Have you ever wondered why you have to recharge your smartphone battery at increasingly shorter intervals after 1 to 2 years of use? Of course, the phenomenon is not limited to the battery in the smartphone – every rechargeable battery inevitably loses storage capacity over time. But what is the reason for this? And how

We know lithium batteries mainly from our smartphones, laptops, or smartwatches: all devices that can be recharged again and again once the battery is empty, but not all lithium batteries are rechargeable. Some chemistries, generally CR (lithium manganese dioxide) and ER (lithium thionyl chloride) batteries, may not be recharged under any circumstances. Both types of

Lithium batteries are one of the most widely used types of batteries and serve a variety of applications, including electronic devices and energy storage. We know these batteries mainly from our smartphones, wearables, or cars, which we can recharge time and again. However, there are battery chemistries with lithium that cannot be recharged. These include,

Electroencephalography, or EEG for short, is a methodology for measuring tiny brain signals that are quite difficult to capture. You can likely imagine how these tests look like: Participants have electrodes and lots of cables around their heads while being in a lab. However, these complex systems cannot measure the human brain in the natural

moderne grün schimmernde Batterie

Clattering coins, a line of people, and pattering rain: a run-of-the-mill evening scenario in front of a yellow telephone booth. These previously offered the only opportunity to check in with family or friends while on the go. Nowadays, the 140-year era of the telephone booth has come to an end—the smartphone already sealed its fate

Header: Ein Batteriepack für XSPECTER

Founded in October – and on the market within just six months: Start-up XSPECTER has its T-CROW XRII to thank for this success. The product behind this futuristic name is a special tripod for thermal imaging and night vision cameras. The product: A controllable 3D-printed camera tripod The T-CROW XRII is a controllable camera tripod

header IEC certification

The standards of the International Electrotechnical Commission (IEC) are among the most important groups of standards for the certification and safety of electronic products. They include both cells and batteries and span primary cells, secondary cells, battery packs and portable device batteries. In addition to the requirements for the devices and central rules for the

When developing battery packs, the question arises as to which safety system the pack should be equipped with. Is a Protection Circuit Module (PCM) sufficient? Or should a Battery Management System (BMS) be integrated? What are the differences between the mechanisms? And what advantages and functions does which protection mechanism offer? The answer here, as

Charging Process: Lithium-batteries are charged with constant current until a voltage of 4.2 V is reached at the cells. Next, the voltage is kept constant, and charging continues for a certain time. The charger then switches off further charging either after a preset time or when a minimum current is reached. In the rare event

What special features are there to consider when designing-in a lithium polymer cell? An important point, according to battery expert Dr Jürgen Heydecke, is certainly the so-called “swelling”, the natural swelling of a lithium polymer cell in a fully charged state and over cycles. A fully charged cell is thicker than a discharged one. During
