Battery failure is mainly derived from uncontrollable lithium dendrite formation. This project aims to investigate fundamental lithium dendrite formation mechanism by utilizing a novel in-situ transmission electron microscopy cell. This project expects to build a new set up which is capable of simultaneous in-situ electrical and nanomechanical measurements of lithium dendrite growth. This project aims to reveal how lithium dendrite growth is affected by different surface modifications on the commercial graphite electrodes. The success of the project will lead to a fundamental understanding of the lithium dendrite formation mechanism, enabling the construction of significantly safer batteries.

电池失效的主要原因是无法控制的锂树枝晶形成。本项目旨在利用一种新型的原位电子显微镜来研究锂树枝晶形成的基本机制。该项目希望建立一种新的装置，能够同时进行锂树枝晶生长的原位电学和纳米机械测量。本项目旨在揭示商业石墨电极上不同表面修饰对锂枝晶生长的影响。该项目的成功将使人们对锂树枝晶形成机制有一个基本的了解，从而能够建造出安全得多的电池。
