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.
A properly designed charger can allow batteries to reach their full cycle life. Excess charging current, lengthy overcharging, or cell reversal in a multiple cell pack cause damage to cells and limit the life expectancy of a battery. Most modern cell phones, laptop and tablet computers, and most electric vehicles use lithium-ion batteries. [27]
Lithium nickel manganese cobalt oxides (abbreviated NMC, Li-NMC, LNMC, or NCM) are mixed metal oxides of lithium, nickel, manganese and cobalt with the general formula LiNi x Mn y Co 1-x-y O 2. These materials are commonly used in lithium-ion batteries for mobile devices and electric vehicles, acting as the positively charged cathode.
South Africa's biggest mobile operator Vodacom is looking at taking a new low-price phone that uses the cloud to offer smartphone-style features to other African markets, an executive said on ...
Chemical & Mining Co. of Chile Inc. (NYSE: SQM) or Sociedad Quimica y Minera de Chile SA, has lost its 20-year concession to produce lithium awarded recently through a public tender from the ...
A lithium-titanate battery is a modified lithium-ion battery that uses lithium-titanate nanocrystals, instead of carbon, on the surface of its anode.This gives the anode a surface area of about 100 square meters per gram, compared with 3 square meters per gram for carbon, allowing electrons to enter and leave the anode quickly.
A few companies offer lithium stock ETFs: Amplify Lithium & Battery Technology ETF (BATT): BATT invests in companies that generate significant revenue from the development, production and use of ...
One of the main research efforts in the field of lithium-manganese oxide electrodes for lithium-ion batteries involves developing composite electrodes using structurally integrated layered Li 2 MnO 3, layered LiMnO 2, and spinel LiMn 2 O 4, with a chemical formula of x Li 2 MnO 3 • y Li 1+a Mn 2-a O 4 • z LiMnO 2, where x+y+z=1.
