A Study on Lithium Hydroxide Recovery Using Bipolar Membrane Electrodialysis
바이폴라 전기투석을 이용한 수산화리튬 회수에 관한 기초 연구
Yeonchul Cho, Kihun Kim, Jaewoo Ahn, Jaeheon Lee
조연철, 김기훈, 안재우, 이재헌
Korean J. Met. Mater. 2021;59(4):223-232.   Published online 2021 Mar 24
DOI: https://doi.org/10.3365/KJMM.2021.59.4.223

Bipolar electrodialysis was used in a process of desalting a lithium sulfate solution, converting it to lithium hydroxide and sulfuric acid, and concentrating and recovering them. The effects of the experimental variables such as applied voltage, the concentration of electrode solution, the concentration of raw material solution, volume ratio, and..... More

A Study on the Separation and Concentration of Li from Li-Containing Waste Solutions by Electrodialysis
리튬함유 폐액으로부터 전기투석에 의한 리튬의 분리·농축 연구
Jueun Lee, Hongil So, Yeonchul Cho, Inhwan Jang, Jaewoo Ahn, Jaeheon Lee
이주은, 소홍일, 조연철, 장인환, 안재우, 이재헌
Korean J. Met. Mater. 2019;57(10):656-662.   Published online 2019 Sep 6
DOI: https://doi.org/10.3365/KJMM.2019.57.10.656

Electrodialysis was used to develop a highly efficient process for concentrating and recovering Li from the Li-containing waste solution that is generated after recovering Co and Ni from a leach solution of waste cathode materials of Li ion batteries. The optimum conditions were investigated by comparing the concentration of Li..... More

Study on the Optimum Conditions for Synthesizing a Cathode Active Material Precursor in Li-Ion Batteries Using a Taylor Reactor
테일러 반응기를 이용한 최적의 리튬이차전지용 양극활물질 전구체 합성 조건 선정을 위한 연구
Deokhyun Han, Iljeong Park, Minjun Kim, Daeweon Kim, Hangchul Jung
한덕현, 박일정, 김민준, 김대원, 정항철
Korean J. Met. Mater. 2019;57(6):360-365.   Published online 2019 May 16
DOI: https://doi.org/10.3365/KJMM.2019.57.6.360

Li(Ni1-x-yCoxMny)O2 (NCM) materials, which are the cathode active material for lithium ion batteries, have been developed and widely used as an alternative to lithium cobalt oxide, because of the high cost of cobalt. To synthesize high quality NCM materials, it is important to control the process manufacturing of the NCM..... More

Recovery of Lithium as Li<sub>3</sub>PO<sub>4</sub> from Waste Water in a LIB Recycling Process
폐리튬이온전지 재활용 공정 폐액으로부터 리튬의 회수를 위한 인산리튬 침전 특성 연구
Young-Jun Song
Korean J. Met. Mater. 2018;56(10):755-762.   Published online 2018 Oct 5
DOI: https://doi.org/10.3365/KJMM.2018.56.10.755

This study was conducted to obtain engineering design data for a process to recover lithium in the form of Li3PO4 from the waste water of a lithium ion battery (LIB) recycling process. The influence of temperature, pH, and concentration on the solubility of Li3PO4 and the reaction rate in the..... More

Fabrication of Si/SiO<sub>x</sub> Anode Materials by a Solution Reaction-Based Method for Lithium Ion Batteries
Hyeon-Woo Yang, Jung-Ho Lee, Sang-Chul Jung, Seung-Taek Myung, Woo-Seung Kang, Sun-Jae Kim
Korean J. Met. Mater. 2016;54(10):780-786.   Published online 2016 Oct 5
DOI: https://doi.org/10.3365/KJMM.2016.54.10.780

Si/SiOx composite anodes were prepared using a facile solution reaction-based method. Their initial capacity was significantly improved to 1.3 times that of SiOx by incorporating 3 wt% silicon nanoparticles into the SiOx. The capacity retention of the Si/SiOx anodes after 50 charge-discharge cycles was significantly enhanced, to 99%, compared with..... More
