Abstract

Abstract:

In order to provide advices about technology innovation and industrialization of lithium-sulfur battery for our country, relevant patents applied in China were retrieved from the incoPat platform. The patent profiles were then analyzed with respect to application trend, countries of applicants, main applicants, types of applicants, patent values of main applicants, technical distribution of patents and technical structure of patents. Subsequently, patent portfolio and technical route of important foreign applicants were specifically addressed. Based on the analysis, advices with respect to R&D, patent application and protection of lithium-sulfur battery technology were lay out.

Key words: lithium-sulfur battery, technical route, patent analysis
