I can't believe the guy who invented LFP is named Goodenough
@EdGoodwill
China adopted LFP early on in EV transition because Chinese EVs start from buses and taxis, not fancy sport cars like Tesla roadster or Model S. Buses and taxis drive much higher mileage per year (100,000 km per year on average). So cycle life is critical, and LFP's long cycle life is essential in these applications. And that's the key reason LFP dominated BESS (battery energy storage system) market besides safety. And BTW, the Moss landing BESS fire shown in the video use ternary battery, not LFP battery.
@zeugundso
I think people underestimate the repercussions of cheap LFP storage for future engery markets. With modules below 100$/kWh and lifetimes of over 10000 cycles the thing that used to be the expensive part of battery storage now is below 1 cent / kWh stored.
@markotrieste
A small oversight in the video: LFP are not safer because of lower energy density, but because they don't let oxygen to be released during charge and discharge cycles.
@xjdisuehd
Recent quote for LFP prismatic cells, 960 watt hours (3.2V, 300Ah) was at $38 per cell, which turns out to be $39.6 per kWh at the cell level. Our liquid cooling and heating stuff that goes into it. Each cell weighs around 6.5Kg, and with our systems added into it, turns out around 6.8Kg per kWh, or a unit system level density of 147Wh/Kg. Our 40 ft containers weighing 23 metric tons of stuff and 3.9 metric tons of dead weight. 3.3MWh of energy per 40ft container. Depending upon the requirements, we typically can change the inverter container and modulate a battery container from 2 to 8 hour ranges, but about 85% of our stuff is for four hours. Another 13% is for 8 hours and remaining is for 2 and 6 hour systems. About $8500-9000 for our one-trip containers (i.e., new containers) pre-tariffs, and another $25k in materials to make it suitable and sturdy for holding that much weight and the heat generated, another $40-50k in wiring, stands, and another $40k for heating and cooling controls. All in, our typical 40ft container of 4MWh of energy costs us about ~$300k, and it sells off as fast as we could make it. The electrical control and inverter container can either be a standard 20ft or a 40ft, depending on the system design. A 10MWh system, for four hours of backup is four 40 foot containers, and can cost about $2M. Throw in another $500-750k for site installation, connecting to the grid and that gives you about $275/kWh of storage capacity cost. At $0.12-0.18 in electricity, these are the average residential electric prices where we install our systems, our systems are very much a smart business solution. It worked out even with the Biden tariffs that were supposed to go in effect in 2026 for non-EV related batteries. As far as I understand that is no longer valid with Trump's tariffs. Before the tariffs hit, we basically took out any loans that we could, maxed out our credit lines and talked with banks to extend their services on overdraft accounts for no extra charges. We are waiting on North American - and now with Trump's tariffs, US based LFP suppliers. There are some, but they do not compete on cost, rather focusing on quality required for automotive use, and I do not expect any major supplies to come online for non-automotive use till 2027 (point to remember, so much of LFP battery material is going to have to be imported from China, until we can build a supply chain for ALL of the stuff that goes into LFP batteries). I think it will be until 2030 when US sourced LFP batteries will reach cost parity with Chinese LFP batteries and by then China will be even lower or they will have mastered LMFP batteries. Update: 12th May 2025 90 day pause on 145% tariffs and to be set at 30% while China has lowered it to 10%. We plan to sell as much as we can, maybe take a few payments upfront with discounts and then use the money to move more inventory and pay off overdraft accounts and short term loans ASAP, while planning for what's next.

The big advantages of LFP are that they have about 3 times the life of the NiC batteries and can be charged to 100% without significantly degrading the battery life.
@unreliablenarrator6649
LFP is now becoming standard for mid-market EVs in China and Europe, with Sodium Ion finding application in City cars, and in the near future, perhaps cold weather EVs in hybrid battery packs (CATL in lead). Chinese have done for batteries what Japanese and Koreans did for commodity ICs and Taiwanese did for PC motherboards: engineer to price point and keep at it until the benchmark is achieved. Then accelerate.

A 2023 fire in the Netherlands also gave a small demonstration on the Blade Battery, as well as the advantages of lower intensity packing in general. At themepark Walibi Holland all EVs were parked together as a result of all chargers being put together. The chargepoints were moonlighter-built and jumped voltage all over the shop. So a Tesla (what else?) model X spontaneously caught fire due to its unstable tight packing causing thermal runaway when subjected to such extreme jumps. When it erupted the cars around it took fire pressure. A Nissan Leaf went up, half burned. A Tesla Model Y promptly also caught fire and burned to the wheels. A Renault Zoe took major fire pressure to the front, but refused to burn. Two BYD Atto3's covered themselves in glory, taking major fire pressure from the side. One of them pressured from both sides. The BYD blade battery refused to brew up in both cars and that's where the fire stopped spreading. Pictures of the damage still available on local media like Omroep Flevoland and Bergnet (towing)'s social media. So yeah, Blade packing for the win if you ask me. It was one of the reasons why I bought an Atto3 couple months later.

I have experienced this development in Thailand, where BYD reduced the price for the spare batteries and then also for the vehicles by 20-30%.
@edhorse13
'Goodenough' sounds like a great battery brand!
@Aranimda
LiFePO4 is my preferred battery chemistry for larger applications. Yes, it is a bit heavier and less energy dense. But the advantages of improved safety and much greater cycle- and calendar lifetime make more than good for that. I'm quite happy with my (Chinese) LFP batteries.
@dieselphiend
Battery grade additives are in another league in terms of processing/expense. The purer they are, the more ideal the particle size, shape, and distribution, the better your batteries will be.
@slash196
Battery modules are not arbitrary, they're a wiring step that allows you to put the right number of series and parallel connections to achieve your desired operating voltage.
@Ayooluwaigandan
After Thomas Friedman’s podcast with Ezra Klein, I’ve been looking for info about Chinas EV industry and why they have a cost advantage of US companies. Your video comes just in time.
@alexforget
Grid connected battery are very usefull as they allow better use of the existing infrastructure. Before you needed to have a powerplan, transmission lines, transformer to exceed you peak demand, now you drop a few battery storage container on you distribution station and everything upstream can now spread the peak. You get a better usage of almost all your infrastructure.
@MarkoCloud
I built a LFP battery from 4 EVE 280Ah cells for my RV. One winter I forgot to unplug the inverter that was on a BMS bypass due to the BMS being too weak for the draw. The inverter has a tiny draw and it drained the pack to about 4V which would mean the battery was entirely dead. I plugged the RV in to mains, but the charger didn't start charging. I sadly started thinking I'll need to buy a new battery. But then I simply decided that put a 3.5V charger on the cells and they started drawing amps. As many amps as I wanted but my DC maxes at 10A. So somehow within about 30 mins, the voltage was above 2.5V, in about 2 hours it was at 3V and then left them and checked about 4 hours later and they got up to 3.1V. I put them back into the RV and lo and behold, the battery started charging full bore at 30A. The battery is still in my RV and now only has about 250Ah capacity based on my testing. LFP is indestructible.
@Tore_Lund
LiFePO4 commercial production began early 90' in China. They developed the idea and market of electric mopeds and we could buy the Thundersky cells here in Europe. That was long before any Li-ion cells in vehicle size were available from anyone. In other words, China had a 10 year head start making batteries for vehicles.

This channel has hands-down the best videos of anywhere. Really well done and informative.
