A '''lithium manganese iron phosphate (LMFP) battery''' is a [[Chemistry:Lithium iron phosphate battery|lithium-iron phosphate battery]] (LFP) that includes [[Chemistry:Manganese|manganese]] as a [[Physics:Cathode|cathode]] component. As of 2023, multiple companies are readying LMFP batteries for commercial use.<ref name=":0">{{Cite web |last=Hanley |first=Steve |date=2023-05-20 |title=Gotion Introduces LMFP Battery With Energy Density Of 240 Wh/Kg |url=https://cleantechnica.com/2023/05/20/gotion-introduces-lmfp-battery-with-energy-density-of-240-wh-kg/ |access-date=2023-05-23 |website=CleanTechnica |language=en-US}}</ref> Vendors claim that LMFP batteries can be competitive in cost with LFP, while achieving superior performance.<ref name=":1">{{Cite web |last=Zhang |first=Phate |date=2022-07-12 |title=CATL said to mass produce LMFP batteries within this year |url=https://cnevpost.com/2022/07/12/catl-said-to-mass-produce-lithium-manganese-iron-phosphate-batteries-within-this-year/ |access-date=2023-05-23 |website=CnEVPost |language=en-US}}</ref>
== Specifications ==
Chinese battery company Gotion claims to have achieved weight energy density of 240 Wh/kg, a power energy density of 525 Wh/l, and a duration of 1800-4000 cycles. Weight energy density at the pack level is 190 Wh/kg.<ref name=":0" />

== History ==
In 2014, [[Company:BYD Auto|BYD Auto]] announced its intentions to offer LMFP batteries in its vehicles in 2015. As of 2023, the batteries had not been released.<ref>{{Cite web |title=Report: BYD to begin production of lithium manganese iron phosphate batteries for EVs in 2015 |url=https://www.greencarcongress.com/2014/08/20140813-bydlmfp.html |access-date=2023-05-24 |website=Green Car Congress}}</ref>

In 2022, Gotion reached agreement with the US state of Michigan on a package of incentives for building a large battery factory in the northern part of the state, despite some local opposition.<ref name=":0" />

Contemporary Amperex Technology (CATL) with its M3P battery announced plans to ship batteries in 2023, while [[Company:BYD Auto|BYD]], Sunwoda, and Eve Energy are also commercializing LMFP batteries.<ref name=":1" />

== Challenges ==
Commercializing the technology involved reducing manganese dissolution at high temperatures, increasing conductivity and  compaction density, granulation technology, and [[Physics:Electrolyte|electrolyte]] additives are all challenges faced by LMFP batteries. <ref name=":0" /> The company received a patent on its technology.<ref>{{Cite patent|number=I625888|title=Lithium iron manganese phosphate particles, lithium iron manganese phosphate powder and preparation method thereof|country=TW|pubdate=2018-06-01|assign1=HCM Co.
