“…Moreover, the trend of CB1 and CB2 batteries showed no significant difference under 100% DoD test conditions. CB3 batteries have longer cycle life than CB1 and CB2 batteries, which may be due to the uneven dispersion of CB1 and CB2 particles on the plate [34]. In addition, the discharge time of the batteries with CB3 held steady during 300 charge/discharge cycles, but the discharge time decreased rapidly after 300 cycles, possibly due to the stratification of electrolytes and the excessive loss of water in the electrolytes [13,35].…”

The effects of carbon black specific surface area and morphology were investigated by characterizing four different carbon black additives and then evaluating the effect of adding them to the negative electrode of valve-regulated lead–acid batteries for electric bikes. Low-temperature performance, larger current discharge performance, charge acceptance, cycle life and water loss of the batteries with carbon black were studied. The results show that the addition of high-performance carbon black to the negative plate of lead–acid batteries has an important effect on the cycle performance at 100% depth-of-discharge conditions and the cycle life is 86.9% longer than that of the control batteries. The excellent performance of the batteries can be attributed to the high surface area carbon black effectively inhibiting the sulfation of the negative plate surface and improving the charge acceptance of the batteries.

“…Adding carbon materials into negative active mass (NAM) has been demonstrated as an effective method to suppress the sulfation . As the previous studies state, high conductive carbon materials like carbon black or carbon nanotubes– prolong the cycling life through enhancing the conductivity of negative electrode. Capacitive activated carbon or electrochemically active carbon materials act as tiny charge units to function as bumpers.…”

Long‐Life Lead‐Acid Battery for High‐Rate Partial‐State‐of‐Charge Operation Enabled by a Rice‐Husk‐Based Activated Carbon Negative Electrode Additive

Lead sulfation severely shortens the cycling life of lead‐acid battery under high‐rate partial‐state‐of‐charge (HRPSoC) operation. Adding carbon materials into negative active mass has been demonstrated as an effective strategy to suppress the sulfation. In this paper, rice‐husk‐based activated carbon (RHAC) with high specific surface area and high pore volume exhibits excellent performances on enhancing the discharge capacity, the dynamic charge acceptance and especially the cycling life of negative electrode of lead acid battery. Results show that the HRPSoC cycling life of negative electrode with RHAC exceeds 5000 cycles which is 4.65 and 1.42 times that of blank negative electrode and negative electrode with commercial activated carbon, respectively. These outstanding performances are ascribed to the unique architectural properties of RHAC comparing with commercial activated carbon, such as three‐dimensional porous structure for acid storage, high mesopore volume for efficient ions transport and large external specific surface area for energetic Pb deposition.

“…However, at present, the development of lead-acid batteries needs its higher specific capacity, higher specific power, and longer cycle life for hybrid electrical vehicle or electrical vehicle industry [4][5][6][7]. The present performances of lead-acid batteries are not adequate for various emerging applications.…”

Tetrabasic lead sulfate (4BS) was used as a positive active material additive for lead-acid batteries, which affirmatively affected the performance of the battery. Herein, tetrabasic lead sulfate was synthesized from scrap lead paste that was formed through the production process of the lead-acid batteries. This solves the disposing problem of the scrap lead paste that is challenging in the production of the lead-acid batteries. Scrap lead paste was first pre-treated and the 4BS with high purity and crystalline was synthesized by sintering at the temperature of 450°C and hold time of 7 h. As demonstrated by X-ray diffraction and scanning electron microscopy test and Material Studio software calculation, the purity of synthesized 4BS is higher than 98 wt%, small particles have pillar forms and are evenly distributed. Moreover, the synthesized 4BS of 1 wt% was added to the positive lead paste and then valve-regulated lead-acid battery was made after the pasting, curing and formation processes. The effectiveness of the lead-acid batteries after adding 4BS as crystal seeds was evaluated, and the 100% charge–discharge cycle life of the new battery (523 times) was about 1.4 times higher than that of general lead-acid batteries (365 times).
