As of 2024, the difference in energy density between NMC and LFP cells is only about 30 percent (which drops to 5 to 20 percent at pack level, based on vehicles in the market). At the same time, the production cost of an NMC cell is about 20 percent higher than that of an L(M)FP cell in US dollars per kilowatt-hour (kWh), produced under the same conditions.

The applications of lithium-ion batteries (LIBs) have been widespread including electric vehicles (EVs) and hybridelectric vehicles (HEVs) because of their lucrative characteristics such as high energy density, long cycle life, environmental friendliness, high power density, low self-discharge, and the absence of memory effect [[1], [2], [3]].
To systematically solve the key problems of battery electric vehicles (BEVs) such as "driving range anxiety, long battery charging time, and driving safety hazards", China took the lead in putting forward a "system engineering-based technology system architecture for BEVs" and clarifying its connotation.
It would be unwise to assume ''conventional'' lithium-ion batteries are approaching the end of their era and so we discuss current strategies to improve the current and next generation systems
As space for battery pack size and weight of the vehicle are limited, the energy density in the cell level should be higher for attaining the longer driving range per charge. Researchers have put huge effort to increase the energy density of LIBs by finding new materials and/or modifying and combining those materials as well as optimizing
According to its 2015-2020 technical plan, BYD is focusing on LiMnPO4, which has a battery energy density of around 150wh/kg. Other suppliers are switching from LFP to ternary-based batteries.

Electric vehicle (EV) battery technology is at the forefront of the shift towards sustainable transportation. However, maximising the environmental and economic benefits of electric vehicles depends on advances in battery life cycle management. This comprehensive review analyses trends, techniques, and challenges across EV battery development, capacity
In general, energy density is a crucial aspect of battery development, and scientists are continuously designing new methods and technologies to boost the energy density storage of the current batteries. This will make it possible to develop batteries that are smaller, resilient, and more versatile. This study intends to educate academics on cutting-edge methods and
Lithium-ion batteries (LIBs) with relatively high energy density and power density are considered an important energy source for new energy vehicles (NEVs). However, LIBs are highly sensitive to temperature, which makes their thermal management challenging. Developing a high-performance battery thermal management system (BTMS) is crucial for the battery to
Government policies have advocated developing electric vehicles and new energy automobiles, which will further stimulate the booming development of battery materials and vehicular computer science towards smart mobility. With the global theme of carbon neutrality, China announced that the emission peak will be reached before 2030. By 2030,
Tailan New Energy''s vehicle-grade all-solid-state lithium batteries offer energy density twice that of other cells in the segment, empowering the Chinese battery maker to hail the cells as a
Automotive lithium-ion (Li-ion) battery demand increased by about 65% to 550 GWh in 2022, from about 330 GWh in 2021, primarily as a result of growth in electric passenger car sales, with new registrations increasing by 55% in 2022
Increasing the volumetric energy density of batteries allows electric vehicles (EVs) to travel further without increasing the size of the battery pack. Conversely, it can allow an EV to travel the same distance with a smaller battery pack, thus saving space, weight, and manufacturing costs.
Large, heavy battery packs take up space and increase a vehicle''s overall weight, reducing fuel efficiency. But it''s proving difficult to make today''s lithium-ion batteries smaller and lighter while maintaining their energy density — that is, the amount of energy they store per gram of weight.
The applications of lithium-ion batteries (LIBs) have been widespread including electric vehicles (EVs) and hybridelectric vehicles (HEVs) because of their lucrative

According to this figure, the energy density of the power battery system averaged 100 Wh/kg in 2015 and 170 Wh/kg in 2019, with a compound annual growth rate of 15%. It is expected to further increase to 350 Wh/kg by 2025.
The energy density of LIBs is crucial among the issues including safety, capacity, and longevity that need to be addressed more efficiently to satisfy the consumer’s demand in the EV market. Elevated energy density is a prime concern in the case of increasing driving range and reducing battery pack size.
Increasing the volumetric energy density of batteries allows electric vehicles (EVs) to travel further without increasing the size of the battery pack. Conversely, it can allow an EV to travel the same distance with a smaller battery pack, thus saving space, weight, and manufacturing costs.
This pioneering battery exhibited higher energy density value up to 130 Wh kg −1 (gravimetric) and 280 Wh L −1 (volumetric). The Table 1 illustrates the energy densities of initial rechargeable LIBs introduced commercially, accompanied by the respective company names .
The Li-air battery can deliver the highest theoretical specific energy of 3500 Whkg −1 but the energy density can be limited to 400–450 Whkg −1 in reality due to certain limitations and the necessity of auxiliary units.
According to the MIT's action plan to promote the automotive power battery industry, China's lithium battery energy density2 will reach 300-350wh/kg by 2020, while the battery industry has made a conservative estimate of up to 250wh/kg.
