Power versus Energy Cells

Power versus Energy Cell Cost. Previouly we have looked at the fundamental differences between the power and energy cells, but why is there a Power versus Energy Cell Cost difference? Typically, energy cells cost ~80-100 $/kWh in 2024 and power cells ~150-300 $/kWh. Although, there are some exotic power cells that cost ~$600/kWh.
