Advantages and disadvantages of 2025 button cell battery technology

2025 button cell battery has the characteristics of small size, light weight, high energy density, good sealing performance, no leakage, no memory effect, low self-discharge rate, rapid charge and discharge, ultra-long cycle life, wide working environment temperature range, safe, stable and green environmental protection, so it has a very broad application prospect in the field of communication power supply.

When 2025 button cell battery is used as negative electrode material, the potential platform is as high as 1.55V, which is more than 1V higher than traditional graphite negative electrode material. Although some energy density is lost, it also means that the battery is safer.

Since 2025 button cell battery can be used safely in high and low temperature environments, it also reflects its important advantage of wide temperature resistance (especially low temperature resistance). At present, the safe operating temperature range of Yinlong 2025 button cell battery is between -50 and 65 degrees.

Long cycle life. Compared with the graphite material commonly used in traditional lithium-ion batteries, the skeleton structure of 2025 button cell battery materials hardly shrinks or expands during the process of charging and discharging lithium insertion and extraction. It is called zero strain material, which prevents the problem of electrode structure damage caused by cell volume strain when general electrode materials extract/insert lithium ions.

The process of nano-sizing 2025 button cell battery material particles is often difficult and requires high costs. It is currently difficult to achieve large-scale industrial production.

The energy density of lithium titanate batteries is lower than that of other types of lithium-ion power lithium batteries.
