Lu Zhou replied: „I come.” 陆舟回答道:“我来吧。” The system had not stipulated that does the experiment to by whom operate, so long as will test to do, then collected the data that needs to collect on the line. The goal of however not being the study, Lu Zhou wants to begin to operate one personally. 系统并没有规定做实验必须由谁操作,只要将实验做一遍,然后收集需要收集的数据就行了。不过不出于学习的目的,陆舟还是想亲自动手操作一遍的。 After all, the paper can come up to think finally shallowly, in the books gives him is the theories, only then carries out, can turn into the real fellow the black science and technology in that legend. 毕竟,纸上得来终觉浅,书本上交给他都是理论,只有落实到手上,才能将那传说中的黑科技变成真家伙。 Had the ceremony feeling to change the white coat very much, Lu Zhou put out the imposing manner of scientist slightly, extended the deep breath the one breath, put out a hand to take that to think to experiment the material the sample box. 很有仪式感地换上了白大褂,陆舟稍微拿出了点科学家的气势,伸深呼吸了一口气,伸手去拿那个装着实验材料的样品盒。 However, his hand has not traced, was seized by quick of eye and hand Senior Brother Qian. 然而,他的手还没摸到,就被眼疾手快的钱师兄一把夺过去了。 „I come, at the same time looks.” “还是我来吧,一边看着。” Without demur, Senior Brother Qian then took over control of the initiative of experiment, dries in the sun Lu Zhou that a face compels ignorant in side. 二话不说,钱师兄便接管了实验的主动权,把一脸懵逼的陆舟晾在了旁边。 Looks to Big Brother Liu, is holding Big Brother Liu of both arms, helpless shrugs. 看向刘师兄,抱着双臂的刘师兄无奈耸了耸肩。 „Do not mind, the old money is this, here instrument like his wife, assigns/life importantly...... you to visit him to make one compared with him for the first time.” “别介意,老钱就是这样,这里的仪器就像他老婆,比他命都重要……第一次你还是看着他做一遍吧。” Senior Brother Qian does not return, later said: „Does the experiment not to do the math, miscalculated a decimal point to change can also then calculate, the experiment made a mistake a small detail, possibly caused the entire experiment to discard. Naturally, what I fear is you discarding...... shows your experiment flow of design me the experimental device.” 钱师兄头也不回,随后说道:“做实验不是搞数学,算错了一个小数点改一改还能接着算,实验错了一个小细节,可能导致整个实验废掉。当然,我更怕的是你把实验器材给废掉……把你的设计的实验流程那给我看看。” „Here.” Lu Zhou took that a4 paper rapidly. “在这里。”陆舟迅速拿出了那张a4纸。 The experimental data that the system requirement laboratory procedure and needs to collect, he wrote above. 系统要求进行的实验步骤和需要收集的实验数据,他都写在上面了。 Senior Brother Qian received the a4 paper to sweep one, nods: „Design is very specialized.” 钱师兄接过a4纸扫了一眼,点了点头:“设计的还挺专业的。” emmm...... emmm…… After all is the system design. 毕竟是系统设计的。 The Lu Zhou expression is subtle, without speech. 陆舟表情微妙,没有说话。 ...... …… The flow of experiment is very simple, from manufacturing the battery starts, to observation phenomenon. 实验的流程很简单,从制作电池开始,到观察现象。 Uses 95.7% graphites to take the negative electrode material, the bond for cellulose glycolate sodium ( cmc ) and butadiene styrene rubber ( sbr ), the collection fluid is the copper foil. The graphite level thickness is 90 m, the positive electrode active material uses lifepo4, the collection fluid is the aluminum foil. 使用95.7%的石墨作为负极材料,粘合剂为羧甲基纤维素钠(cmc)和丁苯橡胶(sbr),集流体为铜箔。石墨层厚度为90m,正极活性材料使用lifepo4,集流体为铝箔。 