When we talk about electric cars, we usually think about range, charging points, or design. But there's one element that influences everything and explains why this technology hasn't yet definitively conquered the market: the battery.
Today, the battery represents approximately 40% of the total cost of an electric car. Simply put: if the battery is expensive, the car will be too. Therefore, the true revolution of the electric vehicle lies not in the motor or the software, but in how batteries are manufactured and made cheaper.
This is a global challenge with many players. Around the world, hundreds of companies, laboratories, and research centers are trying to improve batteries: making them cheaper, longer-lasting, safer, and with higher energy density.
Experts agree on one key fact:
. 70% of the cost of a battery corresponds to the materials.
. 30% to the manufacturing process
This explains why so much research is being done on new chemistries and optimizing how they are produced. There are many possible combinations of materials for energy storage, and spectacular results are achieved in the laboratory. The problem arises when it comes to moving from prototype to mass production, guaranteeing millions of batteries that will function for years without failure. In that leap, many projects fall by the wayside.
According to numerous industry analysts, the electric car will be a definitive success when it meets two basic conditions:
. a sales price between $20,000 and $25,000
. a range of around 400 miles (about 640 km)
Today, these figures are only achieved with substantial government subsidies. And although prices are falling year after year, we are still far from the point where the electric car sells itself, without any support.
The key to getting there is clear: making batteries cheaper.
In addition to researching new chemistries—such as LFP batteries and others yet to come—there is a huge effort underway to improve the manufacturing process.
This is where a technology called dry electrode coating comes into play, considered by many to be the “holy grail” of battery production.
Its advantages are theoretically substantial:
. it eliminates the use of toxic solvents
. it does away with giant drying ovens up to 100 meters long
. it reduces energy consumption by around 50%
. it decreases the required factory space by up to 70%
Less energy, fewer facilities, and less complexity translate directly into cheaper batteries.
Companies like Tesla, Volkswagen/PowerCo, LG Energy, and many others are constantly announcing new generations of more efficient and economical batteries. However, history shows that bringing an innovation to market always takes longer than expected.
It's not a matter of lack of will, but rather of technical complexity. Scaling industrial processes to millions of units without sacrificing quality is one of the greatest challenges in modern engineering.
Everything suggests that cost parity between electric and combustion engine cars is not as far off as it seemed a few years ago. When that moment arrives, the market will change radically.
The big question is who will lead this transition. The United States and Europe have large companies and expertise, but China has a key advantage: it controls a significant portion of the materials supply chain and is advancing very rapidly in industrialization.
As is so often the case with technology, time will tell. But one thing is certain: the battery revolution is already underway, and when it matures, it will forever change the way we get around.
