Title
(EN) ELECTROCHEMICAL DEVICE HAVING HIGH POWER PROPERTIES
(FR) DISPOSITIF ÉLECTROCHIMIQUE PRÉSENTANT DES PROPRIÉTÉS DE PUISSANCE ÉLEVÉE
(KO) 고출력 특성을 가진 전기화학소자
Abstract
(EN) The present invention provides an electrochemical device in which there is a combined use of an electrode in which an oxide film is formed by using an atomic layer deposition (ALD), and a non-aqueous electrolyte including a dimethoxyethane-based compound, and preferably provides a lithium secondary battery. The present invention exhibits a cycle life that is equal to the conventional non-aqueous electrolyte battery, and in particular, exhibits significantly improved high power (C-rate) properties.
(FR) La présente invention se rapporte à un dispositif électrochimique pour lequel il y a un usage combiné d'une électrode dans laquelle est formé un film d'oxyde à l'aide d'un dépôt de couche atomique (ALD pour Atomic Layer Deposition) et d'un électrolyte non aqueux comprenant un composé à base de diméthoxyéthane et, de préférence, se rapporte à une batterie rechargeable au lithium. La présente invention présente un cycle de vie qui est égal à la batterie à électrolyte non aqueux classique et, en particulier, présente des propriétés de puissance élevée significativement améliorées (régime C).
(KO) 본 발명은 원자층 증착법(atomic layer deposition: ALD)을 이용하여 산화물 피막이 형성된 전극; 및 디메톡시에탄계 화합물을 포함하는 비수계 전해액을 병용(竝用)하는 전기화학소자, 바람직하게는 리튬 이차 전지를 제공한다. 본 발명에서는 기존 비수 전해액 전지와 대등한 사이클 수명 특성을 나타내면서, 특히 고출력(C-rate) 특성을 유의적으로 향상시킬 수 있다.
