Comparision of solid state battery vs lithium - which is better

Let’s find out which battery will be a better choice.

What is solid state battery

Now most solid-state batteries use ternary lithium battery. They have become notable in the whole energy sector. Solid-state batteries can be mainly divided into three types: all-solid (without any liquid electrolyte), quasi-solid/quasi-solid (liquid electrolyte less than 5%), semi-solid (liquid electrolyte less than 10%).

Do solid state batteries last longer

Solid state batteries are receiving support from several organizations. They often last longer and have a lower risk of setting a fire. However, compared to other lithium systems, which exceed 4,000 charge cycles, the life cycles of solid state batteries are less than half as long. The primary issue is that getting proper connectivity between the cell’s layers is quite challenging.

The advantage and disadvantages of solid state battery

Solid state batteries have many positives but also downsides. For a more thorough analysis, let us examine the pros and cons.

Advantages

● Solid state batteries have a smaller solid electrolyte, increasing their energy density and making it possible to use more batteries in the same smaller area.
● Since the electrolyte inside solid state batteries is solid and has fewer dangers than liquid electrolytes, they are safer and have no risk of fire or explosion.
● Compared with traditional liquid lithium batteries, solid electrolytes do not have the risk of leakage.
● As there is no flammable substance in solid state batteries, reduced risk of thermal runaway.

Disadvantages

● It is challenging to produce solid state batteries on a big scale because the technology is still in its infancy and the transition from laboratory research to mass manufacturing is complicated.
● Since the electrolyte inside solid state batteries is solid, it is difficult for electrons to move freely with limited particle movement, cause higher resistance.
● The perfect substance for a solid electrolyte with optimum ionic conductivity is not discovered yet.
● The biggest problem may be the cost of solid-state batteries.

The advantage and disadvantages of lithium battery

Let us evaluate what makes lithium batteries exceptional and whether there are any shortcomings.

Advantages

● One clear benefit of lithium batteries is their significantly higher power density. High energy density battery technology is also necessary for electric cars.
● Lithium batteries do not need maintenance to function correctly.
● These batteries are lightweight, which makes them ideal for automobiles.
● They have a fast charging and low self-discharge rate.
● Some rechargeable batteries require priming when receiving their first charge, whereas lithium batteries do not. They come equipped, functional, and set to use.
● They have a longer life over 4000 life cycles.

Disadvantages

● It is not suited for harsh environments and is susceptible to high temperatures.
● They are expensive than other common batteies.

Compare solid state battery vs lithium – where are the differences

Since the number of electric vehicles is surging. We get to observe solid state battery vs lithium the most in this struggle.

Both lithium batteries and solid state batteries include lithium. However, some significant distinctions make their unique options the solid state battery vs lithium argument.

To further grasp the distinctions between solid state battery vs lithium, let us have a look at the following differences:

Electrolyte

The electrolyte, through which the electrons move, is the primary distinction between the two batteries. It is a liquid electrolyte in a conventional lithium battery, allowing maximum conductivity. At the same time, a solid state battery uses a solid substance as an electrolyte, which is more challenging to produce. Although it is highly safe, it lacks adequate conductivity.

Energy density and volume

Solid state batteries are suitable for electric cars for their high energy density in a small volume. However, Li-ion batteries offer the most remarkable energy densities compared to other high-quality rechargeable battery technologies. Electric cars may go farther without expanding the size of the battery pack by increasing the volumetric energy density of the batteries.

Performance

Both batteries function efficiently. However, their strengths vary depending on the conditions in which they are used. Solid state batteries have a high energy density, excellent safety performance, and a wide temperature range, which improves their viability for EV. Lithium batteries outperform traditional rechargeable batteries in terms of energy density, volt capacity, and self-discharge rate. A single cell’s longer charge retention boosts power efficacy compared to other battery types.

The application between solid state battery vs lithium

Given the differences in the batteries, it is reasonable to assume that they are appropriate for different purposes. Here are some of the primary applications for both batteries.

Applications of lithium battery

● A lithium battery shields you from traditional power loss or instability as an emergency power backup or UPS lithium battery.
● Lithium batteries are the best choice for solar panels due to their ability to charge rapidly and effectively. Solar panels generate low resistance charging, which is required for lithium batteries.
● Lithium batteries are ideal for remote monitoring systems since they have high durability and Self-discharge only 3.5% per month when your system is not in use.
● Lithium batteries also power modern, portable laptop computers and phones.

Applications of solid state battery

● Solid state batteries can used in the automotive sector to power various electric cars.
● They are also could used in satellites and the aerospace industry since they are lightweight and non-flammable.
● Potential applications for solid state batteries include implantable cardiac devices, RFIDs, wearable tech, etc.

However, it is difficult to achieve widespread use.

Which is better – solid state battery vs lithium

The discussion of solid state battery vs lithium implies that the best choice depends on the application. The applications and strengths of both batteries show that lithium is mainly used for energy storage. In contrast, solid state batteries are used for automotive applications like EV. So, you may select the one that is suitable for the task.

However, lithium batteries are a more effective, dependable, and practical alternative. Since solid electrolytes are expensive to produce and prone to breaking because of their instability when they expand and contract, you may want to avoid them. Further, solid electrolytes have difficulty achieving conductivity.

Will solid state batteries replace lithium-ion

Solid state battery vs lithium is a competitive space. Solid state batteries have a promising future due to various factors. Yet, we cannot disregard its downsides.

If solid state battery production becomes convenient and cheap, they may replace lithium batteries later in the future. However, the results can also be the opposite. Since researchers are attempting to improve lithium batteries, the future of these batteries is even more optimistic.
