Morphology
nickel-iron + accumulator
The compound names the constituent metals (nickel + iron) plus the device type 'accumulator' (battery), so a learner who knows those words can infer it is a battery made from nickel and iron. Technical electrochemical details in the full definition are specialized, but the core meaning is directly compositional and therefore predictable to a B1 learner.
Etymology
Nickel-iron accumulator is a literal name: it points to the two metals nickel and iron inside and uses accumulator, an old word for a device that 'stores' electricity. Imagine the two metals as strong buckets that hold electricity and can be filled again and again, which is why the term today means a long-lasting rechargeable battery.
