통합 배터리 기술에는 배터리 팩 통합과 차체 통합의 두 가지 형태가 있습니다. 전자는 CTP(Cell to Pack) 기술에 반영되고, 차체 통합은 CTB(Cell to Body)/CTV(Cell to Vehicle) 및 CTC(Cell to Chassis)의 형태로 존재합니다.
배터리 통합 기술은 배터리 셀을 섀시에 직접 통합하여 전기차의 주행거리를 늘리고, 차체 강성을 높이고, 운전의 편안함을 향상시키고, 차량 내부의 Z축 공간을 최적화합니다. 미완성 통계에 따르면 최대 17개 모델(출시 및 출시 예정 포함)에 통합 기술이 적용되었으며, 그 응용은 지속적으로 심화되고 있습니다.
CTC와 CTB는 Leapmotor, BYD, Tesla, Xpeng 등 OEM의 모델에서 처음으로 채택되었습니다. 현재 Changan, Geely, Avatr 등 자동차 기업들도 CTB, CTV 등 통합 기술을 발표하고 있습니다.
2024년 4월, Geely는 자체 개발 및 자체 생산한 최신 세대 "블레이드형" LiFePO4 배터리인 Aegis Dagger Battery를 공식 발표했습니다. 이 배터리는 기존 이지스 배터리의 안전 시스템을 기반으로 더욱 업그레이드되고 개선된 것으로, CTB를 채택하여 배터리를 차체 구조의 일부로 사용하며, Geely Galaxy E5에 처음으로 탑재되었습니다.
Aegis Dagger Battery의 특징
내부 배터리 셀과 쉘은 구조용 접착제와 열전도성 구조용 접착제로 일체화되어 전체 패키지의 모드 강성과 비틀림 강성이 향상되었습니다.
예를 들어, 고강도 강철 복합재 상단 커버, 안정성이 높은 "그리드" 프레임 구조, "샌드위치" 구조의 하단 "갑옷", 극한 상황에서의 빠른 압력 방출, 이중 열과 전기 분리, "절연, 배수, 전도"의 삼상 융합, 배터리 화재 방지 등의 핵심 기술로 배터리 팩의 안전성을 크게 향상시켰습니다. 배터리 팩의 안전성이 크게 향상되었습니다.
2025년 3월, Leapmotor는 CTC 2.0 Plus를 출시했으며, CTC 2.0 Plus는 CTC 2.0에 비해 안전성, 통합성, 지능이 향상되었으며, 2025년 4월에 출시될 Leapmoon B10에 처음 탑재될 예정입니다.
Leapao CTC 2.0 Plus에는 다음과 같은 업데이트 사항이 있습니다.
더 안전한: 1,029회 안전 테스트 및 128회 성능 테스트, 50% 더 높은 측면 충격 계수, 20% 더 높은 바닥 강도, 극한의 경우에도 화재, 폭발, 열 확산 없음
더 통합적: 배터리 팩이 없는 배터리 섀시 통합 설계, 9-in-1 초집적 배터리 제어 시스템, 동급 대비 19% 향상된 전력 가용성

Power battery research: 17 vehicle models use integrated batteries, and 34 battery innovation technologies are released
ResearchInChina released Integrated Battery (CTP, CTB, CTC, and CTV)and Battery Innovation Technology Report 2025, which summarizes the development status, installation, supply layout, etc. of integrated batteries (such as CTP, CTB, CTC, and CTV) and battery innovation technologies, and predicts the development trends of integrated batteries and battery innovation technologies.
1. The application of integrated battery technologies is gradually deepening
Integrated battery technologies include two forms: battery pack integration and body integration. The former is reflected in CTP (Cell to Pack) technology, and body integration exists in the form of CTB (Cell to Body)/CTV (Cell to Vehicle) and CTC (Cell to Chassis).
Integrated battery technologies integrate the battery cells directly into the chassis to increase the range of electric vehicles, enhance body rigidity, improve driving comfort and optimize the Z-axis space in the cabin. According to incomplete statistics, up to 17 models (including those that have been released and planned to be launched) have applied integrated technologies, whose application is constantly deepening.
CTC and CTB were first seen on models of OEMs such as Leapmotor, BYD, Tesla, and Xpeng. Today, car companies such as Changan, Geely, and Avatr have also released their CTB, CTV and other integration technologies.
In April 2024, Geely officially unveiled the latest generation of self-developed and self-produced "blade-type" LiFePO4 batteries: the Aegis Dagger Battery. This battery is further upgraded and iterated on the basis of the original Aegis battery safety system. It adopts CTB and uses the battery as part of the body structure. It was first installed on the Geely Galaxy E5.
