Aluminium-ion battery that can provide up to three times the range on EVs and charge 60 times faster. This means an 8-hour charging cycle could be reduced to 8 minutes when compared to the current generation of lithium-ion batteries.
It's a direct replacement that charges so fast it's basically a supercapacitor. Lithium-ion cells can't do more than 1.5-2 amps or you can blow up the battery, but this technology has no theoretical limit. It charges an iPhone coin cell in less than 10 seconds.
Aluminium-ion batteries are also safer as there is no upper ampere limit to cause spontaneous combustion.
So far there are no temperature problems. Twenty per cent of a lithium-ion battery pack (in a vehicle) is to do with cooling them. There is a very high chance that we won't need that cooling or heating at all. Aluminium-ion batteries does not overheat and it nicely operates below zero so far in testing.
Aluminium-ion batteries will be lighter as well as they don't need extreme cooling mechanisms. They don't need circuits for cooling or heating, which currently accounts for about 80kg in a 100kWh pack.
This battery tech could be reverse engineered to work with existing lithium-ion battery housings. This means the batteries can easily fit on current generation EV platforms like MEB by the Volkswagen group.

These all sound wonderful and I very much hope they work out.
There are so many battery break throughs happening, why have we not seen them come to fruition? I refer to them as the "battery break through du jour" There have been so many of these battery break throughs, I now ignore them.
Could they really be just media hype?
@barry.hendriks Tech advancement is great.
More range from less weight means even better efficiency, but it's not so great if it comes with high cost & poor lifespan.
Charge time is currently limited more by charge-power supply, than by batteries. For example most of the fastest chargers near me are 50kW, taking over 1:15 to recharge a typical 250-mile weekly drive, even with a typical new EV that has the capability to charge faster. It would still take over 42 minutes at one of the few 150kW chargers that have gone in recently, regardless of whether your EV has Li-ion, solid state, or supercapacitor.
Aptera's extreme efficiency already gives it shorter charge time from the same supply, again regardless of battery type: 250 miles in about 30 minutes at 50kW, & about 10 minutes at 150kW.
From Wikipedia: Aluminum-ion batteries have a relatively short shelf life. The combination of heat, rate of charge, and cycling can dramatically decrease energy capacity. One of the primary reasons for this short shelf life is the fracture of the traditional graphite anode, the Al ions being far larger than the Li ions used in conventional battery systems. When metal ion batteries are fully discharged, they can no longer be recharged. Ionic electrolytes, while improving safety and the long term stability of the devices by minimizing corrosion, are expensive to manufacture and purchase and may therefore be unsuited to the mass production of Al ion devices. In addition, current breakthroughs are only in limited laboratory settings, where a lot more work needs to be done on scaling up the production for use in commercial settings.
