For the first time, scientists have observed how tiny metal "thorns" called dendrites sprout inside lithium-ion batteries, which can cause the batteries to short-circuit. Their findings, published in ...

Brittle, microscopic structures called dendrites form in lithium-ion batteries and can disrupt battery performance. Unlike bulk lithium, which is pliant and supple, dendrites fracture under stress.

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 problems cold weather presents to EV operations. The role of battery temperature management in improving EV cold weather performance. Existing and emerging methods for determining internal cell ...

Single-cell lithium-ion (Li-ion) chargers are widely used, yet many practical designs rely on highly integrated ICs that conceal their internal operation. The type of Li-ion charger outlined in this ...

When designing, specifying, or purchasing a lithium based rechargeable battery pack, a question that should always come up is cell balancing as it relates to safety and long-life for the battery pack.

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 ...
