The Battery Series
Part 1: The Evolution of Battery Technology
The Battery Series is a five-part infographic series that explores what investors need to know about modern battery technology, including raw material supply, demand, and future applications.
Introduction to The Battery Series
Today, how we store energy is just as important as how we create it.
Battery technology already makes electric cars possible, as well as helping us to store emergency power, fly satellites, and use portable electronic devices.
But tomorrow, could you be boarding a battery-powered airplane, or living in a city powered at night by solar energy?
The Battery Series is a five-part infographic series that explores how batteries work, the players in the market, the materials needed to build batteries, and how future battery developments may affect the world. This is Part 1, which looks at the basics of batteries and the history of battery technology.
Batteries convert stored chemical energy directly into electrical energy. Batteries have three main components:
(-) Anode:The negative electrode that gets oxidized, releasing electrons
(+) Cathode: The positive electrode that is reduced, by acquiring electrons
Electrolyte: The medium that provides the ion transport mechanism between the cathode and anode of a cell. It can be liquid or solid.
At the most basic level, batteries are very simple. In fact, a primitive battery can even be made with a copper penny, galvanized nail (zinc), and a lemon or potato.
The Evolution of Battery Technology
While creating a simple battery is quite easy, the challenge is that making a good battery is very difficult. Balancing power, weight, cost, and other factors involves managing many trade-offs, and scientists have worked for hundreds of years to get to today’s level of efficiency.
Here’s a brief history of how batteries have changed over the years:
Voltaic Pile (1799)
Italian physicist Alessandro Volta, in 1799, created the first electrical battery that could provide continuous electrical current to a circuit. The voltaic pile used zinc and copper for electrodes with brine-soaked paper for an electrolyte.
His invention disproved the common theory that electricity could only be created by living beings.
Daniell Cell (1836)
About 40 years later, a British chemist named John Frederic Daniell would create a new cell that would solve the “hydrogen bubble” problem of the Voltaic pile. This previous problem, in which bubbles collected on the bottom of the zinc electrodes, limited the pile’s lifespan and uses.
The Daniell cell, invented in 1836, used a copper pot filled with copper sulfate solution, which was further immersed in an earthenware container filled with sulfuric acid and a zinc electrode.
The Daniell cell’s electrical potential became the basis unit for voltage, equal to one volt.
The lead-acid battery was the first rechargeable battery, invented in 1859 by French physicist Gaston Planté.
Lead-acid batteries excel in two areas: they are very low cost, and they also can supply high surge currents.
This makes them suitable for automobile starter motors even with today’s technology, and it’s part of the reason $44.7 billion of lead-acid batteries were sold globally in 2014.
Nickel Cadmium (1899)
NiCd batteries were invented in 1899 by Waldemar Jungner in Sweden. The first ones were “wet-cells” similar to lead-acid batteries, using a liquid electrolyte.
Nickel Cadmium batteries helped pave the way for modern technology, but they are being used less and less because of cadmium’s toxicity. NiCd batteries lost 80% of their market share in the 1990s to batteries that are more familiar to us today.
Alkaline Batteries (1950s)
Popularized by brands like Duracell and Energizer, alkaline batteries are used in regular household devices from remote controls to flashlights. They are inexpensive and typically non-rechargeable, though they can be made rechargeable by using a specially designed cell.
The modern alkaline battery was invented by Canadian engineer Lewis Urry in the 1950s. Using zinc and manganese oxide in the electrodes, the battery type gets its name from the alkaline electrolyte used: potassium hydroxide.
Over 10 billion alkaline batteries have been made in the world.
Nickel-Metal Hydride (1989)
Similar to the rechargeable NiCd battery, the NiMH formulation uses a hydrogen-absorbing alloy instead of toxic cadmium. This makes it more environmentally safe – and it also helps to increase the energy density.
NiMH batteries are used in power tools, digital cameras, and some other electronic devices. They also were used in early hybrid vehicles such as the Toyota Prius.
The development of the NiMH spanned two decades, and was sponsored by Daimler-Benz and Volkswagen AG. The first commercially available cells were in 1989.
Sony released the first commercial lithium-ion battery in 1991.
Lithium-ion batteries have high energy density and have a number of specific cathode formulations for different applications.
For example, lithium cobalt dioxide (LiCoO2) cathodes are used in laptops and smartphones, while lithium nickel cobalt aluminum oxide (LiNiCoAlO2) cathodes, also known as NCAs, are used in the batteries of vehicles such as the Tesla Model S.
Graphite is a common material for use in the anode, and the electrolyte is most often a type of lithium salt suspended in an organic solvent.
The Rechargeable Battery Spectrum
There are several factors that could affect battery choice, including cost.
However, here are two of the most important factors that determine the fit and use of rechargeable batteries specifically:
Think of specific energy as in the amount of water in a tank. It’s the amount of energy a battery holds in total.
Meanwhile, specific power is the speed at which that water can pour out of the tank. It’s the amount of current a battery can supply for a given use.
And while today the lithium-ion battery is the workhorse for gadgets and electric vehicles – what batteries will be vital to our future? How big is that market?

