Hello, all you battery manufacturing experts! Today, we are going to discuss a significant challenge in lithium battery production - the "thick edge" occurrence in negative electrode coating. This "thick edge" is like a mischievous imp, constantly making trouble during the production of lithium batteries and severely impacting the quality and production efficiency. Now, what exactly is this "thick edge"? Don't be impatient. Let me tell you in detail.

In the energy field of today, lithium batteries, with their advantages of high energy density and long lifespan, have become the preferred power source for numerous electronic products and electric vehicles. And the remarkable performance of lithium batteries is inseparable from advanced production processes and core equipment.

n the production process of lithium batteries, the coating stage is crucial. However, various faults often occur during the coating process, affecting production efficiency and product quality. Today, let's take an in-depth look at 25 common faults and solutions in lithium battery coating.(Lithium - Ion Battery Equipment)

n the manufacturing process of lithium-ion batteries, there are usually several ways to divide the process. The process can be divided into three major processes: electrode manufacturing, assembly process and cell testing (as shown in the figure below), and there are also companies that divide it into pre-winding and post-winding processes, and this demarcation point is the winding process. Because of its strong integration function, can make the battery appearance initial molding, so the winding process in the lithium-ion battery manufacturing as a pivotal role, is the key, the winding process produced by the rolled core is often referred to as the bare battery cell (Jelly-Roll, referred to as JR).

n Guangzhou, a city full of vigor and innovation, Asia Pacific Battery Show is like a shining pearl, attracting the attention of the global battery industry. In this exhibition, Yixinfeng, with its amazing new products, like a bright new star, focused countless eyes, and many customers were deeply attracted and stopped at its booth.Lithium - Ion Battery Equipment.

Wow, partners in the battery industry, a shocking, subversive technology feast is about to kick off in Guangzhou! The shocking news is coming, Yixinfeng is ready to bring a series of amazing new equipment to the Asia Pacific Battery Show in Guangzhou.Lithium - Ion Battery Equipment

In the corporate culture of Yixin Feng, the concept of continuous learning is like a brilliant pearl, shining brightly. Just as demonstrated by the personal practice of Mr. Wu Songyan, the founder of Yixin Feng, only through continuous learning can we get rid of mediocrity. 

No big tree can grow without deeply rooted roots in the land; no great man's success can be separated from the accumulation of efforts during obscurity; no rise of a successful enterprise can be separated from a solid and profound foundation; no birth of an industry giant can be separated from the devotion and precipitation during obscurity. All the glories of upward take-off originate from the persistent downward rooting. 

This device combines the functions of laser cutting, winding and flattening at the same time, and can realize various tab tests. It can be imported with one click and the model can be changed quickly. Its emergence has completely changed the limitations of traditional battery manufacturing equipment and provided an efficient, accurate and reliable solution for battery production enterprises.

Recently, Yixin Feng shone brightly at the Battery Show in Europe and concluded perfectly with outstanding performance. It achieved remarkable achievements in its first participation, and this milestone event marks that the company has entered a new stage of development. During the exhibition, the Yixin Feng team won high praise from foreign friends with its strong strength, exquisite technology and excellent product craftsmanship. This exhibition not only opened the door to the European new energy market for the company, but also laid a solid foundation for its future development.
