As　LiFePO4　(LFP)　gradually　becomes　the　leader　in　the　energy　storage　and　power　battery　field,　achieving　a　green　and　efficient　industrialized　recovery　of　Li　from　the　stable　lattice　structure　of　LFP　has　become　a　significant　requirement　for　driving　resource　and　environmental　sustainability.　Here,　a　non-acid　wet　ultra-fast　mechano-chemistry　reaction　(UMR)　instantaneous　metallurgy　technology　is　proposed,　water　leaching　has　obvious　green　and　sustainable　advantages.　Including　the　wet　mechanochemical　reaction　of　C10H14N2Na2O8　assisted　H2O2　and　water　leaching　to　deconstruct　the　orthorhombic　olivine　structure,　and　an　innovative,　detailed　explanation　of　the　mechanism　of　this　technology　is　presented　from　the　perspective　of　the　synergy　between　mechanics　and　chemistry.　The　results　indicate　that　under　optimal　conditions,　stress　energy　accumulation　and　single-factor　conditions　can　instantly　achieve　the　activation　process　of　efficiently　deintercalating　Li　and　enriching　Fe　in　a　single　step　within　4　mins,　while　still　maintaining　the　olivine　structure.　Through　the　coupling　of　UMR　with　chelation　reactions,　the　fastest　selective　recovery　of　99.17　%　of　Li　is　achieved.　Following　filtration　and　precipitation,　Fe　and　Li　are　ultimately　recovered　in　the　form　of　FePO4　and　Li2CO3　precursors,　respectively.　Grey　correlation　analysis,　grain　flows　numerical　simulation,　and　the　mechanism　of　chemical　reactions　indicate　that　rotation　speed　is　the　most　critical　factor　affecting　Li　recovery,　leading　to　the　desorption　of　Fe(III)　and　Li+　mainly　caused　by　the　wear　to　the　lattice　structure　by　normal　cumulative　force,　energy　accumulation　dissipation-induced　advanced　oxidation　reactions,　and　chelation　reactions.　The　non-acid　USMR　reported　in　this　study　offers　a　sustainable　new　pathway　for　the　rapid　extraction　of　Li　from　spent　LFP　for　industrial　purposes.
