  • Excel 文件 + 在線數據庫 12,300 個專利家族
  • 已公佈專利的時間序列轉變、專利申請國等知識產權趨勢
  • 主要專利權人排名
  • 知識產權領域的新進入者
  • 供應鏈專利分類(負極材料、負極、黏合劑、電解液、電芯等)
  • 主要參與者的知識產權定位和專利組合的相對實力
  • 目前主要技術途徑

  • Excel 數據庫,包含報告中分析的所有專利(包括專利類別和最新在線數據庫的超鏈接)

KnowMade 分析師已對 24,700 多個與硅負極鋰離子電池(電極材料、電極、電解質、電池芯)供應鏈相關的專利族(發明)進行分類,我們選擇並分析了專利和專利申請。我們還確定了 1,800 多個涉及矽負極專利的不同專利權人。在全球範圍內獲得的專利中有很大一部分反映了鋰離子電池的矽負極技術已經在一定程度上成熟,正在被工業界採用。一方面,許多專利申請仍在等待中,這意味著解決矽負極電池技術問題的研發仍在進行中。

供應鏈中的主要 IP 參與者和新 IP 進入者

本報告概述了最積極申請專利的公司以及新進入該領域的公司。此外,專利細分明確了專利權人對每個供應鏈環節(負極材料、電極、電池芯)的定位、矽負極材料的主要專利(形態、成分、製造工藝)以及近期專利發展的重點。最重要的是,我們專注於中國的初創公司和生態系統。

直到 2010 年代上半年,矽陽極的專利由日本公司(日立化成、昭和電工、三井物產、松下/三洋、索尼、NEC、豐田等)和韓國兩大電池公司頒發公司(LG Chem、Samsung)雖然被壟斷,但中國公司的知識產權活動自2015年以來呈指數級增長,如今已佔專利的45%。

中國的IP領導者是ATL、Guoxuan High-Tech、CATL、Shanhan Energy、COSMX、SVOLT、New Keli Chemical、EVE Energy、Yinlong Energy。只有歐洲(Bosch/Seeo、Nexeon、CEA)和美國(Global Graphene、General Motors、Enevate、Amprius)擁有鋰離子電池矽陽極的專利,只有少數日本公司沒有。三大汽車製造商豐田、通用汽車和日產擁有多項專利。

在過去幾年中,包括許多初創企業在內的 170 多家公司已進入該領域。QingTao Energy Development、Sila Nanotechnologies、StoreDot、Wildcat Discovery Technology、Battflex、Coreshell Technologies、3DBattery、QuantumScape、AnteoTech、Enwires、Blue Current、Graphenix Development、Cenate、SilLion(被Tesla收購)、OneD Materials、Enevate、Amprius、Nexeon、Nanospan、NanoGraf、Group14 Technologies、Qnovo

How have industry leaders and start-ups positioned their pawns to address the glorious potential of silicon anode-based Li-ion batteries?

Report's Key Features:

  • PDF with > 180 slides
  • Excel file + Online database > 12,300 patent families
  • IP trends, including time evolution of published patents and countries of patent filings.
  • Ranking of main patent assignees.
  • Newcomers in the IP landscape.
  • Patent categorization by supply chain segments (anode materials, anode, binder, electrolyte, battery cell, etc.).
  • IP position of key players, and relative strength of their patent portfolios.

Knowmade's analysts have selected and analyzed more than 24,700 patents and patent applications grouped in more than 12,300 patent families (inventions) related to the whole supply chain of silicon anode-based Li-ion batteries (electrode materials, electrodes, electrolytes, battery cells). We have identified more than 1,800 different patent assignees involved in the Silicon anode patent landscape. The significant proportion of patents granted worldwide reflects a certain maturity of silicon anode technology for Li-ion batteries which is now being adopted by the industry. Nevertheless, numerous patent applications are still pending, meaning that R&D developments are still ongoing to solve technical issues related to silicon anode batteries

Leading IP players and IP newcomers across the supply chain

The report provides a clear overview of the most active patent applicants as well as a presentation of newcomers to the patent landscape. Furthermore, patent segmentation reveals the IP position of patent assignees by supply chain segments (anode material, electrode, battery cell) and highlights their key patent and recent IP developments for silicon anode materials (morphologies, compositions, manufacturing processes). Special attention has been paid to start-ups and Chinese ecosystem.

The silicon anode patent landscape was dominated by Japanese entities (Hitachi Chemical, Showa Denko, Mitsui, Panasonic/Sanyo, Sony, NEC, Toyota, etc.) and the two major South Korean battery companies (LG Chem, Samsung) until the early 2010s, but the IP activity from Chinese entities has exploded since 2015, representing today 45% of the patents.

The Chinese IP leaders are ATL, Guoxuan High-Tech, CATL, Shanshan Energy, COSMX, SVOLT, New Keli Chemical, EVE Energy and Yinlong Energy. Only a few Europeans (Bosch/Seeo, Nexeon and CEA) and Americans (Global Graphene, General Motors, Enevate and Amprius) have patents on silicon anodes for Li-ion batteries. The three main car manufacturers Toyota, General Motors and Nissan are present in the IP landscape.

We have identified more than 170 IP newcomers entering the patent landscape the last few years, including numerous start-ups: QingTao Energy Development, Sila Nanotechnologies, StoreDot, Wildcat Discovery Technology, Battflex, Coreshell Technologies, 3DBattery, QuantumScape, AnteoTech, Enwires, Blue Current, Graphenix Development, Cenate, SilLion (acquired by Tesla), OneD Materials, Enevate, Amprius, Nexeon, Nanospan, NanoGraf, Group14 Technologies, Qnovo, etc.

Focus on key players' patent portfolios

The report provides a detailed analysis of 17 key IP players and most promising IP newcomers: Samsung, LG Chem/LG Energy Solution, Panasonic/Sanyo, Murata/Sony, CATL, SVOLT, Toyota, Hitachi Chemical/Showa Denko, Shin-Etsu Chemical, Mitsubishi Chemical, BTR New Energy Material, Shanshan Energy, Nexeon, Amprius, StoreDot, Global Graphene, Guoxuan High-Tech. For each player, we summarize their IP portfolio, unveil their IP strategies by analyzing their key patents and recent IP developments.

Understand the technological trends

The patents have been categorized by supply chain segment (anode material, anode, binder, electrolyte, battery cell. The report comprises specific parts dedicated to silicon anode materials, silicon anode and battery cell, in which the key IP players, IP newcomers, key patents and recent IP development related to are analyzed. In this report, Knowmade highlights the main silicon-based materials which are envisioned in patents to improve the cyclability and electrochemical performances of silicon anode materials, increase the yields and reduce the cost and environment impact of the material synthesis.

Useful Excel patent database

The report also includes an Excel database with the 12,300+ patent families (inventions) analyzed in this study. This useful patent database allows for multi-criteria searches and includes patent publication numbers, hyperlinks to an updated online database (original documents, legal status, etc.), priority dates, title, abstract, patent assignees, patent's current legal status, and segments (anode material, anode, binder, battery cell, electrolyte, equipment, etc.).
