Those that rely on batteries heavily and need super high discharge rates and capacity know that currently Lithium based batteries have many limitations.
For example, in electric cars, you must have a lot of batteries, and they are big and heavy and their capacity runs out quick. Just look at Formula E cars, that instead of changing batteries or recharging them, pilots have to switch cars!
FPV drone racing pilots like me need all the discharge rate we can get. Usually bigger batteries mean more discharge rate, but it also means they are heavier and therefore we tend to use the smallest capacity that will get us trough the race but that also gives us the discharge rate that we need.
But theres a real danger in using these batteries! As they are not solid state, in certain situations they can explode and/or burst violently into flames, like some kind of flame thrower.
In drone racing, we very easily surpass the 100 Km/h and the probability of smashing a battery into a wall is high.
A punctured cell usually has a sweet smell. As soon as we detect this smell, we have to dispose of the battery. The risk of it bursting in flames is real and we have to take precautions. We even use flame retardant bags to charge, store and transport these batteries!
Now, imagine that you can have a solid state battery that will never explode, is lighter, has a big discharge rate and has a bigger capacity?
That's what is being developed lately and one of the candidates are Magnesium-ion batteries!
Bellow I'll leave you a link that explains how this technology works and gives you a general idea of the progress already made. Hope you enjoy it.
