| 2 | Tailoring the LiNbO_(3)coating of Ni-rich cathode materials for stable and high-performance all-solid-state batteries显示文摘The research and development of advanced nanocoatings for high-capacity cathode materials is currently a hot topic in the field of solid-state batteries(SSBs).Protective surface coatings prevent direct contact between the cathode material and solid electrolyte,thereby inhibiting detrimental interfacial decomposition reactions.This is particularly important when using lithium thiophosphate superionic solid electrolytes,as these materials exhibit a narrow electrochemical stability window,and therefore,are prone to degradation during battery operation.Herein we show that the cycling performance of LiNbO_(3)-coated Ni-rich LiNi_(x)Co_(y)Mn_(z)O_(2)cathode materials is strongly dependent on the sample history and(coating)synthesis conditions.We demonstrate that post-treatment in a pure oxygen atmosphere at 350℃results in the formation of a surface layer with a unique microstructure,consisting of LiNbO_(3)nanoparticles distributed in a carbonate matrix.If tested at 45℃and C/5 rate in pellet-stack SSB full cells with Li_(4)Ti_(5)O_(12)and Li_(6)PS_(5)Cl as anode material and solid electrolyte,respectively,around 80%of the initial specific discharge capacity is retained after 200 cycles(~160 mAh·g^(−1),~1.7 mAh·cm^(−2)).Our results highlight the importance of tailoring the coating chemistry to the electrode material(s)for practical SSB applications. | Seyedhosein Payandeh Florian Strauss Andrey Mazilkin Aleksandr Kondrakov Torsten Brezesinski | 2022 | Nano Research Energy2022，1，3： | 2 |

| 5 | P2-type layered high-entropy oxides as sodium-ion cathode materials显示文摘P2-type layered oxides with the general Na-deficient composition Na_(x)TMO_(2)(x<1,TM:transition metal)are a promising class of cathode materials for sodium-ion batteries.The open Na+transport pathways present in the structure lead to low diffusion barriers and enable high charge/discharge rates.However,a phase transition from P2 to O2 structure occurring above 4.2 V and metal dissolution at low potentials upon discharge results in rapid capacity degradation.In this work,we demonstrate the positive effect of configurational entropy on the stability of the crystal structure during battery operation.Three different compositions of layered P2-type oxides were synthesized by solid-state chemistry,Na_(0.67)(Mn_(0.55)Ni_(0.21)Co_(0.24))O_(2),Na_(0.67)(Mn_(0.45)Ni_(0.18)Co_(0.24)Ti_(0.1)Mg_(0.03))O_(2) and Na_(0.67)(Mn_(0.45)Ni_(0.18)Co_(0.18)Ti_(0.1)Mg_(0.03)Al_(0.04)Fe_(0.02))O_(2) with low,medium and high configurational entropy,respectively.The high-entropy cathode material shows lower structural transformation and Mn dissolution upon cycling in a wide voltage range from 1.5 to 4.6 V.Advanced operando techniques and post-mortem analysis were used to probe the underlying reaction mechanism thoroughly.Overall,the high-entropy strategy is a promising route for improving the electrochemical performance of P2 layered oxide cathodes for advanced sodium-ion battery applications. | Junbo Wang Sören L Dreyer Kai Wang Ziming Ding Thomas Diemant Guruprakash Karkera Yanjiao Ma Abhishek Sarkar Bei Zhou Mikhail V Gorbunov Ahmad Omar Daria Mikhailova Volker Presser Maximilian Fichtner Horst Hahn Torsten Brezesinski Ben Breitung Qingsong Wang | 2022 | Materials Futures2022，1，3： | 0 |
| 6 | The interplay between (electro)chemical and (chemo)mechanical effects in the cycling performance of thiophosphate-based solid-state batteries显示文摘Solid-state batteries(SSBs)are a promising next step in electrochemical energy storage but are plagued by a number of problems.In this study,we demonstrate the recurring issue of mechanical degradation because of volume changes in layered Ni-rich oxide cathode materials in thiophosphate-based SSBs.Specifically,we explore superionic solid electrolytes(SEs)of different crystallinity,namely glassy 1.5Li_(2)S-0.5P_(2)S_(5)-LiI and argyrodite Li_(6)PS_(5)Cl,with emphasis on how they affect the cyclability of slurry-cast cathodes with NCM622(60%Ni)or NCM851005(85%Ni).The application of a combination of ex situ and in situ analytical techniques helped to reveal the benefits of using a SE with a low Young’s modulus.Through a synergistic interplay of(electro)chemical and(chemo)mechanical effects,the glassy SE employed in this work was able to achieve robust and stable interfaces,enabling intimate contact with the cathode material while at the same time mitigating volume changes.Our results emphasize the importance of considering chemical,electrochemical,and mechanical properties to realize long-term cycling performance in high-loading SSBs. | Jun Hao Teo Florian Strauss Felix Walther Yuan Ma Seyedhosein Payandeh Torsten Scherer Matteo Bianchini Jürgen Janek Torsten Brezesinski | 2022 | Materials Futures2022，1，1： | 0 |
