§What is a battery?
»»Battery is the device that transforms the chemical energy to electrical energy through the chemical reaction between the anode and cathode.
§What is the primary battery and secondary battery?
»»The primary battery refers to the battery that can only discharge and is not rechargeable. The secondary battery refers to the rechargeable battery that can be charged and used in duty-circle operation.
§What are the main components of battery?
»»The main components are: the positive plate, the negative plate, diaphragm paper, cap, can, and insulating layer.
§What is the cycle life of rechargeable battery?
»»When a battery experiences a charge and discharge, we call a cycle or a period. In the stated charge and discharge principles and the capacity decline before a stated standard, the total cycles it can undergo called rechargeable battery cycle life.
§What is battery inner impedance?
»»Battery impedance is the resistance when the current flow through an operating cell, in general the internal resistance is included both d.c. and a.c. resistance. For the rechargeable cell resistance is small and electrode is easy to be polarized along with producing a polarizsation resistance while measure d.c. resistance, the accurate value can't be measured.
