Why Not Fuel or Acid as a Generator?
So far, the commercial model for the energy storage industry has yet to take shape in the absence of a mechanism to pay for storage. High-power occasions generally use lead-acid battery, mainly used for emergency power supply, battery car, power plant surplus energy storage. Low power occasions can also be used for repeated charging of dry batteries: such as nickel metal hydride-batteries, lithium-ion batteries, etc. Now hereby the introduction to fuel/ diesel generator, lead-acid power stations, and Li-ion power stations.
Diesel is energy distilled from crude oil. In the early era, diesel generator is valuable choice by its high-cost rate. But now that new energy is coming on the market with the matured technology been developed, the shortcomings of diesel generators are very obvious by the comparison.
First, the high speed internal combustion engines generally use gasoline or light diesel fuel seasoning, and the cleanliness of the fuel requirements are strict. It is difficult to use solid fuel or poor quality fuel inside the cylinder. Second, diesel engine has been widely used in various fields of national economy, its output and possession are great, and the pollution to the environment is becoming more and more serious. For family and portable usage, then the end customers are prefer lead-acid batteries that are portable and affordable.
Lead-acid Power Stations
Lead-acid battery is the earliest industrial secondary battery, invented in 1859 has a history of more than 150 years, but the development of the industry is still in the ascendant. Compared with other battery metal materials, lead resources are rich, lead reserves and recycled lead ensure the sustainable development of lead-acid battery industry for a relatively long period of time, a large number of lead-acid battery application, will not cause a shortage of lead resources in a long time. The disadvantages of lead-acid batteries are as follows: low energy density, short cycle life, the main raw material lead is a kind of toxic substance, lead pollution risk exists in the process of battery production and recycled lead processing, and poor management may cause harm to the environment and human health.
The mass and volume energy density of the traditional lead-acid battery is low, the energy density is only about 1/3 of the lithium ion battery, 1/2 of the nickel hydrogen battery, and the volume is large, not suitable for the use of light weight, small volume. Lead is the main raw material of lead-acid batteries, which accounts for more than 60% of the battery mass, and the amount of lead used in lead-acid batteries worldwide accounts for more than 80% of the total amount of lead used. Lead is a heavy metal. Lead-acid battery manufacturing industry chain (including primary lead smelting, battery manufacturing, battery recycling, and recycled lead smelting) has a high risk of lead pollution. Poor management will cause environmental pollution and harm to human health. Moreover, the cycle life of the traditional lead-acid battery is short, and the theoretical cycle times are about 1/3 of the lithium-ion battery. While the lead-acid technology still has room to grow, lithium-ion batteries now have a better chance for future battery trends. Specially Lithium Iron Phosphate material.
Lithium Iron Phosphate (LiFePO4)
Compared with general lithium ion batteries, lithium iron phosphate batteries have better high temperature performance and absolute long life advantage. Lithium iron phosphate batteries have a longer cycle life than lead-acid batteries and ternary lithium batteries. The "long life" of lead-acid batteries is only about 300 times, and the highest is 500 times; Ternary lithium battery can be up to 2000 times in theory, and the capacity will decay to 60% when it is applied to 1000 times in practice. The real life of lithium iron phosphate battery is 2000 times, at this time there is 95% capacity, the concept of cycle life is more than 3000 times.
For the outdoor lovers and travelers, You will not miss by portable power stations, and do you know that Energizer PPS also released out portable solar systems? It will guarantee the clean and quite energy storage system for you, and it can accept solar powers. Energizer PPS320 will be your first solar power system. With a solar panel, you can have safe and green energy in off-grid, its featured by the LiFePO4 battery with a pure sine wave inverter, to be conclude, it is small size for 9 lbs, but it can generate 320Wh capacity powers. If you want the other option for larger capacity, please check out PPS2000. It generates 2150Wh LifePO4 battery, and hold for 2100 watt power. It accept 10-145 volt range, and hold up to 900 watt solar powers. It is perfectly used on the road travel or set as emergency power at home.
