|a Efficient utilization of resources is crucial for the sustainable development of the lithium-ion battery industry. Although the traditional R 3 ¯ $\bar{3}$ m space group LiCoO2 can provide a current advanced discharge capacity of 215-220 mAh g⁻¹ at an upper cut-off voltage of 4.6 V (relative to Li⁺/Li), it still falls far short of its theoretical specific capacity of 273 mAh g⁻¹, and exhibits structural instability and labile oxygen loss, leading to rapid capacity degradation. T#2-Li0.69CoO2 is synthesized with Cmca space group and Li─O tetrahedral coordination. Owing to the unique Li─O tetrahedral coordination structure and the dominant cobalt oxidation under high voltage, T#2-Li0.69CoO2 delivers an ultra-high specific capacity of 258 mAh g-1, close to the theoretical capacity, in liquid electrolyte batteries and 253 mAh g-1 in solid state batteries, overcoming the structural instability of layered oxide cathodes during charging and discharging processes. This study broadens the possibilities of creating high energy-density cathodes for next-generation Li-ion batteries
