汽车制造工业正在从内燃机汽车向电动汽车转型，而电动汽车的关键部分就是锂离子电池。汽车工业长期以来一直在寻找驱动新一代锂离子电池的技术。
TUBALL™单壁碳纳米管可提升能量密度、充电倍率、延长使用寿命和成本减低等锂离子电池性能指标，是解决以上主要技术难题的解决方案。
在电池充放电过程中的硅膨胀，是一个关键性的但仍需解决的问题，这现象导致硅材料开裂及颗粒之间的失去连接。
目前，TUBALL™单壁碳纳米管是能够形成长程、具韧性、高导电性网络结构的材料，即使在严重的体积膨胀和开裂情况下也能确保硅负极颗粒之间的连接性。
可防止负极失效，延长负极使用寿命，足以满足电动汽车制造商最严格的要求。
龙头锂离子电池制造商已经证明，添加TUBALL™单壁碳纳米管可使负极掺入20%以上的SiO，并打破电池能量密度的记录—高达300 Wh/kg及800 Wh/l，比市场上现有的电池高15%。
OCSiAl研发团队的研究结果表明，TUBALL™单壁碳纳米管可使负极的SiO含量提高到90%，从而确保350Wh/kg能量密度。
由于其独特的性能，单壁碳纳米管的性能优于同类导电剂，并在能量密度、安全性、放电功率以及附着力方面确保锂离子电池的性能得到重大改进。
碳黑、多壁碳纳米管等传统的正极导电材料无法达成如此高的改进程度。
OCSiAl（奥科希艾尔）作为全球单壁碳纳米管制造商，已开发用于负极和正极的应用方案。TUBALL™ BATT材料为单壁碳纳米管在水或NMP（N-甲基吡咯烷酮）中的分散体。可在标准生产过程中直接添加。

The pitch-derived soft carbon and SWCNTs provided an excellent conductivity, and the porous structure of the composite accommodated the stress produced by the Si expansion.
High thickness and specific capacity leads to areal capacities of up to 45 and 30 mAh cm−2 for anodes and cathodes, respectively. Combining optimized composite anodes and cathodes yields full cells with state-of-the-art areal capacities (29 mAh cm−2) and specific/volumetric energies (480 Wh kg−1 and 1,600 Wh l−1).
The all‐nanomat full cell shows exceptional improvement in battery energy density – 479 Wh/kg battery, and Si-anode capacity – 1166 mAh/g.
The use of SWCNT conductive additive enables graphite-free SiO electrodes with 74% higher volumetric energy and superior full-cell cycling compared to graphite electrodes.
Areal capacities greater than 10 mAh/cm2 and volumetric capacities greater than 1400 mAh/cm3 can be achieved.
Replacing Denka black with SWCNT allows to reduce the carbon content to 0.2 wt% to further increase the energy density, and 2 wt% of PVDF was shown to benefit the cycling stability due to the mitigated PVDF-induced side reactions from its direct contact with NCA particles.
