The battery is equipped with "dragon scales"? A peek into the new technology of Honeycomb Energy Batteries

With the rapid increase in the penetration rate of electric vehicles, the high safety, long battery life, high economy and rapid recharge of electric vehicles have become important selling points for car companies and the main demands of consumers.

2022 is coming to an end, and this year, leading battery companies have also focused on the above-mentioned pain points and continued to iteratively launch new battery solutions, such as CATL Kirin batteries, BYD CTB body batteries, Yiwei Lithium Energy 46 series large cylindrical solutions, etc.

Battery China recently learned that, as a new power battery force that has emerged in recent years and ranked among the world's top 10 camps, Honeycomb Energy will hold the third "Battery Day" on December 15 to release relevant new technologies and products, as well as a new strategic blueprint. .

Recently, Honeycomb Energy has successively released three themed posters related to its Battery Day: "UFO Flying Saucer", "Dragon Scale" and "Honeycomb". If you pay close attention to the posters, you will find that the information on each poster page seems to have a mystery or hidden meaning of Honeycomb Energy. The new black technology products will be revealed on "Battery Day".

01

"UFO flying saucer" points to lamination technology?

In the first poster of Honeycomb Energy, the words "UFO Arrival and Efficiency Take Off" appear, and the image of a flying saucer on the screen is full of imagination. When considered in connection with cellular energy, it is easier to think of ultra-high-speed lamination technology that is representative of cellular energy.

"Dish" is homophonic to "stack", and "efficiency takes off" should directly point to the pain points of lamination efficiency. Combined with the third-generation lamination technology recently released by Honeycomb Energy, this poster may be related to the lamination process.

At present, there are two main manufacturing processes for battery cells: winding and lamination. The winding process is relatively mature and highly efficient, while the lamination process is good for improving battery safety, energy density and cycle. However, the shortcoming is that before lamination The sheet production efficiency is not as good as that of winding.

It is worth noting that last month, Honeycomb Energy officially announced the successful mass production of its independently developed third-generation high-speed lamination technology product. According to reports, the third-generation high-speed lamination technology has achieved a disruptive breakthrough in lamination efficiency, reaching 0.125 seconds/piece, which is more than 200% higher than the second-generation efficiency. At the same time, the equipment unit area has been reduced by more than 40% year-on-year. And the product safety is better, the energy density and production yield rate are higher.

According to Battery China, Honeycomb Energy’s third-generation high-speed lamination technology integrates pole piece unwinding, cutting, lamination CCD online monitoring, and hot pressing functions, shortening the sheet material transfer between pole piece rolls and stacks. It reduces the difference in processing accuracy between pole piece cutting and stacking, and greatly improves the yield rate.

Is the lamination technology that is comparable to or even surpasses the winding process the limit pursued by Honeycomb Energy? And what kind of technology or product will be as efficient as a "UFO flying saucer"? I hope to see the real story at the Honeycomb Energy Battery Day.

“Dragon Scale”, a new technology for power battery safety?

On December 8, Honeycomb Energy released the second poster of Battery Day: "Dragon Scales is now safe and upgraded." Judging from the poster design, many pieces of "dragon scales" build a strong safety barrier, which is reminiscent of the popular movie "Nezha: The Devil Boy Comes into the World", in which dragon scales are called the hardest armor. , the Dragon King used the hardest dragon scales on the dragon clan to make the strongest "Ten Thousand Dragon Armor" for Ao Bing. The texture is indestructible and the security and defense power is very powerful.

When it comes to power batteries, the performance that most requires protection as strong as dragon scales is safety. For many years, domestic battery companies and scientific research experts have been doing relevant research and development and design work around the intrinsic safety, active safety and passive safety of batteries. Several new battery products mentioned earlier have also been designed in terms of safety.

In August this year, a visiting group composed of industry media visited Honeycomb Energy’s battery R&D center and battery cell factory and experienced a series of work done by Honeycomb Energy in terms of battery safety. Especially the fully-charged acupuncture test of its dagger battery: the dagger battery does not catch fire or smoke, and the temperature at the acupuncture point is only 30-35 degrees, which has extremely high safety performance.

