Tear down solar cells and Chinese lithium batteries
Pouch cell lithium tear down video | DIY Solar Power Forum
Here is the background I have 2 120ah pouch cell lithium batteries that I originally brought for the RV. They were very poor (held 75ah each) so I replaced them and built a 280 24v battery instead. Having learnt a lot building that battery I am now thinking I could use the 2 batteries and...

New Chins 100ah Lifepo4 battery teardown
I purchased 2 Chins 100ah batteries from Amazon and tore them open hoping to find the prismatic cells that I saw in Will''s teardown video. Much to my surprise, and not a great surprise, mine was loaded with pouch cells. The assembly was well put together, and super clean. Also, way less silicone than the Zooms battery I tore apart a few weeks ago.

6 FAQs about [Tear down solar cells and Chinese lithium batteries]
Why are Chinese companies pursuing alternative batteries not based on lithium?
Lithium technologies are expected to advance quickly over the next few years. However, companies in China and beyond are frantically pursuing alternative batteries not centred around lithium, in part because the minerals needed to make the current options come from just a few countries.
Is China making solar cells?
By 2012, China had already “formed a sound manufacturing chain” for the solar photovoltaics (PV) industry. According to a government paper of that year, the country was producing more than 40 per cent of the world’s solar cells. This policy drive continued in 2015 with the launch of the “ Made in China 2025 ” strategy.
Are Chin batteries bad?
Over the last 2years or so I’ve installed over $20k worth of lithium batteries, many of which are Chins. The early ones had 0 issues from my experience. The newer ones, most specifically the ones with the heater and Bluetooth BMS are the most problematic. Issue #1, they are shipping these batteries without the cells being top balanced.
What causes irreversible loss of cyclable Lithium?
From the checkup cycles at the end of the rate capability test, an irreversible capacity loss of approx. 3% (Tesla electrolyte) and 6% (LP572) was apparent. This might be attributed to an irreversible loss of cyclable lithium at higher currents resulting from lithium plating or the continuous growth of the solid electrolyte interphase (SEI) .
Why is transparency important in lithium-ion battery research?
A key challenge in lithium-ion battery research is the need for more transparency regarding the cell design and production processes of battery as well as vehicle manufacturers. This study comprehensively benchmarks a prismatic hardcase LFP cell that was dismounted from a state-of-the-art Tesla Model 3 (Standard Range).
Is there transparency in the design and production of automotive-grade lithium-ion cells?
Conclusion This study addressed the lack of transparency in the design and production of automotive-grade lithium-ion cells by comprehensively investigating a 161.5 Ah prismatic flat wound hardcase cell from a state-of-the-art Tesla Model 3. The cell was disassembled to the material level to trace process steps and manufacturing peculiarities.
