鋰離子電池矽負極專利情況分析(2022)Silicon Anode for Li-ion Batteries Patent Landscape 2022 |
本報告重點關注鋰離子電池矽負極,包括分析主要IP趨勢、主要專利技術、近期發展趨勢、主要IP公司/新進入者,以及IP戰略/材料優勢。
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。
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
本報告詳細分析了 17 個主要知識產權參與者和最有前途的新進入者。三星、LG化學/LG能源解決方案、松下/三洋、村田製作所/索尼、CATL、SVOLT、豐田、日立化成/昭和電工、信越化學、三菱化學、BTR New Energy Material、Shanhan Energy、Nexeon、Aprius、StoreDot、Global Graphene、Goxuan High-Tech等各個玩家,我們將通過分析主要專利和近期IP發展,總結IP組合,明確IP戰略。
專利屬於供應鏈環節(負極材料、負極、粘合劑、電解質、電池)。本報告由矽陽極材料、矽陽極和電池單元組成,分析了主要的知識產權參與者、新的知識產權進入者、主要專利和最近的知識產權發展。在這份報告中,Knowmade 對專利中設想的主要矽基材料,以改善矽負極材料的充電/放電循環特性和電化學性能,提高良率,降低材料合成成本和環境負擔等方面進行了高度重視。
此外,本報告附有一個 Excel 數據庫,其中包含本研究分析的 12,300 多個專利家族(發明)。這個方便的專利數據庫可以通過多種方式進行搜索。 Excel 數據包括專利公開號、最新在線數據庫的超鏈接(原件、法律狀態等)、優先權日期、標題、摘要、專利權人、專利的當前法律狀態、細分(負材料)。底片、活頁夾、電池電池、電解質、設備等)都包括在內。
How have industry leaders and start-ups positioned their pawns to address the glorious potential of silicon anode-based Li-ion batteries?
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
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.
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.
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.
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.).
