Lead-carbon battery is the most advanced technology in the lead-acid battery field, and also the development focus of the international new energy storage industry, with very broad application prospects. Energy storage battery technology is one of the key technologies restricting the development of the new energy storage industry. Energy storage fields such as photovoltaic power station energy storage, wind power energy storage, and power grid peak regulation require batteries with high power density, long cycle life, and low price. "Lithium battery" is a kind of battery with lithium metal or lithium alloy as anode material and a non-aqueous electrolyte solution. Here‘s how they compare.

Lead Carbon Battery

Advantages of lead-carbon batteries

One is fast charging, increasing the charging speed by 8 times; Second, the discharge power is increased by 3 times; Third, the cycle life has been increased to 6 times, and the cycle charging times have reached 2000 times; Fourth, the cost performance is high, compared with the price of lead-acid battery, but the cycle life is greatly improved; Five is the use of safe and stable, can be widely used in a variety of new energy and energy-saving fields. In addition, lead-carbon batteries also play the specific energy advantage of lead-acid batteries and have very good charge and discharge performance - 90 minutes can be fully charged (lead-acid batteries if charged and discharged, have a life of fewer than 30 times). In addition, the addition of carbon (graphene) prevents the sulfate of the negative electrode, which improves one factor of battery failure.

Characteristics of lead-carbon batteries

The lead-carbon battery has a discharge depth of 60% and can be recycled more than 3,000 times (the test has not been terminated).

Lead carbon battery in partial charge state (PSoC), can inhibit the negative electrode sulfate generation, the battery will not fail due to insufficient charge. (Sulfate crystals from the negative electrode are one of the causes of failure of common valve-controlled lead-acid batteries.)

Lead-carbon batteries have a wide operating temperature range: -23℃ to 60℃.

Lead carbon battery with carbon element, carbon has good thermal conductivity, so lead-carbon battery is suitable for high-temperature work.

The low-temperature discharge performance of a lead-carbon battery is higher than that of a traditional lead-acid battery. Conventional lead-acid batteries can discharge only 50% at -20℃, while lead-carbon batteries can discharge 66% at the same temperature.

Conventional lead-acid batteries * only charge at 0.2C (standard charge is 0.1C). Lead carbon battery can accept *0.6C charge (standard charge is 0.3c), charging current is three times that of traditional lead-acid battery, can greatly reduce the charge time, especially suitable for the use of solar energy system charging instability.

Most of the lead-carbon batteries are front terminal batteries or horizontal batteries. The batteries are connected in front for convenient maintenance. No maintenance space is required between battery layers, which greatly reduces the installation area.

Disadvantages of lithium batteries

Lithium battery has poor safety and explosion risk. The lithium battery made of lithium cobalt acid can not discharge with a high current and has poor safety. The circuit of the lithium battery must be protected to prevent the battery from being overcharged or discharged. Production requirements of high conditions, high cost.

It is the responsibility of each manufacturer to produce a Lead-carbon battery that meets the standards. MCA Battery Manufacture Co., Ltd. conducts many tests on Lead-carbon batteries for connection before they leave the factory, and the quality qualification rate is guaranteed.
