PURPOSE:To increase charge-discharge cycle performance by alloying lithium with an aluminium alloy obtained by adding titanium and boron to aluminium, and using in a negative electrode. CONSTITUTION:Two lithium sheets and an aluminium-titanium-boron alloy containing 0.2wt% titanium and 0.05wt% boron are used as negative material. A lithium sheet 3a, an aluminium-titanium-boron alloy sheet 3b, and a lithium sheet 3c are placed in order inside a negative can 1, and a battery is assembled in a regular way. The lithium sheets 3a, 3c and the aluminium-titanium-boron alloy sheet 3b are alloyed under the existence of electrolyte to form a negative electrode 3. Thereby, a lithium secondary battery having excellent chargedischarge performance can be obtained. |
