igneous rocks. Lithium is found in very low concentration in igneous rocks. The largest concentrations of lithium-containing minerals are found in granitic pegmatites. The most important of these minerals are spodumene (Li2O, Al2O3. 4SiO2) and petalite (Li2O, Al2O3. Is lithium … Continue reading →

Most of the station’s oxygen will come from a process called “electrolysis,” which uses electricity from the ISS solar panels to split water into hydrogen gas and oxygen gas. How does the ISS not run out of oxygen? Water, which … Continue reading →

Cold temperatures and their subsequent slowing of the chemical kinetics reactions impact the internal resistance (Ri) of the cell. High drain rates in cold environments will cause a large voltage drop due to the higher battery Ri. Are alkaline batteries … Continue reading →

Tips to lower screen battery drain Use adaptive brightness: This will ensure you get a bright screen when you need it, but you also save battery when high brightness isn’t necessary. Reduce screen refresh rates: Some devices sport screens with … Continue reading →

DOES THE OUTSIDE TEMPERATURE AFFECT BATTERIES? HOW? Yes. If the batteries are too hot (105°F or higher) or too cold (below 40°F), the batteries will not take a full charge. Is it bad to leave power tool batteries in the … Continue reading →

Power banks can range from single charge (3000mAh) to well over (20,000mAh), and most of the latest smartphones have a battery with around 3000mAh. A 10,000mAh power bank should be able to charge the smartphone up to three times and … Continue reading →

It is no secret that automotive battery performance and lifespan are greatly affected by temperature. Most people believe cold weather is what kills the battery, but it is hot weather that shortens the lifespan of the battery. When the battery … Continue reading →

Battery leakage (commonly known as battery acid) is nasty, corrosive stuff – it can burn your skin, contaminate soil, and of course ruin whatever device it has leaked into. For household batteries, this “acid” is actually alkaline – thanks to … Continue reading →

The optical switch could replace the transistor leading to faster and more energy-efficient chips. Moore’s Law is the observation made by Intel co-founder Gordon Moore that originally called for the number of transistors inside a chip to double every year. … Continue reading →
