Quick view of MeritSun lithium battery development


Due to the advantages of high energy density and high operating voltage, lithium-ion batteries have become the mainstream technology for alternative energy storage and vehicles power systems.


The battery in the general sense is composed of three parts: positive electrode, negative electrode and electrolyte. Since lithium metal can react violently with air and water, and its activity is extremely high, it needs to be embedded in other materials to maintain stability. At present, the negative electrode of most lithium ion batteries is mostly composed of carbon-based materials, such as graphite.

The ratio of positive electrode materials is diverse, and different battery manufacturers have "recipes". This is also the reason why there are many kinds of lithium ion batteries on the market.

For example, the three mainstream lithium-ion batteries currently include: lithium nickel cobalt manganese (NMC) batteries favored by most traditional car companies such as BMW and Nissan, lithium nickel cobalt aluminum (NCA) batteries that Tesla admires exclusively. Considering the working environment of the battery is changeable and complicated, battery stability and safety become extremely important, and with the long-service-life feature, lithium iron phosphate batteries(LFP) is working as the most common type of lithium battery in the market. MeritSun and BYD applies the lifepo4 battery for buses, cycles more, service life longer, cruising range longer for one charge.

Tesla recently announced that Tesla's battery will "remove cobalt." What this company has to do is to change the composition of the battery's positive electrode material. Although the mystery has not been revealed, many people in the industry speculate that Tesla is seeking a transition to lithium iron phosphate (LFP) batteries, because of the three mainstream battery technologies, only lithium iron phosphate batteries are cobalt-free.

II Road signs: electric cars

In China, the market share of lithium iron phosphate batteries was as high as 55%-70% around 2014 and 2015.

From the perspective of global battery assembly, LiFePo4 batteries are superior. It is conceivable that the technical level of ternary lithium batteries will continue to improve in the future.

III Solar power system

MeritSun established its first battery manufacturing lines in 1999, and invested over USD18,000,000 upgrading technologies on Lithium Iron Phosphate(LFP) since 2012, MeritSun house-made BMS and lithium packs systems have been widely applied to various industries over 150 countries. Lithium iron phosphate batteries are the best solutions for all kind of energy storage applications in the 21st centuries.
