How Lithium-ion Batteries Work
Energy density is measured in watt-hours per kilogram (Wh/kg) and is the amount of energy the battery can store with respect to its mass. Power density is measured in watts per kilogram (W/kg) and is the amount of power that can be generated by the battery with respect to its mass. To draw a clearer picture, think of draining a pool.

Battery Cell Balancing: What to Balance and How
cells chemical state of charge will be (Qmax-Q1)/Qmax = 95.4%, but third cell will be 91%. So we can say cell 3 is imbalanced by 4.4%. This in turn will result in a different open circuit voltage for cell 3 compared to cells 1 and 2, because the open circuit voltage (OCV) is in direct correlation with chemical state of charge.
Power versus Energy Cells
In simple terms the energy cell has thicker layers of active material, thinner current collectors and less of them. This means the energy cell will have a higher electrical internal resistance meaning it will generate more heat based on I 2 R heating.. The energy cell will have poorer thermal conductivity in-plane and through-plane. Thus, it will need a higher …
