What Is Lithium Ion?
Lithium-ion refers to a type of rechargeable battery technology that utilizes lithium ions as a key component of its electrochemistry. These batteries are a cornerstone of modern portable electronics and are increasingly vital for large-scale energy storage systems and electric vehicles. Within the broader context of sustainable investing, lithium-ion technology represents a significant area of investment and technological advancement, driving innovation across various sectors aiming for reduced carbon emissions. The performance characteristics of lithium-ion batteries, such as high energy density and rechargeability, have made them indispensable for the ongoing global energy transition.
History and Origin
The development of the lithium-ion battery spans several decades, involving critical contributions from multiple scientists. In the 1970s, M. Stanley Whittingham conducted pioneering work on rechargeable lithium batteries using titanium disulfide as a cathode and metallic lithium as an anode. John B. Goodenough later advanced the technology in 1980 by identifying lithium cobalt oxide as a more stable and higher-voltage cathode material. Building on these foundations, Akira Yoshino developed the first commercially viable lithium-ion battery in 1985, replacing the volatile metallic lithium anode with a carbon-based material, petroleum coke, which could intercalate lithium ions more safely. This innovation made the batteries much safer for practical applications. For their groundbreaking work, John B. Goodenough, M. Stanley Whittingham, and Akira Yoshino were jointly awarded the 2019 Nobel Prize in Chemistry for "the development of lithium-ion batteries."18, 19, 20, 21

Lithium Ion vs. Electric Vehicle Battery
While "lithium ion" refers to the specific electrochemical battery chemistry, "electric vehicle battery" describes the application of such a battery within an electric vehicle. All electric vehicle batteries are currently a type of lithium-ion battery, but not all lithium-ion batteries are electric vehicle batteries.
The distinction lies in scope and scale. A lithium-ion cell is a fundamental unit, capable of being used in a small electronic device. An electric vehicle battery, conversely, is a complex system comprising numerous lithium-ion cells, integrated with battery management systems, thermal management, and safety features. These large battery packs are engineered to meet the specific power, range, and durability demands of transportation, distinguishing them from the smaller, less complex lithium-ion batteries found in consumer gadgets. The rapid expansion of electric vehicles is the primary driver of the massive increase in demand for lithium-ion technology.
##5 FAQs
What are the main advantages of lithium-ion batteries?
Lithium-ion batteries offer high energy density, meaning they can store a significant amount of energy for their size and weight. They also have a long cycle life, allowing for many charge and discharge cycles before degradation, and a low self-discharge rate, meaning they retain their charge for longer when not in use. This makes them ideal for portable electronics and electric vehicles.
Why is lithium a "critical mineral" for the energy transition?
Lithium is considered a critical mineral because it is an essential component of lithium-ion batteries, which are foundational to energy storage and electric vehicles. The projected surge in demand for these technologies means a corresponding increase in the need for lithium, making its secure and sustainable supply vital for the global transition to cleaner energy.
##3, 4# What happens to lithium-ion batteries at the end of their life?
At the end of their useful life, lithium-ion batteries should be properly recycled or repurposed to recover valuable raw materials and mitigate environmental risks. They are generally considered hazardous waste if discarded due to potential ignitability or reactivity. Specialized recycling facilities aim to extract materials like lithium, cobalt, and nickel for use in new batteries or other products, supporting a circular economy.1, 2
