The selection of battery energy storage routes can be considered diverse, including at least lead-acid (lead carbon batteries), lithium-ion batteries (ternary, lithium iron phosphate), supercapacitors, nanobase batteries, liquid flow batteries, sodium sulfur batteries, etc. How should energy storage users and integrators make choices in the dazzling battery technology? What principles should be used for designing solutions and long-term planning? Recently, our magazine interviewed senior figures, including multiple academician level experts, and their answer was that energy storage batteries must adhere to the principle of safety first, and the specific technical route should be combined with the scene. The next generation of batteries may be more disruptive and worth looking forward to.
What is the difference between energy storage batteries and power batteries? Some people vividly compare it to "converters" and "generators". According to different application scenarios, the former is mostly used in power systems and requires low cost and long lifespan; The latter mainly provides power for vehicles and pursues high energy density.
Lithium iron phosphate battery is a rechargeable battery, which uses lithium iron phosphate as cathode material, carbon material or graphite as cathode material, and organic solution or polymer as electrolyte. It has the advantages of high energy density, long cycle life, low self-discharge rate, and is not easy to burn. Lithium iron phosphate battery is a relatively safe lithium-ion battery, which is widely used in electric vehicles, energy storage systems, unmanned aerial vehicles and other fields.
Solar cells are a new type of energy that converts solar energy into electrical energy. It uses sunlight to irradiate a special semiconductor material, converting light energy into electrical energy, which is the working principle of solar cells. Among them, semiconductor materials need to have a special structure, with one layer being a p-type semiconductor and the other layer being an n-type semiconductor, which forms a potential difference.
