Ex: you can buy carrots precut from the grocery store in "matchstick" form. You can buy pre-minced garlic. You can buy pre-soaked + cooked canned beans. There's no reason to work overly hard preparing meals.
Not everything is available pre-made in the grocery store. But the preparations you do can be batched up into larger sections. Cut the entire onion, or two, or three. Then tomorrow, you have pre-cut onions for other meals. Don't cook 1 cup of rice for today, cook 3 or 4 cups, so that you have rice for fried rice tomorrow.

I like the idea of prep-work being applied to writing. Batching additional work together can make you more efficient in cooking, so it makes sense that batching research together (for many different articles) would make you a more efficient writer, when it comes to writing many (say, 50 articles) at once.
