E-waste is short for electronic waste. That is, trash generated from broken, obsolete, and surplus electronic devices. You will also hear people refer to it as e-scraps. E-waste recycling is one of the most talked-about issues in the world today due to its potentials to reduce environmental hazards and pollution

Technological advances are coming at us at such a dizzying speed that a lot of electronic devices that still work fine are the ones considered obsolete.
modern electronics are safe to use and be around. However, most electronics contain some form of toxic materials
That toxic water under the landfill doesn’t stop below the landfill. It continues to the groundwater and the sources to all the freshwater in the surrounding area.
A lithium-ion or Li-ion battery is a type of rechargeable battery which uses the reversible reduction of lithium ions to store energy. The cathode (negative electrode) of a conventional lithium-ion cell is typically graphite made from carbon. The anode (positive electrode) is typically a metal oxide.
Generally, the negative electrode of a conventional lithium-ion cell is graphite made from carbon. The positive electrode is typically a metal oxide. The electrolyte is a lithium salt in an organic solvent.[9] The anode (negative electrode) and cathode (positive electrode) are prevented from shorting by a separato
Lithium-ion is the most popular rechargeable battery chemistry used today. Lithium-ion batteries power the devices we use every day, like our mobile phones and electric vehicles. Lithium-ion batteries consist of single or multiple lithium-ion cells, along with a protective circuit board. They are referred to as batteries once the cell, or cells, are installed inside a device with the protective circuit board.
In a lithium-ion battery, lithium ions (Li+) move between the cathode and anode internally. Electrons move in the opposite direction in the external circuit. This migration is the reason the battery powers the device—because it creates the electrical current. While the battery is discharging, the anode releases lithium ions to the cathode, generating a flow of electrons that helps to power the relevant device.
Electrodes: The positively and negatively charged ends of a cell. Attached to the current collectors Anode: The negative electrode Cathode: The positive electrode Electrolyte: A liquid or gel that conducts electricity Current collectors: Conductive foils at each electrode of the battery that are connected to the terminals of the cell. The cell terminals transmit the electric current between the battery, the device and the energy source that powers the battery Separator: A porous polymeric film that separates the electrodes while enabling the exchange of lithium ions from one side to the other
