Ion Battery

Posted : admin On 1/24/2022


Sodium-ion rechargeable batteries could soon be a cheaper and resource-saving alternative to current lithium-ion cells. Powerful prototypes and groundbreaking findings in basic research make a breakthrough seem imminent.

Electromobility, especially in combination with renewable electricity production, is regarded worldwide as a climate-friendly model for the future. However, a yearslong focus on the use of the rare and expensive metal lithium in rechargeable batteries has slowed down the large-scale electrification of vehicles across the world.

Ion Battery Replacement

A lithium-ion (Li-ion) battery is an advanced battery technology that uses lithium ions as a key component of its electrochemistry. During a discharge cycle, lithium atoms in the anode are ionized and separated from their electrons.

Although electric cars, commercial vehicles and e-bikes are gaining ground, their limited ranges, high prices, a cumbersome charging infrastructure and resource-intensive battery production are delaying a rapid turnaround.

For electric vehicles to come into more widespread use, batteries must become even more powerful, durable, sustainable and cost-effective.

The Ion Battery is an electronic item crafted using the Fabricator. It functions identically to a normal Battery, but holds five times as much Energy, at the cost of taking five times longer to fully charge due to its increased capacity. It is unlocked by collecting the data from the Orange Data Terminal inside the Alien Thermal Plant. Lithium-ion battery technology was introduced more than 25 years ago, and it is reaching its limits. The market requires better and higher performing battery technology for the next generation of use cases.

Sodium instead of lithium

Li-Ion battery packs can be refilled with new cells as long as the SMBus (System Management Bus) Digital Circuit is alive and professionally controlled and treated. So, don't be fooled by the manufacturer's notice. They just want to keep their battery price at a premium. Battery makes Wireless!!! A lithium-ion battery is a type of rechargeable battery that contains lithium. These are a standard battery type for many rechargeable consumer products, including smartphones, tablets, and laptop computers. Lithium-ion batteries power many of the worlds rechargeable electronic devices, and replacement batteries are useful to many consumers to.

The solution could be sodium-ion batteries, whose development has recently made astonishing progress. In the foreseeable future, they could replace the lithium-ion batteries currently used not only in electric vehicles, but also in smartphones and laptops.

The two alkali metals lithium and sodium are chemically very similar. Although sodium does not have the energy density of the comparatively rare lithium, it is widely and cheaply available.

Breakthrough in sight

Currently, however, the performance of sodium-ion batteries lags behind that of lithium-ion batteries by about 20 years. For decades, research has been concentrated solely on the more powerful lithium.

Now however, there are not only groundbreaking scientific publications, but also very promising prototypes.


A South Korean sodium-ion battery managed to handle about 500 complete charging cycles before its capacity dropped to 80%, according to a May 2020 publication.

A battery with a slightly different chemical structure devised by a US-Chinese research group achieved 450 charge cycles with a similar charging capacity. And a Chinese sodium-ion battery had a slightly lower capacity, but still retained 70% of its capacity after 1,200 cycles of quick 12-minute charging.

All this may not sound like much, but in practice these batteries would probably survive many more charge cycles, because in everyday life batteries tend to be only partially charged and discharged. The complete loading and unloading of a battery in an experiment puts much more strain on the cell.

In addition, sodium-ion technology does not consume any scarce resources. The production of the cathodes does not require rare lithium salts; simple table salt is sufficient. Powerful anodes can be produced from lignite, wood and other biomass. Cobalt or similar rare substances are also not required.

Multilayer solution

However, sodium has two disadvantages. For one, it is three times heavier than lithium, so sodium-ion batteries are also heavier, even though lithium accounts for less than 5% of the total weight of a battery.

In addition, sodium batteries are less powerful because they inevitably lose around 10% of their energy density due to a 0.3-volt lower cell voltage. This is largely owing to the fact that the graphite anodes that have been used up to now in batteries absorb too little sodium.

Research power

But nanoscale carbon could provide a remedy. This is shown in a study by a German-Russian working group led by the Helmholtz Centre Dresden-Rossendorf (HZDR). The study suggests that double layers of graphene, i.e., wafer-thin carbon, could store significantly more sodium atoms in the anode than the graphite used so far.

