Types of Batteries Used for Electric Vehicles

Both lead acid batteries and nickel metal hydride (NiMH) batteries are mature battery technologies. These types of batteries were originally used in early electric vehicles such as General Motor's EV1. However, they are now considered to be obsolete with regards to their uses as the main source of energy storage in BEVs.

Heavy metal poisoning | Genetic and Rare Diseases ...

Heavy metal poisoning refers to when excessive exposure to a heavy metal affects the normal function of the body. Examples of heavy metals that can cause toxicity include lead, mercury, arsenic, cadmium, and chromium. Exposure may occur through the diet, from medications, from the environment, or in the course of work or play. Heavy metals can enter the body through the skin, or …

General principles of extraction of metals

these metals can be obtained by the thermal decomposition of their oxide ores. 4. The oxide of a metal which is above another metal in the Ellingham diagram can be reduced by the latter. Thus, Mg can reduce Cr 2 O 3; Al can reduce Fe 2 O 3. For such a reduction, the free-energy change [metal(m1) oxide + metal(m2) → metal(m1) + metal(m2)oxide ...

Ultimate tensile strength - Wikipedia

Ultimate tensile strength (UTS), often shortened to tensile strength (TS), ultimate strength, or within equations, is the maximum stress that a material can withstand while being stretched or pulled before breaking. In brittle materials the ultimate tensile strength is close to the yield point, whereas in ductile materials the ultimate tensile strength can be higher.

Extraction of Metals | Good Science

Metals with an intermediate reactivity, such as iron and zinc, are chemically extracted from minerals by a process known as carbon reduction. Carbon reduction is a type of redox reaction, where carbon is used to displace a metal from a compound.

Reduction of Metals (Extraction from Ore) - A-Level Chemistry

Reduction of metal halides with metals. In many cases, carbon cannot be used to reduce the metal oxide to the metal as the metal reacts with carbon to form the carbide instead. It is possible to avoid this problem by first converting the ore to the chloride, and then reducing the chloride with a more reactive metal such as magnesium or sodium.
