They do hold 1.5 volts each like a triple A battery but they're slightly shorter, and the diameter is narrower. But if you ever need a AAA they will work with a small piece of aluminum foil.

Water and electronics don't usually mix, but as it turns out, batteries could benefit from some H2O. By replacing the hazardous chemical electrolytes used in commercial batteries with water, scientists have developed a recyclable 'water battery' – and solved key issues with the emerging technology, which could be a safer and greener alternative.

Modern power cells could maintain stability by using ionic bonds to control their electrical charge, but this is illegal as it would result in a salt and battery.

Officials are sounding the alarm about the grave dangers posed by the lithium-ion batteries found in electric vehicles.
Is it any surprise that ferry companies and underground car parks are banning EVs, insurance companies are refusing to insure them, and EV owners are struggling to sell them on the second-hand market?
How long until they are banned outright? 🤔

have you heard about this new, potentially recyclable batteries made using crab shells? it isnt perfected yet, but it could potentially make renewable energy even MORE renewable, because it wont need to be stored in lithium batteries
Hi Shawn! Well this is awesome--thank for sending this in!
Very basic synopsis of the technical bits: Zinc ion batteries have a lot of advantages over lithium ion batteries, but over time the zinc ions produce "dendrites" that significantly reduce the efficiency and longevity of the battery. Researchers tried using a compound found in crustacean exoskeletons to stabilize the zinc, and the result outperformed any existing zinc batteries.
The materials used for zinc batteries are far more sustainable and recyclable than those used in lithium batteries, so if this advance allows zinc batteries to replace some or all uses of lithium batteries that would be a huge win!
"Hu and his team hope their new development can lead to a battery that can be completely degraded or recycled—so that renewable energy sources like solar and wind can produce power that doesn’t require unsustainable processes to store. If the goal is to one day eliminate pollution, this battery is a step (or scuttle) in the right direction."

[In February, 2023], a small warehouse in the English city of Nottingham received the crucial final components for a project that leverages the power of used EV batteries to create a new kind of circular economy.
Inside, city authorities have installed 40 two-way electric vehicle chargers that are connected to solar panels and a pioneering battery energy storage system, which will together power a number of on-site facilities and a fleet of 200 municipal vehicles while simultaneously helping to decarbonize the UK’s electrical grid.
Each day Nottingham will send a combination of solar-generated energy — and whatever is left in the vehicles after the day’s use — from its storage devices into the national grid.  The so-called “vehicle to grid” chargers deliver this energy just when it’s needed most, during peak evening demand, when people are home cooking, using hot water or watching TV. Later, the same chargers pull energy from the grid to recharge the vehicles in the wee hours of the night, when folks are sleeping and electricity is cheaper and plentiful.
“We are trying to create a virtual power station,” says Steve Cornes, Nottingham City Council’s Technical Lead. “The solar power and battery storage will help us operate independently and outside of peak times, making our system more resilient and reducing stress on the national grid. We could even make a profit.” ...
After around a decade, an EV battery no longer provides sufficient performance for car journeys. However, they still can retain up to 80 percent of their original capacity, and with this great remaining power comes great reusability.
“As the batteries degrade, they lose their usefulness for vehicles,” says Matthew Lumsden, chairman of Connected Energy. “But batteries can be used for so many other things, and to not do so results in waste and more mining of natural resources.”
The E-STOR hubs come in the form of 20-foot modular containers, each one packed with 24 repurposed EV batteries from Renault cars. Each hub can provide up to 300kW of power, enough to provide energy to dozens of homes. One study by Lancaster University, commissioned by Connected Energy, calculated that a second life battery system saved 450 tons of CO2 per MWh over its lifetime...
Battery repurposing and recycling is set to play a massive role over the coming years as the automobile industry attempts to decarbonize and the world more broadly attempts to fight waste. The production of EVs, which use lithium-ion batteries, is accelerating. Tesla, for example, is aiming to sell 20 million EVs per year by 2030 — more than 13 times the current level. In turn, 12 million tons of EV batteries could become available for reuse by 2030, according to one estimate.
“Over the next decade we are going to see this gigantic wave,” says Jessica Dunn, a senior analyst at the Union of Concerned Scientists. “Companies are recognizing this is a necessary industry. They need to ramp up infrastructure for recycling and reuse.”

While the lithium-ion batteries in disposable electronic cigarettes are discarded after a single use, they can continue to perform at high capacity for hundreds of cycles, according to a study published December 12 in the journal Joule. The analysis, conducted by scientists from University College London (UCL) and the University of Oxford and supported by The Faraday Institution, highlights a growing environmental threat from these increasingly popular vape pens, which are not designed to be recharged. "The surprise for us were the results that pointed toward just how long these batteries could potentially cycle," says Paul Shearing, Professor of Sustainable Energy Engineering at the Department of Engineering Science at the University of Oxford and UCL. "If you use a low charge and discharge rate, you can see that for over 700 cycles, you still have more than 90% capacity retention. That's a pretty good battery, actually. And these are just being discarded. They're being chucked on the side of the road."
