Lithium-ion batteries power everything from smartphones to electric vehicles today, but safer and better alternatives are on the horizon. . Li-on batteries have a number of drawbacks, which have affected everything from iPhone production to the viability of electric cars. Some of these problems include: 1.. . Let’s start with a battery technology that doesn’t stray too far from the Li-on baseline we’re familiar with. Sodium-ion batteries simply replace lithium ions as charge carriers with sodium. This single change has a big impact on battery production as sodium is far. . A lithium-ion battery uses cobalt at the anode, which has proven difficult to source. Lithium-sulfur (Li-S) batteries could remedy this problem. . Lithium-ion batteries use a liquid electrolyte medium that allows ions to move between electrodes. The electrolyte is typically an organic. [pdf]
Now Alsym Energy has developed a nonflammable, nontoxic alternative to lithium-ion batteries to help renewables like wind and solar bridge the gap in a broader range of sectors. The company’s electrodes use relatively stable, abundant materials, and its electrolyte is primarily water with some nontoxic add-ons.
Emerging alternatives could be cheaper and greener. In Australia's Yarra Valley, new battery technology is helping power the country's residential buildings and commercial ventures – without using lithium. These batteries rely on sodium – an element found in table salt – and they could be another step in the quest for a truly sustainable battery.
In addition, alternative batteries are being developed that reduce reliance on rare earth metals. These include solid-state batteries that replace the Li-Ion battery’s liquid electrolyte with a solid electrolyte, resulting in a more efficient and safer battery.
MIT researchers have now designed a battery material that could offer a more sustainable way to power electric cars. The new lithium-ion battery includes a cathode based on organic materials, instead of cobalt or nickel (another metal often used in lithium-ion batteries).
Yes, lithium-ion batteries contain valuable metals like cobalt and nickel that can be extracted during recycling. However, they need to be properly handled so very little effort goes into recycling them. Lithium-ion batteries power everything from smartphones to electric vehicles today, but safer and better alternatives are on the horizon.
“It is already competitive with incumbent technologies, and it can save a lot of the cost and pain and environmental issues related to mining the metals that currently go into batteries.” Dincă is the senior author of the study, which appears today in the journal ACS Central Science.

Valve-Regulated Lead-Acid (VRLA) batteries are a type of sealed lead-acid battery, which includes Absorbent Glass Mat (AGM) and Gel cell batteries. These batteries are designed with a valve that releases excess. [pdf]
There are three distinct types of lead acid batteries: flooded acid, gelled acid, and Advanced AGM (Absorbed Glass Mat). Any one type can be designed and built for either starting or deep cycle applications. There are various quality levels available in each type.
Flooded lead-acid (FLA) batteries, also known as wet cell batteries, are the most traditional and widely recognized type of lead-acid battery. These batteries consist of lead plates submerged in a liquid electrolyte, typically a dilute sulfuric acid solution. They are commonly found in automotive applications, such as cars, motorcycles, and trucks.
The broad categories are: 1. Flooded Lead-Acid Battery In these battery types, the electrodes that are made of lead and lead oxide are dipped in a dilute solution of sulfuric acid. The sulfuric acid is usually concentrated at 35% sulfuric acid and 65% water.
The rate of corrosion caused by the sulfuric acid on the electrodes is lower in sealed lead acid batteries than in flooded lead-acid batteries. The seal batteries will also experience lower or no terminal corrosion unlike in flooded lead acid batteries where terminal corrosion is a persistent problem.
The oxygen gas is directed to the negative electrode where it reacts with the lead electrode to form lead sulfate and lead oxide while hydrogen forms ions and remains dissolved in the electrolyte. In sealed lead-acid batteries, the electrolyte is held in an absorbent glass mat or as a gel.
Flooded lead-acid batteries must be kept in an upright or verticle position. When the battery is toppled over, the acid will leak through the vents and cause damage as sulfuric acid is very corrosive. Trojan T-1275 is a good example of a flooded lead-acid battery. It has an amperage of around 150Ah. It is good as a starter battery.
