Cell Energy Density

January 14, 2023 by Nigel
cell energy density roadmap

When we say cell energy density we need to consider if this is gravimetric (Wh/kg) or volumetric (Wh/litre). The energy content of the cell will be determined by the discharge rate, temperature and other parameters. Discharge rate capability of a new SAFT MP 176065 xtd battery. As you can see, at a C/8 discharge rate … Read more

Pack Gravimetric Energy Density

February 23, 2023February 27, 2022 by Nigel
benchmarking battery packs

Pack Gravimetric Energy Density has the units Wh/kg and is a key pack metric. The optimum metric is a high Wh/kg. Hence: The best you can achieve will be less than or equal to the cell Wh/kg that the pack is made from. Perhaps the simplest of the battery metrics as the capacity of the cell … Read more
