AAA – 10440 The AAA and 10440 batteries are the same size, but not the same voltage. AAA batteries in alkaline, lithium or Ni-MH are rated at 1.5 volts, where the 10440 is Li-ion and is 3.7 volts. What does … Continue reading →

Size comparison of alkaline batteries (left to right): C, AA, AAA, N, PP3 (9-volt). An alkaline battery (IEC code: L) is a type of primary battery that derives its energy from the reaction between zinc metal and manganese dioxide. Is … Continue reading →

Calcination is a process in which ore is heated in the absence of air or air might be supplied in limited quantity. Roasting involves heating of ore lower than its melting point in the presence of air or oxygen. Calcination … Continue reading →

Leaching is the loss or extraction of certain materials from a carrier into a liquid (usually, but not always a solvent). and may refer to: Leaching (agriculture), the loss of water-soluble plant nutrients from the soil; or applying a small … Continue reading →

The reason for this is that electric motors are much simpler than internal combustion engines. Therefore, EVs can provide full torque — the force that drives the vehicle forward — from 0 kilometers, resulting in instant acceleration. Why does Tesla … Continue reading →

Among the many claims Tesla has made for the 1020-hp Model S Plaid is that it is capable of 200 mph. That’s a rarefied velocity for any car, but especially so for an EV, as they tend to be limited … Continue reading →

Lifepo4 and Lipo are both lithium chemistries, so technically they are both lithium polymer batteries. The difference is in the type of anodes and cathodes and the metals used inside. The naming conventions don’t always make perfect sense since it’s … Continue reading →

Manganese toxicity can result in a permanent neurological disorder known as manganism with symptoms that include tremors, difficulty walking, and facial muscle spasms. These symptoms are often preceded by other lesser symptoms, including irritability, aggressiveness, and hallucinations. Is manganese harmful … Continue reading →

80Ah means “80 ampere*hours” — approximately, the battery can give 80 amperes * 1 hour, or 160 amperes * 0.5 hours, or 40 amperes * 2 hours. 1800W refers to maximum power — if you draw more than that, the … Continue reading →

In 2020 the price of dysprosium oxide was 260 U.S. dollars per kilogram. There are 17 rare earth elements and although they are fairly abundant in the Earth’s crust, often they occur at sparse intervals are are less economically exploitable. … Continue reading →

White gold is made of a mixture of pure gold and white metals such as nickel, silver and palladium, usually with a rhodium coating. White gold is real but it’s not made entirely of gold. The other metals help to … Continue reading →

A typical iPhone is estimated to house around 0.034g of gold, 0.34g of silver, 0.015g of palladium and less than one-thousandth of a gram of platinum. It also contains the less valuable but still significant aluminium (25g) and copper (around … Continue reading →
