18650 lithium rechargeable battery

　　These three battery technologies may be able to change the world in the future

　　With the development of technology today, our demand for better 18650 lithium rechargeable battery is also increasing. Because although the computing power of devices and the fields of use of devices are constantly expanding, the power supply capabilities of 18650 lithium rechargeable battery have undergone almost no noticeable changes. In recent times, the news media have been reporting endlessly on various new battery technology breakthroughs, but most of these new technologies are difficult to commercialize; as people keep repeating: What happens in the laboratory is It is another thing to find cost-effective production methods for mass production.

　　But the battery race continues: Electric carmakers are looking for cheaper, lighter, more powerful and longer-lasting 18650 lithium rechargeable battery. Electronic device manufacturers are also looking for 18650 lithium rechargeable battery that are more reliable, last longer and charge faster. Manufacturers of wearable and medical implantable devices are more inclined to smaller, longer-lasting battery technology. Renewable energy companies are also looking for battery technology that can stably charge and discharge thousands of times.

　　Among the new battery technologies we hear about all the time, we’ve selected three that have the most practical promise. We analyze how far away these technologies are from practical application and what impact they may have in the future.

　　solid state battery

　　Let’s start with an emerging technology that avoids the dangers of lithium-ion 18650 lithium rechargeable battery. This technology is called solid-state battery technology, and it comes in many forms. To understand why this type of battery is safer, we can first look at why lithium 18650 lithium rechargeable battery are at risk of spontaneous combustion.

　　Most traditional lithium 18650 lithium rechargeable battery have two electrodes (anode and cathode). Between the cathode and anode is a liquid electrolyte that conducts lithium ions. The main problem with lithium 18650 lithium rechargeable battery is that the electrolyte is very flammable. If the lithium battery is damaged or is hit hard, the battery may catch fire, and the following situations may occur:

　　Solid-state 18650 lithium rechargeable battery do not have a liquid electrolyte; they use a layer of other materials to conduct ions and generate energy between two electrodes.

　　Safety is only one aspect of solid-state battery technology. Because there is no liquid electrolyte in solid-state 18650 lithium rechargeable battery, they don't need additional layers of protection, so they can be lighter and smaller. This is great news for automakers. The Advanced Advanced Research Projects Agency for Energy (ARPA-E) of the U.S. Department of Energy has multiple solid-state battery development projects, some of which are developing solid-state lithium-ion 18650 lithium rechargeable battery, and some of which are developing solid-state 18650 lithium rechargeable battery of other materials.

　　The leader in the field of solid-state battery research is Sakti3 Company, whose CEO is AnnMarie Sastry. Kevin Bullis of "MIT Technology Review" described the work done by Sakti3 and Sastry in an article. The company's current focus is how to achieve large-scale production of solid-state lithium 18650 lithium rechargeable battery. The article reads:

　　She is also developing manufacturing technologies that will facilitate mass production. ‘If your overall goal is to change the way people drive, your criteria can’t just be the best energy density and more charge cycles. ’ She said, ‘The primary goal is endurance while providing the necessary performance.

　　Sakti3's work sounds exciting, but the company has been secretive about its technology, so the types of electrolyte materials used in the battery are currently unknown, and of course the types of materials that will be used in large-scale production are unknown. It has a huge impact on costs in manufacturing. But we know that Sakti3 has received venture capital including General Motors, and the company claimed as early as last year that it had achieved twice the energy density of current lithium-ion 18650 lithium rechargeable battery. Another solid-state battery company, QuantumScape, has been much quieter, but there are rumors that the company is also working on similar technology.
