Solid-state batteries are theoretically safer, more stable, and have higher energy densities than conventional Li-ion batteries with liquid electrolytes. Unfortunately, they also tend to have relatively high resistance at the interfaces between their electrodes and solid electrolytes, which can limit the rate of charging and discharging. In order to solve this, researchers from the Tokyo… Read more »

Carnegie Mellon creates new method to 3D print battery electrodes
Porous electrodes have been 3D printed in the past using extrusion processes in which a strand of material is extruded from a heated nozzle. Interdigitated, or clasped, structures created with this technique provide space for ion flow, but their limited geometries are quite inefficient. Carnegie Mellon University’s new research has developed a completely different additive process… Read more »
Penn State researchers develop cold-weather fast charging method for Li-ion batteries
Fast charging cold Li-ion batteries comea with the risk of lithium plating. When metallic lithium is formed in a battery, it can severely reduce battery lifespan and increase instability. Researchers from Penn State have suggested a solution to that problem that can provide 15-minute fast charging and a twelve-year battery lifespan in temperatures as low as… Read more »

New Johnson Matthey plant will produce samples of eLNO battery material
Johnson Matthey is currently building a demonstration plant with a capacity of 1,000 metric tons to showcase its proprietary eLNO lithium nickel oxide battery material. The plant will be used for R&D and will also produce material samples. The company intends to use the facility to build its market presence and commercialize its eLNOs, which claim… Read more »
Cambridge study reveals fast-charging potential of niobium tungsten oxides
Cambridge research has shed light on the potential of a previously ignored class of electrode material: niobium tungsten oxides. These compounds display several promising properties, including a lack of the dendrite formation which plagues graphite-based designs. They have a relatively large particle size and a structure that allows lithium ions to travel freely. This high transport rate can… Read more »
Honda and Panasonic experiment with battery swapping for electric motorcycles
Honda and Panasonic plan to conduct an experiment with battery swapping in Indonesia, using the Honda Mobile Power Pack with electric motorcycles. The project is to begin in December. As the third-largest motorcycle market in the world, Indonesia is dealing with massive air pollution as traffic increases. To address this issue, the Indonesian government has… Read more »
BYD to complete 24 GWh capacity battery plant
Battery specialist BYD has opened a140 football field-size battery factory in China’s lithium-abundant Qinghai province. The plant is BYD’s third Chinese battery factory, and is part of the company’s plan to increase total production capacity to 60 GWh by 2020. Scheduled for completion in 2019, the plant will be heavily automated, using driverless guided vehicles,… Read more »
Hyundai invests in solid-state battery materials specialist Ionic Materials
Hyundai’s venture capital division, Cradle, is investing in Massachusetts-based battery materials developer Ionic Materials. Ionic says its patented solid polymer material enables solid-state batteries that are inherently safe, high in energy density and operational at room temperature. The special properties of Ionic’s polymer electrolyte also support lithium-ion cells with little to no cobalt in their cathodes…. Read more »
