Semi-solid battery

Definition

A semi-solid state battery is like a mix of two types. It combines a solid-state battery and a traditional lithium battery. Scientists say it uses both solid and liquid electrolytes. The liquid part is small, about 10-15% of the battery’s weight. This liquid helps ions move fast and keeps the battery steady. The solid part makes the battery safer and lets it hold more energy. Semi-solid state batteries use many of the same materials as regular lithium-ion batteries. This makes it easier to make more of them than all-solid-state batteries.

Core features

Semi-solid state batteries have some special things about them. Here is a table that shows their main technical points:

Technical Feature	Semi-Solid Batteries Characteristics
Type d'électrolyte	Gel or thick liquid
Ionic Conductivity	More than solid, less than liquid electrolytes
Interface Stability	Easier to keep stable than solid-state batteries
Manufacturing Process	Easier and can make more than solid-state batteries
Sécurité	Very safe, better than regular lithium-ion batteries
Densité énergétique	High, a bit better than liquid battery
Coût	Cheaper than solid-state, but more than liquid battery

Tip: If you want a battery that is safer and holds more energy than a regular lithium-ion battery, a semi-solid battery is a great pick.

How it works

Semi-solid state batteries work in a different way than regular lithium batteries. In a normal lithium-ion battery, the electrolyte is a liquid that fills the whole cell. In a semi-solid state battery, there is a gel or thick liquid. This acts as both the separator and the electrolyte. This design helps stop short circuits and makes the battery safer. The anode often uses pure lithium metal. This saves space and gives more energy in the same size. When charging, lithium ions move through the gel and make a layer on the anode. This helps the battery hold more energy and stay safe. You can find semi-solid state batteries in electric cars and energy storage systems. They are used because they are safe, work well, and are easy to make.

Traditional lithium battery

Definition

Les lithium-ion battery is used in many things. You can find it in phones, laptops, and electric cars. It has a liquid electrolyte that moves lithium ions inside. This battery has been around for a long time. It works well and is trusted by many people. That is why it is called the standard for portable energy storage.

Core features

There are some reasons why lithium-ion batteries are popular.

• Different chemistries like NCA, NMC, and LiFePO4 change how much energy it stores, how long it lasts, and how safe it is.

• Some new cells hold more energy, but they may not last as long because they are more fragile.

• Charging too fast or in cold weather can make the battery wear out faster and be less safe.

• Do not charge a lithium-ion battery if it is colder than 0°C. Some brands let you charge slowly down to -10°C, but this is not common.

• Les battery management system, or BMS, checks the battery’s voltage and temperature to keep it safe. A good BMS helps stop overheating and fires.

• Battery failures do not happen often, but if they do, they can cause thermal runaway, which is very dangerous.

• Batteries are safer now, but there are still risks, especially in tough conditions.

Note: How you use and charge your lithium-ion battery changes how safe it is and how long it lasts. Always follow the rules from the company that made it.

How it works

A lithium-ion battery moves lithium ions between the anode and cathode. It uses a liquid electrolyte to do this. When you use the battery, ions go from the anode to the cathode. This makes free electrons. The electrons move through your device and give it power. When you charge the battery, the ions go back to the anode. The battery has an anode, cathode, separator, electrolyte, and current collectors. The separator lets ions move but stops electrons inside the battery. This makes the electrons go through your device instead. This design helps the battery store and give out energy well. Lithium-ion batteries are simpler than semi-solid batteries. They have been used in many products for a long time.

Key differences

Electrolyte type

The first big difference is in the electrolyte. Lithium-ion batteries use a liquid electrolyte. This liquid helps lithium ions move inside the battery. Semi-solid state batteries use a thick gel or paste. The gel is not fully solid, but it is thicker than a liquid. It helps ions move fast and keeps the battery steady. This design makes the battery safer and less likely to leak.

Sécurité

Safety is very important when picking a battery. You want to stop fires and explosions. Semi-solid state batteries are safer than lithium-ion batteries. Here are some key points:

• Semi-solid batteries heat up slower if something goes wrong. This gives you more time to fix the problem.

• They make less gas, and the gas is harder to burn.

• Batteries au lithium-ion can make dangerous gases like hydrogen. Hydrogen can catch fire easily.

• Semi-solid batteries are less likely to explode at normal charge levels.

Note: Even though semi-solid batteries are safer, you still need good safety designs. Both types can have problems if you do not use them right.

