電池用LiMxMn2-xO4正極材料之專利趨勢：2011年 是由出版商France Innovation Scientifique et Transfert (FIST SA)在2011年04月所出版的。
這份英文市場調查報告書價格從美金6860起跳。
尖晶石結構鋰錳氧化物（LiMn2O4）於90年代初期，以LiCoO2（鋰鈷氧化物）正極之主要替代物研發至今。但因成本低，即使錳較鈷更易於環保，能源密度低及能力下降仍限制了其潛在應用，使市場難以普遍地接受。為克服錳溶解帶來之能力下降，並改善其容量、能源密度、速度等，目前進行了許多研發。
本報告為，調查電池用LiMxMn2-xO4正極材料之專利趨勢，並提供技術概要、全球市場分析、地區別趨勢、主要申請企業資訊等，以下列摘要形式闡述。

Abstract
Description/Summary
IP Overview presents a patent mapping analysis of the "LiMxMn2-xO4 cathode
materials for batteries" field. Spinel lithium manganese oxide (LiMn2O4)
has been investigated since the early 90' s as one of the most serious
alternative to the LiCoO2 cathode. Despite the low-cost and low impact on the
environment of Manganese versus Cobalt, lower energy density and capacity
fading have however limited its potential applications and wide market
acceptance. This capacity fading being due to the dissolution of manganese,
significant R&D has been performed in order to improve capacity, energy
density and rate capability. The substitution of Manganese by several dopants
has been investigated as well as the coating of the cathode by different
active materials and the use of specific anode materials (commercially LTO)
and electrolytes. In particular, LiNi0.5Mn1.5O4 and derivatives has been
investigated as a promising candidate for a 2015-2020 high energy density 5V
cells. With the expiry or near expiry of the historical patents (like the
Panasonic 1989 JP3219571), younger portfolio emerges and acquires a blocking
position (like the ones among others from Tosoh Corp and Japan
Storage Battery, now GS YUASA). Facing the Japanese patent
monopoly, emerging institutional players arise in China, US and Europe. The
present report analyses the patent environment and notably highlights the
strategy of current major players which are not necessarily the major patent
holders. These major patent holders are end-users (Samsung, Sony,
Mitsubishi, LG, NEC, Panasonic), battery manufacturers (Japan Storage
Battery, Yuasa Battery, NGK Insulators, Denso Corp, Shin Kobe electric,
Sanyo) and material manufacturers (Mitsui Mining Smelting, Sumitomo
Metal Mining, UBE Industries, Nippon Chemical, Tosoh Corp).
In a competitive sector where over 900 patents and patent applications have
been filed, this « IP Overview - LiMxMn2-xO4 cathode materials for
batteries » provides you with a comprehensive panorama of the
intellectual property landscape and helps you:
- Position your company' s R&D and IP Portfolio
- Identify key inventors and key players involved in specific doping
compositions
- Understand the collaboration networks and theirs dynamics
