British chemist M. Stanley Whittingham, then a researcher at ExxonMobil, first reported a charge-discharge cycling with a lithium metal battery (a precursor to modern lithium-ion batteries) in the 1970s. [5] Drawing on previous research from his time at Stanford University, [10] he used a layered titanium(IV) sulfide as cathode and lithium ...
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.
Lithium-ion battery Curve of price and capacity of lithium-ion batteries over time; the price of these batteries declined by 97% in three decades. Lithium is the alkali metal with lowest density and with the greatest electrochemical potential and energy-to-weight ratio.
A solar charger is a charger that employs solar energy to supply electricity to devices or batteries. They are generally portable. Solar chargers can charge lead acid or Ni-Cd battery banks up to 48 V and hundreds of ampere hours (up to 4000 Ah) capacity. Such type of solar charger setups generally use an intelligent charge controller.
He also invented the first rechargeable lithium metal battery (LMB), patented in 1977 and assigned to Exxon for commercialization in small devices and electric vehicles. Whittingham's rechargeable lithium metal battery is based on a LiAl anode and an intercalation-type TiS 2 cathode. His work on lithium batteries laid the foundation for others ...
In 1980, Yazami was the first scientist to establish the reversible intercalation of lithium into graphite in an electrochemical cell using a polymer electrolyte. Eventually, his discovery led to the lithium-graphite anode which is now used in commercial lithium-ion batteries , a product with over $80 billion in market value.
Blue plaque erected by the Royal Society of Chemistry commemorating work towards the rechargeable lithium-ion battery at Oxford The U.S. government eventually terminated Goodenough's research funding, so during the late 1970s and early 1980s, he left the United States and continued his career as head of the Inorganic Chemistry Laboratory at the ...
Fixed mount solar chargers are also known as solar panels. These are often connected to the electrical grid via control and interface circuits, whereas portable solar chargers are used off-grid (i.e. cars, boats, or RVs). Although portable solar chargers obtain energy only from the sun, they can charge in low light like at sunset.
