Quick tip: Check the alien bases on the island and in the Lost River biome. You'll often find ion cubes there.

I just grabbed a bunch from the Alien Thermal Plant. Bring a prawn suit with a drill arm to mine the big deposits.

You can find ion cubes in the Alien Arch Caches scattered around the map. Look out for green glowing objects in these structures!

Just explore the deep biomes and alien structures. Pretty much every alien base has ion cubes.
