MICROMACHINED ELECTROLYTE SHEET COMPRISING LITHIUM METAL PHOSPHATES
PROBLEM TO BE SOLVED: To provide a mechanically strong, thin, fine ceramic lithium ion electrolyte membranes having high-quality edges with no defect.SOLUTION: A method for forming a sintered electrolyte membrane comprises: (i) a tape casting step including the steps of casting a tape, drying the tape, releasing the tape, and cutting the tape; (ii) a step of sintering the cut tape at a temperature of 800 to 900°C; and (iii) a step of micromachining the sintered tape by a femtosecond-based laser operating at a wavelength of 1560 nm, a pulse energy of 10 μJ, and a repetition rate of 1 MHz with a pulse duration of less than 700 fs.SELECTED DRAWING: Figure 1A
【課題】高品質で欠陥のないエッジを有し、機械的に強く、薄い、微粒セラミックリチウムイオン電解質膜の提供。【解決手段】（ｉ）テープをキャストする工程と、前記テープを乾燥する工程と、前記テープを解く工程と、前記テープを切断する工程と、を含むテープキャスティング工程、（ｉｉ）切断された前記テープを８００〜９００℃の温度で焼結する工程、および、（ｉｉｉ）焼結された前記テープを、１５６０ｎｍの波長、１０μＪのパルスエネルギー、１ＭＨｚの繰り返し速度、および、７００ｆｓ未満のパルス期間で操作されるフェムト秒レーザーを使って、微細加工する工程、を含む、焼結電解質膜を形成する方法。【選択図】図１Ａ
