Solid-state batteries are an emerging technology that could power next-generation electric vehicles. They offer higher performance, safety, and energy density compared to traditional lithium-ion batteries. Solid-state batteries use a solid electrolyte instead of a liquid one, making them less flammable. Current solid electrolyte options include various oxides, sulfides, polymers, and ceramics. Widespread adoption of electric vehicles faces challenges like long charging times and safety concerns that solid-state batteries could help address by enabling faster charging and being less prone to fires. Technological advances are needed to improve solid-state batteries' energy density, lower their cost, and satisfy electric vehicle requirements.

3. Introduction
Solid-state batteries are an emerging trend for next-generation traction
batteries, as they offer high performance and safety at low cost. Additionally,
they have low flammability, higher electrochemical stability, higher potential
cathodes, and higher energy density as compared to liquid electrolyte batteries.

6. Solid electrolytes
Currently, there are more than 25 types of solid state electrolytes, such
as oxides, sulfides, phosphates, polyethers, polyesters, nitrile-
based,polysiloxane, polyurethane, etc.
Major difference between inorganic/ceramic and polymer solid
electrolytes is the mechanical property.
High elastic moduli of ceramics make them more
suitable for rigid battery systems, while low elastic moduli of polymers
make them more suitable for flexible devices.
Polymers are easier to process than ceramics, which reduces fabrication
costs. Ceramics are more suitable for harsh environmental conditions,
such as high temperatures.

7. Performance of the battery depends on the electrolyte. Polyether and
Lithium Phosphorus Oxy-nitride (LiPON)-based electrolytes are commonly
used in solid-state batteries.

12. Uptake of Electric Vehicles
Sales of electric cars topped 2.1 million globally in
2019, surpassing 2018 – already a record year – to
boost the stock to 7.2 million electric cars. 1 Electric
cars, which accounted for 2.6% of global car sales
and about 1% of global car stock in 2019, registered
a 40% year-on-year increase.

13. Factors affecting the uptake of electric
vehicles
Long time in charging
Few EV charging stations and short driving
range
Expensive
Safety concerns

16. Conventional lithium-ion batteries are inching towards saturation level in
terms of technology advancements. There is a need to develop an
alternative solution addressing all restraining factors for the uptake of
electric vehicles. Solid-state batteries offer multiple advantages, such as
high energy density and safety over conventional liquid lithium-ion
batteries.Technological advancements in solid-state batteries are expected to
provide improved products in terms of the overall cost of production and
performance.
