| Starting battery: Mainly used in automotive, motorcycle, fuel engine starting, marine starting, construction machinery and other starting fields. Backup battery: Mainly used for communication backup power supply, uninterruptible power supply (UPS), emergency lighting power supply and other backup power supply batteries that require high-rate discharge. Summary: 1. Sodium-ion batteries have the advantages of both lithium batteries and lead-acid batteries, and they have abundant resources, a wider temperature range, stronger charging and discharging rate, greater safety, and are more environmentally friendly. 2. With large-scale application, the low-cost advantage of sodium-ion batteries will become increasingly obvious. They will replace lead-acid batteries and become the mainstream battery product. | |||
