The cost of lithium from the ocean
>That is about 3 times the current price
So if the demand actually drives the price of lithium up so much then the ocean extraction becomes viable. And as shown elsewhere this does not increase the cost of the battery compared with the cost of the product.
So in conclusion on current demand ocean extraction is uneconomical. However if this product takes off then ocean extraction does become viable and does not affect the cost by a significant amount.
