Mercedes-Benz is developing a battery of the future. Recently, foreign media reported that Mercedes-Benz is currently developing degradable organic batteries, and Mercedes-Benz is trying to apply them to future road vehicles. However, it will take at least 15 years for this battery to be mass-produced and applied.
What material is this degradable organic battery made of? Andrias Hintner, senior manager in charge of battery research at Mercedes-Benz (Andreas? Professor Hinntenach) describes the battery. "It's a bit like a fuel cell. It uses graphene as raw material, contains aqueous electrolyte and does not contain any rare metals or toxic substances. " It is reported that early experiments show that degradable organic batteries can significantly improve energy density and fast charging ability.
In fact, this battery technology was launched at CES in Las Vegas, USA in June of this year at 65438+ 10. Released in 2020. The Mercedes-Benz Vision of Avatar Elements? AVTR concept car adopts organic battery technology for the first time. The battery capacity of the car is about 1 10kWh, and the cruising range is over 700 kilometers, which can be fully charged in 15 minutes.
In addition to degradable organic batteries, the current power battery technology can be roughly divided into conventional lithium batteries, solid-state batteries, hydrogen fuel batteries, lithium-sulfur batteries, aluminum-air batteries and so on. Lithium ferrous phosphate and ternary lithium batteries have been widely used, but the shortcomings such as short cruising range and lack of recycling system are equally prominent.
Aluminum-air battery generates electricity through the chemical reaction between oxygen and aluminum, which can solve the battery life and charging problems in one fell swoop. The biggest advantage of lithium-sulfur battery is its ultra-high energy density, but it is full of uncertainty like aluminum-air battery. Solid-state lithium batteries are the light of hope for the new energy industry, which can greatly improve the cruising range and safety. The technical maturity is higher than that of aluminum-air and lithium-sulfur batteries, but not as good as that of fuel cells. ?
Mercedes-Benz is trying to improve the efficiency of lithium-ion batteries. Andreas, senior manager of Mercedes-Benz battery research? Hintennach estimates that while evaluating a series of future technologies, the battery life of lithium-ion batteries still has the potential to increase by 25%, and the company plans to adopt some technologies, including solid-state batteries, in the next 5- 15 years. However, in some cases, it will be better to achieve the same cruising range by reducing the battery weight. Solid-state batteries can be said to have opened a window in the future. Hinnentach said: "Solid-state batteries have added many positive factors. This technology is not a miracle, but it will be a huge progress. "
