Solid-state batteries use both solid electrodes and electrolytes. They serve as a possible alternative to traditional lithium-ion batteries that use electrolytes of liquids or polymers. In various industries, such as automotive, energy storage, consumer electronics, industrial and aerospace, you can see the use of

Solid Electrolyte Battery.

Solid-state batteries, as they deliver high efficiency and protection at low cost, are an emerging trend for next-generation traction batteries. Additionally, relative to liquid electrolyte batteries, they have low flammability, greater electrochemical stability, higher potential cathodes, and higher energy density. The future substitute for lithium-ion batteries might be solid-state batteries.

A large majority of the world's portable devices, from smartphones to laptops, are powered by lithium-ion batteries. A typical lithium-ion battery uses a fluid between two electrodes as the electrolyte. The liquid electrolyte, however, has the ability to result in safety hazards. Lithium-ion batteries may be stronger and have more energy to store.

Their ability to store more energy while being safer to run, Solid Electrolyte Battery, a battery design made of all solid components, has gained popularity as the next major advance beyond lithium-ion batteries. Solid-state batteries would revolutionize electric vehicles (EVs) if they could be manufactured in industrial quantities, effectively increasing the drivable range or substantially reducing volume and weight.

Reasons for building a solid-state battery

· Why do we need a solid-state battery then? This is to boost the capacity of EV batteries.

· Market research companies expect EVs to replace and become the standard in the car industry with ICEVs (internal combustion engine vehicles). And to become the industry's undeniable leader, EV should have the same mileage level as the current ICEV. To do so, it is necessary to increase the battery capacity as an EV battery. 

· There are two ways to develop capacity. First, the number of batteries is increasing. But in this situation, the battery's price goes up, and too much space in the car is taken up by batteries.

· A solid-state battery's energy capacity is greater than that of a Li-ion battery using a liquid electrolyte solution. There is no chance of explosion or fire, so there is no need to have safety components, thus saving more space. Then we have more space to put more active materials in the battery that improve the battery power.

· As only a small number of batteries are required, a solid-state battery will increase the energy capacity per unit area. For that purpose, a solid-state battery is suitable for making a module and package EV battery system that requires high capacity.

Promising materials

When charging and discharging, battery electrolytes shuttle lithium ions between the positive and negative electrodes. A liquid electrolyte is used for most lithium-ion batteries, which can combust if the battery is punctured or short-circuited. On the other hand, solid electrolytes rarely catch fire and are potentially more effective. Today, most solid electrolytes in use are too unstable, inefficient and costly to be commercially viable.

Promising results

The current study shows that lithium-boron-sulfur electrolytes can be around twice as stable as the leading solid electrolytes. Stability can affect the quantity of energy a battery can store per unit weight. That can mean a longer driving range in electric vehicles.

The Solid Electrolyte Battery must be built to make the EV that goes further and runs safely.
