EVE Energy Co., Ltd. has recently been granted a utility model patent for a “Roller Pressing Device and Battery Production Equipment,” as reported by Tianyancha APP. The patent application number is CN202421662555.8, and it was authorized on May 9, 2025.
The patent summary describes a roller pressing device that comprises a slurry coating mechanism, a storage belt mechanism, and a pressing roller mechanism. The slurry coating mechanism is designed to apply slurry to the sides of the electrode plates. The storage belt mechanism is intended to supply material to the slurry on the electrode plates. The pressing roller mechanism serves to tightly press the material and slurry onto the electrode plates. This mechanism consists of two parts: the first part has a larger diameter than the second part. The first part is responsible for pressing the slurry located near the center of the electrode plate, while the second part handles the slurry near the edges.
When the electrode plate is subjected to the pressure from the pressing roller mechanism, the center experiences greater force compared to the edges. This design ensures that even if excess slurry is applied on the electrode plate, the pressing mechanism effectively combines the slurry and material with the electrodes, thus preventing issues such as material breakage during the rolling process.
Since the beginning of this year, EVE Energy has obtained a total of 217 patents, which is a 30.23% decrease compared to the same period last year. According to the company’s financial report for 2024, it invested 2.942 billion yuan in research and development, marking a 7.71% year-on-year increase.
