Abstract
Description
‐負極LiTi2(PO4)3:C.Wessellsら、J.Electrochem.Soc.,Vol.158(3)、p.A352(2011年)(非特許文献1)
‐正極LiMn2O4:W.Liuら、J.Electrochem.Soc.,Vol.143(3),p.879(1996年)(非特許文献2)、但し、7.5mol%の硝酸マンガン(II)は硝酸クロム(III)に置き換えている。
負極:300rpmで3時間、遊星型ボールミルにおいて(20mm直径めのうボール)、LiTi2(PO4)3とカーボンブラック(Super P)を1:1の割合で粉砕することにより複合体を形成する。次に、8%PVDF(Kynar)及び4%グラファイト(Timrex MX15)と共にめのう乳鉢で粉砕を行い、次いでNMPを添加し、PVDFが溶解して均質な分散物が得られるまで粉砕を継続する(固形分約50%)。
上記のように測定した約2500Paのヤング率及び約300Paのずり弾性率を示し、厚さが0.4mmの独立気泡アクリル発泡体の中央層を備えた3M(商標)から販売されているVHB(商標)接着粘弾性エラストマーテープのストリップを切断して所望のガスケット寸法にする(例えば、外寸50mm×25mm及び内寸40mm×15mmの矩形フレーム)。
本発明に従って得られた電池を2枚のPETフィルムの間に挟む。各フィルムの一端を、所望の曲率半径の2倍に相当する直径のシリンダ上に固定する。他端は、電池を屈曲させるため、すなわち円筒に押し付けるために十分に重い500gの平衡錘に固定する。