The World’s Tech Giants, Ranked by Brand Value
Tech giants and e-commerce brands are thriving—and running circles around less pandemic-proof brands.
The World’s Tech Giants, Ranked by Brand Value
The pandemic has businesses everywhere on the ropes, with many firms filing for bankruptcy since lockdowns began. Despite the uncertainty, tech giants and major digital retail brands are still thriving—and some are running circles around those that are less pandemic-proof.
Using data from Kantar and Bloomberg, a recent brand report released by BrandZ shows which tech companies are proving their worth to consumers during COVID-19 chaos. With data covering almost 4 million consumers, BrandZ also reveals that the tech sector leads the world’s 100 most valued brands in terms of financial power and consumer sentiment.
Here’s how the top 20 tech brands from the report stack up:
|Rank||Company||Brand Value (2020)||Change (%)|
|#1||🇺🇸 Apple||$352 billion||+14%|
|#2||🇺🇸 Microsoft||$327 billion||+30%|
|#4||🇨🇳 Tencent||$151 billion||+15%|
|#6||🇺🇸 IBM||$84 billion||-3%|
|#7||🇩🇪 SAP||$58 billion||0%|
|#9||🇺🇸 Accenture||$41 billion||+6%|
|#10||🇺🇸 Intel||$37 billion||+17%|
|#11||🇺🇸 Adobe||$36 billion||+29%|
|#12||🇰🇷 Samsung||$33 billion||+7%|
|#13||🇺🇸 Salesforce||$30 billion||+13%|
|#15||🇨🇳 Huawei||$29 billion||+9%|
|#16||🇺🇸 Oracle||$27 billion||+2%|
|#17||🇺🇸 Cisco||$26 billion||-9%|
|#18||🇺🇸 Dell||$18 billion||-2%|
|#19||🇨🇳 Xiaomi||$17 billion||-16%|
|#20||🇨🇳 Baidu||$15 billion||-29%|
Out of the top five tech brands, Microsoft made the biggest moves with 30% brand value growth. Other big movers in the top 20 were Instagram (owned by Facebook), Adobe, and LinkedIn (owned by Microsoft), rising 47%, 29%, and 31%, respectively.
Broken down by nation, U.S. brands are dominating tech’s heavy hitters, claiming 14 of the world’s top 20 tech brands. Chinese brands round out much of the remaining top 20, including tech entertainment and social media giant Tencent, which rose 15% in brand value since 2019.
Big Tech’s Heavyweights
Tech’s top brands are raking in billions of dollars, capturing consumer mindshare, captivating people, and comforting them during volatile months. Apple, Microsoft, Google, Tencent, and Facebook—tech’s leading contingent—have made those moves look easy during what are rough times for many world brands.
While most tech brands in the upper half of the top 20 saw significant increases in brand value, only Facebook and IBM were in decline from 2019, at -7% and -3% respectively. The biggest loss in tech’s top 20 came from China’s Baidu, which fell by -29% in 2020.
Waning consumer trust, thanks in part to the perceived misuse of personal data, is a gap that tech’s popularity alone won’t fill forever. (Following the Cambridge Analytica scandal, nearly 25% of Facebook account holders reported being “extremely” or “very” concerned about their personal data.)
Coming in at eighth place, Facebook-owned Instagram gained 47% in brand value—a huge percentage, but less than the whopping 95% growth it had in 2019.
On the whole, digital apps have been faring well during the pandemic, especially those built for entertainment, shopping, social connection, and delivery.
These brands had anticipated, even invented, the online-offline dynamics of modern life that became indispensable for survival during the lockdown homebound weeks of avoiding the contagion.
— BrandZ 2020 Global Top 100 Report
Top Brands, by Category
While the brand value growth rates of tech giants aren’t entirely immune to the effects of COVID-19, the likes of Apple, Microsoft, and Google are growing steadily, surpassed only by e-commerce leader Amazon.
With data collected into April 2020, BrandZ’s report on the world’s top 100 brands reflects multiple shifting needs and consumer concerns at a categorical scale.
While consumer affinity for e-commerce and social media brands has increased, fast food and beer brands took a hit, despite reports of increased alcohol consumption and food delivery during lockdown. It would seem then, that consumers have been valuing their tools and means of consumption.
Of the report’s 14 brand categories, only six increased in value, mostly by less than 5%. Of the top risers, six were tech brands and six were mainly e-commerce.
Other upwardly mobile brands were those in the apparel and personal care categories. Much like retail, those categories had an increasing reliance on technology to deliver their products.
The above chart shows overall categorical changes for 2020 led by retail, tech, and insurance. In the opposite corner, energy, and bank brands took the biggest hits.
Rolling with the Punches
The economic impacts of COVID-19 are undeniable. Even still, BrandZ’s top 100 brands marked a steady increase of 6% in value in 2020, compared to 7% the previous year.
This pandemic has offered up era-defining change, with tech and e-commerce seizing the day. But in a climate where nothing can be taken for granted, brands large and small are still taking their knocks.
For now, the brands that are embraced by consumers will be those that can apply a salve to the blows that 2020 keeps delivering.