The Aegis Dagger Battery has the following features:
The internal battery cell and shell are integrated through structural glue and thermally conductive structural glue, which improves the modal and torsional stiffness of the entire package;
For example, core technologies such as the high-strength steel composite top cover, the highly stable "grid" frame structure, the bottom "armor" of the "sandwich" structure, rapid pressure relief in extreme situations, double thermal and electric separation, the three-phase fusion of "isolation, drainage and conduction", and battery fire prevention have greatly improved the safety of the battery pack.
In March 2025,Leapmotor released CTC 2.0 Plus. CTC 2.0 Plus has improved safety, integration, and intelligence compared to CTC 2.0, and will first land on Leapmoon B10 which is to be launched in April 2025.
Leapao CTC 2.0 Plus has the following upgrades:
Safer: Six-fold ("source + vision + isolation + barrier + evacuation + cooling") safety design; 1,029 safety tests and 128 performance tests; 50% higher side impact coefficient; 20% higher bottom strength; no fire, no explosion, and no heat spread in extreme cases;
More integrated: Integrated design of battery chassis without battery pack; 9-in-1 ultra-integrated battery control system; 19% more power available in the same class;
Smarter: The adaptive AI BMS battery management system can improve battery estimation accuracy by 1%, battery thermal management energy consumption by 30%, and vehicle range by 2%.
2. From 2024 to 2025, battery suppliers successively released 34 battery innovation technologies
In February 2025, BMW's sixth-generation power battery debuted globally, using large cylindrical cells for the first time. It is planned to be first applied to BMW's first next-generation model to be unveiled this year, as well as the Chinese next-generation models that will be mass-produced from 2026. BMW's upcoming industrial mass production of large cylindrical batteries will undoubtedly fuel the development of such batteries, and also provide a valuable demonstration for the continued breakthroughs in innovative power battery technologies.
According to incomplete statistics, 12 battery suppliers have successively released 34 new battery technologies since 2024, of which CATL has unveiled 7 battery technologies, which are widely used in light/heavy commercial vehicles, hybrid vehicles, buses and other models. CATL has also launched a 6C LiFePO4 battery, which can provide an additional 350 kilometers of range for vehicles in just 10 minutes of charging and will be installed on the Ultium quasi-900V platform in the future.
3. Fast charging batteries upgrade from 6C to 10C
As battery manufacturers and OEMs have deployed high-rate battery technologies, batteries have continued to iterate and break through in the field of ultra-fast charging, evolving from 6C to 10C. For example, CATL launched a 6C LiFePO4 battery, SVOLT Energy released a 6C supercharged battery and Fengxing Short Blade Battery (supercharged version), and EVE unveiled the 6C Omnicel cylindrical battery. OEMs such as FAW and Chery have also actively dabbled in the arena, especially the flash charging battery released by BYD in March this year has a charge and discharge rate of 10C, constantly breaking the industry's upper limit.
For example, in order to completely alleviate users' anxiety about charging, BYD's "flash charging battery" is comparable to "refueling" in charging speed. From the positive electrode to the negative electrode of the battery, it builds an ultra-high-speed ion channel in all directions, reducing the internal resistance of the battery by 50% with the charging current of 1000A and the charging rate of 10C. With the support of 1,000V and 1,000A, the charging power can reach 1 megawatt (1000kW), a 10-second charging offers a range up to 20 kilometers, and a 5-minute flash charging enables a range of 400 kilometers. In terms of performance, the single-module single-motor power reaches 580kW, and the maximum speed exceeds 300km/h. The "flash charging battery" was first available on Han L and Tang L which are expected to be officially launched in April.
4. Batteries for PHEVs and EREVs have become an important development direction for the power battery industry
Batteries tailored for PHEVs and EREVs aim to balance battery-electric range and fast recharging. In order to meet users' needs for daily commuting and long-distance mobility, such batteries not only should support high power output, but also must have fast charging and long lifespan. Given this, power battery manufacturers such as CATL, SVOLT Energy, and CALB are vigorously developing and launching special batteries for PHEVs and EREVs.
In January 2024, CATL released the Freevoy Super Hybrid Battery for the first time with Avatr 12. It plans to apply it to nearly 30 PHEV and EREV models from Geely, Chery, GAC, and Voyah in 2025. In July 2024, SVOLT Energy released the 800V 4C Dragon Scale Armor hybrid battery for PHEVs, which will be mass-produced in July 2025. In January 2025, SVOLT Energy released two types of batteries for PHEVs and EREVs, namely off-road batteries (for plug-in hybrid, extended-range off-road vehicles) and HEV batteries (for commercial vehicles and passenger cars). off-road batteries have been mass-produced and first installed on Tank 500 Hi4-Z.
