Pourquoi les batteries de voitures non électriques modernes ne sont-elles pas au lithium-ion?

Je suppose que vous faites référence aux batteries de démarreur pour les voitures ICE.

L'acide au plomb est juste plus robuste que les batteries au lithium.

Il peut gérer de nombreuses conditions de défaut, même court-circuit sans s'enflammer. La surcharge dans une certaine mesure n'est pas non plus un problème.

They can handle a great deal more charge cycles than lithium based cells and they are not damaged irreparably by a deep discharge.

On the negative side they do produce hydrogen while being charged which needs to be vented safely and they are a lot heavier and larger for their capacity.

Ignoring the economies of scale already present in the supply chain, lithium would not necessarily cost more at current prices especially considering the cost savings from not shipping lead around. However the automotive companies know that if they switched to lithium the price would go through the roof due to supply issues. There just isn’t enough supply in the world to cover all the starter batteries being made right now, which is a lot more than EV batteries.
