ELEKTRODE FÜR EINE WIEDERAUFLADBARE LITHIUM-BATTERIE, WIEDERAUFLADBARE LITHIUM-BATTERIE UND VERFAHREN ZUR HERSTELLUNG BESAGTER WIEDERAUFLADBARER LITHIUM-BATTERIE

摘要

An electrode for a lithium secondary battery including a sheet-like current collector and an active material layer carried on the current collector. The active material layer is capable of absorbing and desorbing lithium, and the active material layer includes a plurality of columnar particles having at least one bend. An angle ¸ 1 formed by a growth direction of the columnar particles from a bottom to a first bend of the columnar particles, and a direction normal to the current collector is preferably 10° or more and less than 90°. When ¸ n+1 is an angle formed by a growth direction of the columnar particles from an n-th bend counted from a bottom of the columnar particles to an (n+1)-th bend, and the direction normal to the current collector, and n is an integer of 1 or more, ¸ n+1 is preferably 0° or more and less than 90°.
