There's a good reason for this.
The funding agencies from which scientists seek money fund "research," in the broad sense, not "development." What you're hinting at is the fundamental difference between the two.
Agencies like NSF tend to assume that if one of the projects they fund has practical applications, then "partners" (i.e., the private sector) will handle the development. Indeed, this is how Goodenough's original battery design came to market. Sony licensed the patent from Oxford University in the 1980s and started mass-producing lithium-ion batteries, paying Oxford a royalty on every battery manufactured.
