Nickel-zinc battery

New type of sealed nickel-zinc battery with high energy, high-quality power and the advantages of large current discharge. This advantage makes nickel zinc batteries for electric vehicles to meet the charge in a journey, and so on climbing and accelerating demand for energy. Nickel-zinc battery is the U.S. National Energy Research Corporation (ERC) to develop and manufacture products, Xiamen plant has been A1185 battery work with the introduction of this product. Nickel-zinc battery cell is highly competitive.

Its advantages: it is to achieve its specific energy 50Wh / k more than the volume of energy more than nickel-cadmium batteries, nickel metal hydride battery is less than. Large current discharge, the battery voltage will be a broad range of balanced, yet a very long service life, cycle life ≥ 500 times. Charging time ≤ 3.5h, rapid charging ≤ 1h. Particularly worth mentioning is the charge of anti-self-discharge attenuation is very good, one month at room temperature, self-discharge is less than 30% of nominal charge.

High temperature at 50 ℃ to C / 3 discharge, the Dell battery charge attenuation ≤ 10% rated the amount of charge, and in -15 ℃, C / 3 discharge ≤ 30%. Nickel-zinc batteries with lead-acid battery has a good profile of compatibility, where the application of lead-acid batteries are the vehicles, can be used for nickel-zinc battery. From the current prices, the nickel-zinc also significantly slightly more expensive, it is believed that up until after the application of the volume, the price will come down. Contour shape and lead-acid battery compatibility make nickel zinc batteries more convenient alternative to lead-acid batteries of electric vehicles to become the ideal power supply.

Zinc-air battery

Also known as zinc-air battery zinc-oxygen battery is a metal-air battery. Zinc-air batteries to the theoretical value is more than 1350W h / kg, the specific energy has now reached 230Wh/kg, almost 8 times that of lead-acid batteries. Zinc-air battery can be seen the very large space for development. Zinc-air battery zinc electrode swap can only take the approach to “mechanical charging.” Time to replace the electrode can be completed in 3min. A new zinc electrode, “charging” time is very short, very convenient. The development of such types of batteries, battery charging station, such as eliminating the social security facilities.

This battery has a small size, charge capacity, quality, small, in a broad temperature range of normal work, and free from corrosion, work safe, reliable, low-cost advantages. Now test the battery charge capacity of lead-acid battery is only 5 times less than expected. But 5 times the amount of lead-acid battery charge has aroused the concern of the people of the world, the United States, Mexico, Singapore and some European countries have been in the postal vehicles, buses, motorcycles on trial, is also a very promising electric vehicle battery.

Flywheel battery

Flywheel battery is only 90’s of the new concept of the laptop battery, it broke through the limitations of chemical batteries, using physical methods to achieve energy storage. A certain angular velocity when the flywheel spins, it has a certain kinetic energy. Flywheel battery in its kinetic energy is converted into electricity.

High-tech type of flywheel to store energy, similar to the standard battery on. Flywheel batteries have a motor, the electric charge in the form of motor operation, driven from power, high-speed flywheel driven rotary motor, that is, power to the flywheel battery “charge” has increased the speed of the flywheel in order to increase its function; discharge , the electrical generators at the state of operation, in the flywheel

Driven by external power output to complete the mechanical energy (kinetic energy) to electrical energy conversion. When the flywheel battery power, the flywheel speed gradually decreased, the flywheel of the flywheel battery is operating in a vacuum environment, and high speed (200000r/min), the use of non-contact magnetic bearings bearings. It is said that the flywheel battery than can be up to 150W h / kg, specific power up to 5000 ~ 10000W/kg, life as long as 25 years for electric vehicle driving five million kilometers.

Battery is the power source for electric vehicles. At present, the constraints of electric vehicles is a key factor in the development of battery power is not ideal. The major electric vehicle battery performance than energy, such as over power and life. To make electric cars can compete with the internal combustion engine car, the key is to develop high-energy than the power of large, long life, low cost of the XPS M1210 batteries.

Lead-acid batteries

Lead-acid batteries have more than 100 years of history, is widely used as the internal combustion engine start-up power source for vehicles. It is also a mature electric vehicle batteries, which the reliability of a good, easy to get raw materials, cheap; than power has basically been able to meet the power electric vehicle requirements. However, it has two major drawbacks; First, low energy, accounting for the quality and size too big, mileage and shorter charge time; the other is a short life, the use of high cost.

Ni-MH battery

Ni-MH batteries are alkaline batteries, Ni-MH battery cycle life is longer, no memory effect, but higher prices. Its initial acquisition cost, although high, but because of its energy and life in the area, so the actual use of its long-term cost was not high. At present foreign produce nickel-metal hydride batteries for electric vehicles are mainly the Ovonie, Toyota and Panasonic, a joint venture. 80A h and Ovonie existing two unit cell 130A h, the specific energy of 75-80W h / kg, cycle life of more than 600 times.

This inspiron 1300 battery is installed in several electric vehicles on the trial, in which a charge for a class of vehicles can be driven 345km, there is a car traveling on a year more than 80,000 km. As a result of higher prices had not yet been mass-produced. Has developed a domestic 55A h and 100A h cell battery, than the energy of 65 W h / kg, power density than the nickel-metal hydride batteries 800W/kg.

Lithium-ion battery

Lithium ion secondary battery as a new type of high-voltage, high energy density rechargeable batteries, its unique physical and electrochemical properties, a wide range of civilian and defense applications prospects. Its outstanding features are: light weight, energy, and pollution-free, no memory effect, long service life. Weight at the same volume of cases, the lithium battery is a nickel hydrogen storage capacity of 1.6 times the battery is Ni-Cd battery 4 times, and only the current of human development and utilization of its theoretical capacity of 20% ~ 30%, development prospects are extremely bright .

At the same time, it is a real green battery, no pollution to the environment is the best electric car can be applied to the Thinkpad T60 battery. Nineties in China from the beginning of the twentieth century the development and utilization of lithium-ion battery, a breakthrough has been made so far, fully developed with independent intellectual property rights of lithium-ion battery.

Ni-Cd Battery

Application of nickel-cadmium battery only to the extent of lead-acid laptop batteries, the specific energy of up to 55W h / kg, than the power of more than 190W/kg. Fast charging, long life cycle is more than twice as much lead-acid batteries can be achieved several times in 2000, but the price of lead-acid battery for 4 to 5 times. Its initial acquisition cost, although high, but because of its energy and life in the area, so the actual use of its long-term cost was not high.

The disadvantage is that the “memory effect” likely to result in poor charge-discharge capacity of the battery can be reduced. To be in use after about ten times for a complete charge and discharge, if have a “memory effect”, should be continuous for 3 to 5 complete charge and discharge times in order to release memory. Toxic cadmium addition, attention should be paid to the use of recovery work to do a good job in order to avoid environmental pollution caused by cadmium.
