No. This is a false dichtomy pushed, from what I can tell, by the gas lobby. It's solar and wind + nukes or gas.
Batteries work in theory but not in practice: production doesn't scale fast enough, and that was before LLMs brought a new and growing source of power demand to the table. (I'm ignoring that grid batteries compete with transport electrification. A combination of economies of scale and common bottlenecks in construction of battery plants, irrespective of chemistry, links the pursuits.)
In the last few years, they have displaced a huge chunk of the natural gas power used in early evenings after sunset when solar drops off but demand is still high.

I firmly believe battery production can scale up very fast. Indeed, that's exactly what's been happening.
Realize that to replace all the motor vehicles in the US with BEVs would need enough batteries to store at least 40 hours of the average US grid output. This is almost certainly much more than would be needed for the grid itself.
The bottlenecks are in processing materials, forming anodes and cathodes and packaging them into cells. Processes preserved across most chemistries. There is a reason the guys who built Li-on plants are pretty good at building LFP plants, and why the guys building LFPs are making announcements about sodium.
This is the glory of industry: if the process is profitable, you can stamp out factories and generate ever larger profits, up to the point the market is saturated.
You could also buy a medium-sized lithium package now and already help with the transition, if you have the means, and then buy a full pack once the new hype tech becomes production-ready in 30 years (perhaps sooner but, with current warming, that's not something I'd wait on)
Lots of people say either or. When nuclear comes up, someone will claim we should just go all in on solar, wind and batteries. That's unworkable, so we wind up burning gas.
Even in this thread someone is saying that the problem with solar is that "if a megavolcano darkens the atmosphere... thus we should go all in to nuclear", as if it was a guaranteed event in the next 100 years.
It is almost always implied. It seems so obvious that nuclear should be replacing fossil fuels it doesn't seem worth mentioning. Unless someone says they're aiming for an energy policy of nuclear plus fossil fuels, it's probably safe to say their goal is nuclear and solar/wind/etc.
Even the volcano comment you mention ends with "For energy we obviously need all the options available."
No, it wouldn't. Batteries + renewables is proven and it works. The problem isn't a technological barrier. The problem is we need batteries for a lot of things and production can't ramp up fast enough.
Technical barriers are always also resource availability barriers, since technics also condition both usage and availability.
People picked tribes and decided it's all or nothing. I agree--that's stupid. There is a historical alignment between renewables backers and anti-nuke activists (see: Germany) that caused nuclear to polarise away from renewables. That doesn't really exist anymore. But you see its artefacts in the debate.
For energy we obviously need all the options available.
If a major volcano goes off up and darkens the sky with clouds and high winds make wind farms unsafe to operate, then nuclear is probably our only reliable power source left. It's not like there weren't multiple ice ages and warming events in the history of our planet.
There is a reason sailboats were obsoleted by the steam engine: it could tug forward in windless waters and stll make it fast enough to deliver the mail. The base load power station is the steam engine. The sailboat is the wind turbine or the PV array. Most of them need a gas fired power plant to compensate for windless or cloudy days, like newer sailboats need an engine. We could use a load following SMR in place of the gas fired plant.
