![]() Researchers at the University of California Riverside are working on battery technology that uses sand in order to create pure silicon to achieve three times better performance than current graphite-based lithium-ion batteries. The company is currently working with Mercedes-Benz to develop the technology. ![]() IBM says these batteries will be cheaper to make, can charge faster, and pack in higher energy density and power. The materials are extracted from seawater. IBM Research has discovered a new battery chemistry that is free of heavy metals and can out-perform lithium-ion batteries. Best of all, the sourcing of this silicone is earth friendly as it is made from barley husk ash. The goal is that this will improve battery performance. They hope to replace graphite as the anode and replace it with silicon, which has ten times the capacity. Looking for a cure to unstable silicon in lithium-ion batteries, researchers at the University of Eastern Finland have developed a method to produce a hybrid anode that uses mesoporous silicon microparticles and carbon nanotubes. They claim to have a higher energy density, resulting in a vehicle range of up to an estimated 500 miles on a single charge. The team at U of T say their batteries produce a more elegant distribution of ions as well.Ī Chinese company called SVOLT is manufacturing cobalt-free batteries for the EV market. The motivation is that cobalt is rare, expensive, and harmful to source. Instead, it uses up to 89 percent nickel as well as aluminum and manganese. The University of Texas is working on a lithium-ion battery that doesn’t use cobalt as a cathode. ![]() This technology could be in production as soon as 2023. NAWA says that charging time will be just five minutes to get to an 80 percent charge. ![]() It can also increase energy storage by a factor of three and increase the lifecycle of a battery five times over. This utilizes a vertically-aligned carbon nanotube that can boost battery power ten times over current battery packs. NAWA Technologies has designed and patented an Ultra Fast Carbon Electrode that could change batteries as we know them. Using carbon fiber as the negative electrode while the positive is a lithium iron phosphate, these batteries would be extremely stiff and rigid for structural components. This could lead to lighter vehicles in which body parts are the batteries. Research at Chalmers University of Technology has been focusing on using new battery tech as a structural component of future electric cars. ![]()
