With the global shift towards electrified transportation, the search for the perfect battery for electric vehicles, one that offers an excellent balance of cost, energy density, safety, and sustainable environmental development, is becoming increasingly important. Currently, there are about ten battery chemistries competing in the market, and which one will come out victorious is a trillion-dollar question. At least for the foreseeable future, traditional lithium batteries will likely continue to dominate the market, while sodium-based batteries offer affordable and environmentally-friendly alternatives for specific applications, according to the latest research conducted by Focus, an AI-powered analysis platform that predicts technological breakthroughs based on global patent data. However, it is graphene and double-ion batteries that seem to have the potential to truly revolutionize the market.
According to the research, graphene batteries, in particular, are expected to enter the market in the early to mid-2030s, as the cost of graphene production decreases, sparking competition with lithium batteries for electric vehicles. This development not only promises significant improvements in the performance of electric vehicles but also contributes to greater energy efficiency and reaching carbon emission reduction goals. “If there is one battery technology to keep an eye on, it’s graphene,” says Jard van Ingen, CEO and co-founder of Focus.
Young contenders
Focus analyzes the current state of battery chemistry for electric vehicles and predicts which ones are likely to dominate in the future. Using a method inspired by the Massachusetts Institute of Technology’s research, the Focus platform processes large amounts of global patent data in real-time, utilizing three types of artificial intelligence: language models continuously research global patent archives to search, evaluate, and compare technologies; vector search provides information about global innovation and the technological landscape in real-time; and multidimensional regression offers predictive analyses, identifying relationships between data and real-world results. Focus calculates “technology readiness levels” for battery technology maturity and “technology improvement index” to measure annual performance growth in dollars for different battery chemistries. “Essentially, it’s about finding a balance between energy density, safety, cost, and sustainable development,” says Kacper Górski, COO of Focus. “Each of these chemistries brings something unique, and their development will shape the future of electromobility. The key question, however, is which ones are developing rapidly and which ones are overhyped?”
Focus found that all lithium battery technologies are improving at a similar pace. Current dominant chemistries, such as lithium-nickel-manganese-cobalt and lithium-iron-phosphate, improve year over year (YoY) at rates of 30% and 36% respectively. Lithium-sulfur batteries improve at a rate of 30% YoY, and silicon anodes at a rate of 32%, indicating that this pair will not disrupt the market – truly innovative technologies have significantly and consistently higher performance growth rates compared to competitors. Similarly, although much has been written about the potential of solid-state lithium-ion batteries, Focus states that this technology only improves at a rate of 31% YoY, which means it won’t disturb the current rivals either.
The same applies to sodium-based batteries, which also received much attention but have an improvement index of 33%, putting them within the margin of error compared to lithium-iron-phosphate batteries. Van Ingen explains that sodium batteries have a relatively modest energy density, which limits the range they can offer electric vehicles without significantly burdening the vehicle. However, sodium batteries can find their niche in energy storage systems where weight is not a limitation. They work well in cheaper mass-produced electric vehicles designed for short distances. “It’s a technology that is developing relatively fast, but it won’t fully revolutionize the market.”
