Abstract
The present invention provides a composition for forming an electrode active material layer for lithium ion secondary batteries, the composition comprising an electrode active material and a carbon nanotube, wherein the content of the carbon nanotube is 0.01 to 1.4 mass % and the content of electrode constituent materials other than the electrode active material and the carbon nanotube is 0 to 10.0 mass %, based on the total amount of the composition taken as 100 mass %. This composition for forming an electrode active material layer for lithium ion secondary batteries is capable of producing a battery with extended life. After discharging the battery from a state of charge (SOC) of 100% to an SOC of 90% at 25° C. and 2.5 C, the discharging is paused for 10 minutes and an increase in voltage at pause is measured. The internal resistance is calculated according to the following formula (2):
