Open AccessNative lattice strain induced structural earthquake in sodium layered oxide cathodes
High-voltage operation is essential for the energy and power densities of battery cathode materials, but its stabilization remains a universal challenge. To date, the degradation origin has been mostly attribu...

Open AccessSuppressing electrolyte-lithium metal reactivity via Li+-desolvation in uniform nano-porous separator
Lithium reactivity with electrolytes leads to their continuous consumption and dendrite growth, which constitute major obstacles to harnessing the tremendous energy of lithium-metal anode in a reversible manne...

Open AccessIn situ observation of thermal-driven degradation and safety concerns of lithiated graphite anode
Graphite, a robust host for reversible lithium storage, enabled the first commercially viable lithium-ion batteries. However, the thermal degradation pathway and the safety hazards of lithiated graphite remain...

A lithium–oxygen battery based on lithium superoxide
Lithium–oxygen batteries allow oxygen to be reduced at the battery’s cathode when a current is drawn; in present-day batteries, this results in formation of Li2O2, but it is now shown that another high energy den...

Open AccessMulti-step evolution and measurement control of finite-dimensional quantum systems
For finite-dimensional quantum systems, we propose a quantum control scheme based on a multi-step unitary evolution and quantum projective measurements. The objective is to design a control law to steer the sy...
