"Strictly speaking, there is no real gel battery in our country."

"That's not right, is it?" Hearing the boatman's words, Lin Zheng frowned, since he is engaged in this industry, he naturally has to maintain a certain attention to the battery technology exhibition, although he has not deliberately paid attention to the lead-acid battery, the battery on his car is also old-fashioned, need to add electrolyte maintenance battery, but the information in the introduction of the battery-related information always have some comparative information, see more and know more, "I remember that in our country, the colloidal battery is very hot." ”

The boatman is not annoyed, Lin Zheng is not a person in the battery industry, he has heard of some colloidal batteries, but he doesn't know the details, this is too normal, if Lin Zheng knows a lot about batteries, is it necessary for him to call himself? I can't explain to Lin Zheng: "It's one thing to be hot, in fact, the commercial value of gel batteries was taken care of as early as the mid-to-late eighties, and the research on gel batteries began. ”

"However, because the technical blockade of foreign countries on us at that time was not opened, there was little understanding of gel batteries in China...... At that time, our research institute only knew that the colloidal electrolyte was composed of colloidal sol silica...... There are capable people who can use the starter battery to charge without changing any structure of the battery, add the treated sodium silicate to the battery, and then add sulfuric acid electrolyte to produce the so-called 'gel battery', and it is also claimed that the battery capacity of this gel battery has increased by more than 1o%, ~2 times. ”

"It's impossible!" Lin Zheng said that although he is not engaged in batteries, the operation of mobile devices does not depend on batteries? I don't know that the battery industry is no problem, but some understanding of the characteristics of the battery is a must in the industry, this so-called "gel battery" still dares to claim that the battery capacity has increased by more than 1o%. "Isn't that typical nonsense? The actual capacity can only reach 8o%~85% of the same capacity starter battery, which is very good. ”

"It's not just 8o% to 85% of the starter battery?" The boatman laughed vigorously, "And the capacity of the battery drops sharply after dozens of cycles." ”

"Well, why is that?" Boss Lin listened with some curiosity.

"It's very simple, the silica sol seals the micropores of the PVC separator. The resistance of the separator increases. Some partitions don't even conduct electricity at all, they don't conduct electricity anymore. Will this battery still work? The boatman brother smiled more and more happily, "I don't know if you have any impression of the lawsuit between the 'Neptune' gel battery and the Shen & Yang Battery Research Institute?" At that time, this lawsuit shocked the relevant leaders of Liaoning Province and the First Ministry of Machinery Industry. ”

"It's so big?" Lin Zheng was taken aback when he heard it, the lawsuit between Neptune Colloidal Battery and Shen Chu was a shocking power at the beginning, how could he not know? At that time, I was still in school and my classmates "pointed out the country".

"What's big? It's nothing more than thunder and rain. The boatman said disdainfully, "Do you know how it ended up?" In the end, the Ming people disappeared, and the matter was over. ”

"This is really ......" Lin Zheng only smiled bitterly, it is said that he has alarmed the leaders of the province and the leaders of the ministry, this is a big deal, right? In the understanding of ordinary people, it's normal to get a few people out, right? It's not impossible for someone to lose their head, it was the end of the 8o. But who would have thought that it would be so thunderous and rainy?

"What's that?" The boatman snorted, "If you know that there were then manufacturers and research institutes that sold colloidal electrolytes and produced colloidal batteries in at least 5 provinces and municipalities directly under the central government, and the colloidal electrolytes sold were similar to the former, all of which were made of 1og separators or glass wool separators and then added to the silica sol to become colloidal batteries, and even after charging with poor liquid sealed batteries (AGM). Adding a layer of silica sol on top of the polar group also becomes a gel battery...... You say, how fucked up is this? ”

Some of the boatmen haven't said anything yet, the colloidal electrolyte of these manufacturers is not only similar to the colloidal electrolyte in the previous lawsuit, but also one by one they claim to be "domestic leading technology, the quality is comparable to the German 'sunshine battery', and even some indicators are better than the sunshine battery", which is simply not an ordinary disgusting person.

"Indeed...... Enough to fuck up. Lin Zheng also nodded speechlessly, although the boatman didn't say it, but Lin Zheng could also think that since then, this so-called "gel battery" has not sprung up like mushrooms after a rain? But here's the problem, the performance of these batteries is simply impossible to meet the promised indicators, and then it is understandable that users are complaining.

