grizy I am going to repost this article you posted in the BFI here as i think this has pretty significant value to one leg of the climate change debate.
In my view this leading to more electric cars is a tipping point only.
I think the bigger play with better, more cost effective battery storage is a Distributed Energy Grid.
Texas arguably does not have to make the very expensive localized upgrades, to the same extent to their grid, if most homes have a battery wall in their garage that can store hours or a day or more, rationed energy for those critical time usage.
Instead of the gov't giving those utilities huge sums of tax payer money to upgrade (such as he Biden Infrastructure plan is proposing to do now), instead give tax credits to home builders to offset the cost of purchase and installation of an energy wall in every new build. Just defacto, put it in. And give retrofit credits to current home owners.
Plug that all into a smart grid where areas not being impacted by temporary outages can sell their stored power back to the utility for re-distribution elsewhere and also where the utilities can allow for selective shut downs in areas where demand is surging and allow people to access their stored power.
Yes the focus on 'cleaning up the base elements' of this tech need to continue to happen as mining many elements is quite bad but that notwithstanding, this is very positive IMO.

Lithium battery costs have fallen by 98% in three decades
In a few years electric vehicles may cost the same as their combustion-engine counterparts
Such technological progress is crucial for decarbonising the global economy. One of the shortcomings of renewable energy sources is their inconsistency: the sun does not always shine and the wind does not always blow. Batteries can help solve this problem by storing up surplus power when supply is high, for use when it is low. A steadier supply of electricity could eliminate the need for “peakers”—generation plants powered by fossil fuels that utilities bring online only when demand rises sharply, for example on hot days when air-conditioners are cranked up. Such carbon-belching facilities, which run only for a few hours each year, are expensive to build and run, raising costs for consumers.
Better batteries are also vital for the continued growth of the electric-car market. Since the Tesla Roadster became the first production vehicle to use lithium-ion cells in 2008, the number of electric vehicles (EVs) on the road has grown to more than 7m. Since batteries currently account for about a third of the price of an electric car, reducing their cost is vital for ensuring that EVs become competitive with conventional ones.
What accounts for lithium-ion batteries’ plunging prices? In a new paper, Micah Ziegler and Jessika Trancik of the Massachusetts Institute of Technology find that the “learning rate”—the fall in price that accompanies every doubling of cumulative battery production—has increased from 20% to 27% in the past few decades. So every time output doubles, as it did five times between 2006 and 2016, battery prices fall by about a quarter. This phenomenon is driven in part by economies of scale: as more batteries are made, producers can spread out the up-front costs of building factories, and use their influence over suppliers to push for lower prices on crucial inputs. Innovation is also important for cutting costs: Mr Ziegler and Ms Trancik find that a doubling in technological know-how, measured by patent filings, is associated with a 40% drop in price....
