in a cell voltage energy is converted to current energy and --------.

"voltage energy" and "current energy" are meaningless concepts. A cell converts chemical energy to electrical work. The work is done in some external device, such as a motor, not in the battery/cell itself. There is some heat produced in the cell, but not much.
In a cell, energy is converted from chemical energy to electrical energy. The electrical energy produced by the cell is used to drive a flow of electric current through a circuit.
To understand how energy conversion occurs in a cell, we need to look at the chemical reactions taking place inside it. In a typical cell, such as a battery, there are two electrodes - an anode and a cathode - immersed in an electrolyte solution. The chemical reactions at the electrodes involve the transfer of electrons.
At the anode, a chemical reaction occurs that results in the release of electrons. These electrons move through an external circuit from the anode to the cathode, creating an electric current. This flow of electrons represents a conversion of chemical energy to electrical energy.
At the cathode, another chemical reaction takes place, which utilizes the electrons received from the external circuit. This reaction consumes the electrons and combines them with species from the electrolyte solution, resulting in the conversion of the electrical energy back to chemical energy. This chemical energy can be used to perform work or power electrical devices connected to the cell.
So, in summary, in a cell, energy is converted from chemical energy to electrical energy at the anode, where electrons are released, and then converted back to chemical energy at the cathode. The flow of electric current through an external circuit represents the conversion of energy from one form to another.
