They can’t hold as much energy as Li-On. But they recharge 10x faster and have no heat issues. And are lighter.
Using these in cars would lessen range, but allow quick “fill ups” at recharging sites. The batteries would also allow much greater power recovery from regenerative braking. Right now only 20% of the potential electricity is recovered.

For aircraft the cells are lighter and simpler since they don’t have heat issues.
Used in conjunction with existing Li-On batteries, this technology could make existing platforms much more flexible.
In the story they complain the infrastructure is not there to support the batteries and there high charge rate. Which is just silly. For maximizing the charge rate sites will just have to have a block of these batteries already charged….. The battery set would act as a accumulator. Tesla has already done this on a massive scale in Australia.
