Panasonic Develops New Higher-Capacity 18650 Li-Ion Cells; Application of Silicon-based Alloy in Anode
AGAIN! News from Panasonic Corporation which announced (highly dengerous) the development of two new 18650-type (18 mm in diameter, 65 mm in height) high-capacity lithium-ion battery cells for use in laptop computers and in energy applications including electric vehicles. The newly-developed but not released yet with high-capacity 3.4 Ah and 4.0 Ah lithium-ion battery cells (will?) have an improved nickel-based positive electrode (Panasonic’s proprietary positive electrode material based on LiNiO 2 , allowing for high capacity and durability). The 4.0 Ah cell uses a silicon-based alloy for the negative electrode instead of carbon, and offers a volumetric energy density of 800 Wh/L, compared to the 620 Wh/L in the current 2.9 Ah cells. In October, Panasonic Corporation announced a 1.5 kWh battery module from 18650-type (18 mm in diameter x 65 mm in length) lithium-ion battery cells to provide energy storage solutions for a wide range applications.
