    According to this the inventor of the Li-Ion battery has made a discovery to improve Li-Ion batteries to triple capacity and improve charging times.
    With a solid-state battery instead of a lithium-ion, charging could happen in minutes instead of hours, which would be beneficial for people charging their phones and electric cars.

    One of the interesting benefits:
    As an added bonus, the battery doesn't explode like lithium-ion batteries can.

    I think the battery manufacturers will jump on this but one significant adverse effect is that anyone who has an electric car using old technology will suddenly find that their car is the equivalent to a clockwork car in comparison once a car comes out using this new technology.

    Still bodes well for the future of EV.

    Solid state batteries have been in development for a while, If I were to place a bet I'd put them 10 years before mass-production for automotive purposes.
    They will take at least that long to become cost-competitive and we'll see them in consumer electronics long before cars. EVs are already far less likely to go up in flames than combustion car.

    I'd bet on 2nd hand EVs retaining their value as well, people are waking up to the running cost difference and there's only so many out there in the used market.

    There are a good few potential developments in battery tech.
    This is one. Timescale on their dev to Ev capacity will be another factor.
    Cannot remember exactly, but I think it's zinc/lithium will be 7 times denser, for example.
    Their use in items such as phones etc seem the early use.

    Metal Air batteries (like zinc-air/lithium-air) are much much further away than solid-state electrolytes.
    Unresolved issues with parasitic reactions and in open battery designs, contamination issues.
    When those issues are resolved Lithium-air could offer up to ten times the energy density per kg of our current lithium-ion cells.
    Given the cutting edge research in metal-air batteries is going down to the level of using customised nano-scale structures as catalysts to try to prevent parasitic reactions we're a long way from commercialisation.
