1、 Lead-acid battery

Main advantages:

1. Easy to obtain raw materials and relatively low prices;

2. High rate discharge performance is good;

3. Good temperature performance, able to work in an environment of -40~+60 ℃;

4. Suitable for floating charging, with long service life and no memory effect;

5. Waste batteries are easy to recycle, which is beneficial for protecting the environment.

Main Disadvantages:

1. Low specific energy, generally 30-40Wh/kg;

2. The service life is less than that of Cd/Ni batteries;

3. The manufacturing process is prone to environmental pollution and must be equipped with three waste treatment equipment.

2、 Nickel hydrogen battery

Main advantages:

1. Compared with lead-acid batteries, the energy density has significantly increased, with a weight energy density of 65Wh/kg and a volume energy density of 200Wh/L;

2. High power density, capable of high current charging and discharging;

3. Good low-temperature discharge characteristics;

4. Cycle life (increased to 1000 cycles);

5. Environmentally friendly and pollution-free;

6. The technology is relatively mature for lithium-ion batteries.

Main Disadvantages:

1. The normal working temperature range is -15~40 ℃, with poor high-temperature performance;

2. Low working voltage, with a working voltage range of 1.0~1.4V;

3. The price is more expensive than lead-acid batteries and nickel hydrogen batteries, but the performance is worse than lithium-ion batteries
