7. SUMMARY FROM LITERATURE 7

8. EXISTING METHOD The development of rechargeable batteries plays an essential role in the area of energy conversion and storage. In the past few decades, lithium-ion batteries (LIBs) have dominated both academic and industrial research, due to their high energy density and long cycle life. However, the practical application of LIBs is compromised by the safety issues, limited lithium resources, and environmental concerns. 8

9. PROPOSED METHOD 9 To replace the existing battery chemistry from current EV technology, we proposed a new cathode material namely, zinc manganese dioxide High Energy Density Long Shelf Life Fast Charging Rate Environmental Sustainability ZINC – MANGANESE OXIDE ( ZnMnO )
