Abstract

The work aims to understand the current status of patent applications in the field of protective packaging for lithium battery transportation, study the development trend and technical characteristics of the industry of protective packaging for lithium battery transportation, and provide theoretical basis for further optimizing product design and expanding innovation directions. Based on the IncoPat patent database, the patent application volume and the characteristics of major applicants were analyzed, and the technical means and protective effects of packaging design were discussed from the aspects of the main materials, structure, and special protective function design of packaging for lithium battery transportation. In recent years, the volume of patent applications in the field of protective packaging for lithium battery transportation continued to increase, and China ranked first in the world in terms of the volume of patent applications in this field. The main materials of packaging for lithium battery transportation were innovated towards lightweight and functionalization. The packaging structure was improved in terms of stacking stability, buffering and shock absorption, content fixation, and space utilization. Special protective functions such as fire retardancy and anti-static shifted from passive suppression to active intervention and multi-angle systematic protection. The protective technology and packaging for lithium battery transportation have broad development prospects and will develop towards material innovation, functional integration, and system intelligence in the future.
