Novel estimation method of operating life in lithium-ion pouch cells

Autor: Ilbok Lee, Keebum Hwang, Nayeong Kim, Songhun Yoon, Hyosung Kim, Joongho Bae, Jaekwang Kim

Publikováno v: Journal of Industrial and Engineering Chemistry. 67:266-275

Herein, a novel operating life (OL) test method was evaluated with 200 mAh pouch-type lithium-ion batteries. By combining the calendar life (CL) test with intermediate pulse power cycling, more realistic life prediction was possible, which encompasse

Two-dimensional nanosheets of tungsten vanadate (WV 2 O 7 ) obtained by assembling nanorods on graphene as a supercapacitor electrode

Autor: Gyoung Hwa Jeong, Jaewoong Lim, Ilbok Lee, Songhun Yoon, Sang-Wook Kim

Publikováno v: Journal of Alloys and Compounds. 758:99-107

By cumulative assembly of tungsten vanadate (WV2O7) nanorods, novel two-dimensional (2D) nanosheets of interwoven tungsten vanadate were hydrothermally formed on graphene. When as-prepared material was applied into a supercapacitor electrode using H2
