Abstract: This paper presents the comparison between two balancing methods: Active balancing using a Buck-Boost Converter and Passive Balancing by resistance switching. The active balancer was ...

Kristi Noem, the homeland security secretary, said officers had not used pepper spray and similar measures limited by a judge’s order, then was confronted with a video that showed chemical agents ...

It may be possible to extend the life of lithium-ion batteries using standard, low-cost chemistry. Lithium-ion batteries consist of a negative anode and a positive cathode with a porous separator ...

Despite their widespread use, many aspects of lithium-ion battery design have been based on trial and error, with a limited understanding of the underlying physical and chemical processes. A recent ...

Researchers now have a clearer picture of the chemical mechanisms underlying lithium-ion batteries—and it could lead to faster, more efficient batteries for electric vehicles, portable electronics, ...

Abstract: This paper explains the active cell balancing using Buck-Boost converter. The usage of petrol is main cause of greenhouse gasses and global warming, which are serious problems for all life ...

Humans have been making metal alloys for thousands of years, and most of us can conjure a rough mental image of the process—it involves red-hot molten metals being mixed, poured, and shaped in a ...

White analytical chemistry (WAC) integrates environmental, analytical, and practical considerations, surpassing green analytical chemistry (GAC) in scope. The RGB model evaluates methods on ...
