A typical 12 V, 40 Ah lead-acid car battery. An automotive battery, or car battery, is a rechargeable battery that is used to start a motor vehicle.. Its main purpose is to provide an electric current to the electric-powered starting motor, which in turn starts the chemically-powered internal combustion engine that actually propels the vehicle.
Many common phenomena can be attributed to autoxidation, such as food going rancid, [2] the 'drying' of varnishes and paints, and the perishing of rubber. [3] It is also an important concept in both industrial chemistry and biology. [4] Autoxidation is therefore a fairly broad term and can encompass examples of photooxygenation and catalytic ...
Lead–acid battery-recycling sites have themselves become a source of lead pollution, and by 1992, the EPA had selected 29 such sites for its Superfund clean-up, with 22 on its National Priority List. [39] An effective pollution control system is a necessity to prevent lead emission.
For example, the fracture surface of a fuel connector showed the progressive growth of the crack from acid attack (Ch) to the final cusp (C) of polymer. In this case the failure was caused by hydrolysis of the polymer by contact with sulfuric acid leaking from a car battery. The degradation reaction is the reverse of the synthesis reaction of ...

An electric vehicle battery is a rechargeable battery used to power the electric motors of a battery electric vehicle (BEV) or hybrid electric vehicle (HEV). They are typically lithium-ion batteries that are designed for high power-to-weight ratio and energy density.

Oxidative stability is a measure of oil or fat resistance to oxidation. Because the process takes place through a chain reaction, the oxidation reaction has a period when it is relatively slow, before it suddenly speeds up. The time for this to happen is called the "induction time", and it is repeatable under identical conditions (temperature ...
A button battery inside a children's book caused a car seat to burst into flames, according to a North Carolina fire department. The George Hildebran Fire & Rescue Department, located in Burke ...
