整合電池（CTP、CTB、CTC、CTV）、電池創新技術（2025）

1.整合電池技術應用逐步深入

整合電池技術有兩種形式：電池組整合和車身整合。前者體現為CTP（Cell to Pack）技術，而車身整合則以CTB（Cell to Body）/CTV（Cell to Vehicle）、CTC（Cell to Chassis）等形式存在。

電池整合技術將電池單元直接整合到底盤中，延長電動車的續航里程，增加車身剛度，提高駕駛舒適度，並優化車內Z軸空間。據不完全統計，採用該技術的車型（包括已上市和即將上市的車型）已達17款，且其應用領域仍在不斷拓展。

CTC、CTB最早應用於零跑步、比亞迪、特斯拉、小鵬等主機廠的車款上。目前，長安、吉利、阿瓦特等車企也正在引進CTB、CTV等整合技術。

2024年4月，吉利正式推出其最新一代自主研發、自產的 "刀片式" 磷酸鐵鋰電池－宙斯盾匕首電池。該款電池是原有宙斯盾電池安全系統的升級改良版。採用CTB結構，電池作為車輛結構的一部分。它首次亮相於吉利 Galaxy E5。

宙斯盾匕首砲組的特性

內部電池單元和外殼透過結構和導熱結構黏合劑黏合在一起，提高了整個封裝的模態和扭轉剛度。

例如，高強度鋼複合材料頂蓋、高穩定性 "網格" 框架結構、 "三明治" 結構底部 "裝甲" 、極端情況下的快速洩壓、雙重熱電隔離、 "絕緣、引流、傳導" 三相融合、電池防火等核心技術，大大提高了電池組的安全性。

2025年3月，零跑車發表CTC 2.0 Plus。 CTC 2.0 Plus相比CTC 2.0在安全性、整合度、智慧化方面都有提升，將率先搭載於2025年4月上市的Leapmoon B10車型。

Leapao CTC 2.0 Plus 有以下更新：

更安全：經過1029項安全測試和128項性能測試，側面碰撞係數提高50%，底部強度提高20%，即使在極端情況下也不會起火、爆炸或熱擴散

整合度更高：無電池包電池底盤一體化設計，九合一超集成電池控制系統，同級可用電量高出19%

更智慧：自適應AI BMS電池管理系統可將電池估算精度提高1%，電池熱管理能耗提高30%，並將車輛續航里程提高2%

2. 2024年至2025年，電池供應商將陸續發佈34項電池創新技術。

2025年2月，BMW第六代動力電池將首次亮相，成為全球首款採用大型圓柱形電芯的電池。該系統將首先應用於BMW今年發表的首款下一代車型，以及將於2026年開始量產的中國下一代車型。 BMW大型圓柱電池的工業化量產無疑將加速此類電池的發展，成為創新動力電池技術不斷突破的寶貴示範。

根據不完全統計，2024年以來，已有12家電池廠商陸續推出了34項新型電池技術，其中寧德時代推出了7項電池技術，廣泛應用於輕型/大型商用車、混合動力車、客車等領域。寧德時代也發表了充電10分鐘即可增加350公里續航里程的6C磷酸鐵鋰電池，並將在未來Ultium準900V的平台上應用。

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.
