Solid state EV battery


The current battery technology includes a Lithium-ion battery that runs everything for example tablets, phones, power banks and anything of sophistication does include a Li-ion rechargeable battery. But the size, weight, and energy density have still not changed instead there has been decreased in prices per kilowatt hr with a considerable increase in performance of such Li-ion batteries.

The current battery technology includes a Lithium-ion battery that runs everything for example tablets, phones, power banks and anything of sophistication does include a Li-ion rechargeable battery. But the size, weight, and energy density have still not changed instead there has been a decrease in prices per kilowatt hr with a considerable increase in performance of such Li-ion batteries.

Solid-state batteries have replaced conventional Li-ion batteries. These types of batteries are truly solid when compared to Li-ion batteries which have a kind of wet slurry inside which is not truly solid depending on the nature of chemistry. Such batteries are very hard as they are packed very tightly under required pressure.

 

Benefits of using a solid-state battery:

  • Better chemical and thermal stability
  • Greater energy density with approx. 80% charge in 15 mins
  • Longer battery life
  • Lower fire danger as the conventional Li-ion batteries can get heated up and even explode
  • As the structure is solid there will be no leakage which leads to a reduction in energy wastage

Drawbacks:

  • Due to expansion and contraction, the precise arrangement of ionic particles can be corrupted due to cracks in the solid structure and hence the battery fails.
  • Dendrites like root structures can grow inside the solid-state arrangement due to which the battery fails
  • Expensive

Challenge:

  • Identifying the correct atomic and chemical composition of a solid electrode for maximum efficiency which has the right ionic conductivity provide sufficient power

Hence the automotive industry can really be benefitted if the manufacturing of solid-state batteries happens on an existing lithium-ion battery. If not, the economy will not support
