As lithium ion battery have served us quite well but we still need a better solution for it . So is there any better battery chemistry which i should research upon .
Dear Aman Singhal,
Sodium-ion Batteries (SIBs)
SIBs are the future batteries, Charge in seconds, last months and power over the air. Moreover, One of the most common materials on the planet rather than rare lithium, and they'll be up to seven times more efficient than conventional batteries.
I suggest you please do some research studies to explore some efficient anode materials for SIBs.
Regards.
Lithium-oxygen batteries have been viewed as another potential alternative to Li-ion technology.
Well alternative for lithium ion battery can be sodium-ion battery. But “Sodium-ion batteries operate at a slightly lower potential, which would make them practical for grid storage, but not for electric cars because their energy density would be relatively low.”
LITHIUM-SULFUR BATTERY CAN ALSO BE ALTERNATIVE IN FUTURE
A Li-S battery uses very light active materials: sulfur in the positive electrode and metallic lithium as the negative electrode. This is why its theoretical energy density is extraordinarily high: four times greater than that of Li-ion. That makes it a good fit for the aviation and space industries.
Fluoride batteries could be another better option as they are closer than ever to being commercialized.
Although in my opinion Li-ion batteries still have ways to go before we can count them out. There are potential electrode materials like Si which could improve the energy density several folds if the problem of expansion can be solved. Combined with potential development in solid-electrolytes and an established infrastructure, I think its safe to assume that Li-ion batteries are here to stay for the foreseeable future.
Due to the fact that the energy capasity by specific gravity and volume are higher, the advantages of using lithium-polymer batteries in unmanned aerial vehicles (UAVs), wearable and other electronic devices have been identified.
Maybe Physics could give prominence to mixed-Polyanion compounds[1] as new crucial cathode electrodes for both Lithium and Sodium Rechargeable mixed-Batteries[2].
Also, (electronics) Engineering might find challenging a new dual Voltage (in a single, union) battery, from a wise synergy of two "independent" (electrolytes//)anodes terminals, sharing, side by side, the same mixed-Polyanion cathode electrode material.
