摘要:
The present invention relates to a positive electrode active material, a negative electrode active material and an electrolyte that are used alone or in combination to improve charge and discharge cycle characteristic, low temperature characteristic and safety of a non-aqueous electrolyic secondary battery, particularly a lithium ion secondary battery. Specifically, a particulate Li-transition metal composite oxide having an average particle size of not less than 10 &mgr;m, wherein [20/(specific surface area×average particle size)]=7-9, is used as a positive electrode active material.
摘要:
The present invention provides a battery pack and its fabricating method, a battery and an electronic device. The battery pack provided by the present invention comprises: an outer package, which is in a laminated form and has a conductive layer therein; and a battery cell, which has a positive electrode terminal and a negative electrode terminal and is housed in the outer package, wherein, the positive electrode terminal or the negative electrode terminal of the battery cell is electrically connected to said conductive layer at the part led out from the outer package. With the battery pack and its fabricating method provided by the present invention, the influence of electrostatic discharge can be eliminated with a more simple structure.
