Nissan and Honda both have a long history of undercutting everyone else to sell compacts and both have been working on EV tech, Nissan a little more openly than Honda, although Honda does have a deal between Acura and GM in the states for battery tech.
Honda cooks forever before they release new things, but Nissan will keep cooking new small EV compacts... forever. It's just their thing.
I understand that was meant as sarcasm, but actually they have become cheaper, in the way that new cheap EV models are arriving with much better range than previous cheap models.
Maybe, but this is why I already bought an EV in 2020. By the time the battery has degraded, I hope to be able to replace them with cheaper, higher capacity upgrades.
It's just about LFP which are very common now. The new trend is sodium ion instead of lithium ion. CATL (battery manufacturer in China) is shipping those now, and they are starting to appear in some cars.
LFP is not new. It's been in cars since Fisker integrated A123's batteries. CATL and other manufacturers have been churning out LFP in volume for over a decade now.
You do realize a decade is a very short time for something at a scale this large with complex interactions that needs to be reliable, efficient and reproducible at scale. Plus long term tests take time because it is a factor to many clients to see if they can handle at least a decade.
