What are the differences between power lithium batteries and energy storage lithium batteries? In fact, power lithium batteries are also the key to power lithium-ion batteries for pure electric vehicles. Due to the limitation of volume and net weight, as well as the regulations for starting and speeding up power lithium batteries, the regulations on their characteristics are higher than those of ordinary batteries. When the specific energy is higher, the battery charge rate of the battery is faster, and the charge and discharge current is large, but the regulations for general batteries are lower; according to this specification, the volume of the power lithium battery is less than 80%, so it can no longer be used. For new energy vehicles. However, with a slight modification, it can also be used as an energy storage system. According to different application areas, power lithium batteries are mainly used in pure electric vehicles, electric vehicles and other pneumatic tools, and energy storage lithium batteries are mainly used in peak and frequency modulation power auxiliary services, renewable energy grids and micro grids. Due to different application areas, the regulations on battery performance are also different. First, as a mobile charger, the power lithium battery, under the precondition of ensuring the safety factor, the larger the volume (quality) than the energy, the longer the service life. In addition, customers also expect battery cars to be able to charge the battery safely and quickly. Therefore, out of safety factor considerations, power lithium batteries have clearly set higher regulations for energy and power. Nowadays, batteries with a charge and discharge capacity of about 1C are widely used. Most energy storage devices do not need to be moved, so there is no immediate specific energy requirement for energy storage lithium batteries. Different kinetic energy storage methods have different power requirements. For peak shaving, off-grid photovoltaic energy storage or peak time difference energy storage on the user side, battery charging or charging and discharging must generally continue for more than 2 hours. Therefore, volume rechargeable batteries are suitable for use, and the battery charging speed is ≤≤. In energy storage technology places where the uncertainty of DC deployment or renewable resources is small, the energy storage rechargeable battery has to be quickly charged within seconds to minutes, so it is suitable for ≥-2C power lithium battery applications. For some application areas that require additional radio broadcasting and peak shaving, the application of energy batteries will be more suitable. Naturally, under such conditions, volumetric rechargeable batteries can also be used. Energy storage lithium batteries have a higher service life than power lithium batteries. The service life of new energy cars is generally 5 to 8 years, while the service life of new energy storage technology projects is generally more than ten years. The service life of the power lithium battery cycle system reaches 1000~2000 times, while the energy storage lithium battery generally reaches 3,500 times. In terms of cost, power lithium batteries will encounter market competition from traditional switching power supplies, while energy storage lithium batteries will encounter market competition from traditional peak and frequency modulation technologies. In addition, because most of the operation scale of energy storage power stations is above megawatts or even gigawatts, energy storage lithium batteries are more cost-effective and safer than power lithium batteries.
