It has been more than 160 years since Plante invented the lead acid batteries in 1859. Before 1975, the main technology for lead acid battery is flood battery. The maintenance free lead acid battery was invented in 1970S. Later on some new materials were added to the battery plates or electrolyte to improve the performance of SLA battery. But the acid stratification is inevitable at the end of lead acid battery service life, the 100% DOD cycle life is much less than 200 for some SLA batteries. 12V120AH(BP12-120) Bi-polar battery 100% DOD cycle life can more than 400 cycles.
To make the lead acid battery performance in capacity density and power density, Yaheng started developing the Bi-polarity battery in 2021. The bi-polar battery was taken to the market in 2023. Bi-polar battery settle this problem essentially. 12V120AH(BP12-120) Bi-polar battery is Silicon GEL flat battery. The bi-polar battery is technology to make lead acid battery work properly in critical environment.
12V120AH(BP12-120) Bi-polar battery main applications:
Standby applications: UPS, Storage Power Station, Data Center,
Cyclic applications: Electric Rickshaws, Electric Vehicles, electric wheelchair
Acid stratification makes the electrolyte density lighter at the top and heavier at the bottom, which damage the grid and paste. Mature technology in Silicon GEL helps the the recombination of Hydrogen and Oxygen, avoid the loss of water can keep the density of electrolyte stable. So the bi-polarity battery keep the electrolyte a favorable status to protect the paste and grid, improve the capacity retention and cycle life
12V120AH(BP12-120) Bi-polar battery characteristics:
Horizontal arrayed plates,
No short-circuit inside the battery
OCV very stable
No electrolyte stratification
Higher power density
Higher charge acceptance, charge efficiency can be 97%, less charge cost
High discharge rate without BMS
Longer Cycle life
Lower inner resistance
Great advantage when the grid power is frequently interrupted.