In addition to the battery cells themselves, recent vehicles equipped with Honeycomb Energy's L600 lithium iron phosphate dagger battery cells with a capacity of 184Ah have also undergone acupuncture experiments conducted by China Automotive Research Institute using 20mm steel needles that far exceeded the national standard and twice the national standard. 140s high-temperature roasting and fire fire test to continuously heat the outside of the battery pack, as well as heating thermal diffusion test and drop test.

Will this "Dragon Scale" theme poster reveal Honeycomb Energy's new technological or product achievements in power battery safety? Since it dares to compete with "Dragon Scale", how high will Honeycomb Energy take power battery safety? We look forward to it in the future. Take a look at its style on Battery Day.

"Honeycomb", the prototype of the whole industrial chain layout of Honeycomb Energy?

On December 9, the third themed poster of Honeycomb Energy Battery Day "Cellular Layout Controls the Future" was released. In the editor's opinion, this theme has at least two meanings: one is a safe, reliable, and comprehensive layout similar to a honeycomb, and the other is jointly planning the future (development). This theme may point to Honeycomb Energy’s ecological strategic layout in the entire lithium battery industry chain?

Data shows that in the first half of 2022, Honeycomb Energy’s cumulative installed capacity reached 2.6GWh, a year-on-year increase of 160%, ranking among the top ten in the world’s cumulative installed capacity of power batteries. Not only that, this year, Honeycomb Energy has tapped into many heavyweight customers and entered the supply chains of many domestic and foreign mainstream car companies. Orders and production capacity have resonated at the same frequency.

In order to ensure the steady release of production capacity and delivery capabilities, Honeycomb Energy continues to plan a vertically integrated industrial layout this year, completing the layout from the most front-end mineral resources to the most advanced recycling.

In March this year, Honeycomb Energy and BASF Shanshan strategically invested in Yongshan Lithium Industry. The three parties will reach strategic cooperation in industrial capital operation, lithium salt product supply, lithium resource development, etc.; in June, with Yiwei Lithium Energy and Sichuan Energy Dynamics has reached a cooperation to form a joint venture; it has reached a strategic cooperation with Ganfeng Lithium Industry to carry out in-depth cooperation in lithium resources, lithium salt supply and marketing, battery recycling and industrial park construction. On the recycling side, Honeycomb Energy has also established a wholly-owned subsidiary, Tengqingqing Renewable Resources Co., Ltd.

It is worth mentioning that Honeycomb Energy’s Dazhou lithium battery zero-carbon industrial park has also been launched this year. The industrial park will build lithium iron phosphate and cobalt-free cathode material production lines, lithium iron phosphate precursor and electrolyte production lines, and battery recycling and dismantling production lines. , power battery assembly production lines and industry chain related supporting projects to create a honeycomb lithium battery full industry chain park in southwest China.

In addition to the upstream lithium resources, precursors and recycling links, Honeycomb Energy and Honeycomb Capital have also made frequent moves in various links of the industry chain such as cathodes, anodes, electrolytes, copper foil, etc., aiming to build an ecological alliance for the Honeycomb Energy industry.

It should be pointed out that "honeycomb" may have more than this meaning. French scholar Maralchi once specifically measured the dimensions of a large number of honeycombs (honeycombs). What surprised him was that all the obtuse angles of the rhombus that these honeycombs form the chassis of are 109°28′, and all the acute angles are 70°32′. . Later, according to theoretical calculations by French mathematician Koenig and Scottish mathematician Mark Lorraine, it was at this angle that the largest rhombus-shaped container could be made if the least amount of material was to be consumed. In this sense, bees can be called "genius mathematicians and designers."

If we look at the design of a "honeycomb", a honeycomb can also be a precision-designed, highly intelligent power battery factory of the future.

Honeycomb Energy has attached great importance to the construction of automotive-grade power battery factories since its inception. As early as 2019, it took the lead in building automotive-grade smart factories in the industry and continues to innovate and develop AI intelligent applications.

At the beginning of this year, Hive Energy successfully hatched "Dr. Octopus". The latter is positioned as an intelligent control and intelligent manufacturing core system provider. It is divided into two major business segments: hardware and software to support power batteries in five aspects: product planning, technology research and development, process quality, production capacity and customer service system. collaborative innovation.
