Emission of gas at charged states of lithium ion batteries (LIBs) is a significant problem because it causes swelling and deformation of LIBs. In this study, the gas generation mechanism is investigated and preventative measures are developed. Decomposition of the electrolyte solution related to residual lithium compounds on the surface of LiNi0.5Co0.2Mn0.3O2 (NCM523) and to the structural change in the cathode active material is investigated as two main mechanisms of gas generation in LIB cells. NCM523 particles are encapsulated in a continuous lithium lanthanum titanium oxide (LLTO) thin layer to inhibit gas-generating reactions. The LLTO layer fixes free lithium of the cathode surface and effectively suppresses side reactions between the charged cathode active material and the electrolyte solution, resulting in substantial reduction of the gas generation. In addition, LLTO-coated NCM523 shows improved capacity retention without any loss of capacity or rate performance because LLTO is a good conductor of Li ions.

This journal publishes original, cutting-edge research in physical chemistry, chemical physics and biophysical chemistry. To be suitable for publication in PCCP, articles must include significant innovation and/or insight into physical chemistry; this is the most important criterion that reviewers and Editors will judge against when evaluating submissions. The journal has a broad scope and welcomes contributions spanning experiment, theory, computation and data science. Topical coverage includes spectroscopy, dynamics, kinetics, statistical mechanics, thermodynamics, electrochemistry, catalysis, surface science, quantum mechanics, quantum computing and machine learning. Interdisciplinary research areas such as polymers and soft matter, materials, nanoscience, energy, surfaces/interfaces, and biophysical chemistry are welcomed if they demonstrate significant innovation and/or insight into physical chemistry. Joined experimental/theoretical studies are particularly appreciated when complementary and based on up-to-date approaches.
