How To Make A Lithium-Ion Battery At Home?

Although lead-acid batteries still dominate the market, people are slowly starting to realize that they’re not a long-term solution. You can’t just throw them away once they complete their life span, as the electronics and acid can damage the environment. According to the UN Environment Program, more than 86% of the world’s total lead production goes into making lead-acid batteries. That poses a significant threat to biodiversity if any of these find their way to a landfill.

As such, adopting lithium-ion batteries is a viable way to prevent an ecological disaster. Yet, they are more complicated to manufacture and, therefore, more expensive to procure. Moreover, your nearest store may not have the one that perfectly suits your energy needs. But you can reduce the costs by making one yourself using readily available equipment. Here’s a short guide on how to make a lithium-ion battery at home.

  1. Copper metal (100×20 mm)
  2. Aluminum metal (100×20 mm)
  3. Paper charcoal dust (a little)
  4. Sugcooking oilar (a little)
  5. cooking oil
  6. Mix the 3 mixtures (3,4,5) together
  7. Heat the 3 mixed mixtures to get the precipitate
  8. Glue the precipitate between two pieces of aluminum and copper, then heat it with a gas torch until smoke is removed, then let it cool for 10 minutes
  9. Use an ampere meter to check vol.
  10. Those are the steps to make a simple lithium battery, you can attach a small capacity motor to see the operation of the homemade battery.

Creating a lithium-ion battery by yourself is pretty straightforward, primarily because you’re not building it from the ground up. Instead, you have to take multiple small voltage cells and combine them together in a way that lets you have a desirable power supply. Moreover, it helps to follow a few precautions so that you don’t burn the battery during assembly or use.

  • Insulated gloves and goggles that are resistant to welding metal
  • 15A fuses (the current can vary with the type of cells in your battery)
  • Fireproof work tabletop
  • C02 fire extinguisher

Once you have all the safety equipment ready, you can start building your lithium-ion battery at home. You need to go through the process mentioned below for the same.

  1. Analyze your energy requirements and prepare a chart to determine how you can get the appropriate voltage and current. It lets you invest the appropriate resources in purchasing the cells required for the job. Usually, the 18650 type is best, as it can handle extreme temperatures and comes with inexpensive replacements.
  2. Place the required cells in a battery holder. Ensure that you leave one row with the positive terminal up and the alternate with the negative.
  3. Use nickel strips of suitable length to make the terminals. Keep in mind that one strip has the same potential for all the cells connected to it. Thus, measure the voltage and current with a multimeter before spot-welding the strips in place.
  4. Solder conducting wires at each end of the strip. Only solder one end, as you have to connect the other to a battery management system.
  5. Avail of a suitable battery management system (BMS) and tape it to the side of the battery.
  6. Connect the suitable voltage ends to the voltage denoted on the BMS. Again, use a multimeter to make sure you have the correct wires.
  7. Solder two wires to the positive and negative ends of the BMS. Those shall serve as the terminals of the battery.
  8. Cover the battery in filament tape and seal it with an insulation cover. You can wrap a plastic bag and use a blowtorch to fix it in place.

And there you have it! Your homemade lithium-ion battery is ready to go. Just remember to store it in an isolated area and not let it overheat. It shall serve you well for up to 5 years, which is when you might need replacement on the cells.

How Much Does It Cost To Build a Lithium-Ion Battery?

It depends upon the specifications of the battery you’re trying to assemble. Provided you get the lithium cells at wholesale rates and outsource the welding and electrical jobs to a professional, it will cost you around $200 to build a 12V lithium-ion battery at home.

That is about half of the commercially available batteries of the same capacity. Although, they come with a decade-long warranty and are more convenient to repair in case of any damage.

Frequently Asked Questions

Can You Make Your Own Lithium-Ion Battery?

Yes. You can make a lithium-ion battery on your own by combining individual cells. That gives you more control over the current and voltage output, alongside convenient replacement of any faulty parts.

What Is a Lithium-Ion Battery Made From?

A lithium-ion battery has three essential components: the electrolyte, the terminals, and the protective case. The electrolyte is the most expensive component, typically utilizing a paste of lithium carbonate or lithium phosphate. The terminals are made from an alloy of nickel, aluminum, and cobalt. The protective case has a conductive layer on the inside with insulation to protect it from external contaminants.

What Metals Make Up a Lithium-Ion Battery?

A typical lithium-ion battery has the following metals within its composition.

  • Lithium


  • Aluminum


  • Cobalt


  • Nickel


  • Steel, brass, or silver in the case, depending on the application


Sometimes, the terminals are made from iridium. That ensures an extended lifespan and resistance to corrosion.

What Is the Most Expensive Material in a Lithium-Ion Battery?

Lithium carbonate is the most expensive material in a lithium-ion battery. A ton of lithium carbonate purified enough for use in a battery can cost more than $80,000 per ton. It’s a 496% rise on its 2021 cost when it was around $15,000.


Unless you have no other way to obtain commercial lithium-ion batteries, building one by yourself might be your only option. We hope this guide provided you with enough information on how to make a lithium-ion battery at home. Still, if you’re uncomfortable working around complicated electricals, it’s best to approach a professional technician to take some of the load. It might be a bit more expensive, but you ensure safety for yourself and your loved ones.
