Title (EN) ALL-SOLID-STATE LITHIUM SECONDARY BATTERY CONTAINING LLZO SOLID ELECTROLYTE AND METHOD FOR PREPARING SAME
(FR) BATTERIE SECONDAIRE AU LITHIUM ENTIÈREMENT SOLIDE CONTENANT UN ÉLECTROLYTE SOLIDE LLZO ET SON PROCÉDÉ DE PRÉPARATION

Abstract:
(EN) The present invention provides an all-solid-state lithium secondary battery comprising: a cathode containing a cathode active material, a first LLZO, a first conductive polymer, a first lithium salt and a conducting material; an anode containing a lithium metal; and a complex solid electrolyte layer between the cathode and the anode and containing a second LLZO, a second conductive polymer and a second lithium salt, wherein the first and second LLZO is each independently an aluminum doped or undoped LLZO. The all-solid-state lithium secondary battery of the present invention can enhance the discharge capacity and the cyclic property of the cell as both the cathode and the complex solid electrolyte layer contain a conductive polymer, a lithium salt and an inorganic-based ceramic solid electrolyte. Also, the method for preparing an all-solid-state lithium secondary battery of the present invention can reduce production costs by preparing the all-solid-state lithium secondary battery in a non-sintering manner as both the cathode and the complex solid electrolyte layer contain a conductive polymer, a lithium salt and an inorganic-based ceramic solid electrolyte, and can further reduce the internal resistance of the battery by controlling interfacial reactions between an active material and an active material, between solid electrolyte particles, and between an electrolyte and an electrode.
(FR) La présente invention concerne une batterie secondaire au lithium entièrement solide comprenant : une cathode contenant un matériau actif, un premier LLZO, un premier polymère conducteur, un premier sel de lithium et un matériau conducteur; une anode contenant un métal lithium; et une couche d'électrolyte solide complexe entre la cathode et l'anode et contenant un second LLZO, un second polymère conducteur et un second sel de lithium, le premier et le second LLZO étant chacun indépendamment un LLZO dopé ou non dopé à l'aluminium. La batterie secondaire au lithium entièrement solide de la présente invention peut améliorer la capacité de décharge et la propriété cyclique de l'élément lorsque la cathode et la couche d'électrolyte solide complexe contiennent un polymère conducteur, un sel de lithium et un électrolyte solide céramique à base inorganique. Le procédé de préparation d'une batterie secondaire au lithium entièrement solide de la présente invention peut réduire les coûts de production par préparation d'une batterie secondaire au lithium entièrement solide dans un mode sans frittage lorsque la cathode et la couche d'électrolyte solide complexe contiennent un polymère conducteur, un sel de lithium et un électrolyte solide céramique à base inorganique, et peut réduire également la résistance interne de la batterie par commande de réactions à l'interface entre un matériau actif et un matériau actif, entre des particules d'électrolyte solide, et entre un électrolyte et une électrode.
(KO) 본발명은 양극활물질, 제 1 LLZO, 제 1전도성 고분자, 제 1리튬염 및 도전재를 포함하는 양극;리튬 금속을 포함하는 음극; 및 양극과 음극사이에, 제 2 LLZO, 제 2 전도성 고분자 및 제 2 리튬염을 포함하는 복합고체전해질층;을 포함하고, 제 1및 제 2 LLZO는 각각 독립적으로 알루미늄이 도핑 또는 비도핑된 LLZO인 전고체 리튬이차전지가 제공된다. 본 발명의 전고체리튬이차전지는 양극과 복합고체전해질층에 동시에 전도성 고분자, 리튬염 및 무기계 세라믹 고체전해질을 포함하여 전지의 방전용량 및 싸이클 특성이 향상될 수 있다. 또한, 본 발명의 전고체 리튬이차전지의 제조방법은 양극과 복합고체전해질층에 동시에 전도성 고분자, 리튬염 및 무기계 세라믹 고체전해질을 포함시켜 비소결 방식으로 전고체 리륨이차전지를 제조함으로써 제조비용을 감소시키고, 활물질 /활물질간,고체전해질 입자 간, 전해질 /전극 간의 계면반응을 제어하여 전지의 내부저항을 보다 감소시킬 수 있다.
