There may be differences between primary and secondary batteries, so let’s introduce what primary and secondary batteries are

What is a primary battery?

As the name suggests, it is a battery that can only be used once. The battery converts chemical energy into electrical energy to provide power. The electrical energy cannot be replenished by charging or other means. Therefore, it cannot be used again after being fully discharged. The electrochemical reaction is irreversible.

Common carbon-zinc batteries, alkaline batteries, mercury batteries, etc. are all disposable batteries. Different disposable batteries have different uses, but they are all limited to single use. In manufacturing, the raw materials of many disposable batteries are polluting and have a considerable impact on the environment and human body.

What is a secondary battery?

 

Secondary batteries are reusable batteries that can be charged and discharged continuously. Secondary batteries are also converted from chemical energy to electrical energy. But they can be charged to convert electrical energy back into chemical energy, so that the battery can be used again. The number of times this type of battery is used is determined by the raw materials.

 

Common secondary batteries include lead-acid batteries, colloidal batteries, nickel-cadmium batteries, nickel-hydrogen batteries, lithium-ion batteries, lithium-ion polymer batteries, lithium iron phosphate batteries, etc. Different types of secondary batteries are used in different fields due to their rated voltage, rated capacity, operating temperature and safety.
