbon ball material, Yang Xu according to the nomenclature that Lu Zhou previously formulated, names as the hcs-2 material it. 关于这种新型空心碳球材料,杨旭按照陆舟先前制定的命名原则,将其命名为hcs-2材料。 Compares the industrial application value relatively limited hcs-1 material, this new material has the possibility of industrial production without doubt! 相比起工业应用价值相对有限的hcs-1材料,这种新材料无疑更具备工业生产的可能! Simply perfect.” “简直完美。” Placed on the test report in hand the table, Lu Zhou sighed with emotion one in the heart, then takes out cell phone from the pocket, calls Starry Sky Technology general manager Mr. White Sheridan, making him start to conduct the application of international monopoly immediately. 将手中的实验报告放在了桌上,陆舟在心中感慨了一句,然后从兜里取出手机,给星空科技的总经理怀特・谢里丹先生打了个电话过去,让他立刻开始着手进行国际专利的申请。 Considering this material in the widespread prospect of industrial application domain, Starry Sky Technology will act according to this research results, and other series of aspects registers the patent regarding the chemical compound, production, use, with sulfur simple substance the mix allocated proportion of hcs-2 material respectively, establishes one set of complete patent barrier. 考虑到这种材料在工业应用领域的广泛前景,星空科技将根据这项研究成果,围绕hcs-2材料的化合物、生产、用途、与硫单质的混合配比等一系列方面分别单独注册专利,建立一整套完整的专利壁垒。 The situation optimistic words, before the end of the month, he can attain the patent number, then can start writing of paper. 情况乐观的话,在月底之前,他就可以拿到专利号,然后便可以开始论文的撰写。 As using the model of computation material method solution practical problem, the success of hcs-2 material, for his galvanochemistry interface structure theoretical model, will provide an important fact argument without doubt. 作为运用计算材料方法解决现实问题的典范,hcs-2材料的成功,无疑将为他的电化学界面结构理论模型,提供一个重要的事实论据。 Compares this carbon sulfur composite material, regarding this point, Lu Zhou especially anticipated...... 相比起这个碳硫复合材料本身,对于这一点,陆舟尤为期待…… ...... …… That side White is highly efficient, Lu Zhou told that is very long, all documents that submit the patented claim, success adopted the application. 怀特那边的工作效率很高,陆舟吩咐下去没过很久,所有提交专利申请的文件,都成功的通过了申请。 After attaining the patent number, he starts writing of paper immediately. 拿到了专利号之后,他立刻开始论文的撰写。 Previous time the paper about hcs-1 is also he writes, has the ready-made template to apply mechanically, the writing of this paper has not spent the Lu Zhou too much time actually, less than three days then handled the entire chapter paper. 上次关于hcs-1的论文也是他写的,有现成的模板可以套用,这次论文的写作倒是没有花费陆舟太多的时间,不到三天便搞定了整篇论文。 Considering that adds up to a series with hcs-1, this one time, he still chose " Science " as the contribution object, transmitted the mailbox of " Science " editorial department the manuscript. 考虑到和hcs-1凑成一个系列,这次一次,他依然是选择了《科学》作为投稿对象,将稿件发送到了《科学》编辑部的邮箱。 After throwing completes draft, Lu Zhou again has not then gone to manage it, will start to soon the public lecture that will hold in German MPI Society to prepare. 投完稿之后,陆舟便没有再去管它,开始为即将在德国马普学会举行的报告会做准备。 However compares optional attitude of Lu Zhou when the contribution, this mail is lets " Science " editorial department worries. 然而相比起陆舟在投稿时随意的态度,这封邮件却是让《科学》的编辑部犯了难。 On irrigates in " Science " is greatly ox Men the pleasure, for example and Lu Zhou has David Xiao of cooperation in the theoretical model of galvanochemistry interface structure is one of them. 在《科学》上灌水是很多大牛们的乐趣,比如和陆舟在电化学界面结构的理论模型上有过合作的大卫・肖就是其中之一。 But " Science " also welcome these ox Men to irrigate on oneself greatly, after all these ox Men equipment often enough makes the peer be jealous greatly, the paper quality has the academic reputation to guarantee, but also bringing current capacity effect. 而《科学》也非常欢迎这些大牛们在自己身上灌水,毕竟这些大牛们的设备往往足够让同行眼红,论文质量有学术声誉保证,还自带“流量效应”。 However Professor land in the half year three contributions irrigation speed , was too rather astonishing the point...... 然而陆教授这半年三次投稿的“灌水”速度,未免也太惊人了点…… The issue is not lies in the hcs-2 material, but is mathematicasis edition in mostly the editorial department does not believe, Lu Zhou can in such a short time, make the so major change based on hcs-1 material. 问题不是在于hcs-2材料本身,而是编辑部里的大多数学术编辑都不相信,陆舟能在如此短的时间里,在hcs-1材料的基础上做出如此重大的改变。 Considering the paper of that carbon sulfur composite material recently «jacs» on published, as well as in the sensational effects that the energy industry sparked. 考虑到最近《jacs》上刊登的那个碳硫复合材料的论文,以及在能源行业引发的轰动效应。 Some anybody reasons suspected, Professor land possibly for competes in the lithium sulfur battery project with Professor Stanley, in revising the situations of some experimental data, published not yet the perfect experiment achievement. 任何人都有理由怀疑,陆教授可能是为了与斯坦利教授在锂硫电池项目上竞争,在修改了部分实验数据的情况下,发表了尚未完善的实验成果。 This sounds like somewhat risky, but in the academic circle, such matter may have the precedent. 这听起来似乎有些冒险,但在学术界,这样的事情可不是没有先例的。 The " Science " editorial department cannot make up mind, finally played this rubber ball to the reviewer. 《科学》的编辑部拿不定主意,最终还是将这个皮球踢给了审稿人。 This time is responsible for reviewing a draft for Professor land, as before is Professor Bawendi of Massachusetts Institute of Technology. 这次负责替陆教授审稿的,依旧是麻省理工大学的巴旺迪教授。 As before, this does not believe in evil doctrines professor after receiving edit invitation, still shells out naturally, according to that test report that Lu Zhou provides, repeated the experiment like an honest and good-natured person. 和以前一样,这位“不信邪”的教授在接下了审稿邀请之后,依然是大方地自掏腰包,按照陆舟提供的那份实验报告,像一个老实人一样重复了实验。 No matter he does believe in evil doctrines, finally is placed in his front. 然而不管他信不信邪,结果都摆在他的面前。 This time, he double ruo zhuo did not succeed carefully...... 这一次,他又双叒叕不小心成功了……
