Circuitry in a battery pack, such as a gas gauge, needs to measure the battery-cell stack voltage at all times. This drives the decision to place the Li-ion protector FETs between the ground connection of the battery electronics and the negative pack terminal. This decision creates two design issues that can exist when the Li-ion protector FETs
What is a battery? A battery is an electrochemical cell that converts chemical energy into electrical energy. It comprises of two electrodes: an anode (the positive electrode) and a cathode (the negative electrode), with an electrolyte between them. At each electrode a half-cell electrochemical reaction takes place, as illustrated by the figure
An electric battery is a source of electric power consisting of one or more electrochemical cells with external connections [1] for powering electrical devices.
