20 years? You really believe that? Everyone is working increasing battery density, everyone is working solid state batteries. Toyota will debut solid state batteries next summer in the transports they are building for the summer games in Japan. Competition does not stand still, especially as I stated in another post when profit is the motivator.
Toyota has been trying to make solid state batteries work for vehicles, but they aren't doing any EVs unless they are compelled to: their plans are for "electrified" cars -- that is hybrid, hydrogen and, maybe, EV, where regulators force them to. They have made it abundantly clear that they are not interested in EVs, presumably because that lowers maintenance revenue.
When it comes to solid state there are a lot of interested parties researching it. As they should. But the hype has been hot and hard for years and shows no signs of letting up. Just as a recent example [2]:
John O'Dell said:
But solid-state batteries will increase energy storage without adding weight or bulk. That will extend the range of electric vehicles. They also eliminate the flammability issues that are inherent in lithium-ion batteries.
The technology is advancing rapidly and could be ready for commercial use within a few years. That’s the assessment of a report from ABI Research, a New York-based advanced-technologies research firm.
"could be ready within a few years" -- yeah, sell $TSLA because in a few years there
could be an improvement in battery technology. Of course, next year Tesla is planning on talking about
their battery developments, but that isn't important.
As for summer games, I guess you are referring to this [1]:
Shigeki Terashi said:
If possible, by the time we have the Olympic games next year, we would like to make sure that a solid-state battery can be unveiled to the public.
Wow. "if possible" "we would like". Maybe someone who is more knowledgeable about Japanese culture can help me, but to a westerner those weasel words completely undermine the statement and suggest a more accurate/honest statement would read, "After nearly ten years of minimal results from research into solid state batteries we hope to demonstrate a proof-of-concept low capacity battery for a hybrid."
So Toyota, notorious for resisting any EV production is
finally talking about making some. For China (and Europe). Because they have to. [3]

This accelerated EV push is a direct response to tougher emissions requirements in China and Europe. Toyota will start making EVs for the Chinese market next year, with plans to release at least 10 EV models worldwide by the early 2020s.
So Toyota will start making these solid state battery powered EVs next year? The same year they plan on revealing their first public demo of a solid state battery? Or perhaps this has to do with the Toyota/Panasonic partnership and nothing to do with a not-yet-ready-for-use-in-an-EV solid state battery? [4]
Fred Lambert said:
Toyota and Panasonic have confirmed that they are starting a wide-ranging new battery joint-venture to manufacture and sell battery cells for electric vehicles.
I seem to have lost the links I had for tracking actual progress on solid state batteries, but to give an idea about how difficult they are to develop: [5]
Unfortunately, the characteristics of a solid-state battery for EV use can’t be described yet, because no one has produced such a battery of the appropriate size and cost for an electric vehicle.
“That is exactly the problem,” says Dr. Milan Rosina, Senior Analyst, Power Electronics & Batteries, within the Power & Wireless division,
Yole Développement (Yole). “We can describe different approaches, both on materials and manufacturing level, but we need more data from the testing of the whole battery-cell stack and about the design and components of the battery stack (including thermal management, BMS, etc.).
Toyota (and many others) have been researching solid state for many years now. Maybe a breakthrough against the fundamental constraints that prevent them being useful for EVs has been made. Maybe. In the meantime, Toyota's 10-year plan is expiring and they have to show
something for it. But it appears that the EVs they are forced to make will be powered by lithium-ion prismatic cells made by Panasonic.
