Abstract

Abstract:

Lithium-ion batteries are rechargeable batteries, the operation of which is dependent on the movement of the lithium ions between positive and negative electrodes. The high-specification and -voltage batteries exhibit various advantages such as good cycle performance, low self-discharge, no memory effect, high specific energy, and environmental protection. Thus, they have become the focus of current energy storage and battery research worldwide. In this study, the patent applications with respect to the geographic distribution of lithium-ion battery packs and the main global patent applicants were sorted based on the analysis of the patent application trends and the technical life cycles of the high-specification and -voltage lithium-ion battery packs. Subsequently, the patent layouts are analyzed to guide the relevant research units to effectively avoid patent disputes and reduce infringement risk in case of research and development. Furthermore, we promote technical innovation in key research and development directions through technical analysis.

Key words: lithium battery, patent analysis, applicants, patent layout
