TL;DR if battery technology and price continues its current trajectory, households will be able to store all the electricity they need at a price that is similar to the solar panels on the roof in just a few years from now. https://shkspr.mobi/blog/2025/09/how-big-a-solar-battery-do-i-need-to-store-all-my-homes-electricity/ by @Edent

Does anyone have a link to a reputable article, CATL press release or something about the $10/kWh Sodium-ion battery? As far as I can tell its a load of hype based on one automotive news site.
It all seems to go back to here: https://www.autoblog.com/news/china-sodium-ev-battery-shift with a claimed source of Bloomberg NEF but without a link.
Please boost for visibility, this is driving me nuts!
(Not saying it won't get that low, it probably will, but not for a few years.)

Do you have a running or sports watch that is running out of battery? I am uk based and offer watch battery replacement and button fettling as a service, to keep them out of landfill.
I know that Garmin has excellent customer service, but some people want to keep their existing watches going for longer.
I use quality components from reputable suppliers, get in touch if you want to discuss

It has taken me about 12 minutes to cool down an 18650 battery which was heating up, that it was almost too warm to the touch. The battery was in the charger which clearly doesn't properly communicate with the BMS, creating a fairly dangerous situation
The battery in someone else's hand could have spontaneously combusted into flames igniting the charger and then the wood of the table it was standing on.
I have a habit of standing up, way in the depths of the night, either because I want to go training on my race machines, or because I want to physically feel how warm the batteries are that I'm charging.
Today I'm very glad that I routinely do this, because the BMS failed, a temperature sensor is obviously absent in the charger, and the chemicals would have potentially created a runaway situation because the battery was running this hot for at least a couple of hours!
The 18650 cell delivers the energy that is needed just fine it just cannot charge to 100% anymore
Of course I have marked the cell, so I can now manually remove it from the charger
