Title: Non-aqueous electrolyte secondary battery
Inventor: MATSUI TORU
IPC: H01M10/05
Filed: 1993-10-21
Abstract: PURPOSE:To realize high ion conductivity even at low temperatures and restrain the generation of dendrite despite of repeated electric discharging by composing a solvent of a non-aqueous electrolyte having alkaline ion conductivity of ethylene sulfite. CONSTITUTION:LiClO4 is dissolved into ethylene sulfite at a ratio of 1mol/l, thus preparing an electrolyte. Two electrodes each having a lithium foil press- fitted to a nickel expanded metal are soaked into the electrolyte in an opposed manner, to be electrified at a predetermined current density. Impurity staying inside the electrolyte can be removed by active lithium, thereby improving ion conductivity. A negative electrode is composed of alkaline metal as an active material. Since a non-aqueous electrolyte has alkaline ion conductivity, it can exhibit high ion conductivity even at very low temperatures because of its compatibility.
