Electrolyte-assisted low-voltage decomposition of LiCO for efficient cathode pre-lithiation in lithium-ion batteries.

Lithium oxalate (LiCO) is an attractive cathode pre-lithiation additive for lithium-ion batteries (LIBs), but its application is hindered by its high decomposition potential (>4.7 V). Due to the liquid-solid synergistic effect of the NaNO additive and the LiNiCoMnO (NCM) cathode material, the decomposition efficiency of micro-LiCO reaches 100% at a low charge cutoff voltage of 4.

Efficacy of repetitive transcranial magnetic stimulation on chronic migraine: A meta-analysis.

Introduction: Migraine is a neurovascular disorder that affects the quality of life of more than 1 billion people worldwide. Repetitive transcranial magnetic stimulation (rTMS) is a neuromodulation tool that uses pulsed magnetic fields to modulate the cerebral cortex. This meta-analysis ascertained the therapeutic or preventive effect of rTMS on chronic migraine.

Layer-by-Layer Engineered Silicon-Based Sandwich Nanomat as Flexible Anode for Lithium-Ion Batteries.

Lithium-ion batteries with high electrochemical performance and stable mechanical compliance are pivotal to propel the advanced wearable electronics forward. Herein, a high-conductive flexible electrode densified from multilayer lamellar unit cells with the silicon-based sandwich structure is rationally designed by molecular engineering. Silicon nanoparticles can be uniformly anchored to the surface of 2,2,6,6-tetramethylpiperidine-1-oxyl (TEMPO)-oxidized bacterial cellulose (TOBC) aerogel through hydrogen bonding, which effectively relaxes the drastic volume expansion of the Si-based anode.

[The influence of self-improving based group psychotherapy in defense mechanisms for the clients with social anxiety disorder].

Objective: To evaluate the influence and therapeutic effect of self-improving based group psychotherapy which bases on pathopsychology mechanism of social anxiety disorder (SAD) in denfense mechanisms for the client with SAD.

Methods: 70 psychotherapy clients and inpatients with SAD were involved in this group psychotherapy voluntarily. Every group had six to eight clients with SAD and two psychotherapists.
