Batteries & Energy Storage

Franklin coined the term while experimenting with a set of linked Leyden jar capacitors, borrowing the military word for weapons working together. Multiplying holding vessels allowed a stronger charge to be stored and more power delivered on discharge, establishing the naming convention still used.

The Italian physicist stacked copper and zinc plates separated by brine-soaked paper disks, producing a steady current for a considerable length of time. It was the first device to convert chemical energy into sustained electrical power, founding the capability outright.

Wet cells used liquid electrolytes prone to leakage and housed in fragile glass jars, making them unsuitable for portable appliances. Near the end of the nineteenth century the dry cell, using a paste electrolyte, removed that constraint and opened the way to portable battery power.

The Zamboni pile supplies only nanoamps but can run without refurbishment or recharge for extraordinary periods. The Oxford Electric Bell has rung almost continuously since 1840 on what are thought to be its original Zamboni piles.

Volta had believed his cells were an inexhaustible energy source and that electrode corrosion was a mere nuisance. Faraday demonstrated that corrosion was an unavoidable consequence of operation, establishing the electrochemical basis of battery science.

The British chemist's cell used a copper pot of copper sulfate with an unglazed earthenware container of sulfuric acid and a zinc electrode. Unlike earlier batteries with fluctuating voltages, it became an industry standard and was widely adopted to power electrical telegraph networks.

The French physicist's design was the first practical rechargeable battery and remains in production today, still the standard choice for starting petrol and diesel engines.

The French engineer's design, refined soon after into the dry cell, became the basis for the disposable battery that powered household devices for the next century.

The Swedish engineer's alkaline rechargeable cell became the dominant technology for portable power tools and electronics for most of the twentieth century, before lithium-ion displaced it.

Working at Exxon during the oil price shocks, he built a working lithium cell that, despite safety problems, opened the search for the practical lithium chemistries developed over the following decade.

The discovery, made while working in Britain, gave rechargeable lithium batteries the higher voltage and stability needed to move from laboratory curiosity toward a commercial product.

Combining a carbon anode with a cobalt oxide cathode at Asahi Kasei produced the first practical, safe rechargeable lithium battery design, the template still used in most cells today.

The launch, initially for camcorders, turned a laboratory chemistry into a mass-market product and set the trajectory that would eventually lead to lithium-ion dominance in vehicles and grid storage.

The Act banned the sale of mercury-containing batteries and enacted uniform labelling requirements for rechargeable batteries. It also required that rechargeable batteries be easily removable, an early regulatory constraint on battery design.

Developments included USBCELL, allowing an AA cell to be charged through a USB connector, and nanoball batteries with discharge rates around 100 times greater than conventional cells. Smart battery packs added state-of-charge monitors and protection circuits preventing damage on over-discharge.

State subsidies and procurement for electric buses and cars in pilot cities began the industrial policy push that eventually made China the world's largest electric vehicle and battery market.

LiFePO4 cells were shown discharging all their energy into a load in 10 to 20 seconds. The result marked a step change in achievable power density for lithium chemistries.

Carbon footprint declaration and due diligence requirements for batteries sold in the bloc started to take effect, adding compliance costs intended to push manufacturers toward more transparent and lower-carbon supply chains.

Restrictions on licensing certain cathode and processing technology abroad extended a pattern already seen in solar manufacturing, aimed at preserving China's manufacturing lead as other countries tried to build rival battery industries.

Chinese cathode and precursor material producers committed billions of dollars to new Moroccan facilities, using the country's free trade access to position output for European and US markets while easing exposure to tariffs on Chinese-made components.

New gigafactory projects backed by domestic conglomerates moved toward construction and early output under the scheme, part of a broader push to build an advanced chemistry cell manufacturing base and reduce import dependence.

Facing thinner margins on premium nickel-based cells and competition from cheaper Chinese lithium iron phosphate batteries, LG Energy Solution, Samsung SDI and SK On expanded LFP development and leaned more heavily on energy storage system sales.

New tax legislation ended the consumer purchase credit for electric vehicles and tightened other support, though manufacturing credits for domestic battery production continued in a reduced form, and several planned gigafactory projects slowed or paused.

The new chemistry, intended to reduce reliance on lithium and cobalt, targeted lower-cost applications such as small vehicles and stationary storage, with production plans set for the following year.

The world's largest battery maker raised several billion dollars in one of the year's biggest share sales, reinforcing its ability to fund overseas plants even as Western governments pushed to reduce reliance on Chinese cell supply.

A prototype electric-car battery was shown charging from 10 to 80 per cent in five minutes, while a Chinese company claimed its introduced car batteries did so in 10.5 minutes, the fastest available. This compared with Tesla's 15 minutes to half-charge.

The multi-billion dollar project, built around Indonesia's nickel reserves and led by a South Korean-backed consortium, slowed several planned stages as global electric vehicle demand growth undershot earlier forecasts.

Once Europe's best-funded battery start-up, the Swedish cell maker filed for Chapter 11 protection in the United States before its parent entered bankruptcy proceedings at home, a severe setback for European ambitions to build a domestic battery industry.

The agreement will force manufacturers to design all electrical appliances sold in the EU, other than those used predominantly in wet conditions, so that consumers can easily remove and replace the batteries themselves. It imposes a design constraint across the entire European market.

The prize recognised their roles in developing the lithium-ion battery across the 1970s and 1980s, the chemistry that now underpins portable electronics and most electric vehicles.

The press release described work by a team led by the lithium-ion battery inventor on a chemistry promising safer, faster-charging and longer-lasting rechargeable cells. Applications cited included handheld mobile devices, electric cars and stationary energy storage.

The installation could store 129 MWh, making it the largest battery in the world as of that year. It demonstrated the commercial viability of utility-scale battery storage on electricity grids.

The installation covered 2,000 square metres, larger than a football pitch, and weighed 1,300 tonnes. It exemplified the early move to grid-scale battery storage.

Battery demand expanded at roughly 30 per cent a year over the period, reaching 180 GWh in 2018. Growth was driven by electrification of transport and large-scale deployment in electricity grids, supported by decarbonisation initiatives, with demand projected to reach 2600 GWh by 2030.
