Nickel-Cadmium Era: Thomas Edison and Waldemar Jungner contributed to nickel-cadmium batteries, early alternatives for electric vehicles
The quest for efficient electric vehicle batteries began long before lithium-ion dominated the market. In the late 19th and early 20th centuries, nickel-cadmium (NiCd) batteries emerged as a promising alternative, thanks to the pioneering work of Thomas Edison and Waldemar Jungner. Edison, already a household name for his inventions, patented a nickel-iron battery in 1901, while Jungner independently developed the nickel-cadmium variant in 1899. These innovations laid the groundwork for rechargeable batteries that could power early electric vehicles, offering a glimpse into a future less dependent on fossil fuels.
Edison’s nickel-iron battery, though heavier and less energy-dense than Jungner’s nickel-cadmium design, was prized for its durability and longevity. It could withstand thousands of charge cycles, a critical feature for vehicles that required frequent recharging. However, its bulkiness and lower efficiency limited its practicality in automobiles. Jungner’s nickel-cadmium battery, on the other hand, boasted higher energy density and better performance in cold temperatures, making it more suitable for electric vehicles. Despite these advantages, NiCd batteries faced challenges like cadmium toxicity and memory effect, which hindered their widespread adoption.
The nickel-cadmium era marked a transitional phase in electric vehicle battery technology. While neither Edison’s nor Jungner’s designs became the ultimate solution, they demonstrated the potential of rechargeable batteries for transportation. NiCd batteries found their niche in aerospace and portable electronics, but their impact on electric vehicles was limited by emerging alternatives like lead-acid and, later, lithium-ion. Still, their development underscored the importance of innovation in overcoming the technical barriers of early electric mobility.
For modern enthusiasts or historians exploring this era, understanding the trade-offs of NiCd batteries offers valuable insights. Edison’s focus on durability versus Jungner’s emphasis on energy density highlights the perennial tension in battery design: balancing performance with practicality.

Lithium-Ion Revolution: John Goodenough, Rachid Yazami, and Akira Yoshino invented lithium-ion batteries, the EV industry standard
The lithium-ion battery, a cornerstone of the electric vehicle (EV) industry, owes its existence to the groundbreaking work of three scientists: John Goodenough, Rachid Yazami, and Akira Yoshino. Their collaborative efforts, spanning decades and continents, transformed a theoretical concept into a practical energy storage solution that powers millions of EVs today. This revolution began in the 1970s, during the oil crisis, when the need for alternative energy sources spurred innovation in battery technology.
John Goodenough, often referred to as the "father of the lithium-ion battery," made a pivotal discovery in 1980 while at the University of Oxford. He identified lithium cobalt oxide (LiCoO₂) as a stable and efficient cathode material, capable of storing large amounts of energy. This breakthrough was critical because it addressed the instability issues of earlier lithium batteries, making them safer and more reliable. Goodenough’s work laid the foundation for high-energy-density batteries, a prerequisite for their use in EVs. However, his discovery was just the first step; it required further refinement to become commercially viable.
Rachid Yazami, a Moroccan-born scientist working at the French National Centre for Scientific Research (CNRS), contributed the next essential piece of the puzzle. In the early 1980s, Yazami developed the graphite anode, a key component that allowed lithium ions to be efficiently stored and released during charging and discharging cycles. His innovation not only improved the battery’s performance but also extended its lifespan, making it practical for repeated use. Yazami’s graphite anode remains the industry standard today, a testament to its enduring significance.
Akira Yoshino, a Japanese chemist at Asahi Kasei Corporation, brought these elements together to create the first commercially viable lithium-ion battery in 1985. Yoshino combined Goodenough’s cathode and Yazami’s anode with a polypropylene separator, ensuring safety and stability. His design eliminated the use of metallic lithium, which was prone to short-circuiting, and instead relied on lithium ions moving between the cathode and anode. This innovation made lithium-ion batteries lightweight, rechargeable, and safe enough for consumer electronics and, eventually, electric vehicles.
The impact of Goodenough, Yazami, and Yoshino’s work cannot be overstated. Their lithium-ion batteries have become the EV industry standard due to their high energy density, long cycle life, and relatively low maintenance requirements. For instance, modern EVs like the Tesla Model 3 and Nissan Leaf rely on lithium-ion batteries to achieve ranges of over 300 miles on a single charge. These batteries also play a crucial role in reducing greenhouse gas emissions, as EVs produce zero tailpipe emissions compared to internal combustion engine vehicles.
Practical considerations for EV owners highlight the importance of these innovations. To maximize battery life, drivers should avoid frequent full charges and discharges, instead keeping the battery level between 20% and 80%. Additionally, parking in shaded areas or using thermal management systems can prevent overheating, which degrades battery performance. While lithium-ion batteries have transformed the EV industry, ongoing research aims to address challenges like resource scarcity (e.g., cobalt) and recycling, ensuring their sustainability for future generations. The lithium-ion revolution, sparked by Goodenough, Yazami, and Yoshino, continues to drive the transition to cleaner, more efficient transportation.
