REsPECT_e-ASIA
Closed-loop Recycle Process of Spent Primary and Secondary Batteries and the Reutilization for the Environmental Applications & Circular Economy (REsPECT) aims to cooperatively closed-loop recycle Mn, Zn and C from spent alkaline and Zn-C batteries and Li, Mn, Co, Ni, C from spent Li-ion battery collected in Thailand, Japan and Indonesia to be reutilized for the environmental applications as follows: (i) Zn and Ni/Co/MnOx/C for rechargeable Zn-ion battery, (ii) Li/Ni/Mn/AlOx for high-performance LIB with fast-charging capability (iii) NaFeMnOx for Na-ion battery and (iv) Ni/Co/Mn/ZnOx composites as photocatalysts for the waste water treatment and hydrogen production.

Project Background
The Thailand team (12 experts in Materials Science, Chemistry, and Chemical Engineering) has worked on alkaline and Zn-C primary-battery recycling since 2018. Their hydrometallurgical process achieves 50-70% recovery efficiency at the pilot scale. Current efforts focus on enhancing metal recovery, producing high-purity Zn films, MnOâ‚‚, and MnOâ‚‚/C nanocomposites for use in Zn-ion batteries (ZIB), Li-ion batteries (LIB), and photocatalysis.
The Japanese team (led by Watanabe) specializes in environmentally friendly lithium recovery. Their soft solution and ammonothermal methods have developed LiCoOâ‚‚ for LIB and visible-light photocatalysts. Okazaki’s expertise in lithium separation supports hydrothermal recovery, while Murakushi focuses on solid-state material analysis.
The Indonesian team (five researchers) has worked on LIB and Na-ion batteries (NIB) since 2013, developing high-nickel-free LNMA and LTO cathodes with biomass-based carbon coatings. They also propose LNMA synthesis from natural and recycled materials for fast-charging LIB and Sodium Ferro Mangan Oxide (NFMO) cathodes for NIB.
