An anion is an atom or a molecule which is negatively charged, i.e. has more number of electrons than proton while as a cation is an atom or a molecule which is positively charged, i.e. has more number of protons than electrons.
Similarly, The anode, by definition, is the electrode where electricity flows into. In contrast, the cathode is the electrode where the electricity flows out of. If we look at a battery connected to a load, like a bulb for example, the electricity flows from the positive terminal to the negtive terminal. In this case, the positive terminal is the cathode, and the negative terminal is the anode. But when the battery is being charged, the electricity flows into the positive terminal instead of out of it. In this case, the roles are reversed, and the positive terminal becomes the anode and the negative terminal is the cathode.
