This will effectively improve the smoothness of the deposited Li film and limit dendrite growth.Īppropriate selections of the electrolyte solvents can further increase the Coulombic efficiency of Li metal deposition/stripping and enable long-term cycling of the Li metal electrode. During the charging process, the positively charged Li ions will be prevented from deposition in the protruded region of the anode by the SHES effect and will instead be preferentially deposited in the non-protruded region. Using the materials and methods claimed in the pending patents, a positively charged self-healing electrostatic shield (SHES) can be formed that covers the protruded region formed during electrodeposition. The electrolytes used in the system are also designed to maintain high Coulombic efficiency. These methods include processing techniques and electrolytes for electrodeposition that result in self-healing, instead of self-amplification, of protuberant tips, which create roughness and/or dendrite formation. One of the most significant barriers to practical use of lithium metal batteries for energy storage has been uncontrollable dendrite lithium growth upon repeated charge/discharge cycling, which degrades battery performance and increases safety risks. PNNL scientists have developed novel materials and processing methods that substantially reduce such growth.
