What Are Lithium Batteries Made Of – Lithium-ion battery invention from the Netherlands Dutch startup LeydJar has developed an unprecedented lithium-ion battery made from pure silicon anodes, increasing battery capacity by 50%
A Dutch startup company called Leadjaar Technologies (named after the predecessor of the battery, invented in the Netherlands in 1745), has developed a revolutionary battery technology. A converted lithium-ion battery with a pure silicon anode that can increase battery power by up to 50%.
What Are Lithium Batteries Made Of
The new technology can be applied to a wide range of products, including consumer electronics, healthcare, technology, drones, electronic vehicles and energy storage. We spoke to Christian Rudd, CEO of Ledger, to explain this new technology and his future ambitions.
Cathode Studies: New Opportunities In Li Ion Batteries
Larger devices, such as drones, provide better features but also require additional battery capacity. The thorny problem with Li-ion batteries is that the energy density is limited by the graphite. It has reached its theoretical limit. The entire battery industry is looking for a better anode material, and the best candidate is silicon. But the problem is when you use silicon as a battery material, it breaks down due to 300-400% swelling during lithiation. LeydJar Technologies from the Netherlands has found a solution to this problem.
LeydJar has made pure silicon anodes that are porous. Porous silicon acts like a sponge and can absorb silicon swelling, taking maximum advantage of silicon’s double capacity compared to graphite. By inserting a pure silicon anode into an existing lithium-ion battery, the energy density of the battery can be increased by up to 50% in volumetric terms.
Christian Rudd, CEO of LeydJar Technologies, announced: Lithium-ion batteries are here to stay for at least the next 20 years, companies are investing heavily in manufacturing capacity, its products lead to widespread mass production advantages They are used in a number of anodes and with our anode, the energy can be significantly improved. Therefore, Li-ion will outperform any other potential battery chemistry for decades to come. 50% more battery capacity
The increased energy density has two advantages. First, smaller devices can be built with similar battery capacity, which can compromise device security. Second, for equal battery volume, increased power may allow OEMs to take greater advantage of processing power, as Moore’s Law is limited by slow advances in battery performance.

The increased energy density of Li-ion batteries in electric vehicles will lead to longer range, lower cost per mile and the ability to store excess renewable energy in the form of EVs.
We differ from other battery chemistry inventors in three aspects: a) As we are the only pure silicon anode, we have the best opportunity to increase energy density, b) We use a one-step process using a roll to roll production of your anode. PECVD machine, it means we have the possibility to expand and it can be used in existing Li-ion battery plants, c) We provide our clean anode technology to everyone who wants to make Li-ion battery all, and therefore not require large investments to be able to compete with existing battery manufacturers, Christian Rudd continued. Dutch inventor Dr. Wim Soppe
Dr. Wim Soppe is the inventor of a revolutionary technology. Rowing Dutch solar cell researchers at the Dutch research institute Ergy ECN (High Tech Campus Eindhove) were looking for a way to improve thin-film solar panels. Their experiment failed because the silicon material turned out to be too porous, making it unusable for solar cells. But soon, Dr. Wim Soppe realized that other industries needed this porous material. From there, the adventure with batteries began.
LeydJar Technologies will begin implementing its pure anode batteries in consumer electronics. But his plans are much bigger than just increasing smartphone battery life by 4 hours. If their approach is successful, the Dutch are ambitious to enter the market for electronic vehicles and energy storage.
Commit To Recycling Used Batteries On National Battery Day
BMW has already embraced the innovative startup company. Last week LeydJar Technologies won the BMW Startup Challenge competition because their technology can significantly increase the range of electric vehicles, which also means a significantly lower cost per kilometer. BMW sees the momentum of innovation that high-tech startups can bring and invests and develops with WeChat through its BMW-i WeChat fund and BMW Garage. LeydJar Technologies beat 61 other promising companies from 10 countries in the Startup Challenge.

A joint team of researchers from the US Advanced Battery Consortium (USABC) and battery manufacturer A123 Systems have developed a new way to recover certain materials from the cathode. Lithium is used in batteries, which can then be used to make new batteries. In their paper published in the journal Joule, the group claims that the process can be used to produce new batteries that are more efficient than batteries made from newly mined metals.
Currently, very few new batteries are made using recycled materials from old batteries – instead, old, dead batteries go to landfill and new batteries are made with fresh materials. In this new study, researchers have found that it is possible to use at least some of the materials in old batteries to make new batteries. They have developed a recycling system that can remove the metals used in lithium battery cathodes, particularly the metals nickel, manganese and cobalt.
The technique starts with draining the battery. The batteries are then cut into pieces and sent through a screen where the case material, wires, plastic and other parts of the battery are removed. The resulting mixture consists of cathode material, other metals and some graphite. These materials are separated by both filtration and leaching. The output is in the form of nickel, manganese and cobalt powder. The researchers note that the powder could be used to make new cathodes for new batteries. They also note that under the microscope, the powder particles had larger pores than metals taken directly from the mine, and were also less brittle. They note that more porous metals make for better batteries because they allow for better ion diffusion. They are also less likely to crack after repeated charging and discharging.

The researchers also built their batteries using recycled materials and tested them using protocols developed by the USABC. They found that they performed as well as or better than batteries made from virgin metals. Also, some of the team members have formed a startup called Battery Resources and have already started selling their recycled materials. They have plans by the end of next year to build a capacity that will be able to process 10,000 tons of batteries per year.
