This study aimed to investigate the feasibility of mixed use of super-capacitor and lead-acid battery in power system. The main objectives are as follow: The mathematical model is established on the basis of circuit analysis. Research the key factors affecting power system efficiency.
The result are as follows: The charging efficiency is higher when the super-capacitor is charged preferentially. Sequential charging is adopted, with stable current, small fluctuation and better battery protection performance. This study demonstrated the development and prospect of hybrid super-capacitor and lead-acid battery power storage system.
Super-capacitor can greatly increase the output power of the battery. In Experiment 1, it has been determined that the existence of super-capacitor can alleviate the irregular voltage/current impact on the battery and improves the discharge efficiency of the battery. Experiment 2 is to explore the charging sequence and its influence on the battery.
This shows that the super-capacitor plays a role in protecting the battery and prolonging the service life of the battery. The hybrid energy storage device can increase the life cycle of the combined system, reduce the emission of waste batteries, and protect the environment.
As the application of power supply, capacitor module is the output form of step-down power supply, which is the difference between lead-acid batteries. It is usually applied to voltage stabilizing circuit to ensure that the load works stably between the maximum voltage and rated voltage [ 23 ].
In contrast to secondary batteries, super-capacitors, also known as “electrochemical double-layer capacitors” (EDLC), offer higher power density and life cycle but have considerably lower energy density. Super-capacitors currently find use as short-term power buffers or secondary energy storage devices in renewable energy, power systems [ 12, 13 ].
Using capacitors to prevent surge current on lead-acid batteries?
I''m using a 300 Ah lead-acid battery bank, and a 12V->230V 1000w pure-sine inverter, to power a residential-type refrigerator. With a bit of experimentation, I''ve managed to reduce the starting power required to a peak of approximately 1500w for 400 ms, which is within what that the inverter can provide.

Battery‐Supercapacitor Hybrid Devices: Recent Progress and …
Lead–acid, Ni Cd, Ni–MH, and LIBs store energy based on redox reactions in bulk electrode materials; the electrochemical process is slow and diffusion-controlled. This enables them with high energy density (30–200 Wh kg −1) but relatively low power density (usually within 500 W kg −1) and poor cycling stability (500–2000 times).

Lead–Acid Batteries
Lead–acid batteries are comprised of a lead-dioxide cathode, a sponge metallic lead anode, and a sulfuric acid solution electrolyte. The widespread applications of lead–acid batteries include, among others, the traction, starting, lighting, and ignition in vehicles, called SLI batteries and stationary batteries for uninterruptable power supplies and PV systems.
