24M Unit Cell, an experimental battery that will end almost all electric car problems

The 24M Unit Cell is a new battery developed by the American company 24M. It is characterized by the fact that it does not consist of cells, but is built in a single block, improving spatial efficiency by 70% and energy density.

There is a key issue on the table to make the electric car a reality, and that is the battery. Increasing autonomy and reducing charging time are two essential aspects that make it viable. Today we are talking to you about 24M Unit Cell, experimental battery with a peculiarity that ends almost all problems electric car.

We always say that the electric vehicle still brings a few problems. One of them is the price, clearly higher than equivalent heat engine vehicles. And the price is not expected to decrease in the coming years.

Then there is the issue of charging points, which are still insufficient in Spain, although, as we tell you here, there are paradox that the charging infrastructure is sufficient for the number of electric cars that currently exist in our country. However, it is only a matter of time before it gradually increases.

But the transcendental axis on which viability is electric car It is the battery, and both the automotive industry and various technology companies are focusing all their efforts on it.

The battery, the heart of the electric car

It is often said that battery It is the heart of an electric car. It is the equivalent part of an internal combustion engine in a traditional vehicle. But the battery is also the most delicate part.

So far the main problem lies in the battery, v autonomy and charging times, to be specific. In order for vehicles to have more autonomy, larger batteries must be used, which has negative consequences: more weight, increased costs, more expensive vehicle price, etc.

In recent months, we’ve shown you several battery projects on AutoBild that try to solve these problems. For example this BYD Blade battery, able to remain virtually untouchedeven in accidents that involve drilling.

It is also very interesting Qilin battery developed by CATL, one of the benchmarks in the sector, capable of charging with much higher performance than is common in the sector. That’s right, the Chinese company assures that this new battery can recover 500 kilometers in just 12 minutes.

On the other hand, we talked to you about solid-state batteries with a range of up to 1,000 kilometers and a shorter charging time. Unlike lithium-ion batteries, solid-state They are more stable at extreme temperatures, have a higher energy density and are more compact.

We could continue with many other examples that confirm that many resources are being worked on and invested in improving the functioning of this, the heart of the electric car.

24M Unit Cell, an experimental battery that will end almost all electric car problems

In this sense, a new battery appears, currently experimental, which could put an end to almost all the problems of the electric car. ‘Almost all’ because the high price and lack of charging points would still exist, but that’s another topic.

This is a battery that has been developed 24M technologyan American company that has a significant stake in Volkswagen (not less than 25%). This battery it eliminates individual cells and modules and creates a single block that greatly increases energy density.

Batteries for electric cars consist of cells, i.e. small units that are themselves batteries. We could imagine the battery of an electric car as a collection of many cells.

Well, the 24M battery has a completely different configuration: it does not consist of cells, but unites everything into one block, into a single unit that stores all the energy.

This is achieved through 24M Electrode To Pack (ETOP) System.), which mounts the assembled electrodes directly into the package itself. This eliminates spaces and components that are not used to store energy, everything is unified into one block, thus achieving greater energy density.

New battery function

24M summarizes the features of its new experimental battery in five:

  • Performance: allows for more efficient packing of electrodes, not cells (more than 70%), as the packing volume gains efficiency of use.
  • Value– Simplifies your process, uses less materials and allows unitary electrodes to be connected in series and parallel combinations. As additional connecting components are eliminated, the overall cost is also lower.
  • Autonomy and longevity: Packaging and energy density are profitable, enabling benefits for both transport applications and stationary storage systems. This translates into greater autonomy and increased capacity.
  • Safety– The base cell and electrode construction of this 24M SemiSolid provides a higher level of safety even in the most extreme conditions.
  • Flexibility of packaging design– Can be connected in series, parallel and in combination series and parallel directly within one box, giving you configurations that are no longer limited by the voltage (V) and capacity (Ah) of the individual cell.
