Researchers at the Paul Scherrer Institute and ETH Zurich in Switzerland have developed a simple procedure that they say can enhance the performance of Li-ion batteries by improving the design of the electrodes without changing the underlying chemistry. In “Magnetically aligned graphite electrodes for high rate performance Li-ion batteries,” published in Nature Energy, Juliette Billaud… Read more »
