Lo que es
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. Las filas marcadas como «traza» contienen el material en cantidades demasiado pequeñas para expresarse de forma útil como masa; la restricción allí es la pureza o el número de proveedores, no el tonelaje.
Las alternativas
La sustitución es la fuerza más subestimada en materiales. Cuando un metal se encarece o resulta políticamente problemático, los ingenieros diseñan soluciones alternativas — y la demanda de una mina entera puede desvanecerse.
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.
