摘要

本综述重点介绍利用锂金属和固体电解质的固态电池(SSB)这一前景广阔的技术。固态电池在高能量密度和增强安全性方面具有显著优势。本综述将固态电解质分为四类:聚合物固态电解质、氧化物固态电解质、混合固态电解质和硫化物固态电解质。每一类都有自己独特的特点和优势。通过探讨这些不同的类别,本综述旨在阐明材料的多样性及其对固态电解质技术进步的贡献。为了深入了解最新的技术发展,并确定加快固态电解质进步的潜在途径,本综述研究了与固态电解质有关的知识产权状况。因此,本综述重点关注该领域主要公司最近申请的固态电解质技术专利,这些公司是根据其在电池领域的贡献和影响力选出的。对专利申请的分析是通过 Espacenet 数据库进行的。丰田、三星和 LG 与 SSB 相关的专利数量非常重要;它们代表了 3400 多项专利,相当于全球 SSB 领域专利产量的 2/3。除了关注这三家著名公司外,我们还通过分析 100 项专利关注了其他 15 家公司。本综述旨在全面介绍各公司在固态电池技术领域所采用的战略,在应用研究和学术研究之间架起一座桥梁。本综述中介绍的一些技术已经实现了商业化,当然,在未来几年中,固态电池的产业化进程将会加快。

An Industrial Perspective and Intellectual Property Landscape on Solid-State Battery Technology with a Focus on Solid-State Electrolyte Chemistries
This review focuses on the promising technology of solid-state batteries (SSBs) that utilize lithium metal and solid electrolytes. SSBs offer significant advantages in terms of high energy density and enhanced safety. This review categorizes solid electrolytes into four classes: polymer, oxide, hybrid, and sulfide solid electrolytes. Each class has its own unique characteristics and benefits. By exploring these different classes, this review aims to shed light on the diversity of materials and their contributions to the advancement of SSB technology. In order to gain insights into the latest technological developments and identify potential avenues for accelerating the progress of SSBs, this review examines the intellectual property landscape related to solid electrolytes. Thus, this review focuses on the recent SSB technology patent filed by the main companies in this area, chosen based on their contribution and influence in the field of batteries. The analysis of the patent application was performed through the Espacenet database. The number of patents related to SSBs from Toyota, Samsung, and LG is very important; they represent more than 3400 patents, the equivalent of 2/3 of the world’s patent production in the field of SSBs. In addition to focusing on these three famous companies, we also focused on 15 other companies by analyzing a hundred patents. The objective of this review is to provide a comprehensive overview of the strategies employed by various companies in the field of solid-state battery technologies, bridging the gap between applied and academic research. Some of the technologies presented in this review have already been commercialized and, certainly, an acceleration in SSB industrialization will be seen in the years to come.
