The difference between a lithium battery and an alkaline battery is:
1. The definition is different: “Lithium battery” is a kind of battery that uses lithium metal or lithium alloy as negative electrode material and uses non-aqueous electrolyte solution. The alkaline battery is a battery in which manganese dioxide is used as a positive electrode, zinc is a negative electrode, and potassium hydroxide is an electrolyte.
2, the characteristics are different: lithium battery energy is relatively high, long service life, the service life can reach more than 6 years, the rated voltage is high, about equal to the series voltage of 3 nickel-cadmium or nickel-hydrogen rechargeable batteries. With high power endurance and low self-discharge rate, this is one of the most outstanding advantages of the battery, generally can be 1% / month or less.
The alkaline battery can output less current than a normal battery. The capacity of the alkaline battery will become smaller as the output current increases. For example, the same battery can have a capacity of 3000 mAh at a low output current, but when used for a negative load of 1 A current, the capacity will only be 700 mAh, which is smaller than the original. 1/4.
