Researchers at the Institute of Physics at the Chinese Academy of Sciences have set a new record by packing in 711 Wh/kg of energy density inside a single battery pack. This is currently thrice the capacity of battery packs used for electric vehicles.
The battery pack’s casing provides structural integrity and protection from external impacts. Lightweight materials like aluminum are often used to reduce vehicle weight. Energy density refers to the amount of energy stored per unit weight or volume. Higher energy density translates to longer ranges for electric vehicles.
The first, named Aries, uses lithium iron phosphate (LFP) chemistry in a cell-to-pack architecture to achieve high system-level energy density. ONE’s second technology – called Gemini – embodies a “high-energy battery pack” that is coupled to the first battery and charges it to extend range.
It is a sophisticated system comprising several essential components: Types of Cells: The battery pack consists of cylindrical, prismatic, or pouch cells, each with its design advantages. Chemistry: Lithium-ion chemistries like lithium iron phosphate (LFP) and nickel manganese cobalt (NMC) dominate due to their energy density and safety.
Pack design will be critical for future solid-state batteries Solid-state batteries are touted as the endgame for battery technology, boasting high energy density and improved safety. However, pack design will still be crucial to making them viable.
Cells are grouped into modules, which are then assembled into a battery pack. This modular design allows scalability for different EV models. The BMS is the brain of the battery pack, responsible for monitoring cell voltages, managing temperature, and ensuring safe charging and discharging cycles.
