I doubt that. The innovation in lithium ion batteries was fueled by the demand for consumer electronics, laptops in particular. It’s the batteries that made electric cars possible. Tesla’s did kick off the trend of big screens in cars. I prefer buttons to touch screen interactions while driving, but many people want an iPad and Tesla made that happen.

Giving where credit's due, some of the high-discharge long-endurance Li-Ion research is done by Tesla. Other electronic devices generally converge towards slow-discharge, semi-fast charge, low self-discharge batteries. EVs are unique in their battery requirements. They demand high-discharge, high-endurance, very fast charge batteries, and Tesla did some research on that front. What's important that they were not the sole researchers in that area. On the other hand, they lack the know-how required to make cars efficiently and assemble them with state of the art methods (minimal/standardized fasteners, fatigue management, fast manufacturing with consistent quality and finishing, etc.).

  The Roadster used completely standard 18650 cells that were already in mass production.

  Tesla's manufacturing has come a long way in the past few years. In 2018, Sandy Munro famously tore down the new Model 3 with a lot of criticism for things like their excess of parts, fasteners, and welds. They made a lot of changes, including some he suggested, and now Munro tends to rave about how well they're engineered for ease of manufacture. This is a guy who gets paid by Big 3 auto companies to help improve their manufacturing. A great visual is this video of someone snapping together much of a Model Y like legos, in ten minutes by himself: https://www.youtube.com/watch?v=lawGMl8sHzc https://www.youtube.com/watch?v=lawGMl8sHzc Another fun one is Munro's comparison of the thermal management systems for a Model Y and Ford Mach-E: https://www.youtube.com/watch?v=m1kHsd3Ocxc https://www.youtube.com/watch?v=m1kHsd3Ocxc

> innovation in lithium ion batteries was fueled by the demand for consumer electronics, laptops in particular The battery chemistry and production methods didn’t change fundamentally from Goodenough’s formulation. What did was scale manufacturing. China took the lead, with A123’s tech. But Tesla showed there was demand for EVs in the rich world, and that production could be tamed such that money could be made from it. (EV batteries share little to no production footprint with cells for consumer electronics. They drain differently.) Pretty much every EV sold in America today was financed by investors looking for the next Tesla, or announced by manufacturers in response to Tesla.
