Lithium-rich　layered　oxides　(LLOs)　with　“single-crystal”　structures　can　effectively　reduce　stress　caused　by　volume　distortion　and　improve　stability.　However,　current　work　has　primarily　focused　on　the　growth　behavior　of　LLOs　in　single　molten　salt　systems,　with　limited　investigation　into　the　impact　of　molten　salt　quantity　on　growth.　This　study　explores　the　growth　behavior　of　precursors　and　LLOs　in　different　molten　salt　systems　(NaCl,　KCl,　CsCl)　and　varying　salt　concentrations,　while　also　examining　the　effect　of　cations　on　LLOs　performance.　By　adjusting　the　molar　ratio　of　molten　salt　to　precursor,　two　distinct　growth　pathways　are　achieved:　a　lower　molar　ratio　promotes　a　chemical　topological　transformation,　while　a　higher　ratio　favors　a　dissolution-recrystallization　mechanism.　Additionally,　the　growth　behavior　of　crystals　is　influenced　by　molten　salt　viscosity;　higher　viscosity　inhibits　product　growth.　When　KCl　is　employed　as　the　molten　salt　with　a　ratio　of　4,　the　resulting　flake　structure　demonstrates　excellent　cycling　stability　(86.2　%　capacity　retention　after　150　cycles　at　1C),　attributed　to　a　reduced　percentage　of　spinel-like　structure.　This　work　not　only　provides　insights　into　the　crystal　growth　modes　of　layered　oxides　in　molten　salt　systems　but　also　facilitates　the　exploration　of　the　relationship　between　crystal　morphology　and　battery　performance.　©　2024　Elsevier　Ltd　and　Techna　Group　S.r.l.
