In the manganese (Mn) class lithium-ion rechargeable battery patent comprehensive strength ranking, NEC ranked first, the second and third respectively are Sanyo Electric and Mitsubishi Chemical. Patent Result (Headquarters: Tokyo) announced the involvement of manganese lithium-ion rechargeable battery (LIB) technology in the field of competition in the enterprise survey. Toshiba PA3451U-1BRSThe company has developed independently of the patent concerned about the scores for the indicators “Patent Score”. The company will test companies’patent application on the quality and amount.
Survey results show that, after the patent score and enterprise rollup, the overall average or above on account of patent total score Zhi Jin Xing’s “Syndicated news power rankings” in, NEC ranked first, the second is the Sanyo Dian Ji, the third bit is Mitsubishi Chemistry. NEC to 34 the number of patents, ranked in the top five companies in the fourth, but has a number of concerns due to the higher degree of patent, the comprehensive strength ranks the first. The largest number of patents is the comprehensive strength ranks fourth is the GS Yuasa, a total of 84.
Common lithium-ion rechargeable battery’s PA3399U-1BAS，PA3399U-2BAScathode adopt cobalt oxide (LiCoO2), but the problem is the high price of cobalt. To solve this problem, manganese lithium-ion rechargeable battery using lithium manganese oxide cheap (LiMn2O4). Compared with cobalt, manganese and relatively low prices and more readily available, thus it can reduce battery costs.
