You can get all kinds of (very questionable) highs from tons of OTC drugs: diphenhydramine (benadryl/zzzquil), dextromethorphan (Robitussin), doxylamine (NyQuil)...
BYD has raised lithium-iron phosphate Wh per liter up to lithium-ion levels. Wh per kilogram is still maybe half that of lithium-ion.
BYD "Blade battery 1": 168 Wh/kg. 448 Wh/L. Shipping now.
BYD "Blade battery 2": 210 Wh/kg. Announced for 2025. [1]
Tesla current lithium ion battery: 260 Wh/kg. 416 Wh/L[2]
(Tesla also uses lithium iron phosphate, in their lower-end cars.)
Close on size, big difference on weight. Weight differential is narrowing.
At this point, all fixed installations should be lithium iron or better. There's no excuse for big lithium-ion battery fires such as Moss Beach and the Port of Los Angeles any more.
Solid state batteries with better density are coming along, but nobody has those in volume production yet.
(Incidentally, if you ask questions like this to search engines that use an LLM, the results may be bogus, as they tend to pick numbers from the wrong places. Check the references.)
On Smartphone, First generation silicon-carbon battery, or lithium-ion battery with a silicon-carbon anode is shipping already at ~23% higher capacity. 2nd Generation is shipping this year at 40% increase over original. And hopefully 50% next year. With expected 100-200% increase by 2035.
> "Wh per kilogram is still maybe half that of lithium-ion."
At the pack level, it seems to be a lot less than that. If you compare a Tesla Model Y standard range (with LFP pack) to a Model Y long range (with NMC), you're looking at around 62 kWh vs 80 kWh for the latest versions, putting the difference in energy density at < 30%.
Lithium-ion is an umbrella term that properly includes common cell chemistries like lithium iron phosphate (LFP), lithium nickel manganese cobalt oxide (NMC) and lithium nickel cobalt aluminium oxide (NCA).
It doesn't make sense to compare LFP vs. lithium-ion, because the first is a sub-type of the second.
Most commonly when people say lithium ion they really mean lithium polymer (lipo). Usually for the other lithium ion chemistries they will specify like you Jane (LFP etc).
You are technically correct - that's just how I've seen it casually used
Yes you can be a pendant about a topic to a degree that you manage to confuse even yourself, or you can understand the term is also commonly used to refer to the typical metal oxide cathodes we all are familiar with (NMC, LCO, NCA, lipo). From context it's really the obvious interpretation.
LFP Tesla 3's is what they ship from China. Australia gets Chinese made Model 3's, so they are all LFP. The US doesn't get Chinese made Tesla's, so no LFP for you.
It doesn't seem to effect things much. The cars still have the same range. I guess they must be heavier.
Australian drive their cars around 13,000 km's per year. If the LFP battery got 3,000 cycles that's 90 years. I guess they must hit some other limit long before then.
> Tesla is known to frequently change the prices or availability of its models without providing separate information. As the US publication Electrek writes, the Model 3 Standard Range disappeared from the US configurator at the beginning of October. At 39,000 dollars, this variant was the cheapest Tesla in the US. Recently, however, only the Model 3 with the larger Long Range battery has been available there – in the rear-wheel drive version from 42,490 dollars. There is also the Model 3 Long Range with all-wheel drive (47,490 dollars) and the Model 3 Performance (54,990 dollars).
Most Chinese-built EVs use LFP. And China is the world's largest EV market, bigger than the rest of the world combined. So presumably, the majority of EVs shipping globally are using LFP batteries today.
Absolutely. Likewise most of the battery-electric buses in London (and presumably, other European cities) have always used LFP. Safety is a big consideration there as nobody wants a bus-sized battery fire in the middle of a dense city.
LFP has made huge energy density improvements in recent years, so the difference is much less than that today.
If you compare a standard range Tesla Model Y with LFP pack, the newest LFP pack stores around 62 kWh, vs. around 80 kWh for the long range (NMC) variant. And the LR pack actually weighs more than the LFP one, putting the difference in energy density at <30%.
Further more, typically with an NMC pack it's recommended to only charge to 80% for day-to-day use, to reduce long-term degradation. But with an LFP pack you can routinely charge to 100%. So the effective difference in range for day-to-day driving if you follow that recommendation is small.
