Herein, we develop a modified PBI (mPBI) polymer (Scheme 1) as a binder and a separator functional reagent for Li–S batteries. As a binder, the as-prepared mPBI polymer provides resilient adhesion and ...

However, there are many challenges to be addressed before practical applications of lithium-sulfur batteries can be achieved. These challenges include the “shuttle effect” of the intermediate lithium ...

Rechargeable lithium-ion batteries are the power behind most modern portable electronics, including cell phones, tablets, laptops, fitness trackers, and smart watches. However, their energy density — ...

A team led by Cheong Ying Chan Professor of Engineering and Environment Prof. ZHAO Tianshou, Chair Professor of Mechanical and Aerospace Engineering and Director of HKUST Energy Institute, has ...

Researchers have demonstrated a new polysulfide entrapping strategy that greatly improves the cycle stability of Li-S batteries, a new report outlines. Rechargeable lithium-ion batteries are the power ...

Researchers at Shantou University and the Beijing Institute of Technology have developed a new nickel-based foam aimed at alleviating the shuttle effect, volume expansion, and other issues plaguing ...

Lithium sulphur cells can retain >95% Coulomb efficiency for 80 charge cycles at >300Wh/kg, according to the Hong Kong University of Science and Technology, which is working on a novel cathode design.

(Nanowerk Spotlight) Lithium-sulfur (Li-S) batteries, which employ sulfur as cathode and metallic lithium as anode materials, are emerging as promising alternatives to the widely used lithium-ion ...

Lithium-sulfur batteries are a promising addition to lithium-ion batteries due to their high energy density and potentially low cost. However, they suffer from capacity fade over multiple ...

America’s growing demand for electric vehicles (EVs) has shed light on the significant challenge of sustainably sourcing the battery technology necessary for the broad shift to renewable electric and ...

The name "lithium-ion battery" seems to imply that lithium is the essential ingredient that dictates the battery's performance characteristics. But that's less true than it appears. The electrodes ...
