Once fully developed, it may provide up to two times higher gravimetric energy density than today's most advanced lithium ion technology. However, the development of Li-Obattery has been plagued by many scientific and technological challenges. These include (i) lithium metal anode suffers from ...
Lithium-ion/polymer rechargeable batteries, which have been widely used today, have distinguished properties, but are very delicate and have to be used with extreme care. Improper use of Li-ion batteries will bring about catastrophic consequences. The incidences of burning and explosions of Li-ion...

allowing them to be made smaller and lighter. As a result, lithium-ion batteries are extensively utilized in mobile devices such as smartphones, tablets, and digital cameras, as well as in household storage batteries, automobiles, various types of ships, and aerospace instruments. They are also...
Xia, X. Han, and co-workers demonstrate that the structural integrity of the layered structure of Li2RuO3 cathode is due to large flexible distortion when totally delithiated, with the formation of O22− species facilitated by the presence of lithium ions in the transition metal layer. This...
Over the last two decades, computational methods have made tremendous advances, and today many key properties of lithium-ion batteries can be accurately predicted by first principles calculations. For this reason, computations have become a cornerstone o
Filling of the electrode and the separator with an electrolyte is a crucial step in the lithium ion battery manufacturing process. Incomplete filling negatively impacts electrochemical performance, cycle life, and safety of cells. Here, we apply concepts from the theory of partial wetting to explain...

Coulombic efficiency (CE) has been widely used in battery research as a quantifiable indicator for the reversibility of batteries. While CE helps to predict the lifespan of a lithium-ion battery, the prediction is not necessarily accurate in a rechargeab
While researchers are exploring alternative battery technologies such as sodium-ion batteries and flow batteries that utilize electrochemical cells, these technologies are far from commercialization. "Few people expect any of these lithium-ion alternatives to be available in the next decade," explains Rot...
