Figure 6: Lithium-ion rechargeable battery discharge mechanism 10 Tesla’s Roadster is comprised of an electrochemical cell with two half cells or electrodes (figure 6). The negatively charged electrode contains an overabundance of lithium electrons, whilst the positive electrode is electron deficient (metal oxide). The two electrodes are connected via an electrical wire that transports electron from the negative cathode electrode to the positive anode, in a process commonly referred to as electricity 12. The lithium combines with the metal oxide to form lithium metal oxide and release energy (Appendix A5) 11. When an electric motor is running, electrons will 10
