Here's a breakdown of the cost of an EV battery

Batteries Technology Misc Other

Battery EVs have batteries, and we all know those batteries cost a lot of money. But just how much? And what's the actual breakdown of the cost structure for your average EV battery? That's what the folks over at Elements by Visual Capitalist set out to uncover. And they've done said uncovering in a very tidy, neatly designed infographic, that you can see below.

Here's a breakdown of the cost of an EV battery

So, the average cell cost last year was $101 per kWh. If we're talking full battery package, then it was $132 per kWh, and you can easily do the math for your particular EV (or the one you're interested in) to find out how much of its price is represented by the battery's cost, by multiplying its gross battery capacity in kWh by 132. Now $132/kWh is definitely still a lot, but keep in mind it used to be $1,200 per kWh in 2010!

As you can see in the infographic, the most expensive component of the battery is the cathode. This is the positively charged electrode, and when the battery is discharged, both electrons and positively-charged molecules flow from the anode to the cathode, which stores them until the battery is charged again.

That's why the cathode is so important, and thus why it's so expensive - it essentially determines the performance, range, and thermal safety of a battery, and therefore of the EV itself. The cathodes are composed of various refined forms of metals, depending on specific cell chemistry. Common cathode compositions include lithium iron phosphate, lithium nickel manganese cobalt, and lithium nickel cobalt aluminum oxide. The commodities in the cathode are very valuable themselves, accounting for roughly 40% of the overall cell cost.

Everything outside of the cathode adds up to 49% of a cell's cost, and of course the manufacturing process is a huge part of that - 24% in fact. The anode is another significant component of a battery, making up 12% of the cost. The anode in a Li-ion cell is generally made of natural or synthetic graphite, which is less expensive than the commodities used for the cathode.

How can they sell EV under USD 30K if battery cost so much? I think info is not accurate.

Are those already in production? Are there any cars using that type of batteries?
