摘要： In an electrochemical cell using a conventional thermally resistant container, there is a problem in that, when it is used at a relatively high voltage, for example, around 3 V, a metal of a collector is dissolved and characteristics thereof are extremely deteriorated. In order to prevent a positive electrode current collector from being dissolved even at a high potential, a surface of the positive electrode current collector is covered by a valve metal or carbon such that the positive electrode current collector and a positive electrode do not come in contact with each other. Therefore, in the electrochemical cell according to the invention, the positive electrode current collector is prevented from being dissolved.

摘要： A non-aqueous electrolyte secondary battery has a negative electrode, a positive electrode and a non-aqueous electrolyte with lithium ion conductivity. A composite oxide produced from a metal or a metalloid and lithium represented by composition formula Li.sub.x MO (where M represents metals or metalloids other than alkali metals, and x satisifies 0.ltoreq.x) is used as an active material of one or both of the negative electrode and the positive electrode. The battery exhibits a large charging/discharging capacity and a high energy density together with smaller polarization (internal resistance) on charging and discharging which facilitates a large current charging and discharging with a long cycle life and reduces deterioration due to excess charging and excess discharging.

摘要： A non-aqueous electrolyte secondary battery has a negative electrode, a positive electrode and a lithium ion-conductive non-aqueous electrolyte. A silicon oxide or a silicate containing lithium is used as the negative electrode active material. The potential of the negative electrode active material is low, the charge and discharge capacity in a base potential region of 0-1 V with respect to metallic lithium is large, and the polarization (internal resistance) during charge and discharge is small. A secondary battery having a high voltage and a high energy density is obtained in which large current charge and discharge characteristics are facilitated, the deterioration due to excessive charge and excessive discharge is reduced, the cycle life is long and the reliability is high.
