Batteries, also known as mobile energy storage devices. With the development of human civilization to the present, the application range of batteries is becoming more and more extensive, and almost all mechanical instruments and digital equipment are inseparable from this thing.

Due to the needs of environmental and technological development, modern society has higher and higher requirements for batteries, taking the current electric vehicle as an example, due to the battery life, resulting in an electric vehicle facing a situation that is not up or down. The same situation has occurred in portable digital products, where energy consumption is increasing, and batteries have not been developed accordingly, which greatly disrupts the user experience.

In the military field, large-capacity mobile energy storage plays a vital role in individual equipment, weapon systems, and military vehicles. Today, the global technology leadership of fuel cells and lithium-ion batteries has been established, and new battery designs such as lithium-air, lithium-sulfur, solid-state, and zinc-air can increase energy density by a factor of 10, but most of them are still in the early stages of development, and it will take time for them to be widely adopted.

And the cost of lithium-ion battery technology is still somewhat high, and experts in the field hope to reduce the cost of most batteries to less than $200 kWh by 2030, compared to $409 kWh.

The most critical performance indicator of a battery is, of course, energy density. That is, the amount of energy that can be contained in a unit volume – is a key criterion for testing whether a certain battery can be accepted by the market.

With today's technology, any battery that can fit into an airplane can't hold enough energy to lift the plane off the ground. Specifically, jet fuel provides 43 times more energy than batteries of the same weight.

For truly manned electric aircraft to emerge, and for batteries to play a dominant role in small aircraft, they need to be at least five times the current energy density. At the current rate of 5 to 8 percent per year increase in battery energy density, it may not be possible until 20 years from now. At the current rate of development of battery and electric engine technology, it is unlikely that even hybrid technology will be used in commercial aviation in 2030.

But in the apocalyptic world, long before the catastrophe, pure electric vehicles have been very popular, including those heavy combat vehicles, radar early warning equipment, laser weapons of different calibers, armed \ straight \ helicopters, etc., basically rely on high-density batteries to provide energy.

And its volume and weight can be made very small, good safety, ordinary products, its cost is already very low, as for the most high-end products, the energy density is about four times higher than aviation fuel,

It is said that at the top of Kunlun, there are large long-range combat aircraft with pure electric power, but Qin Feng has not seen it with his own eyes.

In order not to trigger too violent market reactions, the battery technology he came up with this time is only about 15 to 20 years ahead of the mainstream products on the market, which is almost equivalent to what is being studied in the top-secret laboratories of several major powers.

All kinds of raw materials required can be found in the main world, as for the production and processing equipment, most of them can also be manufactured by suitable manufacturers in the main world, and a few core equipment are obtained by Qin Feng from the doomsday world. In addition, the production process, employee guidance and training manuals and other materials have also been prepared.

In order to make new products come out as soon as possible, Su Yulan acquired two battery manufacturers that were in a recession, and then merged and reorganized, the new company was named Kun and Rium Technology, and carried out a comprehensive rectification of the original management, recruited new people, improved the management model, installed and debugged new equipment, upgraded production lines, etc., all aspects of things, every one of them had to be taken care of in place, and both of them were busy with their feet on the ground.

Fortunately, with the help of my cousin's network and the help of several partners, all the problems were solved in a timely and smooth manner, and more than a month later, the first batch of brand new mobile phone batteries came out.

In order to let the product enter the market as soon as possible, Qin Feng used some gentle and subtle means to persuade them to sign a cooperation agreement with Kun and Rium Technology when he interviewed the CEOs of several well-known mobile phone equipment manufacturers in China, and as long as the market performance of the new battery meets expectations, a long-term supply contract can be signed in the future.

When the first mobile phones with new batteries entered the market, they quickly caused a great response from users. On major well-known forums and post bars in China, as well as on promotion platforms such as Weibo, WeChat, and Penguin, there are people everywhere talking about this topic:

“…… It's incredible that a newly bought mobile phone has been playing games for seven or eight hours in a row, and there is still a battery left. ”

“…… In the same way, my friends and I went on a business trip to the northwest, and we took turns watching high-definition movies and videos for more than ten hours on the train, and the battery was still half left. ”

“…… Well, my Samsung mobile phone in the past will heat up and get hot after using it for a while, and I am a little worried that it will explode, but I feel much better in this aspect after changing to a new domestic mobile phone. ”

“…… And the charging speed is also super fast, it can be fully charged in half an hour at most, which is really convenient. ”

“…… I heard that it is because the mobile phone manufacturer has adopted a new type of battery, and I feel that the price has not changed significantly, and if its performance is stable enough, I believe that users will be very happy to accept it. ”

“……”

The praise was used like a tidal wave, although there were a few voices of skepticism, which were quickly drowned out without a trace. After all, the quality of this thing really doesn't have to be said. Even in the harsh environment of the apocalyptic world, stable performance can be guaranteed, and there is no need to worry about problems in the overworld, as long as the production link is well controlled.

Now in 2024, Huaguo's smartphone users are close to the billion level, and tens of millions of users change their mobile phones every year, you can imagine what a huge market this is, as long as half of the domestic mobile phones in the future use the new batteries produced by Kun and Dium Technology, the amazing income will make this new company a giant in the industry.

And this is only the first step, in the future, Kun and Dium Technology will continue to launch more kinds of new products, following the digital products, the most important thing is the power battery, imagine a full charge, can drive thousands of kilometers on the highway car, you can infer how popular it will be.

The advent of new products has also attracted the attention of some high-tech giants in the industry, and many bigwigs have held secret meetings to discuss the possibility of acquiring new product technology or cracking it, and more modestly, they hope to cooperate with Kun and Rium Technology.

Their efficiency was quite high, and within a few days, someone came to the door and asked for an interview with Qin Feng.
