Nov 15 (Reuters) – The individual cells in most
rechargeable EV batteries today have the same basic components:
Electrodes, electrolyte and separator. The positive electrode is
called the cathode; the negative electrode is the anode.
The cathode is the single most expensive element, accounting
for up to a third of the cost of a battery cell. Most lithium
ion batteries today use one of two types of cathodes: Nickel
cobalt manganese (NCM) or lithium iron phosphate (LFP).
When the battery is being used and its stored energy is
being discharged tiny particles (called ions) inside the
battery travel from the anode to the cathode, through a chemical
solution called the electrolyte, creating an electrical current.
When the battery is being recharged, those particles then flow
back from cathode to anode.
Because lithium is stored in both cathode…
