As a warming world moves from fossil fuels toward renewable solar and wind energy, industrial forecasts predict an insatiable need for battery farms to store power and provide electricity when the sky is dark and the air is still. Against that backdrop, Stanford researchers have developed a sodium-based battery that can store the same amount of energy as a state-of-the-art lithium ion, at substantially lower cost.

Chemical engineer Zhenan Bao and her faculty collaborators, materials scientists Yi Cui and William Chueh, aren't the first researchers to design a sodium ion battery. But they believe the approach they describe in an Oct. 9 Nature Energy paper has the price and performance characteristics to create a sodium ion battery costing less than 80 percent of a lithium ion battery with the same storage capacity.

"Nothing may ever surpass lithium in performance," Bao said. "But lithium is so rare and costly that we need to develop high-performance but low-cost batteries based on abundant elements like sodium."

With materials constituting about one-quarter of a battery's price, the cost of lithium – about $15,000 a ton to mine and refine – looms large. That's why the Stanford team is basing its battery on widely available sodium-based electrode material that costs just $150 a ton.

Sodium batteries taste better, too.

    So:

    1. enough competition (many manufacturers) in the battery market - 32 big enough to be mentioned in EV batteries alone [wikipedia.org], countless others for consumer batteries.
    2. materials is only 25% of the battery cost

    why the hell are the batteries still so expensive? Where's the 'free market fairy' when you need her?

    1. There is no free market in batteries. Batteries are heavily a heavily regulated industry. Many licenses and permits are required to manufacture batteries. There are also enormous patent barriers. Unless you are a billionaire like Elon, good luck accumulating enough lawyers and legislators to start a battery factory.

    There isn't much Lithium in a Lithium-ion battery. Goldman-Sachs claims that there is about $1000-worth in Tesla's 70kWh battery (63Kg), but I believe their figure is out by a factor of 10, and it should only be about $100. Another reason you should not believe these banks when apparently simple calculations are beyond them.

    Tesla has stated that Lithium makes up 2% of the volume in Tesla's batteries.

    Cobalt is more of a concern.

      Reading my source again, it may be that the author of the article misunderstood Goldman-Sachs.

      The article [electrek.co] claims 63Kg of Lithium Carbonate are used and that Lithium Carbonate costs ~$15k/ton. This would put the cost of the Lithium Carbonate in a 70kWh battery at about $1000.

      So it looks like the author of the article that Phoenix666 quotes has confused Lithium with Lithium carbonate.

        I honestly have no idea where the author of that article is getting Lithium Carbonate from. No, scratch that, I do, and it's because he's somehow confused the formula LiCoO2 for LiCO3. There is no Lithium Carbonate in the cathode of Lithium Ion batteries. There is (for some of them) Lithium Cobalt Oxide in the anode.

          On a second reading, and reflection, I may have been a little hasty in judging the author. I suspect the Lithium Carbonate he mentions might be the raw (lithium salt) material that is left after the salar brine evaporation process. My bad!

      What you see in a desert is impure silicon dioxide. Isolating and refining the silicon is necessary. Semiconductor grade monocrystalline silicon costs $102 to $127 per kg FOB China [alibaba.com].

      The lithium mentioned in the article is in a refined form that's ready to use.

      Because Moore's Law can be used in different ways. Either it can be used to drive down cost of the individual chip by packing more dies on a single wafer, or it can be used to maintain price by packing more transistors onto a single chip and thus maintain the die count on a wafer.

    According to this article, materials make up 60% of the cost of lithium-ion batteries and "overhead" is another ~30%. Labor and "profit" are around 5% each. The cathode materials (which includes lithium) makes up the largest portion of the materials cost (it appears to be about 20% of overall costs on the graph).

          Thanks.

          Something is wrong thought. A $200/kWh for consumer batteries is too low. I looked over the weekend and could not find anything lower than AUD1000/kWh. Granted, retail price.

            Glancing around, it appears to depend on the role of the battery. Automotive batteries tend to be more expensive (though I see estimates for $273 [thinkprogress.org] and $227 [electrek.co] per kwh in 2016). Other battery types were already well below $200 [teslamotorsclub.com] per kwh (for laptop batteries).

    why the hell are the batteries still so expensive? Where's the 'free market fairy' when you need her?

    There are three possibilities:

    1) There is illegal collusion and price fixing, among 32+ major battery manufacturers, all of which would have an incentive to turn State's Evidence to receive a monetary reward, huge positive press coverage, and imposing major penalties on their competitors.
    2) All 32+ major battery manufacturers are not ruthlessly competitive and trying to squeeze the maximum profit out of the economy (e.g. dropping prices by 5% to double their market share).
    3) The manufacturing, distribution, maintenance, and marketing process is far more complicated and expensive than it appears from the outside.

    For my money, I'm guessing it is number 3. As a side hint, how much do you think is the cost of the raw cotton and linen which comprises that $50 shirt you are wearing?
