(Ingenuity has) six Sony Li-ion cells with 35–40 Wh (130–140 kJ) of battery energy capacity (nameplate capacity of 2 Ah).
Landing mass: : Total: 1.8 kg (4.0 lb); Batteries: 273 g (9.6 oz);
So about half the energy density of 2170 cells.

That would be on par with the old A-123, isn't it?
Frankly I can barely force myself to read these "battery breakthrough" articles anymore. 99,9% will never be commercially feasible. The rest is decades in the future. 
By the way. Interesting story a coworker was telling me. Friend of his bought one of the Tesla Model 3's made in China. Apparently the batteries are lower quality than the regular Panasonic batteries Tesla has used. He claims the car is more than 100 kilos heavier, and has shorter range, than the Model 3's made with the Panasonic batteries. Life expectancy to be determined.
I wouldn't call it necessarily "lower quality". It's a tradeoff. On average, compared to NMC chemistry, LFPs have worse energy density, are cheaper, but more life cycles and are considered safer (less risk of catching fire). Almost all EVs in China are LFPs.
Ditto many e-bicycle batteries.
