Precycling of lithium (Li) metal on a nickel substrate at a low-temperature (-20 degreesC) in propylene carbonate (PC) mixed with dimethyl carbonate (DMC) and Li hexafluorophosphate (LiPF6) (LiPF6-PC/DMC) enhanced Li cyclcability in the subsequent cycles at a room temperature (25 degreesC). In LiPF6-PC/DMC, not only the low-temperature precycling in the initial 10 cycles was effective in the improvement of Li cycle life but also the first low-temperature Li deposition followed by room temperature cycling enhanced the: Li cycle life. Such a precycling effect was observed with various current densities at the initial Li deposition and the subsequent cycling. When the current density of the cycling was high, improved cycling efficiency was observed and the efficiency of the Li electrode undergoing the precycling was dose to that at a constant temperature of -20 degreesC.
