Recently, Guangdong Pucoon Technology Co., Ltd. (hereinafter referred to as “Pucoon Technology”) was officially granted an invention patent by the China National Intellectual Property Administration for its self-developed “Cylindrical Cell Production Equipment and Production Process” (Patent No.: ZL 2025 1 1768710.3). The achievement of this technological milestone marks a key breakthrough for Pucoon Technology in the manufacturing precision and consistency of cylindrical cells, while also providing solid technical support for the reliable upgrade of lithium batteries.

Targeting Industry Pain Points with Patented Technology for Precision Cell Assembly

In the market for two- and three-wheeled electric vehicles, cylindrical lithium batteries are becoming one of the mainstream power options due to their high standardisation, excellent consistency, and flexible grouping capabilities. However, issues such as shell positioning deviations and uneven assembly stress during cell production directly affect internal resistance, cycle life, and even safety performance.

The invention patent recently granted to Pucoon Technology offers an innovative solution to these very challenges. The patented equipment features a unique centering clamping assembly design—multiple sets of correction rods, driven hydraulically, achieve relative movement and longitudinal extension, enabling full‑scale centering and uniform pressure application to the shell, ultimately positioning the cell shell precisely at the centre of the mounting table. Meanwhile, the mounting table surface adopts an obstruction‑free layout, allowing operators to place the shell quickly without having to deliberately avoid components, greatly improving workflow efficiency.

The direct value of this technology lies in a marked improvement in the positional accuracy and pressure uniformity of cell assembly, resulting in a more stable fit between the electrode assembly and the shell. This reduces internal resistance fluctuations and enhances the overall consistency of battery packs. For end users, this means that two‑ and three‑wheeled electric vehicles equipped with Pucoon Technology’s cylindrical cells will enjoy smoother power delivery, longer range and service life, and higher charge/discharge safety.

R&D Strength Reinforces Product Foundation, with Continued Focus on the Light‑Duty Power Track

Pucoon Technology has long been dedicated to the R&D and manufacturing of lithium batteries for two‑ and three‑wheeled electric vehicles, accumulating extensive experience in cell sorting, module PACK, system integration, and other stages. The acquisition of this invention patent represents another self‑transcendence by the company’s R&D team in core process equipment.

This technology has been progressively integrated into Pucoon Technology’s existing cylindrical cell production lines and works in synergy with the company’s automated inspection and data traceability systems. From a single cell to the complete battery pack, every process step is designed to be precisely controlled, delivering a quality assurance that customers can rely on.

Driving the Future through Innovation – Every Cell Worthy of Trust

Intellectual property serves as authoritative proof of technological strength. The granting of this invention patent not only affirms Pucoon Technology’s spirit of innovation but also reinforces the company’s determination to continue investing in fundamental process research. In response to the growing quality demands of the lithium battery market for two‑ and three‑wheeled electric vehicles, Pucoon Technology will adhere to its development path of “technology‑first, application‑centric”, continuously optimising cell production equipment and processes to provide vehicle manufacturers and end users with cost‑effective power solutions that offer longer cycle life.
