| 227 | Removal of dissolved lead from alkali metal chloride containing solutions | US3671187D | 1970-07-13 | US3671187A | 1972-06-20 | CUEVAS EPHRAIM A |
| A PROCESS IS DESCRIBED FOR THE REMOVAL OF LEAD FROM ALKALI METAL CHLORIDE CONTAINING SOLUTIONS BY PRECIPITATION OF THE LEAD IONS AS LEAD SULFIDE. THE METHOD INVOLVES UTILIZING AN ALKALI METAL SULFIDE AS THE PRECIPITATING AGENT IN LIEU OF HYDROGEN SULFIDE. THE USE OF ALKALI METAL SULFIDE AS THE PRECIPITATING AGENT PRECIPITATES THE LEAD IN LARGE PARTICLE SIZES RENDERING FILTRATION EASY. THE QUANTITY OF SULFIDE IONS IN THE SOLUTIONS NECESSARY IN ACCOMPLISH PRECIPITATION OF DISSOLVED LEAD IS ALSO MINIMIZED. TREATMENTS OF SOLUTIONS BY THE PROPOSED SCHEME SHOW REDUCTIONS OF THE LEAD CONTENT OF SOLUTIONS TREATED FROM QUANTITIES OF 0.6 PERCENT BY WEIGHT IN 18 PARTS PER MILLION OR LESS LEAD. THE PROCESS IS DESCRIBED IN PARTICULAR IN CONNECTION WITH THE TREATMENT OF LITHIUM CHLORIDE-LITHIUM HYDROXIDE SOLUTIONS CONTAINING CONTAMINATING LEAD IONS AND UTILIZING LITHIUM SULFIDE AS THE PRECIPITATING AGENT.

The present invention relates to a Li-rich antiperovskite-coated LCO-based lithium complex, a method of preparing the same, and a positive electrode active material and a lithium secondary battery, both of which include the LCO-based lithium complex. When a lithium complex in which a coating layer of a compound having a lithium-rich antiperovskite (LiRAP) crystal structure is formed on surfaces of LCO-based particles is applied as the positive electrode active material, the lithium complex is favorable for batteries which are operated at a high voltage, has high lithium ion conductivity, and can be applied to lithium secondary batteries which are driven at a high temperature due to high thermal stability. |

| Stabilized lithium particles include a lithium-containing core and a coating of a complex lithium salt that surrounds and encapsulates the core. The coating, which is a barrier to oxygen and water, enables the particles to be handled in the open air and incorporated directly into electrochemical devices. The coating material is compatible, for example, with electrolytic materials that are used in electrochemical cells. The average coated particle size is less than 500 microns. | ||||||
