Lattice energy is the energy given off when oppositely charged ions in the gas phase form a solid. It measures the strength of a bond between ions so if it is more tightly compact, the bond is stronger and so lattice energy will be greater.
The molecules in gases due to their high energy naturally want to spread out and move around in their environment. When they are pushed together to form a solid, it will naturally take a lot of energy to keep them locked together, which is what lattice energy is.
