Could that curve also be inversely related to the cost curve for lithium devices in general over the same period? Consumer technology drives cost of X down, X is now decent option for high-performance technology Y, sometimes tech X used in Y causes failures. This, here, if I had to guess, is probably the driver of avionics-related lithium incidents: the avx batteries share an awful lot of the supply chain with consumer batteries, and these batteries have an increasing amount of software way way way down in the assembly where auditors and mx engineers might not see. That software might be driving the cells within a particular environment / load range, and when it gets dinged outside of that range, unpredictable things happen. This is very very very very similar to root cause for an incident investigation I was party to. Military rotorcraft near "hot and high" operation limitations. Many other things were suspected because no one wanted it to be the lithium, but sure 'nuff, the microcontrollers deep down in their little battery brains were not doing what they needed to do, and didn't plug into the bus of the FMS/FMC's BMS (flight management computer's battery management subsystem)
