In today's rapidly developing smart phones, the battery is the "heart" of the mobile phone, and its performance directly determines the battery life and user experience of the mobile phone. With the increasing demand for mobile phone usage time, how to release more surging power in a small space has become the core challenge of battery technology development. Mobile phone battery built-in battery soft pack polymer lithium battery cell, with its high energy density, light and portable advantages, has become the mainstream choice of current smart phone batteries.Compared with traditional aluminum shell batteries, soft pack polymer lithium battery cells have higher energy density and thinner appearance. Its battery cell material uses polymer electrolyte, which enables the battery to achieve more flexible packaging design while maintaining high safety. This design not only reduces the weight of the battery, but also increases the battery capacity, thereby extending the battery life of the mobile phone.The improvement of energy density is the key to the evolution of soft pack polymer lithium battery cells. Energy density refers to the electrical energy stored per unit volume or unit weight. For mobile phone batteries, higher energy density means that the battery can store more electrical energy at the same volume or weight, thus providing longer use time. In order to achieve higher energy density, battery manufacturers have continuously innovated and optimized materials, processes and designs.In terms of materials, battery manufacturers have improved the energy density of batteries by improving the positive and negative electrode materials and electrolytes of the battery cells. For example, the use of high-energy-density lithium cobalt oxide as the positive electrode material, as well as the use of lighter and thinner separators and more efficient electrolytes, all help to improve the energy density of batteries. In addition, by optimizing the packaging materials and structure of the battery cells, the weight and volume of the battery are further reduced, thereby increasing the energy density of the battery.In terms of process, battery manufacturers have improved the efficiency and performance of batteries by improving the manufacturing process and process of batteries. For example, the use of advanced coating and winding processes makes the active materials of the battery cells more evenly distributed, thereby improving the charging and discharging efficiency and cycle life of the battery. In addition, by optimizing the packaging process of the battery, the sealing and safety of the battery are further improved.In terms of design, battery manufacturers have achieved the perfect integration of batteries and mobile phone structures through innovative design ideas. For example, the use of special-shaped battery cell design allows the battery to better adapt to the spatial layout inside the mobile phone, thereby improving the battery's energy density and the phone's battery life. At the same time, by optimizing the battery's heat dissipation design, the battery's stability and safety at high power output are improved.The evolution of the energy density of mobile phone battery built-in battery soft pack polymer lithium battery cell is a process of continuous innovation and optimization. By improving materials, processes and designs, battery manufacturers continue to improve the battery's energy density and performance, thereby meeting users' demand for mobile phone battery life.