As for mutual lack of understanding, what used is the celgard2325 three mutual lack of understanding, the thickness makes 25 m. 至于隔膜,用的是celgard2325的三层隔膜,厚度约25m。 In order to prevent the material oxidizes, all operations in filling the glove box of argon are conducted. 为了防止材料氧化,一切操作都是在充满氩气的手套箱中进行的。 Naturally, not only to prevent the material oxidizes, colleague also to prevent the lipf6 ingredient in electrolyte, in water response production hydrofluoric acid with air. 当然,不只是为了防止材料氧化,同事也是为了防止电解液中的lipf6成分,与空气中的水反应生成氢氟酸。 Hydrofluoric acid thing, studies the people of high school chemistry to know. 氢氟酸这东西,学过高中化学的人都知道。 But this gadget dangerous, in the silicon-based micro electron laboratory has treated person, should very be also clear. In which hand wipes, this hand basically had no way to see the person. 而这玩意儿有多危险,在硅基微电子实验室待过的人,应该也都很清楚。哪只手上抹一点,这只手基本上就没法见人了。 From the Senior Brother Qian operational procedure, obviously compared with Lu Zhou this theoretician specialized many. 从钱师兄的操作流程来看,显然比陆舟这个理论家专业的多。 Quick, the sample then manufactures to be completed. 很快,样品便制作完成。 In order to prevent the sample was destroyed, what use is side the assembly way of opposite side. Senior Brother Qian uses a mutual lack of understanding in the glove box the lifepo4 material complete gable, and kept the 2 mm spacing the positive and negative extremely free electricity cautiously. 为了防止样品被破坏,使用的是边对边的组装方式。钱师兄在手套箱中用一层隔膜将lifepo4材料完全包覆,并小心翼翼地将正负极自由端留出了2mm的间距。 These step is very essential, is concerning the security of experiment. 这一步很关键,关乎着实验的安全。 Took out the sample from the glove box, Senior Brother Qian closed various group of air valves, long exhales. 从手套箱中取出了样品,钱师兄关闭了各路气阀,长出了一口气。 „Handles.” “搞定。” Looks at the sample in Senior Brother Qian hand, Lu Zhou asked: „Is this battery?” 看着钱师兄手中的样品,陆舟问:“这是电池？” „Simple, and unsafe Lithium ion battery,” Senior Brother Qian briefly and to the point introduced. “一个简易且不安全的锂离子电池,”钱师兄言简意赅地介绍道。 Lu Zhou anxious: „Will explode?” 陆舟紧张了一下:“会爆炸吗？” Senior Brother Qian shakes the head: „Explodes to not, but operates improper, may cause to be on fire.” 钱师兄摇头:“爆炸到不会,但操作不当,可能会导致起火。” Moreover, is on fire on the digital microscope. 而且,是在数码显微镜上起火。 Burnt out actually the minor matter the sample, the lens of digital microscope roasting, that trouble was big. 把样品烧坏了倒是小事,把数码显微镜的镜头给烤了,那就麻烦大了。 Lu Zhou estimated, this is Senior Brother Qian is bumped one of the experiment reasons by oneself this novice. 陆舟估计,这也是钱师兄不让自己这个新手碰实验的原因之一。 Joined bk-6808 to be possible the sample the rechargeable battery reflectoscope reflector, then placed on the digital microscope, Senior Brother Qian was establishing several parameters to the computer, at the same time thought aloud resulted is repeating the step on paper low voice: „2 min collects image a time, the data data collection frequency is 1 hz, after the battery initial charge to 400 min, discharged to the black-out voltage...... ok.” 将样品接上了bk-6808可充电电池性测试仪,然后放在数码显微镜上,钱师兄对着电脑设置了几个参数,一边自言自语似得小声重复着纸上的步骤:“2min采集一次图像,数据数据收集频率为1hz,电池首次充电至400min后放电至截止电压……ok了。” Remaining, was the long waiting. 