IANAE, but from my very brief topic search last month (~50 hours) the risks are competitive, that some other chemistry turns out to be "better" for a major application or that some other company does it better than you. There is always the possibility that someone figures out how to make cheap, safe, reliable, durable, high-current, temperature-tolerant and abuse-tolerant X-air (aluminum-air, lithium-air, or some other common metal or anion -air) batteries. The holy grail of max energy density, volumetric and gravimetric. There are many niches in storage, though, especially in stationary uses. Lifetime cost (10 to 50 years) will dominate for some, sticker (label) price for others.
