A Brief History of Battery Development

Batteries have come a long way since their invention in the early 19th century. The first primitive battery, known as the voltaic pile, was invented in 1800 by Italian physicist Alessandro Volta and consisted of alternating disks of zinc and copper separated by cardboard or cloth soaked in brine or acid. While crude, it provided scientists with a reliable source of electricity and paved the way for further advancements. Throughout the 1800s, batteries slowly improved as scientists experimented with different materials but their uses remained limited. It wasn't until the late 1880s that batteries began powering practical devices like flashlights, doorbells, and telegraphs.

Advances in Battery Chemistry

The true boom in Battery technology occurred in the 20th century as new chemistries were developed. In the 1950s, lithium batteries were first explored but high reactivity issues prevented commercialization. Instead, lead-acid batteries became dominant, powering cars, trucks, and heavy machinery. In the 1960s, research shifted to lithium ion chemistry which showed greater promise. Significant development occurred in the 1970s and 1980s, led by scientists like John Goodenough and Akira Yoshino. They helped improve safety and capacity, leading to the first commercial lithium-ion batteries in 1991 from Sony. Today, over 99% of portable electronics use lithium-ion variants due to their high energy density.

New Applications Drive Demand

Rapid expansion in consumer electronics greatly increased battery usage through the 1990s and 2000s. Simultaneously, electric vehicles and grid-scale storage were gaining attention due to environmental concerns. Both applications require even more powerful batteries to compete with gasoline and fossil fuel alternatives. As a result, battery research intensified with new materials like lithium-sulfur and solid-state being explored. Major manufacturing plants were also constructed to supply the ballooning consumer market and pave the way for electric vehicles. By 2019, the global battery industry was valued at over $90 billion USD. Experts predict it will exceed $130 billion by 2025 as grid storage and EVs take off.

Rise of the Grid-Scale Battery

With renewable energy sources like solar and wind on the rise, managing intermittent supply has become crucial. Here grid-scale batteries play an important role by absorbing excess power and discharging it when renewable output drops. This helps stabilize grids with high renewable penetration. Pioneering projects in places like Australia proved the concept and market is rapidly expanding. Major battery projects totaling multiple Gigawatts are now underway worldwide. Lithium-ion remains dominant but alternatives like flow batteries are gaining traction due to their modularity and longer duration. As renewable costs fall below fossils, energy storage will be critical to fully transition the grid and meet climate targets.

Electric Vehicle Revolution

Perhaps no area will transform the battery industry more than electric vehicles. Automakers are now pouring over $300 billion annually into electrifying their fleets to meet tightening emissions rules. Breakthroughs in lithium-ion chemistry have driven down battery costs by over 85% since 2008, accelerating the viability of EVs. Global EV sales exceeded 2 million in 2018 and major analysts predict they will surpass gasoline vehicles within the next decade or two. Along with consumer demand, commitments from governments and companies to phase out gas vehicles will turbocharge battery manufacturing. Industry leaders like Tesla, CATL, LG Chem and Panasonic are responding with giga-factories capable of supplying millions of EV packs per year. As the worldwide auto sector electrifies, batteries will remain at the heart of this mobility revolution.

From powering flashlights to grid-scale energy storage and electric vehicles, battery technology has enabled monumental changes across society and the economy over just a few decades. While lithium-ion dominates today, intense research continues into next-generation chemistries. As costs fall and performance rises, energy storage will transform industries from transportation to utilities. What was once a niche product is now big business, and the battery industry is sure to see even more rapid growth as it powers our transition to renewable energy. With increased manufacturing, battery technology will remain a driving economic force well into the future.