剩下的,就是漫长的等待了。 Looks at that unrelieved instrument, Lu Zhou cannot bear ask: „Do you perform the battery material experiment to wait is so long?” 看着那毫无变化的仪器,陆舟忍不住问道:“你们做电池材料试验都要等这么久吗？” 400 minutes, this nearly seven hours. 四百分钟,这都快七个小时了。 Senior Brother Qian pushed the eyeglasses saying: „Seven hours are the elementary operation eos, sometimes must wait for several days to see the result, in the ordinary circumstances will remain is on duty in the laboratory personally, basically is I and Liu Bo two does in turn.” 钱师兄推了推眼镜说道:“七个小时是基本操作,有时候还得等几天才能看到结果,一般情况下会留个人在实验室值班,基本上是我和刘波两个轮流做。” „Right,” Liu Bo said, „last year one year I brushed more than 40 plays, is in the laboratory is on duty brushes, wants me to give you to recommend the point?” “没错,”刘波笑着说,“去年一年我刷了四十多部剧,就是在实验室里值班的时候刷的,要我给你推荐点吗？” Lu Zhou: „This, does not use.” 陆舟:“这个,还是不用了吧。” Even recommended, he still has no time to look mostly. 就算推荐了,他多半也没什么时间去看。 After the operation that needs to make all completes, Senior Brother Qian taught Lu Zhou some simply, processes the sudden outbreak the method. 需要做的操作全都做完后,钱师兄简单地教了陆舟一些,处理突发状况的方法。 For example sees the sample to belch smoke, smells not the right smell, how should clean up the damage sample, how to protect the instrument, as well as most essential how to protect itself. 比如看到样品冒烟,闻到不对劲的气味,该如何清理损毁样品,如何保护仪器,以及最关键的如何保护自己。 Regardless of the instrument is expensive, cannot compare the person to be important. 无论仪器多么贵重,都比不上人重要。 Naturally, this experiment is not dangerous, in Senior Brother Qian felt relieved very much threw on the key Lu Zhou. 当然,这个实验并没有那么危险,所以在钱师兄很放心地将钥匙扔到了陆舟手上。 He and Big Brother Liu a little matter, are impossible to treat here, but Lu Zhou also embarrassed such troublesome families. After all does this experiment, has lost their a lot of time. 他和刘师兄还有点事,不可能一直待在这里,而陆舟也不好意思这么麻烦人家。毕竟做这个实验,就已经耽误他们不少时间了。 Takes the book of quantum color dynamics, Lu Zhou sits in side of digital microscope, crams ferociously the knowledge in theory Physics aspect, while glances situations on two digital microscope once for a while. 将量子色动力学的书拿出来,陆舟就坐在数码显微镜的旁边,一边恶补理论物理学方面的知识,一边时不时地瞟两眼数码显微镜上的情况。 Arrived afterward, him discovered that oneself definitely does not need cautiously, to stay under the microscope like this was so long, outside seems like a change not to have. 到后来,他发现自己完全没必要这么小心翼翼,这样品在显微镜下呆了这么久,外面看上去一点变化都没有。 Can look, Senior Brother Qian makes the craftsmanship of experiment, is quite credible. 看得出来,钱师兄做实验的手艺,还是相当靠谱的。 From morning 10 o'clock, has stayed quick evening's 6 o' clock in the laboratory, in this period Lu Zhou also called to go, had the lunch. 从上午十点多开始,在实验室一直待到了快晚上六点,期间陆舟还叫了个外卖,吃了中午饭。 Finally, the time of setting arrived, the charging and discharging finished, Lu Zhou according to Senior Brother Qian said that stayed the opening condition to wait for 10 minutes, then dump. 终于,设定的时间到了,充放电结束,陆舟按照钱师兄说的,保持开路状态等待了十分钟,然后切断电源。 Almost after he completed the work of these conclusions, outside the laboratory heard the sound of footsteps, had just eaten dinner Big Brother Liu in the cafeteria, almost stepped on to select the laboratory. 