In the era of rapid progress in new energy vehicles, lithium-ion batteries, as their core power source, directly determine the cruising range, safety and overall competitiveness of new energy vehicles through their performance. As a rechargeable secondary battery, lithium-ion batteries are widely used in fields such as electronic information, electric vehicles, and smart grids due to their characteristics of high specific energy, high working voltage, long cycle life, and small size.

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 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 deep roots firmly planted in the soil; no great man can succeed without the accumulation of efforts made during obscurity; no successful enterprise can rise without a solid and profound foundation; no industry giant can be born without the devoted precipitation during anonymity. All the glorious upward take-offs originate from the persistent downward rooting.

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. 

On June 18, 2024, Yixinfeng will debut at Battery Europe. This is a high-profile international event that attracts many companies and professionals in the battery industry around the world. As a leading enterprise in China's battery equipment manufacturing field, Yixin Feng will display its latest technology and products in Stuttgart, Germany, and show the strength and style of China's battery industry to the world.

In the wave of technology, Yixinfeng is going to embark on the journey of Battery Europe and EV Technology Show 2024, which is an excellent opportunity to showcase innovation and technology, and an important platform to communicate and cooperate with global industry leaders. We sincerely invite you to witness this wonderful moment together!
