A lithium-ion or Li-ion battery is a type of rechargeable battery that uses the reversible intercalation of Li + ions into electronically conducting solids to store energy. In comparison with other commercial rechargeable batteries, Li-ion batteries are characterized by higher specific energy, higher energy density, higher energy efficiency, a longer cycle life, and a longer calendar life.
Small rechargeable batteries can power portable electronic devices, power tools, appliances, and so on. Heavy-duty batteries power electric vehicles, ranging from scooters to locomotives and ships. They are used in distributed electricity generation and in stand-alone power systems.
Under certain conditions, some battery chemistries are at risk of thermal runaway, leading to cell rupture or combustion.As thermal runaway is determined not only by cell chemistry but also cell size, cell design and charge, only the worst-case values are reflected here.
Up until the mid-1990s, Ni–Cd batteries had an overwhelming majority of the market share for rechargeable batteries in home electronics. At one point, Ni–Cd batteries accounted for 8% of all portable secondary (rechargeable) battery sales in the EU, and in the UK for 9.2% (disposal) and in Switzerland for 1.3% of all portable battery sales.
A 2021 study led by researchers at the University of Wisconsin found that the Renewable Fuel Standard increased corn prices by 30% and those of soybeans and wheat by 20%. These price hikes increased corn cultivation by 8.7% which necessitated additional fertilizer usage that increased rates of nitrous oxide emissions and water pollution.
An alkaline battery (IEC code: L) is a type of primary battery where the electrolyte (most commonly potassium hydroxide) has a pH value above 7. Typically these batteries derive energy from the reaction between zinc metal and manganese dioxide.
Cost-plus pricing is a pricing strategy by which the selling price of a product is determined by adding a specific fixed percentage (a "markup") to the product's unit cost. Essentially, the markup percentage is a method of generating a particular desired rate of return. [1] [2] An alternative pricing method is value-based pricing. [3]
The optional 3.0 L Duratec 30 V6 was thoroughly updated, resulting in a 40 hp (30 kW) increase, bringing power output to 240 hp (180 kW) and 223 lb⋅ft (302 N⋅m) of torque. The Duratec 30 also sees a 1 mpg ‑US (240 L/100 km; 1.2 mpg ‑imp) fuel economy improvement. Another significant change was the switch to Ford's new 6F35 6-speed ...
