Potassium perylene-tetracarboxylate with two-electron redox behaviors as a highly stable organic anode for K-ion batteries
TL;DR: Potassium perylene-3,4,9,10-tetracarboxylate was exploited as a new organic anode for potassium-ion batteries, exhibiting two-electron redox behavior and a theoretical capacity of 93 mA h g-1.
Journal ArticleDOI
Using an organic acid as a universal anode for highly efficient Li-ion, Na-ion and K-ion batteries
TL;DR: Terephthalic acid (H2TP) is the first example of organic anodes exhibiting the universal Li-ion, Na-ion and K-ion storage capabilities as mentioned in this paper, which indicates that organic electrode materials should own the universal metal ion storage capability for their large void room of organic solid/crystal state.

Ruihan Zhang,Yadong Zheng,Zeyi Yao,Panawan Vanaphuti,Xiaotu Ma,Sungyool Bong,Mengyuan Chen,Yangtao Liu,Feng Cheng,Zhenzhen Yang,Yan Wang +10 more
TL;DR: Many recycling processes have been developed for spent Li-ion batteries (LIBs) such as pyrometallurgy, hydrometalurgy, and direct recycling as discussed by the authors.
Journal ArticleDOI
Understanding fundamental effects of Cu impurity in different forms for recovered LiNi0.6Co0.2Mn0.2O2 cathode materials
Ruihan Zhang,Zifei Meng,Xiaotu Ma,Mengyuan Chen,Bin Chen,Yadong Zheng,Zeyi Yao,Panawan Vanaphuti,Sungyool Bong,Zhenzhen Yang,Yan Wang +10 more
TL;DR: In this paper, the role of impurity in different forms on the recovered LiNi0.6Co0.2O2 (NCM622) battery was investigated and shown that Cu ion impurity could play a positive role due to partially substitution of the Ni2+ sites to lower the cation mixing degree.

Xiaotu Ma,Panawan Vanaphuti,Jinzhao Fu,Jiahui Hou,Yangtao Liu,Ruihan Zhang,Sungyool Bong,Zeyi Yao,Zhenzhen Yang,Yan Wang +9 more
TL;DR: In this paper, a universal etching approach was firstly developed to synthesize single-crystal cathode materials, which achieved a significant improvement in rate performance, especially at high rates (28.6% at 5C and 129% at 10C) and comparable cycle performance compared to polycrystalline NMC622.
