The initial high-voltage activation triggers an irreversible migration of TM ions into vacancies within Li layers, initiating a gradual transformation from the desired layered framework to a disordered electrochemically inferior rock-salt phase at the particle surface [24,26,27]. Concurrently, the highly oxidized LMR surface becomes extremely reactive, engaging in parasitic reactions with the organic electrolyte [30] that lead to continuous electrolyte decomposition, TM (particularly Mn) dissolution into the electrolyte, and the formation of a thick ionically resistive cathode -electrolyte interphase (CEI) that stifles kinetics [31,32]. A direct consequence of this instability is the evolution of O2 from the LMR lattice, which can trigger violent exothermic reactions with the flammable electrolyte and thus poses thermal runaway and safety risks [31 -34].", "cleaned_text_preview": "One of the biggest challenges faced by LMRs is the severe continuous voltage fading during cycling, which leads to a rapid decrease in overall energy density and thereby negates the primary advantage of these cathode ma…", "included_in_body": true, "body_decision_reason": "body", "parser_body_decision_reason": "body", "production_usage": "", "visual_asset_type": "", "visual_asset_label": "", "visual_asset_caption_preview": "", "visual_asset_anchor_ref": "", "inside_body_region": true, "body_region_id": "p2:body_region:0", "role_guess": "body", "zone": "body_zone", "column": "column_1_of_3", "column_index": 1, "column_count": 3, "flags": {"docling_non_body_label": false, "page_margin_noise": false, "metadata_line": false, "affiliation_block": false, "reference_item": false, "body_sentence": true, "body_candidate": true, "body_heading": false, "heading_kind": null, "has_front_matter_zone": false, "visual_text": false, "publisher_landing_page": false, "caption_continuation_used_by_asset": false}, "background_rgb": [255, 255, 255], "page_background_rgb": [255, 255, 255], "background_delta": 0, "background_class": "white", "is_gray_background": false, "has_frame_evidence": false, "edge_dark_ratios": {"top": 0.04, "bottom": 0.005, "left": 0.077, "right": 0.0}, "excluded_risk_level": null, "region_id": "p2:body_zone:column_1_of_3:white", "truncation_marker": ""}
