TOKYO -- Researchers at the University of Tokyo have developed a prototype cobalt-free lithium-ion battery that can store around 60% more energy than alternatives of the same size. Lithium-ion batteries, used to power various products from smartphones to electric vehicles, typically have electrodes that contain cobalt, nickel and manganese.
Corporate Japan used to control the market for lithium-ion batteries but in recent years has been outperformed by rivals in China and South Korea. However, the country maintains advantages in main components and materials. Asahi Kasei and Toray Industries have a combined market share of about 30 per cent for separators.
In addition to featuring electrodes and electrolytes devoid of cobalt, the new battery design has also displayed a number of advantages over conventional lithium-ion batteries. It has an energy density about 60% higher, which could equate to longer life, and it can deliver 4.4 volts, as opposed to about 3.2-3.7 volts of conventional NMC batteries.
Rechargeable batteries are a strong suit for corporate Japan, but the industry that produces them has come up against tenacious Chinese and South Korean competitors in recent years. Now Japan's hopes to remain among the global heavyweights in a market expected to be worth more than ¥2.7tn ($25bn) by 2035 rest on the ability of its engineers.
