Morphology

element + 115

The phrase literally combines 'element' with the number 115, so a B1 learner who knows the words would understand it denotes the chemical element with atomic number 115. However, the specific fictional/pop-culture sense of a powerful or exotic energy source (distinct from the real element moscovium) is a culturally specific extension not predictable from the constituents alone, so full comprehension requires extra world knowledge.

Etymology

Element 115 in stories and games comes from people borrowing the real-sounding number and turning it into a strange fuel. One popular story says writers used the number to name a 'mysterious power' that can run alien machines, so element 115 now often means a fictional, powerful substance.
