Abstract: Methods and systems are disclosed herein for accurately calculating battery consumption in a wireless field device. The total current consumed by a radio board associated with a wireless field device can be determined based on the sum of the current consumed as a result of particular events occurring at the radio board. The current consumed by a sensor board of the wireless field device can then be averated with respect to particular type of sensor. The current consumed by the radio board and the current consumed by the sensor board in the wireless field device can be combined to calculate a predictive value indicative of a remaining life of a battery associated with the wireless field device.

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): Internal resistance = (Increase in voltage at pause (V)/Current during discharge (A)) x Facing area between positive electrode and negative electrode (cm2) whereby uneven reaction distribution in the battery, which causes a rapid decrease of the capacity (secondary deterioration), can be assessed.
