Zowel LFP (LiFePo4) als NMC behoren tot de lithium-ion (li-ion) familie. Toch zijn er grote verschillen tussen deze twee technologieën. Dit heeft vooral te maken met energiedichtheid, kosten, brandgevaar, degradatie en beschikbaarheid van grondstoffen.. Het meest belangrijke verschil om te weten is dat NMC thuisbatterijen kans hebben op brandgevaar.
Lithium-ion batteries (LIBs) are widely used in portable consumer electronics, clean energy storage, and electric vehicle applications.