几乎就在他做完了这些收尾的工作之后,实验室外传来了脚步声,刚在食堂吃过晚饭的刘师兄,几乎是踩着点到了实验室。 „Handled?” Looked at the sample situation, Big Brother Liu proficiently operated the computer, the point was choosing the button of printing, „that collection data.” “搞定了？”看了眼样品的情况,刘师兄熟练地操作着电脑,点选了打印的按钮,“那就收集数据吧。” Resounding of printer wēng wēng. 打印机嗡嗡的响起。 Quick, Lu Zhou obtains the thing that he wanted. 很快,陆舟得到了他想要的东西。 One group records lithium dendrites in the picture that under microscopic grows, circulation voltage curve that and system requirement collects and so on graph wait. 一组记录着锂枝晶在微观下生长的图片,以及系统要求收集的循环电压曲线之类的图表等等。 Is collecting these data, Big Brother Liu while said with the chatting tone. 一边在收集这些数据,刘师兄一边用闲聊的口吻说道。 „...... The lithium is the most ideal negative electrode material, but is also most difficult to serve. In the charge, returning to the cathode the lithium ion never to meet such as you to hope, changes the smooth lithium conductive sea honestly, but to blossoming to be the same, forms a beautiful and fatal crotch.” “……锂是最理想的负极材料,但也是最难伺候的。在充电的时候,回到负极的锂离子永远不会如你所愿,老老实实变回平坦的锂金属层,而是会向开花一样,形成一个美丽而致命的树杈。” Waits for printer seal to end the graph, Lu Zhou speaks thoughtlessly to ask: „Fatal?” 等待着打印机印完图表,陆舟随口问道:“致命？” „Yes, the thing of this type of calling arborescent crystal, once forms, with will charge unceasingly, but unchecked continuation growth, but finally like a fork, will puncture the mutual lack of understanding, contacts the positive electrode.” “是的,这种叫枝晶的东西一旦形成,就会随着不断充电而不可遏制的继续生长,而最终就会像一把叉子一样,刺破隔膜,接触正极。” At this point, Big Brother Liu stopped, said with the tone of cracking a joke: „Imagines, what situation if with an electric wire together with the positive electrode and cathode of battery is? Right, short-circuits. But the organic electrolyte is the combustible, has heard moli Corporation?” 说到这里,刘师兄停顿了一下,用开玩笑的语气说的:“想象一下,如果用一根电线连同电池的正极和负极是什么情形？没错,就是短路。而有机的电解液都是易燃物,听说过moli公司吗？” „Without...... how?” “没有……怎么了？” Big Brother Liu shrugs, the a4 paper that will print handed over on Lu Zhou, „their products almost made the history, but is because used the lithium to make the cathode, finally had the fatal safety incident, finally caused ntt cell phone to be recalled, finally the company went bankrupt is purchased. In comparison Sony is very intelligent, makes the cathode with the graphite directly, promoted the Lithium ion battery quickly to capture the market share.” 刘师兄耸了耸肩,将打印出来的a4纸交到了陆舟手上,“他们的产品差一点创造了历史,但就是因为用了锂做负极,结果发生了重大的安全事故,结果导致ntt手机被召回,最后公司破产被收购。相比之下索尼就很聪明,直接用石墨做负极,推出锂离子电池迅速占领了市场。” Lu Zhou cannot bear ask: „Haven't they made the security testing?” 陆舟忍不住问:“他们难道没有做安全测试？” Big Brother Liu sighed: „Yes, is individual will ask, but the matter is possibly less simple. Perhaps did simply had not found the problem? Perhaps they think that oneself did find the perfect solution? Who knows? Sometimes, the reality is magic such.” 刘师兄叹了口气:“是啊,是个人都会这么问,但事情可能远远没这么简单。也许做了根本没发现问题？也许他们认为自己找到了完美的解决方案？谁知道呢？有时候,现实就是这么的魔幻。”
