Performance of SONY 18650-HC Lithium-Ion Cells for Various Cycling Rates

Abstract

Five different life tests of SONY 18650-HC lithium-ion cells have been run for up to 10 years. These tests evaluate the 18650-HC lithium-ion cells under conditions ranging from rapid cycling at 32 cycles per day, to slow cycling at 90 cycles per year, to stand tests that involve no cycling at all. These tests examine the self-discharge of the cells, the divergence between cells in batteries, and their degradation rates as a function of the cycling rate and calendar life for cells manufactured at several points in time.
