| 1 | Trace Nb-doped Na_(0.7)Ni_(0.3)Co_(0.1)Mn_(0.6)O_(2) with suppressed voltage decay and enhanced low temperature performance显示文摘The P2-type manganese-based Na_(0.7)MnO_(2) cathode materials attract great interest due to their high theoretical capacity.However,these materials suffer from rapid capacity fading,poor rate performance and severe voltage decay resulting from phase transition and sluggish reaction kinetics.In this work we report a novel Nb-doped Na_(0.7)[Ni_(0.3)Co_(0.1)Mn_(0.6)]_(1-x)Nb_(x)O_(2) with significantly suppre ssed voltage decay and enhanced cycling stability.The strong Nb-O bond can efficiently stabilize the TMO fra mework,and the as prepared material demonstrates much lower discharge midpoint voltage decay(0.132 V) than that of pristine one(0.319 V) after 200 cycles.Consequently,a remarkably improved cycling perfo rmance with a capacity retention of 87.9% after 200 cycle at 0.5 C is achieved,showing a 2.4 fold improvement as compared to the control sample Na_(0.7)Ni_(0.3)Co_(0.1)Mn_(0.6)O_(2)(~37% rotation).Even at 2 C,a capacity retention of 68.4% is retained after 500 cycles.Remarkably,the as prepared material can be applied at low temperature of-20℃,showing a capacity retention of 81% as compared to that at room temperature. | Ruyun Yue Fang Xia Ruijuan Qi Da Tie Shanshan Shi Zhiping Li Yufeng Zhao Jiujun Zhang | 2021 | Chinese Chemical Letters2021，32，2： | 2 |

| 4 | Realizing simultaneously enhanced energy and power density fullcell construction using mixed hard carbon/Li_(4)Ti_(5)O_(12) electrode显示文摘Practical applications of lithium-ion batteries(LIBs)with both high energy and power density are urgently demanded,which require suitable charge/discharge platform,fast charge-transfer kinetics,as well as optimal solid electrolyte interphase(SEI)layer of electrode materials.In this work,a high-performance lithium-ion battery(LIB)full cell was assembled by using commercial LiNi_(0.33)Co_(0.33)Mn_(0.33)O_(2)(NCM111)as the positive electrode and mixed Li_(4)Ti_(5)O_(12)(LTO)/hard carbon(HC)as the negative electrode.It reveals that the component ratio between LTO and HC plays a critical role in manipulating the electric conductivity and the electro-reaction platform.The electrochemical test results show that when the content of HC is 10 wt%,the as-constructed full cell demonstrates the best electrochemical,with a maximum energy density of 149.2 Wh·kg^(-1) and a maximum power density of2195 W·kg^(-1) at 10 A·g^(-1)(30 C).This outperforms all the assembled systems within our work range and the state-ofthe-art literatures.The NCM//Li_(4)Ti_(5)O_(12)+10 wt%HC battery system also exhibits a good capacity retention after1000 cycles at the current density of 1 A·g^(-1).This work provides a new approach to enhance the full-cell performance by mixing electrode materials with different charge potentials and reaction kinetics. | Shi-Fei Huang Yao Lv Da Tie Yang Yu Yu-Feng Zhao | 2021 | Rare Metals2021，40，1： | 1 |
