Solid-state lithium microbattery technology is poised to leapfrog Li-ion and Li-poly alternatives for hearable and wearable devices. By Arvind Kamath, Ensurge Micropower The more popular digital health and fitness wearables and hearables become, the more frustrating the shortcomings of their rechargeable microbatteries. Decades-old Lithium-Ion (Li-ion) technology has reached its limits while handcuffing product developers to…

Lithium-ion batteries (LIBs) are complex electrochemical and mechanical systems subject to dozens of international safety standards. In this FAQ, we’ll discuss the key environmental aspects of LIB safety, review the top five LIB safety standards, and consider using custom-battery testing rooms for the safety of testing personnel. Many of the LIBs’ safety concerns are because…

The speed at which a battery can be recharged is measured using the “C-rate,” where “C” is the battery’s capacity in mA or A. At a 1 C rate, a battery can be completely recharged in one hour. The speed of charge primarily depends on the voltage. For example: For small batteries used in portable…

Varta will present its broad product portfolio of microbatteries, which make a wide range of future-proof applications possible, at Computex in Taipei starting today. Varta’s microbattery product portfolio ranges from rechargeable lithium-ion button cells to nickel metal hydride button cells, primary silver oxide cells, primary lithium button cells and cylindrical lithium batteries to hydrogen gas…

Researchers at the Georgia Institute of Technology and Korea University have developed a glucose-powered biofuel cell that uses electrodes from cotton that could potentially power implantable medical devices. The fuel cell has twice as much power as traditional biofuel cells and could also be paired with batteries or super capacitors to create a hybrid power…
