A battery isn't a "power plant that stores electricity" — it's a piece of power equipment that shifts supply and demand across time. This article works through cell voltage, capacity, and C-rate, SOC/SOH, thermal runaway, safety design, grid-scale storage and V2G, and cutting-edge research such as solid-state batteries, with the math and charts.
September 10, 2026 Power Engineering PrimerHydro, thermal, nuclear, solar, and wind look nothing alike if you only compare generation methods. This piece reads frequency, supply-demand balancing, substations, transmission losses, batteries, and protection relays as a single power system, walking through the equations that determine output and stability, the equipment in service today, and where renewable-energy research is headed.
September 3, 2026 Corporate ResearchFrom EV batteries to data-center energy storage to defense and space applications, batteries are a growth field that Japan's electrical-equipment and electronic-components makers are throwing everything at — yet their origins and strategies couldn't be more different. Panasonic Energy absorbed Sanyo Electric's battery business; GS Yuasa traces back to a lead-acid battery pioneer founded in 1895; Murata Manufacturing entered the field in 2017 by acquiring Sony's battery business. This article compares all three companies' histories, financial results, products, facilities, and outlook.
