Organischer Elektrolyt enthaltende Lithium-Sekundärbatterie |
摘要 |
The invention provides a lithium secondary battery with improved withstanding overcharge and overdischarge characteristics which employs a cathode active material of lithium-containing manganese dioxide having a crystal structure of the Ramsdellite-type. An electrolyte combined with the cathode includes LiN(CF3SO2)2 as a solute. The solute is preferably dissolved in ethylene carbonate. A graphite or LiAl alloy is applied for an anode. LiAl alloy is corrosion-resistant, thereby improving high temperature as well as charge-discharge cycle life characteristics. |
