CR1220 battery

　　Inorganic electrolyte technology solves CR1220 battery explosion problem

　　In recent years, lithium-ion batteries, as an energy storage device, have formed a huge emerging industry due to their advantages such as high energy density, long cycle life, and no environmental pollution. There are many types of lithium-ion batteries. The more representative ones are commercial battery systems using lithium manganate, lithium cobalt oxide, lithium iron phosphate, nickel-cobalt-manganese ternary materials, and nickel-cobalt-aluminum ternary materials as positive electrodes. Lithium iron phosphate, in particular, has a wide range of application scenarios because of its relatively long cycle life, relatively good safety, and relatively low cost.

　　Lithium battery safety limits the speed of industry development

　　To sum up, lithium-ion batteries are currently mainly concentrated in three major application areas, one is consumer electronics; the other is new energy electric vehicles; and the third is grid energy storage. In particular, new energy electric vehicles and grid energy storage have created a new market space for lithium-ion batteries.

　　According to statistical analysis by the China Chemical and Physical Power Supply Industry Association, China's CR1220 battery sales revenue reached 172.7 billion yuan in 2018, compared with 158.9 billion yuan in 2017, a year-on-year increase of 8.7%. The output of lithium-ion batteries increased from 100.9 billion watt-hours to 124.2 billion watt-hours, a year-on-year increase of 23.1%. Mainly due to the rapid growth of the new energy vehicle power battery and energy storage battery markets.

　　At present, the requirements for new energy electric vehicles and energy storage applications require safety, high energy density, long life, and low cost, and they require quite mature CR1220 battery technology to achieve industrialization to match the rapid development of these two industries. .

　　However, since the electrolyte of lithium-ion batteries uses flammable organic solvents and corrosive electrolyte salts, the electrolyte easily reacts on the surface of the highly oxidized cathode material during charging to produce flammable gases, which increases the internal pressure and causes the battery to bloat. , leakage and other phenomena, causing corrosion and damage to electrical appliances; during discharge, lithium dendrites are easily formed on the surface of the negative electrode to pierce the separator, causing an internal short circuit in the battery, causing the internal temperature of the battery to rise sharply and causing an explosion. Therefore, safety issues are greatly limited Application areas of lithium-ion batteries.

　　Inorganic electrolyte technology solves the problem of explosion

　　Based on the exploration of battery technology, the non-flammability and high conductivity of inorganic electrolyte attracted the attention of German scientific researchers. In 2009, they broke through the technical difficulty of non-cyclable charge and discharge of inorganic electrolyte batteries and found a way to achieve ultra-long life. And with a stable and recyclable inorganic electrolyte system, the battery has higher durability and is non-flammable, ensuring that the battery is safer. The establishment of Swiss Innolith was based on the invention of this technology.

　　It is understood that traditional lithium batteries can actually only achieve 50%-60% of their theoretical power storage value, while Innolith's lithium batteries with inorganic electrolyte can achieve 80%-90% of their theoretical power storage value; After charging and discharging, the battery with inorganic electrolyte will only form an SEI film on the negative electrode, not on the surface of the positive electrode, and the thickness of the SEI film will not change after it is formed; at the same time, Innolith's battery is a lithium battery, but it does not contain cobalt. . These are the reasons why inorganic electrolyte batteries are safe.

　　Innolith has provided frequency regulation services to the US power grid

　　Innolith's core advantage is its non-flammable inorganic electrolyte technology. In 2010, it took the R&D team at that time ten years to actually apply inorganic electrolytes to batteries and create the product P1 for practical application. From 2011 to 2016, the relevant team continuously conducted charge and discharge tests on P1 in a third-party laboratory in Germany. Its charge and discharge depth ranged from 0 to 100%. After five years of continuous testing, more than 50,000 cycles were recorded. The number of charge and discharge cycles is nearly 10 times higher than that of lithium batteries with organic electrolyte.

　　Today, Innolith's product P1 has provided frequency regulation services in the PJM power grid system in the United States, and was certified by UL (Underwriter Laboratories Inc) in 2017. In the future, as the world transitions from fossil fuels to stored electricity, Innolith's battery technology platform is expected to bring breakthrough results for electric vehicles, energy storage and industrial applications.

　　Innolith is looking for quality partners in China

　　In terms of company positioning, Innolith is a battery technology research and development company. Over the past 20 years, Innoly has invested a lot of money in research and development and made many major breakthroughs in technology. In terms of production, Innolith is cooperating with a German battery equipment manufacturer to design and build product production lines.

　　Innolith entered the Chinese market in 2019 and officially established a branch in Beijing, Innolith Battery Technology (Beijing) Co., Ltd., hoping to find like-minded partners in China. At this stage, Innoly has begun to contact several very powerful Chinese battery equipment manufacturers, hoping to mass-produce products and bring more breakthroughs to the market.

　　In addition, Innolith has already discussed cooperation opportunities with many companies around the world, covering energy, electric vehicles, special applications and navigation. Innolith will commercially use licenses to commercialize technology research and development results and promote more innovative products to the market based on the success of P1.
