Promises and challenges of next-generation "beyond Li-ion" batteries for electric vehicles and grid decarbonization
Yaosen Tian,Yaosen Tian,Guobo Zeng,Guobo Zeng,Ann Rutt,Tan Shi,Haegyeom Kim,Jingyang Wang,Jingyang Wang,Julius Koettgen,Yingzhi Sun,Yingzhi Sun,Bin Ouyang,Bin Ouyang,Tina Chen,Tina Chen,Zhengyan Lun,Zhengyan Lun,Ziqin Rong,Kristin A. Persson,Kristin A. Persson,Gerbrand Ceder,Gerbrand Ceder +22 more
TL;DR: In this paper, the authors discuss the recent achievements, challenges, and opportunities of four important "beyond Li-ion" technologies: Na-ion batteries, K-ion, all-solid-state batteries, and multivalent batteries.
Realizing continuous cation order-to-disorder tuning in a class of high-energy spinel-type Li-ion cathodes

McCloskey,Mahalingam Balasubramanian,Raphaële J. Clément,Wanli Yang,Gerbrand Ceder,Gerbrand Ceder +29 more
TL;DR: In this article, the authors identify cation to anion ratio in synthesis as a key parameter for tuning the structure continuously from a well-ordered spinel, through a partially ordered spinel to rocksalt, and find that varying degree of cation disorder modifies the voltage profile, rate capability, and charge compensation mechanism in a rational and predictable way.

Increasing Capacity in Disordered Rocksalt Cathodes by Mg Doping
Peichen Zhong,Peichen Zhong,Zijian Cai,Zijian Cai,Ya-Qian Zhang,Ya-Qian Zhang,Raynald Giovine,Bin Ouyang,Bin Ouyang,Guobo Zeng,Guobo Zeng,Yu Chen,Yu Chen,Raphaële J. Clément,Zhengyan Lun,Zhengyan Lun,Gerbrand Ceder,Gerbrand Ceder +17 more
TL;DR: In this paper, Zhong et al. demonstrate that the performance of Li-excess cation-disordered rocksalt cathodes can be improved by Mg substitution, which reduces the amount of Li in the compound that is strongly bound to F and thereby increases the capacity.
Journal ArticleDOI

Solid-State Calcium-Ion Di ff usion in Ca 1.5 Ba 0.5 Si 5 O 3 N 6
Yu Chen,Christopher J. Bartel,Maxim Avdeev,Ya-qian Zhang,Jue Liu,Peichen Zhong,Guobo Zeng,Zijian Cai,Haegyeom Kim,Huiwen Ji,Gerbrand Ceder +10 more
TL;DR: In this paper , the authors investigated the Ca migration mechanism in solid-state materials and provided insights into the future design of novel cation conduction schemes that utilize the interactions between mobile ions to enable fast multivalent-ion conduction in solid state materials.