LFP is a type of lithium ion battery. Modern LFPs perform pretty well, though they're a bit worse than "regular" lithium ion, in part because they run at a lower nominal voltage of 3.2 volts rather than 3.6 volts. They're used in cars all the time, just not usually in the United States.
I've never heard of an LFP smartphone battery, but that doesn't mean it isn't done. I wouldn't be surprised if it was common in China.
No, LFP is one form of Li-ion battery, along with other chemistries like NMC, NCA, LMO, etc.
> "LFP is incredible, but LFP batteries are 5x larger than li-ion."
Nope. Today it's more like 20-30% less energy density. And the gap has been closing over time.
> "You won't find LFP batteries in cars"
Absolutely false. The vast majority of Chinese-built EVs (brands like BFD, NIO, MG, XPeng, Geely) use LFP in many models. Most Chinese-built Teslas use LFP packs. Tesla's Powerwall 3 home storage batteries use LFP. Western automakers are also increasingly looking to LFP to reduce costs and improve stability and safety.
In fact, I'd say the significant majority of all EVs shipping in the world today contain LFP batteries.
This is completely wrong. Anyone who has bought a single LFP cell knows they are close but not quite as energy dense for the weight as regular lithium ion batteries. They are very common in all sorts of applications like medical devices and cars at the very least.
You won't find LFP batteries in cars
This is also not true at all. Here is a list of 42 car models with LFP batteries including telsa model 3, model Y and the ford mustang.
Nope! Third party launchers work just fine in GOS and other custom roms, with gesture navigation as well. The tough thing is that animations don't work well, at least in my experience. Most of the very slick "return to home" animations break on non-stock launchers, and it introduces stuttering on returning to home unless you're using 3-button navigation.
I probably wouldn't use an alternative launcher with those caveats attached. It seems the awkward animation thing may be a consequence of an Android security feature:
> Why is the recent screen buggy?
> Unfortunately, it is because the system launcher handles the Recents screen. Therefore, if you change the default launcher, weird things can happen [...] The only way to fix this is by having a Magisk module called QuickSwitch.
That isn't how that works. That isn't how any of this works.
21% [1] of homeless have a serious mental illness that predates their living situation, of which an even smaller chunk is schizophrenia. The major reasons for homelessness are predominantly financial (also [1]). We think that the sequence of events is mental illness/drugs → homelessness → poverty, but the true sequence is an averse financial event + lack of support → homelessness → mental illness (as a result of the homelessness) → drugs to cope.
We saw the most pronounced examples of this in Houston's homeless program, which has a 90% success rate by providing housing first [2]. For many, having a safe home is the only resource needed to get clean.
Homelessness is torture. Anyone in that situation would turn to drugs to cope. Demonizing the drugs is flying straight over the cause of the drugs themselves. If you want to fix homelessness, give homeless people homes.
Do you have a source that suggests that mental illness/drugs do not contribute to becoming homeless?
> 21% [1] of homeless have a serious mental illness that predates their living situation
This seems to suggest that mental illness does lead to homelessness. I would agree that financial strain is a major cause of homeless, but it seems likely that this is because it leads to other behaviors that then lead to homelessness. And those behaviors are probably not exclusively caused by financial strain.
Additionally, from the conclusion of your first link (my italics added for emphasis):
> SAMHSA utilizes its national surveys and grantee data to create effective programs and services to prevent and end homelessness among people with mental and substance use disorders.
Secondly, I agree that housing is an important first step for fixing homelessness because it seems like a precondition for stability.
But this:
> For many, having a safe home is the only resource needed to get clean.
seems misguided to me. "Housing First" != exclusively housing. From your second link:
> we move people into permanent housing as quickly as possible and then provide them with supportive services (like case management, health care, substance use counseling, income coaching, and more)
There definitely are people who have mental illness, which when activated or exacerbated leads to homelessness. I have family members in this boat and I've seen this cycle repeat at least a half a dozen times.
It will pretty soon be possible to turn off top tabs in Firefox without this kind of userChrome jiggery-pokery. The sidebar API has been updated in Firefox Nightly 131, and it provides a side tab bar, and the ability to disable the top tab bar. Existing sidebar tab extensions will be able to update to this API.
