LITHIUM SEKUNDÄRBATTERIE MIT EINER NEGATIVEN ELEKTRODE ENTHALTEND NATÜRLICHEN SCHUPPENGRAPHIT

A lithium secondary battery has a negative electrode structure, an electrolyte and a positive cathode structure, the negative electrode structure being of at least 40% by weight of natural flake graphite, having an La-value of at least 300 nm and/or an Lc-value in the range 50-150 nm and an La-Lc-ra...

description A lithium secondary battery has a negative electrode structure, an electrolyte and a positive cathode structure, the negative electrode structure being of at least 40% by weight of natural flake graphite, having an La-value of at least 300 nm and/or an Lc-value in the range 50-150 nm and an La-Lc-ratio of at least 2, and the electrolyte having at least 10% by weight of propylene carbonate based on the weight of the solvent and salts of the electrolyte system. Natural flake graphite is compatible with propylene carbonate containing electrolytes, thereby forming stable battery configurations.
