Abstract

The satellite REIMEI was launched in August 2005, this is one of the first satellites to use Li-ion batteries. REIMEI is a small scientific satellite designed for carrying out aurora observations using three different cameras. The main scientific mission of the satellite ended in 2013. More than 14 years have passed, and the batteries have experienced over 78,100 charge/discharge cycles. REIMEI remains in operation with a new mission dedicated to analyzing its Li-ion battery. In this work, we present a durability analysis for the REIMEI battery based on telemetry data.

Abstract

Commercially available 18650 Li-ion cells were exposed to charge-discharge cycling at 0°C using two different charging protocols: constant current-constant voltage (CC-CV) and constant current (CC). The effect of the charge process protocol on the Li-ion cell performance is shown and analyzed. After exposing the cells to low temperature charging, a high voltage plateau appeared at the beginning of the discharge. This high voltage plateau is related to the occurrence of lithium plating during the charging process. Interestingly, the intensity of the observed high voltage plateau decreased with cycling. In addition, the Li-ion cells that were charged using a CC protocol exhibited a larger capacity fade in comparison to those that were charged using a CC-CV protocol. Furthermore, electrochemical impedance spectroscopy (EIS) measurements were carried out during cycling. It was shown that the internal impedance of the cells increased with charge-discharge cycling, indicating the formation of an interphase layer during low temperature cycling.

Abstract

Commercially available 18650 LiFePO4-Graphite Li-ion cells were exposed to charge-discharge cycling at 0°C following two different charge methods: constant current-constant voltage (CC-CV) and constant current (CC), and two different discharge rates: 1 C and 0.2 C. The effect of the charge method and discharge rate on the cell performance was analyzed. The cell exposed to CC charge and 1 C discharge-rate showed a high voltage plateau at the beginning of the discharge voltage, while a high voltage plateau was not observed in the discharge profiles of the cells exposed to a discharge rate of 0.2 C.
