Prices of lithium-ion batteries have fallen over time. Overall, between 1991 and 2018, prices for all types of lithium-ion cells (in dollars per kWh) fell approximately 97%. [79] Over the same time period, energy density more than tripled. [79] Efforts to increase energy density contributed significantly to cost reduction. [83]
He also developed the first photocapacitor. [4] [5] [6] Since 2009, Miyasaka has been working on research and development of perovskite solar cell, therefore, he won the Clarivate Citation Laureates in 2017. [7] In 2017 Miyasaka was awarded the Hamakawa award for his contribution in photovoltaic science and technology development. [8]
Polyacetylene had low real density which meant high capacity required large battery volume, and also had problems with instability, so Yoshino switched to carbonaceous material as anode and in 1985 fabricated the first prototype of the LIB and received the basic patent. [9] [14] [15] This was the birth of the current lithium-ion battery. [9]
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 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.

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 ...
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 ...
