to work. Batteries are also needed for cell phones, laptops, hearing aids and wheelchairs.
What is a battery?
A battery slowly converts chemicals packed inside it into electrical energy. It produces electrical energy whenever it is needed.
 Electricity flows without wires.

Batteries power a lot of the things that we use every day, they are an essential part of the components of any device, and as we know there are many different types of batteries and each type has its own role, but the basic concept in which they work is the same.

 A battery is a device that converts the chemical energy in its active materials into electrical energy through electrochemical oxidation and reflux reactions. This type of reaction involves the transfer of electrons from one substance to another through an electrical circuit.

 In a battery, the cell is the actual electrochemical unit used to generate or store electrical energy, meaning a battery is cells connected to each other in series or in parallel, depending on the voltage and the required output capacity Batteries are divided into several types according to the type of metals used such as lead-acid batteries and nickel batteries  Cadmium and nickel iron batteries.  Today, the most common and widely used batteries are lead-acid batteries. This type of battery is mainly divided into two parts, which are dry batteries and liquid batteries.]]> 2021-03-21 02:05:29 UTC https://padlet.com/banihaniebthal1_1/hch3nuullzi4tuoh/wish/1333388728 https://padlet.com/banihaniebthal1_1/hch3nuullzi4tuoh/wish/1333938911 Batteries power a lot of the things that we use every day , they are an essential part of the components of any device , and as we know there are many different types of batteries and each type has its own role but the basic concept in which they work is .the same

Battery:
A battery is a device consisting of one or more electrochemical cells with external connections
 [1] To operate electrical appliances, electric vehicles, cars and electric cars. When the battery supplies electrical power, it is the positive terminal, the terminal and the negative terminal.
 [2] The terminal marked as negative is the source of electrons that will flow through an external circuit to the positive terminal. When a battery is connected to an external electrical load, oxidation and reduction reactants are high-energy energy products, and free energy is delivered to the external circuit.
[3] The history of the brand, aside, the designation "battery" specifically refers to a multi-cell atmosphere, but the use has evolved to include single-cell bodies.]]> 2021-03-21 13:24:10 UTC https://padlet.com/banihaniebthal1_1/hch3nuullzi4tuoh/wish/1334407448 https://padlet.com/banihaniebthal1_1/hch3nuullzi4tuoh/wish/1334409959 9th A🌼💜]]> 2021-03-21 13:25:16 UTC https://padlet.com/banihaniebthal1_1/hch3nuullzi4tuoh/wish/1334409959 https://padlet.com/banihaniebthal1_1/hch3nuullzi4tuoh/wish/1334580762 سيرين عبد الله الزغول

Battery identification
It is a group of one or more cells that undergo chemical reactions to create a flow of electrons within the circuit.

Types of batteries
Batteries are classified into two categories:
A- Batteries that cannot be charged (primary):
They are disposable batteries only and cannot be charged again.
This type of batteries achieved an advance of approximately 23.6% of the global market until 2009, but it began to decline due to the presence of secondary batteries that can be charged.

Primary batteries
Primary battery usage

They are widely used in watches, remote control devices, electronic switches, some lighting devices, and military equipment ... etc.

Primary battery features

No leakage when emptied.
cheap.
It can be navigated.
It can be stored for many years.

Types of batteries Batteries can be classified depending on their electrical characteristics into two main types, namely: Primary batteries: Primary batteries are single-use batteries only and cannot be recharged, including: Alkaline batteries: Alkaline Batterie Alkaline batteries are one of the most common batteries in the world. Its energy density is high, and its service life is long. The alkaline battery consists of two electrodes: a negative electrode consisting of zinc, and a positive electrode consisting of manganese dioxide, and the alkaline battery is called this name because it contains alkaline electrolytes composed of potassium hydroxide, and this battery is used in remote control devices, digital cameras, and watches, Radios, and music players are available in (AA, C, D) sizes.Zinc-Carbon Batteries The dry battery consists of a zinc tray that represents the cathode, and a carbon rod that represents the anode. This rod is surrounded by a mixture of carbon powder and manganese oxide to improve the conductivity of electricity, and the electrolyte is a mixture of ammonium chloride and zinc chloride. The voltage of a zinc-carbon battery is approximately 1.5 volts, and this type of battery is characterized by durability, long life span, and cheap price, but it does not work well at low temperatures. Dry batteries are used to power games, watches, flash lights, and remote controls, and are available in sizes (AAA, AA, C, D). Mercury Batteries The mercury battery is made of mercury oxide and manganese dioxide, and generates a voltage of no less than 1.35 voltsIt is worth noting that mercury batteries are less popular because they contain toxic mercury and have low electric current production. Silver oxide batteries consist of silver oxide that acts as the positive electrode, zinc that acts as the negative electrode, and the electrolyte, which is usually potassium hydroxide or sodium hydroxide, and silver oxide batteries are distinguished by that they are available in different sizes, but they are expensive, and they are suitable for operating electrical devices that need Low electric current]]> 2021-03-22 12:58:57 UTC https://padlet.com/banihaniebthal1_1/hch3nuullzi4tuoh/wish/1337633919 https://padlet.com/banihaniebthal1_1/hch3nuullzi4tuoh/wish/1337821371 ريحان محمد الصمادي تاسع أ]]> 2021-03-22 13:31:52 UTC https://padlet.com/banihaniebthal1_1/hch3nuullzi4tuoh/wish/1337821371 https://padlet.com/banihaniebthal1_1/hch3nuullzi4tuoh/wish/1337986530 ريحان محمد الصمادي تاسع أ😍✌🏼]]> 2021-03-22 13:59:02 UTC https://padlet.com/banihaniebthal1_1/hch3nuullzi4tuoh/wish/1337986530 https://padlet.com/banihaniebthal1_1/hch3nuullzi4tuoh/wish/1339087965 بيلسان محمود عبد الصمادي A battery is a device consisting of one or more electrochemical cells with external connections to power electrical devices such as light bulbs, cell phones, and electric cars.  ... batteries contain much less specific energy (energy per unit mass) than common fuels such as gasoline.
