Totally different type of cells. LCO and NMC batteries which this would theoretically replace are energy cells with a specific energy of around 200Wh/kg. These are used when total energy matters, but you don't need high charge/discharge rates, such as with a laptop or cellphone.
LFP like you are talking about are considered power cells (along with Manganese Spinel). The specific energy is about half of an energy cell at around 90-120 Wh/kg. These are that cells you use when you want the stored energy quickly, such as with an electric car or power tools.
