Lithium oxygen battery energy storage is a reactive storage mechanism, and the discharge and charge processes are usually called oxygen reduction reaction (ORR) and oxygen evolution reaction (OER). Consequently, complex systems usually create complex problems, lithium oxygen batteries also face many problems, such as excessive accumulation of discharge products (Li2O2) in the cathode pores, resulting in reduced capacity, unstable cycling performance and so on. Cathode catalyst, which could influence the kinetics of OER and ORR in lithium oxygen (Li-O2) battery, is one of the decisive factors to determine the electrochemical performance of the battery, so the design of cathode catalyst is vitally important. This review discusses the catalytic cathode materials, which are divided into four parts, carbon based materials, metals and metal oxides, composite materials and other materials.","PeriodicalId":21005,"journal":{"name":"Research and Application of Materials Science","volume":"16 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80583258","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

With the addition of Si, the reticular white Al-Cu phase deposited were gradually replaced by the gray eutectic Mg-Si phase, while the compressive strength of the alloys increases first and then decreases slowly. It is particularly noteworthy that the compression plasticity also exhibits this trend. When the Si content is 0.9 at.%, the compressive strength reaches its maximum at 779.11 MPa and the compressive plasticity reaches 20.91%.
