In the passage of time, every retrospect and prospect carries countless dreams and strenuous efforts. January 6th, 2025, an otherwise ordinary day, was endowed with extraordinary significance due to the grand convening of Yixinfeng Group's 2024 Annual Summary and 2025 Goals Announcement Ceremony. It has become a glittering memory landmark in the hearts of all Yixinfeng employees.

Against the backdrop of growing energy demands, lithium batteries, as an efficient energy storage device, are attracting significant attention in terms of their performance and cost. The electrode manufacturing process of lithium batteries plays a crucial role in its overall performance and cost. Although the traditional wet coating process has made progress over time, its limitations has become increasingly prominent in the face of ever more stringent requirements. At this point, the dry electrode process has emerged as a new technology, bringing new development opportunities to the lithium battery industry.

In 2024, the "low-altitude economy" has emerged as a dark horse and become a hot topic. Many cities have successively issued relevant policy documents and actively explored its development path, attracting widespread attention. So, what exactly is the low-altitude economy?

In the production process of lithium batteries, slurry coating is a crucial process. Its main purpose is to uniformly coat the slurry with good stability, viscosity, and fluidity onto the positive and negative current collectors, which is of great significance for the capacity, consistency, and safety of lithium batteries. However, according to incomplete statistics, the proportion of battery failures caused by the electrode coating process among all lithium battery failures due to various reasons reaches 10% - 15%.

In the vast expanse of life's long river, we often lose ourselves under the dazzling light of success or struggle painfully in the dark abyss of failure. And the "Empty Cup Effect", like a brilliant star, illuminates the path ahead of us, guiding us towards a profound awakening of the soul and the infinite possibilities of life.

In life, we often contemplate the meaning of hard work. Some people question why we should bother exerting ourselves since effort doesn't always guarantee success. However, the value of hard work cannot be simply measured by success or failure.

Hey, you know what ? When we talk about electric vehicles, power tools and other equipment using power batteries, there is a key technology that plays a huge role behind it, that is, power battery equalization management.

In the current technological era, lithium batteries, as the power source for numerous electronic devices, have crucial performance. The internal resistance of lithium batteries, a parameter often overlooked, actually has a profound impact on battery performance. Today, let's delve into the mysterious world of lithium battery internal resistance.
I. What is internal resistance? What does it consist of?
The internal resistance of a lithium battery is not just a simple number. It is composed of ohmic internal resistance and polarization internal resistance.

Against the backdrop of the global energy structure's profound transformation, the new - energy industry shines brightly. New - energy vehicles run fast and energy - storage equipment offers stable support. The demand for high - performance batteries is surging, strongly pushing battery - manufacturing technology to innovate continuously. Yixinfeng's die - cutting and laminating integrated machine, like a brave knight, injects strong impetus into the new - energy industry with its outstanding performance and ingenious design.

On the stage of the energy sector, energy storage batteries and power batteries are like two brilliant stars, each shining with its unique luster and playing an irreplaceable and crucial role. Although there are certain similarities in technical principles between the two, due to the huge contrast in application scenarios, there are significant differences in performance, lifespan, and many other aspects.
