This convenient 20V MAX* Starter Kit includes a compact battery and charger. Easily operable for quick plug in, the 20V MAX* Starter Kit includes a battery with 2.0Ah capacity optimized for extended power tool use. Instantly check battery state of charge with the 3-LED fuel gauge system on the battery to avoid unplanned work stoppages. Rapidly power up and get right back to work with the included charger that features a multi-function LED indicator to display charging status, when to replace battery pack, and battery temperature. 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.
Li-ion batteries consist of largely four main components: cathode, anode, electrolyte, and separator. A battery is made up of an anode, cathode, separator, electrolyte, and two current collectors (positive and negative). The anode and cathode store the lithium. The electrolyte carries positively charged lithium ions from the anode to the cathode and vice versa through the separator. Lithium batteries provide ample power for most starting situations. A battery is a device that stores chemical energy and converts it to electrical energy. The chemical reactions in a battery involve the flow of electrons from one material (electrode) to another, through an external circuit.
Lithium-ion (Li-ion) batteries are used in many products such as electronics, toys, wireless headphones, handheld power tools, small and large appliances, electric vehicles and electrical energy storage systems. Lithium-Ion batteries are rechargeable and are used in vaping devices, many personal electronics such as cell phones, tablets, and laptops, E-Bikes, electric toothbrushes, tools, hoverboards, scooters, and for solar power backup storage. The movement of the lithium ions creates free electrons in the anode which creates a charge at the positive current collector. The electrical current then flows from the current collector through a device being powered (cell phone, computer, etc.) to the negative current collector.
