How to Calculate Battery Charge Time


Battery charge time is determined by dividing the battery capacity by the charging current, adjusted for efficiency. Whether it’s the robust lead acid battery used in vehicles or the sleek LifePo4 battery in modern electronics, this fundamental principle remains consistent. As renewable energy solutions like solar charging become more prevalent, with solar panels efficiently converting sunlight, understanding how to calculate battery charge time is crucial. This article offers a deep …

Moisture and Gas-resistant Packaging for Deformable Batteries in Wearable Devices


At least one in every five people owns a wearable device these days, and for a good reason. Wearable devices are famous for their versatility- they look good and serve various purposes ranging from monitoring biomarkers to serving as vehicles for drug delivery and medical devices. 
However, these devices require stretchy and highly deformable batteries to carry out their functions effectively. As a result, a lot of research has gone into improving the flexibility of batteries while preserving battery life as well as other desirable features, but information on …

Gravity and Water Batteries and Everything in Between


Australia’s desire to become four-fifths powered by renewables has created a need for renewable energy alternatives. While solar and wind sources are getting the job done, there is a need to bridge the gap, prevent intermittency, and create energy for overnight storage. And this is where pumped-hydro comes in. 
Pumped hydro basically consists of two strategically positioned dams – one on a hill and another in a valley- …

The Use of Unwanted Heat from Data Centres in District Heating


The Cool-Data project reports that it is now possible to use flexibility and waste from data centres in Denmark. In this article, we will highlight some questions answered by DTU’s researchers on the utilisation of energy in district heating. 
A research team from DTU, four companies, and a utility work together on the Cool-Data project to develop and implement a new cooling and storage system modified for small and moderate-sized data centres (about 500 servers). 
The European Union desires that data centres …

Can the Power of Lightning be Harnessed?


Lightning strikes about a hundred times per second which amounts to 8.6 million strikes per day. For every strike, one billion joules of electrostatic energy is released- enough energy to 3000 kettles of water. How amazing is that? 
The sun, wind, and water have been successfully harnessed and converted into useful sources of energy. Can scientists perhaps do the same for …
