Technology Overview

Lithium-ion batteries (LIB) are rechargeable energy storage technologies widely used in power systems to provide electricity over short durations, typically up to 6 hours. The technology includes several subcategories, primarily defined by battery chemistry.

Technical Characteristics

Lithium-ion batteries include several types, among which NMC (Nickel Manganese Cobalt Oxide), LFP (Lithium Iron Phosphate) and LTO (Lithium Titanate), used in applications ranging from consumer electronics to electric vehicles and large-scale energy storage systems. Their key characteristics are summarized below:

Abbreviation	Energy Density (Wh/kg)	Charge/Discharge Cycles	Lifetime (years)	Main Manufacturers
NMC	105–288	1,500–8,000	10–20	Samsung SDI, LG Chem, Panasonic
LFP	50–170	4,000–12,000	20	CATL, BYD, LG Chem
LTO	50–90	20,000–25,000	20	Toshiba, Leclanche

NMC batteries are widely adopted due to lower cost and large-scale production, especially in the automotive industry. LFP batteries are known for high safety, as they do not release oxygen during combustion. LTO batteries offer fast charging and long lifetime, but have higher cost and lower energy density.

Application in Vietnam

In Vietnam, lithium-ion batteries are currently deployed mainly at pilot scale and in systems integrated with renewable energy, particularly solar power, to support load balancing and enhance system flexibility. With rapidly declining costs and high efficiency, this technology is expected to become a dominant energy storage solution in the future, playing a key role as the share of renewable energy continues to increase.
