Manufacturing process of sodium-ion batteries

You can watch how sodium-ion batteries are made step by step. Each part uses new technology and careful checks. VEKEN uses a trusted way to make sure the batteries work well for your business.

Material selection and preparation

First, you pick the best materials. VEKEN gets high-purity sodium and hard carbon for the anode. The team chooses layered oxide or polyanionic compounds for the cathode. These choices change how much energy the battery can hold and give out. You also need a strong electrolyte and a separator to keep the anode and cathode apart.

Tip: Good materials help the battery work better and stay safe.

Here is an easy list of the steps:

1. Sourcing: You get sodium, hard carbon, cathode compounds, electrolyte, and separator from trusted places.
2. Purification: You clean each material to take out anything bad.
3. Mixing: You mix the main parts with binders and additives to help them work better.
4. Coating: You spread the mix on thin metal foils to make the anode and cathode layers.

Electrode and cell assembly

Next, you put the battery together. The coated foils turn into electrodes. You cut them into the right shapes. You stack or roll the anode and cathode with a separator in the middle. This makes the main part of the cell.

Here are the steps in order:

• Stacking: You put the anode, separator, and cathode in layers.
• Electrolyte filling: You add the electrolyte so sodium ions can move.
• Sealing: You close the cell in a case to stop leaks and dirt.
• Formation: You charge and use the cell to get the materials ready and steady.

Quality assurance and packaging

You check each battery to make sure it is good. VEKEN uses machines to test voltage, capacity, and safety. You look at every cell for problems. Only batteries that pass all tests get packed.

Note: VEKEN’s quality checks help lower risk and make batteries more reliable.

You wrap the batteries in safe materials. You put labels with codes on each one. This lets you track every batch and keeps delivery safe.

Key points in VEKEN’s quality process:

• Machines test every cell
• People look for problems
• Labels and packaging help track each battery
• Follows world safety rules

You can count on VEKEN’s sodium-ion batteries to work the same every time. The steps from picking materials to packing make sure you get a battery you can trust.

Key materials in sodium-ion batteries

You need to know about the main materials in sodium-ion batteries. Each material has a special job. It helps the battery store and give out energy. VEKEN picks and designs these materials for good performance, safety, and low cost.

Hard carbon anodes

Hard carbon is the top choice for the anode in sodium-ion batteries. Its special structure lets sodium ions move fast and store well. Hard carbon comes from things like lignin, which is found in plants. The closed-pore structure helps the battery hold more energy and charge quickly.

• High reversible specific capacity (up to 358 mAh g−1) means more energy can be stored in each gram.
• The porous structure lets sodium ions go in and out easily, so charging is faster.
• Lignin-based hard carbon has about 60% carbon and lots of oxygen groups. These help make the right pores for sodium storage.

Tip: Hard carbon’s low-crystalline form and tiny holes let sodium gather and move with less energy. This makes batteries charge faster and last longer.

New hard carbon technology has made sodium-ion batteries work even better. You can see how these changes help:

Cathode materials and performance

The cathode decides how much energy your battery gives and how long it lasts. VEKEN uses special cathode materials, like layered oxides and polyanionic compounds, for high capacity and strong stability.

O3-type nickel-manganese-based layered cathodes are good for making high-energy sodium-ion batteries for growing energy storage needs. But, tricky phase changes and slow Na+ movement have made them hard to use. This work uses a medium-entropy plan for O3-type NaNi0.5Mn0.5O2 cathode to change the covalency of Ni/Mn-O bonds. This makes the structure stronger and helps Na+ move better. The new O3-Na0.92Ni0.47Nb0.03Mn0.30Ti0.20O2 (NNNMTO) works well at different speeds and lasts a long time, so it is good for real use.

You can compare how different cathode materials perform in this table:

You get steady power and long life when you pick the right cathode materials. These choices help your battery work well, even when charging and using power quickly.

Electrolytes and separators

The electrolyte and separator work together to keep your battery safe and working well. The electrolyte lets sodium ions move between the anode and cathode when charging and using the battery. A stable electrolyte stops leaks and overheating, so your battery stays safe.

The separator sits between the anode and cathode. It keeps them from touching and causing a short circuit. It also lets sodium ions pass through. This design keeps your battery safe and helps it run smoothly.

Note: Electrolytes in sodium-ion batteries are very important because they help sodium ions move between the electrodes, which is needed for the battery to work. The stability of the electrolyte is key for stopping problems like overheating and leaks. Separators help keep the battery safe by stopping short circuits and making sure the electrolyte stays in place, so the battery works well and is safe.

You can see how each material helps the battery work:

• Hard carbon anodes store sodium well and help fast charging.
• Special cathode materials give high energy and long life.
• Stable electrolytes and strong separators keep the battery safe and steady.

When you pick sodium-ion batteries from VEKEN, you get a product made with care. These materials give you energy storage that is efficient, low-cost, and reliable for your business.

Innovations and challenges in sodium-ion battery manufacturing

Advancements in materials

Sodium-ion battery technology is getting better very quickly. In the last five years, scientists made the cathode stronger by changing NaNi1/3Fe1/3Mn1/3O2. This new cathode can store more energy and is more stable. Now, it can reach 596 Wh kg-1 based on the cathode’s weight. That is 15% better than older types. This means batteries last longer and work well in hot or cold places. These changes also make batteries safer and cost less to make. Because of this, more companies use sodium-ion batteries for big energy storage. They help keep the power grid steady and handle busy times. The batteries have a modular design, so you can pick what fits your needs. Rules and the need to cut pollution also help more people use these batteries.
