Lithium ion batteries can be a fire risk, yes. But cheap ones in household devices (phones, charging packs, *toys*) are much riskier than the ones in EVs, according to Colin Peacock;

Lithium ion EV batteries are probably no riskier than a tank of extremely explosive fuel. Certainly not risky enough to justify a regressive crusade against EVs in general, which these days may have nonexplosive sodium ion batteries.

I've posted a few times about sodium ion batteries, and one of the things I've consistently said is that they're much cheaper than lithium ion;

Well apparently not at the moment. Demand has outstripped supply, pushing the price up, and as demand for lithium ion drops off relative to the well established supply, prices have dropped.

Often the enthusiasm is optimistic, but…
developments in batteries is going incredibly fast. It used to be ‘in five years’ coming up to ten yrs. These days it’s more like ‘this year’ going down to months. It makes sense to keep an eye out in these.
And SodiumIon is safe. Remember batteries are not, only, for cars. It’s going to boost the current grid problems, power outages etc. And SodiumIon is safe.
No more burning people in bad designed cars; no more toxic fires.
And now the really big ones are competing !

“Sep 25, 2025
For over a decade, China’s $300 billion battery industry has dominated the global energy future through lithium. But what if a small U.S. startup just broke that stranglehold? Meet Peak Energy, the Colorado-based company that secretly developed and deployed the world’s largest sodium-ion battery — no lithium, no cobalt, no rare earth metals.
This new sodium-iron phosphate pyrophosphate (NFPP) battery promises to be safer, cheaper, and made from abundant materials like iron, carbon, and salt. It can’t catch fire, works in sub-zero temperatures, and survives full discharge cycles without damage."

I've posted a few times in the last year or two suggesting sodium ion batteries as an alternative to lithium ion. Cheaper, safer, longer-lived, and easier to manufacture, and to recyclable at EoL. Mainly for fixed installations at this point (eg storage for rooftop solar), because the tech is new and still somewhat bulky.

I recently visited the friends who introduced me to them, as storage in their off-grid systems. They can't praise them enough.

If you're not already locked in, I highly recommend checking out sodium ion batteries.

Friends of mine got some about a year ago, ordered directly from a supplier in China, and can't stop singing their praises. They reckon they're cheaper per unit of capacity, last longer even with full cycling, and of course they come with zero fire risk : ) Also they're free of conflict minerals, easier to recondition/ recycle, and fairly nontoxic at EOL.

Sodium ion tech is a game changer. You can completely fill them and drain them without damaging them, so their practical capacity is higher than lithium ion, for the same theoretical capacity. Plus they're a fraction of the price, so you can buy much more capacity for the same price, or buy more panels with that surplus.

As a bonus, no risk of catching fire, and in theory we could make them in Aotearoa from local materials.