If graphene electrodes were to be incorporated into lithium batteries instead of the graphite anodes commonly used today, it might be possible to achieve significantly higher storage capacities.

'It's like putting small balls between two sheets of paper,' explains HZDR physicist Dr. Arkady Krasheninnikov. 'If you stuff more and more balls in, the sheets of paper are pushed apart, leaving more space between them.'

Possible new momentum

If multilayer storage works for lithium, could it also work for other alkali metals such as sodium?

The research group from Dresden, Stuttgart and Moscow looked into this question using complex supercomputer simulations. And their calculations have shown that sodium, like lithium, can be deposited between the graphene sheets not only as a single layer, but in several layers one on top of the other.

So if graphene electrodes were to be installed in sodium-ion batteries in the future instead of the graphite anodes commonly used today, it might also be possible to achieve a significantly higher storage capacity.

Multiple inclusions of sodium between two graphene layers are possible

These results could be a breakthrough for the development of future anodes for low-cost sodium batteries. 'Our work is of a purely theoretical nature, and we do not claim that a new generation of batteries will be developed in the foreseeable future on the basis of our results,' Krasheninnikov emphasizes. 'But perhaps our findings will give engineers some new and interesting ideas.'

Batteries of the future

So, fortunately, sodium-ion batteries are no longer just a theoretical concept. A breakthrough seems imminent that will see them become practical reality.

The latest research results show that there are already tangible, affordable and resource-saving alternatives to the expensive lithium-ion batteries and that their performance can possibly be significantly increased by multilayer storage.

It will certainly take some time before sodium-ion batteries reach a stage of technical maturity and can be produced in large quantities and installed in electric vehicles or mobile phones. But when that does happen, the changeover from lithium- to sodium-ion batteries should be largely unproblematic due to the fairly similar technology involved.

    Old-school biking

    Until recently, the classic old bicycle would have been an obvious option for anyone wanting to get active outdoors. These days, however, there are a number of electric alternatives that require slightly less exertion. But e-bikes and e-scooters aren't always as eco-friendly as you might think, and can cause other problems too.

    The electro-classic

    The e-bike, an enhanced bicycle if you will, is probably the best-known electric alternative to regular bikes. The battery motor makes it move faster and is especially helpful on inclines. One problem: Because it makes biking less exhausting, more seniors who would normally not head out into the traffic anymore, ride e-bikes. That has lead to an increase in accidents.

    The battery problem

    Another issue with e-bikes is the battery, the production of which requires a lot of natural resources. E-bikes run on rechargeable lithium batteries. Digging this metal out of the earth is no easy feat and requires large lithium mines. It's also a finite resource. In 2018, the world's remaining lithium reserves were estimated at 53.8 million tons.

    Growing energy demand

    Electric modes of transportation don't emit CO2, but e-bike batteries have to be charged regularly. The same is true, of course, for batteries of e-scooters, e-skateboards monowheels, hoverboards, … See a trend there? The demand for electricity is growing and not all of it is met with energy from renewable sources.

    Many new ideas — and many more batteries

    As companies keep coming up with cool new e-gadgets for us to buy, the number of batteries that need to be charged is likely to keep rising. In addition to regular e-bikes, there are even e-unicycles. Not into peddling? Then how about a hoverboard, inspired by cult classic 'Back to the Future II'?

    Last mile scooters

    E-scooters are similar to the scooters you might remember from your childhood. These new ones, however, don't rely exclusively on our feet to propel them forward, but on battery power. That makes them more eco-friendly than vehicles with a combustion engine, but many people only use them to travel the 'last mile' from a bus stop or car park to wherever they're going.

    Illegal fun

    Up until now, zipping along the streets on an e-scooter was illegal in Germany. Because of their little 'engine,' you'd need certain permits for e-scooters (like a license for a car), but those weren't available. Starting in the summer of 2019, Germans will be allowed to drive e-scooters with a maximum speed of up to 20 kph (12 mph) on bike paths. In the US, that's been legal for a while.
