Researchers at Boeing have decreased impedance, or resistance, in lithium-ion batteries by introducing a layer of aluminium oxide between lithium electrodes and a solid non-flammable ceramic electrolyte called garnet. Previously, a high degree of impedance between garnet and electrode materials limited energy flow in batteries of this kind. Aluminium oxide all but eliminates the barrier to energy flow, allowing for efficient charging and discharging of stored energy. The use of solid, non-flammable garnet also removes the liquid component of lithium ion batteries, which can leak and catch fire.
