Colloid battery belongs to a kind of lead-acid battery technology. It is not only appends the gelling agent in sulphuric acid to enable sulphate electrolyte convert into colloidal, it then used as quality causticity alloy plate, followed by a targeting if coupling agent in preparation of plate to increase the utilization rate of active substance. Therefore, colloid battery uses a lesser industry cost and create a new high capability battery from used lead-acid battery. Its discharge flat curve, higher inflection point, the energy or the power ratio is 20% larger than ordinary lead-acid battery, the length of life is commonly twice longer than ordinary lead-acid battery, higher efficiency of specification for high and low temperature.

CCTF colloid battery exclusivity as:

• 1. It has a gas phase silicon dioxide of colloidal electrolyte, inexistence acid lamination.
• 2. It has large thermal capacity, uniform heat diffusion and a wide range of working temperature.
• 3. It uses a quality causticity alloy plates, radial structure, increases the utilization rate of active substance.
• 4. It possesses a self-protection in overcharging and emptiness, its recharging ability is strong and well circulation endurance.
• 5. The battery can be placed vertically and horizontally, no leakage, safe, convenient in installation will be safe and convenient.

Due to the solar or wind power generation system, the battery must not be fully charge state, or empty. Hence, Colloid battery is the one that most fit to use on the solar and wind energy system.
