A battery is an electrochemical device that directly converts the energy produced by a chemical reaction into electrical energy。
2. Primary battery
The primary battery refers to a battery that cannot be restored by a normal charging method after being discharged, and is also called a primary battery.
It refers to a battery that can be re-discharged by recharging two levels of active material by charging, also called a secondary battery。
4. Dry battery
A dry battery refers to a battery in which the electrolyte does not flow, and is usually referred to as a zinc or manganese dry battery.
5. Electrolysis cell
An electrolytic cell is an electrochemical device that converts electrical energy into chemical energy。 When the battery is charged, it is equivalent to an electrolytic cell。
6. Electronic conductor
It refers to a conductor that relies on free electrons inside the material to conduct directional motion under the action of an applied electric field, and is also called a first type conductor. Various metals are usually the first category.
7。 Ion conductor
It is a conductor that relies on the movable ions inside the substance to conduct electric conduction in an directional movement, which is also called a second type of conductor. The various electrolytes are typically the second type of conductor. Such as potassium hydroxide aqueous solution.
A substance having ion conductivity under certain conditions becomes an electrolyte.
It refers to a conductive system consisting of two types of conductors, namely an electron conductor and an ionic conductor, in series, also called a half-cell. Usually, the metal conductor portion constituting the electrode is used as an electrode for convenience.
10。 Positive / negative
In an electrochemical device, an electrode having a higher electrode potential becomes a positive electrode; an electrode having a lower electrode potential becomes a negative electrode.
