“The combination of 3M’s expertise in battery materials science with Nanoscale’s unique, patented process will help move the battery industry forward,” said Erik Aunan, vice president of 3M Electronics Materials Solutions Division. “Together, we’re looking forward to uncovering solutions that will meet the growing demands of the battery marketplace.”
Nanoscale’s patented process to put extra lithium into the anodes of lithium-ion batteries overcomes many of the obstacles of previous pre-lithiation technologies and has demonstrated scalability for battery manufacturers. This enables cell manufacturers to make batteries that hold more energy in less space and weight by using high capacity anode materials like silicon.
3M silicon anode materials have more than three times the capacity of conventional anode materials and can increase battery energy by up to 40% when matched with high-energy cathodes. The combination of 3M’s silicon alloy and Nanoscale’s pre-lithiation process has proven effective to extend battery life and increase cell energy even further. The companies have demonstrated high performance cells with anodes that hold more than 1200 mAh/g, three times the capacity of state-of-the-art graphite anodes used today.
“We see 3M as an important strategic relationship to commercialize high energy anodes for longer life cells for everyone’s favorite mobile devices, as well as longer range for electric cars,” said Nanoscale CEO Ron Wohl.
3M battery materials include anode powder, current collector and electrolyte technologies, as well as cathode IP technology for license. 3M also makes tapes and adhesives for assembly of battery packs and consumer electronics devices. Using its broad portfolio of battery materials, 3M has the unique capability to integrate these materials to solve customers’ battery problems.
