抄録/ポイント： レート性能と低温で,三元系カソード材料,LiNi_1/3Co_1/3Mn_1/3O_2の貧弱な性能をその更なる応用を制限し,電子市場。以前の研究のいくつかは,カソード材料の表面改質は,そのサイクル安定性を高めることができることを報告する。本研究では,(42.5 x)Li_2O:57.5B_2O_3:xLi_2SO_4修飾LiNi_1/3Co_1/3Mn_1/3O_2カソード材料を溶液法とそれに続く500°Cでの熱処理によって調製した。リチウム高速イオン伝導体(42.5 x)Li_2O:57.5B_2O_3:xLi_2SO_4はLiNi_1/3Co_1/3Mn_1/3O_2のための安定な表面保護を提供する。結果は(42.5 x)Li_2O:57.5B_2O_3:xLi_2SO_4修飾LiNi_1/3Co_1/3Mn_1/3O_2は高速度と低温度で強化された電気化学的性能を示すことが分かった。(42.5 x)Li_2O:57.5B_2O_3:xLi_2SO_4(x=10)修飾LiNi_1/3Co_1/3Mn_1/3O_2試料は 20°Cでの1Cの速度で48.6%から70.0%にLiNi_1/3Co_1/3Mn_1/3O_2の放電容量保持を増加33.4%から85.3%に高分解能透過型電子顕微鏡と走査電子顕微鏡はLiNi_1/3Co_1/3Mn_1/3O_2の元の構造上の薄いLi_2O B_2O_3 Li_2SO_4被覆層(約10nm)の存在を確認した。サイクリックボルタンメトリーと電気化学インピーダンス分光法試験結果は,LBOS被覆の存在はリチウムイオン移動に対する界面抵抗を減少させることを示した。Copyright 2017 Elsevier B.V., Amsterdam.
