LCO is a cathode with a layered structure.
Identifying the negative terminal on a lithium battery is straightforward but crucial. Typically, the negative terminal is marked with a minus sign (-) or is colored black. This terminal is essential for the proper functioning of your battery-powered device, as connecting it incorrectly can lead to malfunction or damage.
It is the source of energy, and without it, the battery would be unable to deliver any power. The negative terminal, on the other hand, acts as the entry point for the electrical current to return to the battery after completing its circuit. This closed loop allows the battery to provide a continuous flow of electricity.
At the heart of a lithium battery lies a crucial component known as the battery terminal. Battery terminals serve as the interface between the battery and external devices, facilitating the flow of electrical current. Essentially, these terminals are the connection points through which power is transferred in and out of the battery.
