Piece, its preparation method and battery prepared therefrom.
Background technology
Winter in high latitude area, High aititude mountain area or cold, using vehicle of the lead-acid battery as startup power supply, often
Often face difficulty in starting or directly beat missing of ignition, it is necessary to independent heating starting power supply or armed state of not stopping working；And use plumbic acid
Battery usually faces frost in the winter time as communication base station power supply, it is impossible to which normal work causes signal intermittently, or even directly
Interrupt, and need frequent maintenance, and be more than ten times of lead-acid battery in these expenses of area maintenance once.Therefore, seek
It is a to be exchanged with lead-acid battery, but long lifespan, it is low temperature resistant, can the novel power supply of floating charge be a real problem of industry.
