Lithium grain fine study

Lithium metal negative electrodes are very promising in term of specific energy but suffer from poorly controlled plating and heterogeneity growth. The mechanisms that subtend this heterogeneity formation, nucleation, evolution, and the critical conditions for which it occurs are still not clear. The aim of this session is to validate the preliminary design of cells for deeper comprehension of the grain lithium behaviour during plating experiments.金属锂负极在比能量方面极具应用潜力，但却存在锂沉积难以精准调控、生长不均的问题。支撑这种不均形成、成核与演化过程的机制，以及其发生的临界条件，目前仍未明晰。本次实验环节旨在验证电池的初步设计方案，以更深入地理解锂沉积实验过程中锂晶粒的行为特性。
