　　The technical route is quite distinctive. Interpretation of honeycomb button battery cr1620 technology

　　honeycomb? What we want to talk about today is not express cabinets, but battery packs used in new energy vehicles. Yes, today we are here at Honeycomb Energy Technology, and we also visited the Honeycomb Energy Changzhou Jintan Factory that just started construction. There are still a lot of black technologies.

　　■What is the origin of hive energy?

　　Honeycomb Energy Technology Co., Ltd. has a deep relationship with Great Wall Motors. It is actually the original power battery division of Great Wall Motors. It became independent in 2018, so Great Wall's new energy models such as the Euler R1 use Honeycomb Energy's battery packs. .

　　It is worth mentioning that Honeycomb Energy owns the entire battery industry chain, that is, battery materials, cells, modules, PACK (battery packs) and BMS battery management systems, as well as related energy storage and solar energy development businesses.

　　*Only domestic production and R&D? NO! Multiple R&D centers around the world

　　Although it has not been independent for a long time, thanks to its long-term layout, Honeycomb Energy's R&D centers in Baoding, Shanghai, South Korea, and India have been put into use. In the future, there will also be R&D centers in the United States, Japan, and Wuxi.

　　At the production level, the Changzhou Jintan factory with a total production capacity of 18GWh is about to be put into production, and the production capacity is expected to reach 12GWh in 2020.

　　At the technical level, Honeycomb Energy still has many technical highlights:

　　■What are the benefits of the battery platform?

　　Honeycomb Energy has created its own battery technology platform, and with the help of the platform, it can achieve various functions:

　　Each type of vehicle has its own needs.

　　Using different positive and negative electrode materials to achieve battery energy density suitable for different scenarios

　　For example, short-distance transportation vehicles use battery materials whose costs are easier to control - such as cobalt-free and high-nickel cathode materials. Although the energy density is not that high, it can meet the positioning needs of the vehicle.

　　Standardization and compatibility

　　Standardization can first reduce costs and increase market competitiveness. Secondly, it can make battery products suitable for different models of different brands. In the future, it is expected to realize cooperative development of different brands, which is very beneficial to reducing costs, especially when subsidies are declining. more effective under the circumstances.

　　Better security

　　Due to its more flexible shape, the new battery platform based on prismatic cells can create longer and thinner battery packs, which is beneficial to the design of the vehicle and leaves more space for the battery safety structure.

　　■What are the main products of the Changzhou factory?

　　High-speed laminated square batteries are well-known in the industry

　　Currently, there are three types of mainstream batteries (cells) on the market: cylindrical hard-shell, square hard-shell and soft-pack batteries. Honeycomb Energy’s main focus is square hard-shell batteries, which can currently reach an energy density of 260-300Wh/kg.

　　Honeycomb Energy's high-speed laminated square battery is a well-known product in the industry. Compared with rolled batteries, its energy density is increased by 5%, its cycle life is increased by 10%, its cost is reduced by 5%, and it is safer.

　　Although it has not been independent for a long time, thanks to its long-term layout, Honeycomb Energy's R&D centers in Baoding, Shanghai, South Korea, and India have been put into use. In the future, there will also be R&D centers in the United States, Japan, and Wuxi.

　　*What are the other benefits of laminated square batteries?

　　Greater charging and discharging power

　　Higher charging and discharging power means faster charging and shorter charging time. On the other hand, it has better smoothness during energy recovery. Combining the two aspects, the user experience is better.

　　■Highly automated and intelligent Changzhou Jintan Factory

　　In terms of intelligence, Changzhou Jintan Factory adopts the world's most advanced battery automation production equipment, with an automation rate of 95%. Among them, the three production lines configured in the assembly workshop all adopt the "Industry 4.0" design concept, with an automation rate as high as 100%, which is safer and more efficient to meet the balanced production of multiple types of battery products; the entire line automation rate in the formation workshop is also As high as 99%, the module factory automation rate has also reached 91.6%.

　　*New technology improves production efficiency

　　Due to structural limitations, the production efficiency of laminated batteries is currently not as good as that of rolled batteries. However, through process improvements, Honeycomb Energy will reach production efficiency equivalent to that of rolled batteries in the future.

　　■What other cutting-edge technologies are there?

　　In today's era where you will fall behind if you don't study for three days, Honeycomb Technology has "secretly" made a lot of cutting-edge technology reserves:

　　High nickel battery cathode, better stability;

　　Quaternary cobalt-free battery, lower cost (cheaper without cobalt...);

　　Solid-state battery, energy density exceeds 400Wh/kg, battery life is expected to exceed 750 kilometers!

　　Graphene battery has better stability;

　　Wireless BMS has a simplified structure and good scalability.

　　Conclusion: Honeycomb Energy uses square cells as its main battery type, and its lamination process is also quite distinctive. In addition, the entire power battery industry chain, especially BMS, has also taken a distinctive technical route, and it is possible to break into a new world in the fiercely competitive domestic battery market.
