Voltage fade has quietly limited some of the most promising lithium-ion cathodes, eroding the energy they can deliver long ...

Aqueous batteries are much safer than traditional Li-ion cells but generally have a lower energy density. However, a team of researchers in China invented a new water-based battery that is almost ...

Even with current limitations, practical Li–S pouch cells already demonstrate ~700 Wh/kg — almost three times the energy ...

Unico’s 4-channel, 5-V, 300-A advanced battery-cell formation device enables gigafactories to deliver lithium cells with 50% longer life and higher factory throughput. Producing the millions of ...

The proliferation of affordable lithium batteries has made modern life convenient in a way we could only imagine in the 80s when everything was powered by squadrons of AAs, or has it? [Ian Bogost] ...

The EA-BIM 20005 battery impedance meter from Tektronix uses electrochemical impedance spectroscopy (EIS) across 20 channels to characterize Li-Ion battery cells. With industry-standard interfaces and ...

A team has gained new insights into lithium-sulphur pouch cells at the BAMline of BESSY II. A new picture emerges of processes that limit the performance and lifespan of this industrially relevant ...

The ever-changing properties during cell charging. The impact of wire-path resistance. Dealing with charger inefficiencies. When lithium-ion cell testers are being specified, the request is for a ...

While every major power tool brand has its own proprietary battery system to power tools and accessories, the general concept of a rechargeable power tool battery is more or less consistent among them ...

Battery life; we can never have enough of it. Even though most smartphones from the past few years will easily take you through a day of use and possibly even two, the oldies among us still pine for ...
