A chemical battery refers to a type of device that converts the chemical energy of a positive electrode and a negative electrode active material into electrical energy by an electrochemical reaction. After long-term research and development, chemical batteries have ushered in a wide variety of applications and applications. A large installation that can accommodate as many as a building, as small as a millimeter. Serving us for a better life all the time. The development of modern electronic technology places high demands on chemical batteries. Every breakthrough in chemical battery technology has brought about a revolutionary development of electronic devices. People in modern society are increasingly inseparable from chemical batteries in their daily lives. Many electrochemical scientists in the world are now focusing on the field of chemical batteries that are powered by electric vehicles.
Dry and liquid batteries The distinction between dry and liquid batteries is limited to the period of early battery development. The earliest battery consisted of a glass container filled with electrolyte and two electrodes. Later, a battery based on a paste electrolyte was introduced, also called a dry battery.
There are still "liquid" batteries. It is generally a very large variety. Such as large fixed-type lead-acid batteries as uninterruptible power supplies or lead-acid batteries used with solar cells. For mobile devices, some use a fully sealed, maintenance-free lead-acid battery that has been used successfully for many years, where the electrolyte sulfuric acid is fixed by silicone gel or absorbed by a fiberglass separator.
Disposable batteries and rechargeable batteries Disposable batteries are commonly referred to as "discarded" batteries. Because they are exhausted, they cannot be recharged and can only be discarded. Common disposable batteries include alkaline manganese batteries, zinc-manganese batteries, lithium batteries, zinc batteries, zinc-air batteries, zinc-mercury batteries, mercury batteries, hydrogen-oxygen batteries, and magnesium-manganese batteries.
Rechargeable batteries are different in terms of materials and processes. Commonly used are lead-acid batteries, nickel-cadmium batteries, nickel-iron batteries, nickel-hydrogen batteries, and lithium-ion batteries. The advantage is that the cycle life is long, they can be fully charged and discharged more than 200 times, and some rechargeable batteries have higher load capacity than most disposable batteries. In the use of ordinary nickel-cadmium and nickel-hydrogen batteries, the unique memory effect causes inconvenience in use and often causes premature failure.
Theoretical charging time of the battery The theoretical charging time of the battery: the battery's power divided by the charger's output current.
For example, taking a battery with a power of 800MAH as an example, the output current of the charger is 500MA, then the charging time is equal to 800MAH/500MA=1.6 hours. When the charger shows that the charging is completed, it is better to give the battery for about half an hour. The charge time.
A fuel cell fuel cell is a device that directly converts the chemical energy of a fuel into an electrical energy through an electrochemical reaction. A fuel cell uses an oxidation reaction of hydrogen at the anode to oxidize hydrogen to hydrogen ions, and oxygen is reduced at the cathode. It combines with hydrogen ions from the anode to form water. Current can be generated during the redox reaction. Fuel cell technologies include the appearance of alkaline fuel cells (AFC), phosphoric acid fuel cells (PAFC), proton exchange membrane fuel cells (PEMFC), molten carbonate fuel cells (MCFC), solid oxide fuel cells (SOFC), And direct methanol fuel cells (DMFC), etc., among which, the fuel cell technology using methanol oxidation reaction as a positive electrode reaction is actively developed by the industry.
