Some liquids such as oil or alcohol do not form ions and do not conduct electricity. Vinegar is mostly water with a small amount of acetic acid in it. The acetic acid separates into ions on so that the solution … Continue reading →

High ionic conductivities are usually related to liquid electrolytes. However, high ionic conductivities were found also in solid state in AgI and RbAg4I5 where the Ag+ conductivity can reach 3 × 10−1 S/cm at near room temperature which are comparable … Continue reading →

Graphite is a form of the element carbon, lead is a form of the element, well, lead. If you are asking the writing portion of a pencil, called pencil lead, therein lies a story. Are graphite and lead pencils the … Continue reading →

RTILs are molten salts that are liquid around room temperature (<100°C). They usually contain an organic anion and/or cation with an irregular shape, which keeps them liquid even at low temperatures (Fig. Why are ionic liquids liquid at room temperature? … Continue reading →

Salts that you are most familiar with, like your table salt at home, are solid at room temperature. But some special salts, called ionic liquids are liquid at lower temperatures. The properties of these compounds are unique as far as … Continue reading →

A typical cell has a voltage of 1.5 volts (we write this as 1.5 V). By connecting cells in series, we can makes batteries with 3 V, 6 V and so on. Each battery is labelled with its voltage. How … Continue reading →

Harmonised System (HS) codes are an international standard for calculating Import Duty tax. Controlled by the World Customs Organisation (WCO), the system was first introduced in 1988. Each HS code describes a particular trade product, which allows governments around the … Continue reading →

There are four ways that you’re able to charge your RV’s deep cycle battery: While driving, your alternator will charge your RV battery. When you’re connected to shore power, your converter will trickle charge your RV battery. When you run … Continue reading →

Battery minerals refers to minerals used in rechargeable batteries. This includes lithium, nickel, cobalt, graphite, manganese, alumina, tin, tantalum, magnesium and vanadium. What are batteries made of? The average alkaline AAA, AA, C, D, 9-volt or button-cell battery is made … Continue reading →

Lead is not radioactive, and so does not spontaneously decay into lighter elements. Radioactive elements heavier than lead undergo a series of decays, each time changing from a heavier element to a lighter or more stable one. Once the element … Continue reading →

This may come as a shock to some people but lead pencils do not contain any lead. Never did. The “lead” actually is a mixture of graphite and clay; the more graphite, the softer and darker the point. Is pencil … Continue reading →

The same is true for a trickle charge on an RV battery. This type of charge is perfect for lead acid batteries that are going to be sitting idle for a while. As they sit, they slowly lose their charge. … Continue reading →

A terminal block is a tool used to safely connect two or more wires together. Also known as a terminal block connector, these blocks use a clamping component and conducting strip to secure and organize connecting wires. What is a … Continue reading →

The top manufacturer of electric vehicle is Tesla Motors. Their Model S has the smallest one as 60 kWh and the largest one as 100 kWh battery. The model S also supports 110, 220 and 440 V chargeable voltages. What … Continue reading →
