, Choi Mira, reports in the Pulse, a South Korean publication that the South Koreas leading Lithium ion battery maker announced Friday that engineers at the company and University of California, San Diego jointed, developed a new type of silicon, all solid state battery that uses both a solid state electrolyte and an all silicon anode.. The company said the researchers demonstrated a technology that can develop a battery that delivers 500 charge and discharge cycles, with 80 percent capacity retention at room temperatures. For the first time in the world.. The new work is described in the journal of Science. Silicon anodes can offer 10 times higher energy density than the graphite anodes, mostly used in todays commercial lithium ion batteries., But they degrade with liquid electrolytes. So the existing solid state batteries have relied on metallic lithium. As an anode which restricts the batteries to be charged at 60 degrees Celsius or higher., In order to overcome the limitations, the researchers used micro, silicon and eliminated the carbon and the binders., The team also replaced liquid electrolyte with a sulfide based, solid electrolyte, which is extremely Stable in batteries with all silicon anodes., In addition, the micro silicon, is less processed and less expensive than the nano silicon that is more often used.. Lg Energy Solution said the new work has brought them much closer to realizing all solid state battery techniques. LG Energy Solution is delighted that the latest research on battery technology with UC San Diego made it onto the journal of Science.
A meaningful acknowledgement said Kim Myung hwan. President and chief procurement officer at LG Energy Solution. As a leading battery manufacturer LG Energy Solution, will continue its effort to foster state of the art techniques in leading research of next generation battery cells. He added. Enabling reliable long, lasting energy storage for off grid applications. Lithium ion battery technology has truly changed our world.. Even with these advancements, however, there is potential to improve the lithium ion battery. One advancement that could once again change the way we store energy is the development of the solid state battery. Lets dive into this unique design and learn more. What Is A Solid State Battery Before we learn what a solid state battery is? We need to understand how current lithium ion technology works. Lithium ion batteries work by letting ionic lithium cross the electrolyte barrier between the batterys, anode and cathode the positive and negative ends.. This electrolyte is a liquid in standard lithium ion batteries., A solid state battery uses a solid electrolyte to regulate the lithium ions instead of a liquid one.. So the main difference between a lithium ion battery and a solid state battery lies within the electrolyte., While lithium ion batteries and most other batteries use a liquid electrolyte solid state batteries use a solid electrolyte., Read on to find out what this matters and what it means For the battery user., How Does A Solid State Battery Work? Every battery has two electrodes an anode negative side and a cathode positive side.
. These two electrodes are made of an electrically conductive material. Between these two electrodes and within them is an electrolyte containing electrically charged particles. Ions., The electrolyte allows lithium ions to travel through it to combine with the anode or cathode, depending on charging or discharging.. This chemical reaction permits the flow of electrical charge between the cathode and anode through a circuit allowing a battery to generate an electric current to power. Your device., So when any device is connected to a battery lets, say a light bulb. For example, a chemical reaction occurs between the anode, cathode and electrolyte, creating a flow of electrical energy to power. The light bulb., A lithium ion battery uses a liquid electrolyte to regulate the flow of current and a solid state battery uses a solid electrolyte., And THIS is the difference that will matter Heres how Benefits of Solid State Batteries AKA Why You Will Want One.. There are multiple benefits to solid state battery technology.. In short, the solid electrolyte used in a solid state battery provides higher energy density longer lifespan and increased safety in a smaller size. Lets take a closer look at how this translates to how a user will benefit from solid state battery technology, Smaller and More Lightweight. Energy density measures. The amount of energy a battery contains proportional to its weight., Solid state batteries are said to be capable of delivering 2.5 times more energy density of current lithium ion tech.. This tremendous increase in solid state batteries, energy density means that they will be far smaller and lighter.
. Higher energy density means that batteries could be much lighter and store. The same amount of energy. Weight is a critical concern for mobile power applications. So this could be a game. Changer. Cars, trucks, RVs boats and airplanes all could benefit from being lighter.. Electric vehicles also have much to gain from this technology, as they could get much more range, with less weight and space in battery storage. Faster Charging, Times., Solid state batteries can work at very high rates of power.. Research suggests that they may be able to recharge 4. 6 times faster than current technologies, safely. Safer Battery Experience. Liquid electrolytes found in lithium ion batteries are extremely volatile and highly flammable.. These electrolytes also mustnt be exposed to air. Solid state batteries, contain no liquid parts and will not have this volatile component.. So, while lithium ion batteries are subject to events like thermal runaway leading to explosion and fire, the solid electrolytes used in solid state batteries are nonflammable and thus present a lower risk of igniting a fire.. While the battery may get hot. There is nothing flammable within it that will catch fire.. The frosting on that cake is that these batteries will require fewer safety systems than lithium ion batteries. Do. Eliminating additional electronics can contribute to smaller, lighter weight battery packages which further enhances solid state batteries. Energy density. These batteries may not even require an external BMS in certain situations. Greatly, simplifying its construction., Much Easier to Manufacture. Working with a volatile liquid that cannot be exposed to air is a huge challenge that could be completely eliminated with solid state battery technology.
. A solid electrolyte could enable much faster production that uses less material and energy. Are Solid. State Batteries Too Good To Be True, Absolutely not. Research is being done around the world with new publications and papers coming out regularly on advancements., With so much to gain from solid state technology. There is significant interest in it from many research firms and companies.. In conclusion, compared with conventional lithium ion battery technology, solid state batteries will be lighter, smaller, more powerful charge faster last longer and be safer..
