PROBLEM TO BE SOLVED: To provide an electrode capable of drastically improving safety during overcharging without deteriorating various battery characteristics and with excellent material selectivity, and to provide a battery manufactured using the electrode.SOLUTION: An increase in resistance of an electrode is generated by decomposing a part of a material constituting an electrode by heat generation due to overcharge of a battery, and progress of overcharging can be suppressed. Since the material decomposed by heat generation due to overheating is avoided from directly coming into contact with the material related to lithium ion movement due to charge/discharge, battery reaction is prevented from being disturbed during normal charge/discharge. Due to that reason, without reducing various charge/discharge characteristics, the electrode of the battery can be provided whose safety is drastically improved. |
