NICHICON CORPORATION has entered into a technical assistance agreement with Toshiba Infrastructure Systems & Solutions Corporation to develop a small lithium-ion secondary battery applicable for SCiBTM technologies. This product is introduced into the market by both companies.
This product will be on display at the 33rd Power System exhibition, being held at Makuhari Messe from Wednesday April 18, to Friday, April 20.
Small lithium-ion secondary batteries are an essential part of the new products and services using big data, artificial intelligence and cloud computing. This includes the expansion of environmental power generation systems that convert natural energy such as light, heat, vibration and radio waves into electricity, as well as the development of car electronics used in autonomous vehicles.
This product utilizes lithium titanate for the negative electrodes, possessing high-rate* (20C maximum) rapid charge/discharge performance realizing high-density input/output that is approaching that of a capacitor. It is also durable, capable of over 18,000 charges/discharges at a rate of 10C and low temperature characteristics enabling operation even at -30°C. Furthermore, it is a safe small lithium ion secondary battery with extremely low risk of ignition or smoking due to less lithium metal separation, which causes deterioration and short circuits.
Leveraging Nichicon’s wound-product manufacturing technologies that we have developed through our strength in aluminum electrolytic capacitor production. We plan to gradually introduce into the market products that range from ultra-small with a diameter of 3 mm and a length of 7 mm, to a diameter of 12.5 mm and length of 40 mm.
Going forward, we will be developing product lines for efficient energy use to contribute to the realization of a bright future for society and the prevention of global warming.
High-rate rapid charge/discharge: The current rate when charging/discharging battery capacity in one hour is defined as 1C. The ability to charge at a rate larger than 1C indicates high-rate rapid charge/discharge performance.
