Isolation Resistance of a Pack
physical distortion or damage to the pack; foreign bodies introduced to the pack, eg tools left in the pack during service; It is really important to understand that 500Ω/V is a legislative requirement for the vehicle. Which means it applies to the whole HV system not just the battery – a common misunderstanding. Several things follow from this:

Prismatic Cells
Pressure on Cell Surface. The cell electrode pressure is required to keep the cell operating at it''s peak performance over it''s lifetime. As the cell is charged lithium ions move into the graphite anode and the cell will increase in thickness. Silicon in the anode will increase this swelling significantly.
What is Battery Pack?
What is Battery Pack? A battery pack is a set of any number of (preferably) identical batteries or individual battery cells. They may be configured in a series, parallel, or a mixture of both to deliver the desired voltage, capacity, or power density.
What is the Energy Density of a Lithium-Ion Battery?
A battery with high energy density has a longer battery run time in relation to the battery size. Alternately, a battery with high energy density can deliver the same amount of energy, but in a smaller footprint compared to a battery with lower energy density.
Battery Comparison of Energy Density
Energy density: 272-296 Wh/kg. Tesla''s 4680-type battery cell weight was 355 g. The estimated total capacity is 26.136 Ah, while total energy is estimated at 96-99 Wh (assuming at 3.7-3.8 V).

See Inside Of The Tesla Model 3''s LFP Prismatic Battery Pack
Tesla accustomed us to using lithium-ion cells in cylindrical form factor, starting with 1865 (18650) in Model S/X, 2170 in Model 3/Y and soon 4680, but there is one exception - prismatic LFP cells.
Tesla LFP Model 3
The Tesla LFP Model 3 is quite a landmark battery pack for Tesla. Up until now everything has revolved around chasing the energy density of cylindrical cells from 18650 to 21700. The 4680 cylindrical is a move to a larger and lower cost cell. This move to Lithium Iron Phosphate (LFP) is perhaps more significant and triggered by the success of ...
Battery Parameters
Energy Density: The energy density of a battery, which is sometimes represented by the letter "U," is a measurement of how much energy it can hold relative to its volume or mass. Gravimetric energy density (Wh/kg), which measures energy stored per unit of mass, and volumetric energy density (Wh/L), which measures energy stored per unit of ...
