On April 9, CATL unveiled TENER, the world’s first mass-producible vitality storage system with zero degradation within the first 5 years of use. That includes higher security, five-year zero degradation, and a strong 6.25 MWh capability, TENER will speed up giant scale adoption of vitality storage applied sciences in addition to the development of the grid scale vitality storage sector.
Whereas stopping the degradation of capability over the primary 5 years of use is a big development in growing the lifespan of batteries, CATL says the zero degradation of energy can be necessary for vitality storage energy crops that intend to satisfy the necessities of recent electrical energy techniques. Leveraging its stable electrolyte interphase and self-assembled electrolyte applied sciences, TENER has cleared roadblocks for the motion of lithium ions and achieved zero degradation for each energy and capability, guaranteeing zero progress of auxiliary energy consumption all through a full life cycle, thereby creating an “ageless” vitality storage system.
Powered by innovative applied sciences and excessive manufacturing capabilities, CATL has resolved the challenges attributable to extremely lively lithium metals in zero degradation batteries, which is able to successfully assist forestall thermal runaway attributable to oxidation response.
Till now, most vitality storage techniques housed contained in the footprint of a normal 20-foot delivery container have had a capability of 5 MWh. However CATL says its TENER system will increase that storage capability to six.25 MWh — a 30% enhance in vitality density per unit space and a 20% discount within the general station footprint, thus enhancing vitality density and effectivity by means of modern design inside a restricted area.
CATL TENER Battery Options Excessive Vitality Density
CATL’s innovative cell expertise helps the excellent efficiency of the system. TENER is supplied with lengthy service life and nil degradation cells tailor-made for vitality storage functions, reaching an vitality density of 430 Wh/L, a powerful milestone for LFP batteries utilized in vitality storage.
To attain final security in vitality storage, CATL has established a devoted, end-to-end high quality administration system that features expertise growth, proof testing, operation monitoring, and security failure evaluation. It units totally different security objectives as required by totally different eventualities, after which develops the corresponding security expertise to satisfy these objectives. So as to make sure the effectiveness of such applied sciences, CATL has constructed a validation platform to simulate the protection take a look at of vitality storage techniques in several energy grid eventualities.
After a venture is put into operation, CATL constantly screens its operation standing by means of AI-powered danger monitoring and clever early warning, calculates the failure fee of vitality storage merchandise all through their life cycle, thereby verifying the protection design objectives which it continues to optimize. Reducing the failure fee of the battery cells contained in the TENER battery storage unit can prolonged the service life of every system, leading to decrease working prices and an enhanced inner fee of return.
Vitality storage is a pivotal ingredient of the inexperienced vitality transition, the corporate says. CATL has steadfastly devoted itself to delivering world class vitality storage options for purchasers world wide. The disclosing of TENER signifies one other milestone within the firm’s ongoing dedication to vitality transition. Wanting forward, CATL will stay resolute in its pursuit of open innovation and collaborate with international business companions to forge a path of mutual prosperity as an business chief in innovation and superior expertise.

CATL & Politics
Vitality Storage Information, along with reporting concerning the new TENER battery vitality storage system from CATL, has additionally touched on the political implications of this announcement. Simply as the USA is cautious of Chinese language corporations dominating the auto business and placing home producers out of enterprise, there are comparable issues in the case of vitality storage merchandise.
Within the vitality storage market, CATL is typically described as a system integrator but in addition — maybe primarily — it sells its BESS models to different system integrators which is able to bundle these into their turnkey BESS initiatives and software program options. One such deal was introduced with US firm FlexGen in 2022.
Nonetheless, China controls nearly all of the provision chain for battery supplies and parts. If the US desires to transition to a low carbon grid, battery storage techniques with Chinese language-made elements inside might be important. It’s a conundrum, one which CATL is keenly conscious of.
That is partially right down to political obstacles that apply to vitality administration system software program made in China for initiatives within the US and elsewhere. That political stress even led to CATL grid-scale batteries being disconnected and finally decommissioned by Duke Vitality at Camp Lejeune, a Marine Corp base in North Carolina. The US army has recognized international heating as a menace multiplier and is taking steps to include renewable vitality into its amenities the place attainable.
However political issues might make that tough if nearly all of photo voltaic panels and batteries come from Chinese language sources. That’s a problem for the US and different counties anxious about Xi Jinping having management over essential US infrastructure due to digital backdoors constructed into the software program that controls the merchandise China sells to the world. That concern needs to be handled earlier than the clear vitality transition can really attain its full potential.