Energy density

Energy density means how much energy a battery can hold in a small space. If you want a battery that lasts longer, you need high energy density. Semi-solid state batteries are much better at this. Look at the table below:

Type de batterie	Gravimetric Energy Density (Wh/kg)	Volumetric Energy Density (Wh/L)
Lithium-Ion Battery	150 – 250	300 – 700
Semi-Solid-State Battery	300 – 500	~1000

Semi-solid batteries can store about twice as much energy. This means you get more power without making the battery bigger. Devices and cars can run longer with the same size battery.

Lifespan

You want your battery to last many years. Semi-solid state batteries usually last longer. The gel helps protect the battery parts from damage. You can charge and use the battery more times before it gets weak. Lithium-ion batteries work well, but they lose power faster after many charges. If you want a battery that lasts, semi-solid is a good pick.

Charging speed

Charging speed matters if you do not want to wait. Semi-solid state batteries can charge faster than most lithium-ion batteries. The gel lets ions move quickly. This helps the battery take in energy fast. You spend less time charging and more time using your device.

Coût

Cost depends on the battery type and how many you buy. Lithium-ion batteries cost less because they have been made for a long time. The process is simple and cheap. Semi-solid batteries cost more right now. The new materials and designs add to the price. As more companies make them, the cost will go down.

Technology maturity

Lithium-ion batteries have been used for many years. You see them in phones, laptops, and cars. The technology is old and trusted. Semi-solid batteries use new ideas. They are closer to being made in large numbers than all-solid-state batteries. Many big companies are working on semi-solid batteries. Soon, you will see more of these batteries. They give you more energy, better safety, and last longer. The industry is working fast to make them common.

Semi-solid state battery vs solid state battery

Structure

There are big differences in how these batteries are built. A semi-solid state battery has both solid and a little liquid electrolyte. This mix helps ions move fast. It uses a diaphragm to keep the electrodes apart. About 5-10% of the battery is liquid electrolyte inside a polymer. This design lets people use some old battery tools. A solid state battery only uses a solid electrolyte. It might have a diaphragm, but not always. There is no liquid inside at all. This makes it safer but harder to make. The table below shows the main differences:

Fonctionnalité	Semi-Solid State Battery	Solid State Battery
Electrolyte State	Hybrid: solid + small liquid	Completely solid
Diaphragm Presence	Oui	Varies
Electrolyte Amount	5-10% liquid	0% liquid
Conductivity Approach	Uses liquid for better flow	Only solid electrolyte
Production Complexity	Simpler, uses old methods	More complex
Densité énergétique	High, but less than solid state	Highest

Performance

When you look at performance, both batteries do well. A semi-solid state battery has good energy density and is safe. It charges faster than many other batteries. The small bit of liquid helps ions move quickly. A solid state battery can hold even more energy. It is the safest because it has no liquid. But it might charge slower since ions move slower in solids. If you want the most energy and safety, pick a solid state battery. If you want something easier to use and faster to charge, pick a semi-solid state battery.

Tip: If you want safety, speed, and easy use, try a semi-solid state battery.

Fabrication

Making a semi-solid state battery is easier than making a solid state battery. You can use machines from regular lithium battery factories. This means you can make them faster and cheaper. A solid state battery needs new machines and special steps. This makes it harder and costs more to make. If you want a battery that is easy and cheap to make, choose a semi-solid state battery. If you need the most energy and safety, a solid state battery is best, but you may have to wait until it is cheaper and easier to make.

Solid state battery vs lithium ion

Energy and capacity

You want a battery that can hold more energy and last longer. When you compare solid state batteries and lithium-ion batteries, you see some big benefits:

• Solid state batteries can store more energy because they use solid electrolytes and lithium metal anodes.

• Some new solid state batteries can hold about 50% more energy than lithium-ion batteries.

• Companies like Volkswagen and Samsung SDI have made solid state batteries that charge faster and let cars go farther.

• Toyota is working on solid state batteries that could let a car drive up to 750 miles on one charge.

• Solid state batteries can last for 8,000 to 10,000 charges, but lithium-ion batteries usually last for 1,500 to 2,000 charges.

Tip: If you want a battery that gives you more power and lasts longer, solid state batteries are a good choice.

Market adoption

Solid state batteries are becoming more popular, but lithium-ion batteries are still used more. Right now, solid state batteries cost about eight times more than lithium-ion batteries. This is because they need special tools and steps to make. Most solid state batteries are still being tested in small amounts. In 2024, the market for solid state batteries was worth $2.04 billion. It is growing fast, especially in Asia-Pacific countries like China, Japan, and South Korea.
