MG's Semi Solid State Battery

[tsedge]

Slightly confused here by those statements as NMC is more energy dense than LFP.
So if SSS is the same energy density as LFP, then how does a 54 kWh SSS have the same range as 64kWh NMC ? After all a kWh is a kWh regardless of being SSS, LFP or NMC.

The 64kWh pack isn't in the same car - there's no 64kWh option for the MG4 Urban at present. The MG4 Urban is significantly more efficient than the (refreshed) MG4. The standard 54kWh LFP MG4 Urban has a quoted range of 250 miles, only 30 miles less than the MG4 64kWh with NMC, so the range improvement isn't massive.

The Octovalve and other improvements make this new platform a significant step forward.

Future versions of the SSS battery are promised with up to 400Wh/kg, but this first generation is around 180Wh/kg (more typical of LFP than NMC).

Is it just my mind... or do others think a semi solid state battery sounds as if it will be a bit of a disappointment?

It will underwhelm initially but there's good potential. The question is whether other battery types or chemistries will overtake it.

It is a bit like all of these things: we are told Sodium batteries are the future due to their price potential, but when???

Don't forget, in China they no longer sell the regular MG4, the Urban is the replacement, so they could produce an XPower variant using a SSS battery (good for rapid discharge).

Now that would be interesting.
