A Greener Battery Solution in Europe
A project in Europe is working on creating an environmentally friendly and energy-dense battery for electric vehicles. Researchers have developed a unique "super glue" that helps maintain the battery pack’s structure even after damage. The chemistry of the battery includes special cathodes and anodes along with a new type of electrolyte that protects them both.
Tailoring Electric Vehicle Batteries
Electric vehicle batteries come in various sizes and chemistries depending on the vehicle category. While the goals for battery makers remain the same – increased energy density, faster charging, cost-effectiveness, and better safety – the means of achieving these goals continue to evolve. Battery scientists in Europe are exploring the concept of a "self-repairing" pack that is also eco-friendly.
Innovative Chemistry for Improved Performance
The battery developed by Norwegian research organization SINTEF boasts a unique chemistry that sets it apart from traditional lithium-ion packs. The cathode is made of lithium-nickel-manganese oxide, which is cobalt-free and contains less nickel and lithium. This chemistry allows for a higher average voltage, leading to better charging times and performance. The anode, on the other hand, is a silicon-graphite composite that enhances stability and strength.
Introducing the "Super Glue" Technology
One of the key components of this innovative battery design is the use of a "super glue" that repairs minor damage to the cells, similar to a self-sealing car tire. This super glue comes in the form of special binders and separators that hold the battery structure together. The development of the first-generation prototype electrolyte with these materials is complete, with a focus now on second-generation cells, according to SINTEF.
Scaling Up Production
While the development of this technology is promising, the ultimate challenge lies in bringing it to the market at scale. Plans are reportedly in place to scale up production and make this innovative battery technology available for commercial use. Innovation in the lab is one thing, but mass-producing a practical product is a different challenge altogether.
Overcoming Manufacturing Hurdles
Manufacturing is a critical aspect of making innovations in battery technology accessible to the mass market. The ability to produce batteries in high volumes across large surface areas in a uniform manner is the key to success. While there have been many battery chemistry breakthroughs in recent years, bringing them from the lab to real-world applications remains a challenge that the industry continues to work on.
