Yes, it is likely at some stage in the future, but significant investment in lithium ion battery technologies will take some time …the same time it would take for lithium ion adoption itself. Use in the transport sector will also slow change as this is affected by life of vehicles and the cost to change.
There has been research into higher capacity mixed metal batteries (other than lithium ion) but there hasn’t been anything yet likely to compete with current technologies and its development.
As lithium and other battery metals are mined in some of the most environmentally sensitive areas on the planet (for example the salt lakes areas in the Andes plateau), along with problematic byproducts of metal processing (highly toxic compounds, radioactive wastes, surface brine management etc), thought must be given to whether humans damaging new areas which historically have not been subject to major human interference is a good thing.
There are advocates of lithium ion battery technologies which ignore the pre-use impacts of this technology (maybe considered unavoidable ‘collateral damage’ so that their own aspirations can be achieved), but such needs to discussed when considering a favoured technology in the future.
No potential future energy technologies are perfect and have unintended consequence both socially, economically/financially and environmentally. To favour one over another without considering all the advantages and disadvantages will only lead to future headaches/heartaches. I believe that time is well overdue to consider such impacts to ensure that we can have a better and brighter looking future. I would rather have informed decisions accepted by the community as a whole rather than relying on the marketing hype of vested interests.
