Morphology

nickel-cadmium + accumulator

The phrase denotes a battery made from nickel and cadmium; its meaning is directly derivable from the material-specifying modifier 'nickel-cadmium' plus 'accumulator' (a device that stores electricity). This material+device compositional pattern is common in technical vocabulary (e.g. 'lead-acid battery', 'lithium-ion battery'), so a learner who knows the constituents can infer the meaning.

Etymology

Nickel-cadmium accumulator is a name that describes what it is: it contains the metals nickel and cadmium, and accumulator is an old word for something that 'stores power'. So, the name means a rechargeable battery that holds energy using those metals.
