However energy density CCC-battery-cost_-Element-Energy-report_March2012_Finalbishas emerged as the most important metric in battery design, leading to lithium family chemistries becoming the dominant chemistry for pure and Plug inCCC-battery-cost_-Element-Energy-report_March2012_Finalbis

The whole battery system including cells, structural support, thermal management and electronic balance. IS called the battery pack. The cost of a battery pack for a pure EV CCC-battery-cost_-Element-Energy-report_March2012_Finalbis IS approximately $800/kWh, i.e. double the cost of the cells alone.Automotive cells represent only a marginal share (<5%) of the rechargeable lithiumCCC-battery-cost_-Element-Energy-report_March2012_Finalbis
