JuNeng New Energy’s “Technology Radar”: Five Cutting-Edge Directions for Next-Generation Battery PACKs
time：2026-09-04
In energy gathering new energy in the conference room of the technical committee, there is a whiteboard called "technical radar" by engineers. Five concentric circles are marked above: the inner ring is "mass-produced" lithium iron phosphate and ternary lithium, and the middle ring is "small batch verification" sodium ion battery and silicon carbon negative electrode, the outer ring is the solid-state battery and lithium sulphur battery in the "laboratory stage", and the outermost ring is the metal air cell of "concept exploration" and quantum energy storage. This radar map maps the prediction and layout of new energy sources for battery technology in the next decade.
Sodium ion Battery: "bench player" for low-cost scenarios ". The new energy source has incorporated the sodium ion battery into the middle test line for verification. Compared with lithium batteries, sodium ion batteries reduce feed stock cost by 30%-40%, and have better low temperature performance. It is suitable for scenarios such as electric two-wheeler and low-speed electric vehicles that are insensitive to energy density and extremely sensitive to costs. It is expected to achieve small batch mass production in 2027 and form a "high and low matching" product matrix with lithium batteries.
Silicon carbon negative electrode: "gradual upgrade" of energy density ". The theoretical capacity of traditional graphite anode is 372mAh/g, and the theoretical capacity of silicon material is as high as 4200mAh/g, but the volume expansion problem restricts commercialization. New energy sources and material suppliers jointly develop "silicon-oxygen composite negative electrode" to control the silicon content to 5%-10%, within the acceptable cyclic attenuation range, increase the energy density of cell by 15-20%. It is expected to be used in high-end passenger car battery pack in 2026.
solid-state battery: The Ultimate Bet of the security revolution ". The pre-research of solid-state batteries with new energy sources has entered the fourth year, focusing on the sulfide electrolyte route. At present, the energy density of laboratory samples reaches 380Wh/kg, and the cycle life is 500 times, which is still far from the 8000 times required for commercialization. But the team remained patient: "It took 15 years for the liquid lithium battery to mature, and there is no reason for the solid-state battery to be faster. Our goal is to achieve small batch applications in specific scenarios by 2030, not to catch up with the schedule. "
CTP/CTC structural innovation: "continuous excavation" of space efficiency ". Under the background that the chemical system is difficult to break through in the short term, structural innovation has become the main battlefield for cost reduction and efficiency enhancement. The CTP 3.0 technology of energy-gathering new energy has increased the space utilization rate to 75%, and the next generation CTC(Cell to Chassis) technology is being jointly developed with strategic car enterprises, the target will reduce the vehicle weight by 15%-20%.
Digital Twin BMS: software-defined "intelligent transition" of batteries ". Energy gathering New Energy is developing digital twin BMS based on electrochemical model, establishing a dedicated virtual model for each battery pack, synchronizing the physical state and chemical state in real time, and rehearsing the attenuation trajectory in the virtual space for the next few years, achieve accurate management of "one core, one policy.
The value of technical radar is not to predict which road will be successful, but to maintain many trails parallel exploration and dynamically adjust the resource ratio according to technology maturity and market changes. New energy sources believe that the real technology leadership is not betting on unidirection, but reserving enough options for uncertainty.
