Reading through @BloombergNEF's reaction to the IRA, this bullet highlights another great win for the US battery industry.
If these credits are anything like the PTC/ITC for wind, solar and storage, this will support a huge build out of the US battery supply chain.

The PTC should make US cell production competitive with cell manufacturing in China.
This could lead to the US could becoming the second largest manufacturer of lithium-ion batteries after China. Although it is probably not until closer to 2030 that the US passes Europe.

As @AndyLeachBatt points out, a feature of the PTC is that it is chemistry agnostic. This would make LFP cells significantly cheaper than nickel based cells in the US
This would encourage LFP production, despite the fact that Iron isn't included as a critical mineral

In the article, we present the most common continuum models, from the microscale model to the Single Particle Model. We also highlight the connections between the various models, and how to derive a simpler model from a more complex one (Sections 2 and 3). 2/6
After presenting the models, in Section 4 we revisit them in order of increasing complexity, discussing the additional insight each model offers and what is the computational cost to pay. 3/6
Now that @elonmusk has confirmed @Tesla will be using #LFP in some US Model 3's the normal Q's around patents and licensing have arisen.

Patent 1 - The first LFP structural patent was filed by Nobel prize winner John Goodenough in 1996, granted in 2003 and expired in 2017.
The patent described the performance of the material and its use in batteries.

Patent 2 - This was filed by the @UMontreal. It was granted in 2008, and expired earlier this year.
This described how the performance of LFP, which has a low electronic conductivity, can be improved by coating it in carbon.

Great to see the Korean Government supporting its battery manufacturers and industry by committing $35b

The trend amongst governments (Europe, U.S., U.K., China, Japan, Korea) in approaching the battery development is similar.

1) Industry-University-Research Solidarity and Cooperation (from the Korean plan)
To stay ahead in the battery industry governments are recognizing the importance of investing in early stage research on next-gen tech, but more importantly having industry and academia collaborate

1b) We see this globally, in the U.K. you have the Faraday Battery Challenge and @FaradayInst.
In Europe, @InnoEnergyEU, EBA and Battery 2030.
In the U.S. the DoE has been pivotal in developing next gen tech through @ARPAE.
In Japan the Battery Association for Supply Chain.

Last week @BloombergNEF published its first outlook for Solid-state adoption, featured in the @climate article bloom.bg/2Pal36L.

1. We expect solid-state cells to be adopted in premium EVs first because they will be higher cost than liquid based cells.
2. We expect they could be cheaper by 2033, after this point adoption in non-premium segments accelerates.
2. We expect they could be cheaper by 2033, after this point adoption in non-premium segments accelerates.
3.We modeled EV economics, assuming the increase in range for a given pack size (kWh) would be favored. But if auto's use smaller packs to achieve the same range as liquid based cells, EVs using solid-state cells could be affordable sooner. It will probably be a mix in reality.

Solid-state battery adoption will happen this decade, and cells could be cheaper than liquid based cells.

At the end of 2020, @BloombergNEF adapted its BattMan model to integrate solid-state cells.
At scale with developed supply chains, solid-state cells could be manufactured for 80% of the cost of liquid cells - with the same cathode.
When optimised they could be 40% cheaper...

A conventional cell is an 60Ah NMC (622) pouch cell manufactured in todays facilities.
Benchmark SSB is 60Ah NMC (622) pouch type solid state battery, produced on manufacturing lines of the same speed as our conventional cell. Using Lithium metal anode foil.

News came out today that the solid-state battery company #QuantumScape is going public with a valuation of $3.3B, backed by investors such as Bill Gates and VW. Little is known about their technology though, so here is a recap of what I found. cnbc.com/2020/09/03/bil… #battchat
Their main claim is that they have achieved a functional "anodeless" battery using a solid-state electrolyte. By anodeless they don't mean that the battery uses no anode, but that the anode is formed in-situ with lithium coming out of the cathode during the first charge.
This anodeless configuration would allow them to fabricate lithium metal batteries without the hurdles of using metallic lithium in the manufacturing process, therefore saving costs.
