Solid State Batteries: What You Need to Know

Solid state batteries are the next big breakthrough after lithium-ion batteries have already been around for quite some time. Here, we will talk about solid-state batteries and how they work. This article will also delve into how much more efficient they are in comparison to the first generation of lithium-ion batteries:

What is Solid State Battery?

A solid-state battery is a rechargeable battery that utilizes solid electrodes and a solid electrolyte rather than the liquid or polymer gel electrolytes seen in lithium-ion or lithium polymer batteries.

Although solid electrolytes were invented in the nineteenth century, it was not until the late twentieth and early twenty-first centuries that increased interest in solid-state battery technologies, particularly in the context of electric cars, beginning in the 2010s.

What is the Difference between a Lithium-ion Battery and a Solid-State Battery?

According to Cosmos Weekly, the electrolyte is the main difference between a lithium-ion battery and a solid-state battery. A lithium-ion battery has a liquid electrolyte, while a solid-state battery contains a solid electrolyte.

The liquid electrolyte enables the current to flow from anode to cathode. This battery is also lightweight and compact and has a higher energy density, ideal for smaller devices. Additionally, these batteries should have a longer lifespan.

What are some of the Advantages of These Batteries?

Light in Weight

In comparison to liquid-state batteries, a solid-state battery is smaller and lighter. Because of this, the car can have fewer restrictions and more features placed into it because these batteries are known to charge more quickly.

A Safer Alternative

Another significant advantage of a solid state lithium battery is that they are safer. Because there is no toxic liquid involved, they are environmentally friendly and do not create the heat that conventional rechargeable batteries do. They can also recharge more quickly.

The ions could move from cathode to anode much more quickly, and they could provide 500 percent more power than conventional rechargeable batteries. In addition, they can be more stable than traditional batteries, which makes them an ideal choice for use in vehicles.

Have a Longer Life Span

Compared to aqueous batteries, they can last much longer. In addition to this, they don’t suffer from electrode corrosion or a solid layer of electrolyte. Aside from that, they can be recharged up to seven times. This means that they can even last up to ten years, which is more than enough time for the average person to drive a hybrid.

They Have a High Energy Density

They are capable of delivering more energy per unit volume. Due to their higher energy density than liquid-state batteries, they are a better choice for automobiles. Researchers have found that these solid-state batteries are theoretically superior to liquid-state batteries and better for cars.

Have a Higher Stability

A solid-state battery’s electrolyte is more stable than a conventional battery, which can withstand more discharge cycles. In addition, these batteries can be recharged up to seven times more. Their lifespan is expected to be up to ten years, which is significantly more than what an ordinary AA battery is capable of.

The downside of Solid State Batteries

There are a few roadblocks to this technology’s future development that academics and scientists should be aware of:

This is a relatively recent development. Solid-state batteries are still in their infancy, and there is a lack of information on how they work.

Cold weather makes it impossible for cars to heat this battery to 60 degrees Celsius, which is the minimum temperature.

Dendrites form when this battery is used, producing these stick-like formations. As a result, the battery will degrade at a faster rate. Short circuits and malfunctions can occur as a result of these design flaws.


Solid state batteries could be the future of the battery industry, offering ten times the capacity in the same size package. But that’s not to say they are perfect. There are many unknowns right now, especially with the new technology. As time goes on and more research is done, solid-state batteries will start to displace traditional Li-ion batteries as they become more cost-effective. Today, though, only time will tell if they can match their competitors in terms of cost and overall industry performance.
