Beyond Lithium-Ion: How Solid-State Batteries Are Redefining Energy Storage and What It Means for the Future The energy storage landscape is on the brink of a revolutionary shift. Recent headlines in the tech and automotive industries have been dominated by breakthroughs in solid-state battery technology. Unlike conventional lithium-ion batteries that use liquid electrolytes, solid-state batteries employ solid electrolytes, promising unprecedented energy density, enhanced safety, faster charging, and longer lifespan. Major players like Toyota, QuantumScape, Solid Power, and Samsung SDI are in an intense race to overcome the final technical hurdles—primarily related to scalability and cost—with several aiming for limited commercial deployment in electric vehicles by 2025-2027. Industry consensus suggests that widespread (batch market application) for consumer electronics and premium EVs is likely within this decade, though mass-market adoption may take longer.

Power batteries and energy storage batteries are currently the two major applications of battery technology. Energy storage batteries correspond to solar energy and other equipment, and power batteries correspond to new energy vehicles. The battery technology companies once led by Japanese and Korean companies have long ago classified the types of power battery packaging into three major forms: cylindrical, square, and soft. Intuitively, they only differ in shape, but at the same time they There are also differences in technology development and application perspectives, so what kind of difference will happen to small batteries due to different shapes? This is the main content of our issue.   Japan's SONY company invented the 18650 lithium battery in 1992, which has become the most common cylindrical battery design at present. For example, the No. 5 and No. 7 alkaline batteries are designed in this shape. In the following time, due to the increase in battery application scenarios, prismatic batteries led by Samsung SDI and soft pack battery designs led by LG Huawei have also entered the market. At present, the three types of technologies are also applied in new energy vehicle products. For new energy vehicles, the current market structure of the three types of batteries is relatively stable. There is no best but better. Different countries and different car companies have different recognition of the three types of battery technology. I participated in a technical training on soft pack batteries not long ago, so I also want to talk to you in today's content, and feedback to our practical application level, what is the difference between these three types of batteries with different shapes.   Change the standard without changing the cost, and the basic principle must be followed in any change of shape Because of the different manufacturing and packaging methods, the three types of batteries have obvious differences in shape. But there is no impact on the working principle of the battery itself. The manufacturing method is mainly aimed at different working conditions, equipment applications and more diversified examples, which is not very rigorous, like a cake made into different shapes. , But the principle of baking and fermentation of raw materials is the same. Simply put, lithium ions in the electrolyte complete a discharge from the negative electrode to the positive electrode, and then return from the positive electrode to the negative electrode to complete a charge. Therefore, the design of the three different shapes of the battery will comply with the technical principles of the battery itself, but due to the different shapes, the manufacturing and molding are divided into two different processes: winding and stacking.   Cylindrical battery All three shapes of batteries will eventually become cylindrical, square and soft-packed batteries through cylindrical winding, square winding and square stacking. But at present, only cylindrical batteries have consistency in manufacturing standards. For example, the well-known cylindrical batteries are divided into 14650, 18650, 21700 and other models. Many people think that this is a battery type, but it only represents a cylindrical battery. The size standard of the battery. Take the 18650 type as an example. It is currently the most mature cylindrical battery standard. Through continuous technological advancement, the 21700 type is likely to replace the 18650 type as the first-choice cylindrical battery product for new energy vehicles.   Square battery The plasticity of the prismatic battery will be stronger, and the design can be customized according to the specific needs of the product. As a result, there are differences in size. At present, regardless of the manufacturing process or application standards, there is no clear standard division as for cylindrical batteries. But because of its high flexibility, it has been used for a long time in the early new energy vehicles. Car companies can customize the size of the square battery according to the needs of the model, without being restricted by the cylindrical battery standard. The prismatic battery was once considered to be the most suitable battery design for new energy vehicle applications. At present, square batteries are used in many models, such as BMW's i-series models, Roewe ERX5, Weilai's ES8, and the range-extended SUV for cars and homes that will be launched in the future.   Soft pack battery The soft pack battery adopts a superimposed manufacturing method, so it pursues a slimmer volume and the lightest weight under the same capacity density. Similarly, soft pack batteries can also be customized according to application requirements, as small as the size of our mobile phone batteries, as large as used in new energy vehicles. Soft pack batteries have always been the industry’s first choice for mobile devices, but in automotive applications, they are also valued by car brands because of their volume controllability, especially for plug-in hybrid vehicles, taking into account the layout and layout of the entire vehicle. In terms of weight, the volume advantage of the soft pack battery is more obvious. At present, GM’s Buick’s VELITE5/VELITE5, Cadillac’s CT6 plug-in, XT5 hybrid models, and Nissan’s Sylphy battery all use soft pack batteries.   For those in the industry looking for a reliable Lithium Polymer Battery provider, welcome to check out AUKPOWER.

Lithium Polymer (LiPo) batteries, much like chameleons in the world of technology, store significant energy and adapt flexibly to various sizes and shapes. Similar to how chameleons adjust their colors and textures to their surroundings, LiPo batteries change shape based on electronic device design requirements, merging smoothly into portable electronics and providing robust, adaptable power.   Advantages of lithium polymer batteries Lithium polymer batteries are key to contemporary electronics due to their high energy density, light weight and shape adaptability. These batteries can be made in almost any size and shape, suitable for a range of devices from ultra-thin smartphones and wearables to large drones and specialized electronics.   The secret to LiPo batteries’ ability to store large amounts of electricity in a small volume lies in the lithium compounds they use. This lithium compound is like the heart of the battery, lightweight yet full of energy, making the battery both lightweight and efficient. The electrode design of these batteries is also optimized to store more lithium ions, acting like a cleverly designed warehouse to maximize storage space.   In addition, their low internal resistance means almost no energy is wasted during use, like a smooth highway, ensuring that energy flows quickly and efficiently. These features combine to make LiPo batteries ideal for being small, efficient, and energy-dense.   They provide stable power, low self-discharge and longer service life, which are critical for high-energy applications. Additionally, their lighter weight compared to other lithium batteries is crucial to enhance device portability and reduce overall weight, making lithium polymer batteries a valuable energy solution for everyday and professional use.   HUNAN AUK NEW ENERGY CO.,LTD(AUKPOWER) offer customization for specific energy density, shape, size or output needs. This ensures the batteries can meet different customer specifications and requirements, highlighting the value of lithium polymer (Lipo)batteries in diverse and specialized applications. AUK Battery is popular by customers in our country and abroad, any inquiry needs for Lipo Battery welcome contact with us at ay time.
