1. 研究開発の内容及び成果等
(1) 負極材・集電材の研究開発
a)金属酸化物の適応と負極材/集電材の基礎研究(岩手大学)
炭素に代わる新たな負極材として、スピネル型Li4Ti5O12(チタン酸リチウム、LTO)を合成し、X?線解析その他の方法によって、結晶構造などの基礎的な特性を確認した。コインセル評価によって、容量は150mAh/g 以上(理論値175 mAh/g)であることが確認された。
英文要約Title: Technology Development of Energy Storage System to Facilitate Interconnection of Renewable Energy to Power Grid/Element technology development/
Research and Development about High Efficiency / Low Cost of Energy Storage System for New Energy and Electric Power Application which used Lithium-Ion Battery(Practical use technology development)(FY2006-FY2007)FY2006 Annual Report
(1) Preliminary Study on the advanced anode materials and combined collecting materials
a) Fundamental research about adaptation of metal oxide, cathode material and corrent collector(Univesity of IWATE)
As new cathode materials for carbon, I composed spinel type Li4Ti5O12( titanic acid lithium, TLO) and, confirmed fundamental characteristics of crystal structureby methods such as X - line analysis .As for the capacity, it was confirmed that it was more than 150mA/g(theory value 175mA/g) by coin cell evaluation.We made an evaluation cell to change conventional copper foil to cheap and lightweight aluminum foil about combined collecting materials.
b) Study of cathode active material having low cost, mass production characteristics and high quality battery characteristic(KUSAKA RARE METAL product Co.,LTD)
Instead of conventional solid-phase law and crush, I developed LTO by "organic acid salt method" which assumed the reaction refinement thing of carboxylic acid and a titanium chloride a precursor newly.As fundamental examination, I tested it about the Li/Ti mol ratio, molecular weight of carboxylic acid and burning temperature (600-900 degrees Celsius).
c) Preliminary Study on the advanced anode materials and combined collecting materials.(ENAX Co., Ltd.)
With information and an offering of a prior sample from IWATE University and KUSAKA RARE METAL Ltd. , we evaluated alkalinity (pH after the inundation) of quality of flower arrangement, electrolyte system and the choice of Li salt and trial manufacture and charge and discharge of a cell.
(2) Study on anode materials
a) Development of the advanced LMO/lithium manganese oxide cathode material and LIP/lithium iron phosphate cathode material (Univesity of FUKUI)
Instead of conventional solid-phase law and crush, We develop LMO by "an aerosol process" to atomize a precursor water solution with a high temperature atmosphere. A sample of average particle size 9μm and 18μm was provided for conventional examination and confirmed crystallization by X - line diffraction.
b) Study of anode active material having low cost, mass production characteristics and high quality battery characteristic(KUSAKA RARE METAL product Co.,LTD)
We composed a carboxylic acid Mn precursor to offer in "aerosol - lithium coating method" and confirmed that it was quality of object from X - line analysis after 500 degrees Celsius burning.
c) Preliminary study on the advanced cathode materials and related electrolyte.(ENAX Co., Ltd.)
About olivine-type LIP, we observed particle size distribution by SEM observation and made an extra cell.
(3) Prementary study for for the high-performance and long-life battery system
a) Basics evaluation of materials characteristic and the choice of materials concerned(ENAX Co., Ltd.)
We introduced confirmation and a method of analysis of SEI by "TOF - SIMS" and analyzed a trial manufacture cell in cooperation with Iwate University. It was detected than various chemical substances from spectrum data , and an electrolyte (each element of C, O, H), a material of every combination of Li salt (F, a P element) were detected as an ion (+, -).
(4) Study on a battery module specification
(5) Research and development of charge and discharge element technology
(6) Research and development of storage battery unit
