Home reading: Li-Ion battery

short circuit

A connection that allows current to take the path of least resistance

hazard

A danger or risk.

Battery

A device that converts chemical energy to electrical energy

smartphone

A device that integrates a cell phone with the features of a PC, such as the ability to store information, receive email, and install programs.

self-discharge

A process in which batteries lose their stored charge without any external connection between their electrodes. This results from internal chemical reactions within the battery.

rate

A ratio that compares two quantities measured in different units

cycle

A series of events that happen over and over again.

constant

A value that does not change

electric vehicle

A vehicle that you plug in to charge a battery. The electrical energy runs the motor.

cordless drill

Battery powered portable drill

aerospace

Branch of technology and industry concerned with aviation and space flight.

Li-ion

Lithium-Ion

Ni-cad

Nickel-Cadium

mass production

Process of making large quantities of a product quickly and cheaply

Load characteristics

Relation between the instantaneous values of a pair of variables such as an electrode voltage and an electrode current

Conductivity

The ability of an object to transfer heat or electricity to another object.

Battery lifespan

The amount of time your battery lasts until it needs to be replaced

Technology

The application of scientific knowledge for practical purposes

recycle

The process of making new products from materials that were used in another product.

Excessive voltage

When the voltage in a circuit or part of it is raised above its upper design limit

lithium ion battery

a battery that produces electrical current in the form of motion of lithium ions from the anode to the cathode

electronic device

exhibit

show, display

time-consuming

taking a long time to do

Monitoring

the act of observing something (and sometimes keeping a record of it)

Priming

the activation, often unconsciously, of particular associations in memory

current density

the amount of current per unit area

energy density

the amount of energy that can be stored in a given system, substance, or region of space.

safety

the condition of being protected from or unlikely to cause danger, risk, or injury.

electric current

the flow of charged particles, usually electrons, around a circuit.

capacity

the maximum amount that something can contain.

maintainance

the process of preserving a condition or situation

integrated