"In fact, our research institute also planned to make gel batteries, but this time is not a good time to intervene in gel batteries, the people do not recognize this thing at all, and even some authoritative experts in the industry evaluate gel batteries as "profit-driven", you say, in this case, we can compare with this project? ”

This is true, the people are suspicious of the gel battery, which means that the market prospect is not optimistic, and the battery research institute will launch this project again, isn't it uncomfortable for themselves?

"That is, we can only use gel batteries or nickel-metal hydride batteries from the Germans?" Lin Zheng asked, this question is what Lin Zheng cares about.

"That's not it, in fact, after that, we still put a lot of effort into gel batteries in China," although Lin Zheng's decision may have some impact on BYD's future, but out of the friendship between the two people, the boatman still explained to Lin Zheng very neatly, "After the nineties, our domestic research direction has shifted to the correct track of using fumed silica to configure colloidal electrolyte, last year, there are several domestic companies that can produce gel batteries with performance close to the performance of foreign gel batteries, However, because the formula and gel-making process have not passed, the performance of the gel battery produced is not very stable, the capacity and high and low temperature resistance are not very ideal, and the thermal runaway phenomenon often occurs...... However, although there are a lot of messy things, the technical gap between our domestic and foreign batteries is really not big, and there are dozens of patents for gel batteries alone, but they are all missing. ”

"In this way, you can only use nickel-metal hydride or foreign gel batteries?" Lin Zheng was a little unwilling.

"Not necessarily," the boatman muttered, "I heard that Shen Chu is in contact with the German company Hagen...... Well, this Hagen company's technical attainments in gel batteries are comparable to those of Sunshine Company...... Interested in introducing a full set of gel battery technology and equipment from Hagen company, if it is fast, it will probably be able to produce our domestic gel battery next year, if you plan to use gel battery, this should be able to meet your requirements, but I really don't know how the specific situation is, so let me help you ask? ”

"Cheng, I'm in trouble." Lin Zheng was not polite to the boatman.

……………………

The boatman's movements were not slow at all, but he called back in half an hour, "Well, I inquired clearly, the two sides have talked about it, just now Shen Chu also sent a second group of people to Hagen to learn gel battery manufacturing technology, my friend in Shen Chu said, if a qiē shun lì, by the beginning of next year can produce the first batch of real gel batteries in China, as long as the indicators through the guòdin standard testing can be recognized by Hagen company, even customers have been found." ”

Is it going to be 96? Lin Zheng was a little hesitant: it is said that now he can use Hagen's gel battery for research, so he had to produce a qualified gel battery from Shen Chu, and then directly use Shen Chu, but it will not delay things, and the cost is definitely better than buying batteries directly from Hagen or Sunshine Company, but the problem of state-owned enterprises is ...... That's really too strict, if it's the boatman's business, wait a minute, just wait, but Shen Chu? Dude hasn't dealt with them before.

"Lao Wang, tell me the truth, the people over there, do you think they can be trusted?" After a little hesitation, Lin Zheng asked the boatman.

"This ...... How to say that? "Brother boatman suddenly smiled bitterly, on both sides are his friends, on the other side are his partners, if Lin Zheng really used Shen Zheng's gel battery, it is unlikely to be possible to take nickel-metal hydride batteries from his side, but in the same way, he is too clear about the old problems of state-owned enterprises, maybe it will be fine in the first year or two, but who can say for sure what will happen in a few years?" I've heard that their funds are quite tight, and if you can take a stake in Shen Chu, it's not a big problem. ”

Investing in Shen Chu? Lin Zheng was really stunned, he really hadn't thought about this problem before, but listening to what the boatman said, Lin Zheng was a little moved, he really knew too well how big the market for gel batteries would be in China after 2ooo years...... Take a look at the wide variety of electric vehicles running on the streets, almost all of which use gel batteries.

Well? It's a good idea, later generations have heard of Wei and Tianneng, but they don't seem to have heard of Shen Chu, so it means that Shen Chu doesn't seem to have developed later? Realizing this, Boss Lin was moved, "Boatman, why don't you contact your classmates, let's take a stake in Shen Chu together, what do you think?" ”

"Let's take a stake in Shen Chu?" The boatman was also stunned, he really didn't think about this problem, yes, people are now playing nickel-metal hydride, nickel-chromium, and even lithium-ion batteries are in the boatman's 2-year exhibition plan, and the research of lithium-ion batteries has now entered the final sprint stage, and he really looks down on gel batteries in his heart: no matter how gel you are, it's not old lead-acid? But now......
