![]() ![]() LiFePOĤ was then identified as a cathode material belonging to the polyanion class for use in batteries in 1996 by Padhi et al. Goodenough first identified the polyanion class of cathode materials for lithium ion batteries. Notably, the energy density of Panasonic’s “2170” NCA batteries used in 2020 in Tesla’s Model 3 is around 260 Wh/kg, which is 70% of its "pure chemicals" value.Ĥ is a natural mineral of the olivine family ( triphylite). ![]() The energy density of an LFP battery is lower than that of other common lithium ion battery types such as nickel manganese cobalt (NMC) and nickel cobalt aluminum (NCA), and also has a lower operating voltage CATL's LFP batteries are currently at 125 watt hours (Wh) per kg, up to possibly 160 Wh/kg with improved packing technology, while BYD's LFP batteries are at 150 Wh/kg, compared to over 300 Wh/kg for the highest NMC batteries. With patents having started to expire in 2022 and the increased demand for cheaper EV batteries, LFP type production is expected to rise further and surpass lithium nickel manganese cobalt oxides (NMC) type batteries in 2028. Chinese manufacturers currently hold a near monopoly of LFP battery type production. As of September 2022, LFP type battery market share for EVs reached 31%, and of that, 68% was from Tesla and Chinese EV maker BYD production alone. The lithium iron phosphate battery ( LiFePOĤ battery) or LFP battery ( lithium ferrophosphate) is a type of lithium-ion battery using lithium iron phosphate ( LiFePOĤ) as the cathode material, and a graphitic carbon electrode with a metallic backing as the anode.īecause of their lower cost, high safety, low toxicity, long cycle life and other factors, LFP batteries are finding a number of roles in vehicle use, utility-scale stationary applications, and backup power. There’s a list of trusted NRTLs that is readily available.Type of rechargeable battery Lithium iron phosphate battery CCC, RoHS, FCC, these are all junk markings they put on stuff to confuse you. If you see “CE” as the major marking, that means they can’t qualify for a proper UL listing or other NRTL. or fill the house with toxic smoke so you’re dead before you even wake up. A million things, like using the wrong plastic in the case, so it won’t self-extinguish and will accelerate a fire. It’s never been inspected by an independent testing lab like Underwriter’s Laboratories (UL), and it shortcuts all the design standards that keep us safe (e.g. That stuff is a sea of cheap Cheese junk, and it’s not about American jobs, it’s the fact that direct mail bypasses the product-quality and safety laws that make it illegal for Home Depot to sell that crud at retail. If it says “Sold by and Fulfilled by Amazon”, then don’t attach it to AC mains power! If it says “Ships from and sold by “, then don’t attach it to AC mains power! Well, if it says “Ships from and sold by ” it’s probably alright, but there have been some counterfeiting problems on popular items. Don’t buy mains electrical gear off Amazon Return it for sure! If you’ve never done Amazon returns, there are several easy ways, including any UPS Store will take them even unboxed - just the loose item and the return slip off your phone, which they scan. Read below, and if you were ripped off with non-UL-Listed cheap junk, make them pay. The power supply is either too small for the job, or is defective. Since the lights work on the battery charger (and it may be overloading the battery charger but most of them tolerate it for short times), we know the issue is the old transformer and new power supply. Your battery charger test reveals the problem The landscape lights do not care if they are AC vs DC. We don’t even bother calculating it differently, honestly. If you’re at a specific voltage, AC doesn’t help at all. You probably have a switching power supply. Also, transformers are made of copper and iron, and are quite heavy. Therefore, that DC power supply you got is not a transformer. ![]()
