Monolayer lnP3 as a reversible anode material for ultrafast charging lithium- and sodium-ion batteries: A theoretical study

J. Mater. Chem. A, 2018, Accepted ManuscriptDOI: 10.1039/C7TA10248H, PaperJin Liu, Chun-sheng Liu, Xiao-Juan Ye, Xiaohong YanImproving the battery capacity usually induces the large volume expansion of the electrode, leading to poor reversibility and safety of the battery. Therefore, the high specific capacity, fast…

Will Fire of Apple’s Battery-Gate Spread to Samsung Electronics?

Burden 0r Opportunity for Samsung?The fire of Apple’s Battery-Gate spread to Samsung Electronics. Consumers’ complaints about Apple are leading each government to generally check the smartphone industry and market. Apple aroused controversy as the iPhone’s performance withers when its battery aged. In Korea,…

Microscale Lithium Metal Stored inside Cellular Graphene Scaffold toward Advanced Metallic Lithium Anodes

Abstract The volume expansion and dendrite growth of metallic Li anode during charge/discharge processes hinder its practical application in energy storage. Seeking an appropriate host for distributing bulk Li in a 3D manner is an effective way to solve these problems. Here, a…

NixSy Nanowalls/Nitrogen-Doped Graphene Foam Is an Efficient Trifunctional Catalyst for Unassisted Artificial Photosynthesis

Abstract Solar-to-hydrogen (STH) conversion through unassisted artificial photosynthesis (APS) devices is one of the promising and environmentally friendly strategies for sustainable development. However, the practical large-scale application of the unassisted APS devices is impeded by the need for expensive noble metal-based catalysts in…

Tailoring Sodium Anodes for Stable Sodium–Oxygen Batteries

Abstract Sodium–oxygen batteries based on abundant sodium resource have caused increasing interest due to their high energy density and low cost. However, the reactive sodium anode always induces unpredictable side reactions especially in oxygen atmosphere and battery short circuit due to the uncontrolled…

Lifespan of fuel cells maximized using small amount of metals

Fuel cells are a key future energy technology emerging as eco-friendly and renewable energy sources. In particular, solid oxide fuel cells composed of ceramic materials can directly convert fuels such as biomass, LNG, and LPG to electric energy. KAIST researchers have described a…
