Apa itu
LFP gave up about a fifth of its energy density and in return removed nickel and cobalt from the bill entirely. Once pack engineering compensated for the weight, it took the majority of new cells worldwide.

Indicative range compiled from published technology studies and chemistry; verify against a manufacturer specification before use. Baris yang ditandai "trace" mengandung material dalam jumlah yang terlalu kecil untuk dinyatakan secara bermakna sebagai massa — kendala di sini adalah kemurnian atau jumlah pemasok, bukan tonase.
Alternatif-alternatifnya
Substitusi adalah kekuatan yang paling diremehkan dalam dunia material. Ketika sebuah logam menjadi mahal atau sulit secara politis, para insinyur merancang solusi alternatifnya — dan permintaan terhadap seluruh tambang bisa lenyap begitu saja.
NMC Lithium-Ion Battery
The high-energy chemistry — nickel, manganese and cobalt in the cathode — used where range matters most.
Sodium-Ion Battery
A cell that uses sodium — from ordinary salt — instead of lithium, at the cost of energy density.
Vanadium Redox Flow Battery
A battery that stores its energy in two tanks of dissolved vanadium, so power and capacity scale separately.
